Abstract: Smart contracts have shed light on a new era of contract law, which necessitates a proper legal response to address their unique characteristics, including automation, self-enforcement, coded, immutability, and irreversibility. While these features offer significant legal and practical benefits, they raised critical legal questions. The study aims to identify the legal challenges resulting from the implementation of smart contracts through an in-depth examination of various key aspects. To achieve the intended objective, the study adopted qualitative research utilising the library method and analysing data descriptively and analytically. The study revealed that applying the current conventional contract laws is inadequate and would create a bundle of unprecedented legal questions related to all the life cycle of the contracts, such as legal existence, formation and enforcement, jurisdictional issue, mechanism, unlawful activities, as well as the third parties. The study recommended establishing a specialised framework to address various issues, including the establishment of a regulatory and supervisory body, legislative clarification on various aspects of smart contractsAo such as exchange of will, place, and time, coding language and coding errors, essential functions, jurisdiction and enforcement. ADR, external partners such as Oracle and coding experts, in addition to other matters pertaining to validity and admissibility. Future studies may focus on using these questions as a way to measure the viability of their law to address the emergence of smart contracts. Keywords: Blockchain. Decentralised. Legislation.

Smart Contract Introduction Smart contracts are a new and novel form of technology introduced by Nick Szabo in 1 It introduced a unique way in which parties can conclude a decentralised, preagreed, immutable, and self-enforcing contract using an algorithm: AuIf this, then that. Ay 2 Despite the unique features offered, the lack of a secure database for deployment has impacted on the use of this unique technology. However, the actual implementation of smart contracts started with Satoshi Nakamoto's introduction of blockchain technology, which, for the first time, introduced a decentralised, immutable, and secure ledger that Nick Szabo, "Smart contracts: building blocks for digital markets," EXTROPY: The Journal of Transhumanist Thought,. 18, no. 2 Daniele Magazzeni.

E-ISSN: 2442-9899 permitted the deployment of smart contracts while mitigating the risks associated with a normal or regular database and drastically reducing costs and time. 3 Since then, smart contracts have evolved to play a major, central role in the decentralised world. A report published by Flipside in March 2024, a blockchain platform, has stated that, since January 2022, around 637. 8 million smart contracts have been deployed. 5 Moreover, the global market for smart contracts is expected to grow to reach around $73 billion by 2030, according to the report published by Grand View Research. 6 This shows a significant growth in the use of smart contracts. As a result of their capabilities and potential, smart contracts have attracted significant interest from a variety of industries and businesses. From a legal perspective, the application of smart contracts to current laws has grown recently to become one of the hot topics in the legal field. 7 Numerous studies have been conducted by legal scholars and international bodies to examine the legal status of smart contracts and the expected legal and practical challenges they face.

Hasanuddin Law Rev. : 1-27 Law (UNCITRAL). 10 These reports concurred in the potential of smart contracts, the necessity of specific legal intervention, and the need for more legally focused studies. For instance, the World Bank has confirmed that legal amendments are necessary due to the novel characteristics of smart contracts. However, they affirmed that the legal approaches would differ, as each jurisdiction possesses its own comprehension and interpretation of contract law, and they called for each country to address it independently, as a unified approach is missing. The International Bar Association agreed with the World Bank, stating that existing laws are insufficient to address the practical legal concerns of smart contracts and that some legal action will be necessary. The International Bar Association urged legislators to possess comprehensive knowledge of the matter and conduct a thorough inquiry of smart contracts to ensure adequate resolution of the issue. Also, the United Nations Commission on International Trade Law (UNCITRAL) and the International Institute for the Unification of Private Law (UNIDROIT) issued a collaborative report on the need for a prudent legislative framework that promotes technological advancement. The report addressed the lack of a unified international approach, the need to update existing laws to provide legal support for technology and adequate legal protection, particularly in relation to liability, enforcement, execution, and remedies, and proposed a legal change to facilitate the lawful use of smart contracts. Legal scholars have also examined the impact of smart contracts under traditional contract law. A study concentrated on the compatibility of European contract law with smart contracts and found that while existing contract law can address certain concerns associated with smart contracts, several legal challenges remain that pertain to the distinctive attributes of smart contracts, rendering several laws incompatible. 11 The study recommended that all European countries commence the adoption of this new technology via legislative amendments and adjustments. Another study focused on the viability of the smart contract under Indonesian law. The study concluded that despite recent amendments identifying various shortcomings and providing suggestions for legal development, the law remains inadequate. 12 This underscores the necessity for greater clarity in identifying these legal challenges, as it can aid legislators in devising effective Andreas Sherborne.

Another study examined the legal framework governing smart contracts in Uzbekistan. 14 The study identified numerous issues, including technological infrastructure and insufficient recognition and however, the article failed to deliver a thorough analysis, resulting in a gap that necessitates a more detailed and comprehensive investigation to aid legislators in enhancing current legislation. Moreover, a study was conducted to analyse the regulatory framework governing smart contracts in Malaysia through a comparative study with other jurisdictions, namely, the USA. Malta. Switzerland, and the United Arab Emirates. 15 The study presented the various approaches implemented by these countries and used them to propose recommendations for the Malaysian legislator. Despite the necessity for smart contracts to meet the main pillars outlined in the Contract Act 1950, the study concluded that current laws are inadequate in addressing various legal questions. It therefore called for urgent legislative intervention to provide clarity and promote technological This study has been supported by another study that addressed the existence of various legal obstacles, such as the enforcement and dispute resolution however, the study advocated for a targeted legislative reform with strategic legal guidance to address these issues. 16 Researchers also conducted studies in various regions, including the Middle East, highlighting the absence of specific legislation and advocating for a legislative approach to mitigate the various risks associated with the use of smart contracts. The review of various legal studies reveals that smart contracts are still in their early stages in the legal field. The lack of a unified approach led to disparities. Legislators and scholars have various views on smart contracts, leading to uncertainty and showing the need for more in-depth legal research. Moreover, there is a dearth of comprehensive 13 Happy Budyana Sari.

To achieve the intended objective, the research will provide comprehensive explanations of all essential and core technologies, which will equip the reader with the necessary information to comprehend the main issue it poses. Method This study employs a qualitative approach and uses descriptive and analytical methods to explore the legal challenges faced by smart contracts. The qualitative approach was adopted due to the novel nature of the topic under the current legal study, hence allowing for more in-depth understanding of the nuances involved. The descriptive analysis was utilised to summarise the current knowledge, including the current legal framework and challenges. 18 The analytical method, on the other hand, was also used to critically examine the findings, uncovering the underlying assumptions and legal 19 The data collection was conducted using a library research method that involved a comprehensive review of current literature in various reputable databases. The data collected primarily consisted of reports published by various institutions, scholarly textbooks, and journal articles authored by scholars to ensure the reliability of the research. The Concept and Characteristics of Smart Contracts Nick Szabo coined the term "smart contract" to refer to the rise of a new and unprecedented form of contractual agreement that ensures performance and makes breaches extremely costly by relying on an automated . elf-enforcin. , pre-determined, deterministic, and coded computer protocol. 20 Nick argues that smart contracts are a revolutionary form of a traditional contract, claiming that they are significantly more functional than their "inanimate paper-based ancestors. " Szabo's intention, as stated in the latter explanation, was not merely to introduce a new technology but also to establish a connection and introduce smart contracts as a revolution in the traditional method of 18 Hossein Nassaji, "Qualitative and Descriptive Research: Data Type Versus Data Analysis," Language Teaching Research 19, no. : 129Ae132, https://doi. org/10. 1177/1362168815572747. 19 Kimberley A.

P-ISSN: 2442-9880. E-ISSN: 2442-9899 21 Nick defines a smart contract as "a set of promises, specified in digital form, including protocols within which the parties comply with these promises. "22 This definition stands out as 'the first definition' for smart contracts, characterizing it as a promise to the involved parties, a digital format, a computer protocol, and a selfdetermined and self-executing aspect. Vitalik Buterin, the founder of Ethereum, has significantly transformed this technology by integrating smart contracts with blockchain. In his 2013 white paper. Vitalik Buterin defined a smart contract as "a mechanism involving digital assets and two or more parties in which assets are automatically redistributed among those parties in accordance with a formula based on certain data that is unknown at the time the contract is initiated. " 23 Smart contracts now incorporate a number of fundamental blockchain characteristics, including decentralisation, immutability, and non-modification. This definition also elaborates on the process and mechanism but does not assert their legality. Zhiguo and Lin William Cong proposed an additional, significant definition. They described smart contracts as "digital contracts that allow terms contingent on decentralised consensus that are self-enforcing and tamper-proof through automated execution. "24 However, to ascertain whether the term "digital contract" qualifies as a contract, it is necessary to subject it to a legal examination in accordance with national contract law. To elucidate the intricacies of the subject matter, the Free Dictionary has provided the following definition of smart contract: Aua business agreement that is recorded on the blockchain in order to verify as well as enforce its intentions and financial Ay25 This definition limits the use of smart contracts to business transactions, which seems unfeasible considering the technology's current applications beyond commerce. Ancestral dictionaries, including Oxford. Cambridge. MerriamWebster, and others, have thus far been unable to furnish a definition for smart In relation to a legislative definition, the state of Tennessee characterises a smart contract as Auan event-driven computer program that executes on an electronic, distributed, decentralised, shared, and replicated ledger that is used to automate transactions, including, but not limited to, transactions that (A) take custody over and instruct transfer of assets on that ledger. (B) create and distribute electronic assets. (C) synchronise 21 Liudmila (Lyudmil. Efimova.

The Mechanism of Smart Contracts Smart contracts operate through a distinct and proprietary mechanism that differs in several ways from traditional contracts. To practically illustrate the mechanism, if an individual wants to enter into a traditional conventional contract to purchase commodities from another party for USD 5000, they must rely on a conventional bank to transfer the funds, ensuring a secure and trustworthy transaction, and possibly a lawyer to handle the paperwork, safeguarding their rights and preventing potential violations. the case of an international . ross-borde. contract, the sender will require a substantial amount of paper to initiate an international money transfer (IMT) to the receiver's One or more intermediary banks will facilitate such transactions.

The Actual Legal Challenges Facing Smart Contracts A smart contract is a distinct method of contracting for a variety of reasons that stem from its entire lifecycle. These distinctions raise numerous legal issues that must be addressed in order to distinguish smart contracts from other types of contracts and to determine their legal status under the law. This article will highlight the most significant legal issues by categorising them.

The real issue here is that smart contracts operate completely independently of any legal obligation or restriction, including applicable laws and legislation. 34 It doesnAot abide by the provisions, or the requirements set by the civil code or other contract legislation To circumvent the issue, smart contracts must respect and adhere to applicable laws, legislation, and regulations in order to be regarded as valid legal contracts enforceable by law. 35 Regardless of whether the contract is a "smart legal contracts"36 or an "Code-only smart contract,37" and regardless of whether it is on the blockchain or not, it is critical to ensure that all forms of smart contracts comply with the current legal framework. Leaving this matter unresolved would complicate matters and increase the likelihood of future legal conflicts, as it is difficult to monitor every contract and identify a breached or void contract.

In some cases, relying on the "oracle" to ensure compliance or providing a specific smart contract that satisfies the legal requirement and is pre-secured. Another possibility is to establish an authority that will act as a smart contact checkpoint, ensuring that parties enter into enforceable, valid These suggestions can be used to tackle the legal issues related to compliance. The Jurisdictional Issue The smart contract was not designed to be used in a single geographic location, but rather as a method for conducting cross-border transactions. 40 It enables individuals . ho may or may not know one anothe. to enter into a smart contract regardless of time or place while maintaining elements of trust between them. This, however, creates the possibility of legal jurisdictional conflict in determining the applicable law to govern the contract and apply to the parties, particularly given that smart contracts may contain multiple international components. 41 The parties may be of different nationalities, reside in different countries, use different servers, and the contract's subject may be located in different locations. Typically, these issues are resolved through the private international law provisions . nder the civil cod. enacted for these purposes. Generally, traditional contracts . ritten or electroni. do not present any difficulties in identifying the applicable law by referencing the law's provisions . ivil code or electronic contract legislatio. However, the case of smart contracts will undoubtedly add a layer of complexity to the conflict. A smart contract is a collection of conditional terms stored on a decentralised, public ledger. This means that identifying the information necessary to resolve the conflict and establish jurisdiction has become a significant challenge. 43 The latter does not share the users' names44 or the contract's or parties' location45. Additionally, while laws typically give parties the freedom to choose the applicable law to the contract, this clause . he applicable law to the contrac. does not always allow parties to avoid the mandatory provisions of other countries laws. 40 Bedrettin Gyrcan, "Jurisdiction on the Blockchain," in ICBEMM 2020 (Oxfor. 11Th International Conference on Business.

London. United Kingdom. P-ISSN: 2442-9880. E-ISSN: 2442-9899 Additionally, the time of concluding the contract is another issue, as the nature of smart contracts precludes specifying the time of acceptance or issuance of the offer. Even if the deployment time was assumed to coincide with the contract's conclusion, the exchange of wills, in this case, has yet to be determined. This issue is critical because it necessitates an immediate response within international private law in order to provide a legal solution to the future conflict posed by smart contracts. Due to the novel nature of smart contracts, case law is very limited. One of the very important examples showing jurisdictional issues is the 2016 Ethereum DAO hack. An attacker, after a vulnerability in the smart contract code was exploited, diverted cryptocurrency worth about $50 million from the Decentralised Autonomous Organization. The international and decentralised nature of the Ethereum blockchain imposed the issue of identifying applicable laws and Questions arose whether such a hack was a breach of contract under U. law, a tortious act under European law, or even a legitimate action exploiting a flaw in the code under jurisdictions with less-developed cyber laws. This ambiguity delayed legal responses and highlighted the pressing need for harmonised cross-border regulations. This can be seen as a simple example to illustrate the risk of this legal issue. The Formation of a Contract The parties' free will is upheld and protected by legal systems worldwide. 47 Legislators have limited this freedom granted to a party to specific contracts that require a specific form to be concluded. This brings up one of the issues that must be addressed, particularly given that the law recognised electronic contracts as valid contracts and treated electronic writing via electronic contracts as if they were written. 48 While a smart contract is concluded electronically, its characteristics and features which is unprecedent in the field of contract law put it in different classification. It is programmed on a computer using a coding language and operates autonomously according to a predefined immutable and irreversible rule. The language used to conclude the contract is also a matter of importance. 49 Contracts are usually concluded using readable and understandable language that can indicate all the terms of the contract and shows the intentions of the parties. 50 However, smart contracts are written and concluded using various computing programming languages . esigned for smart contract. that are coded into smart contracts to self-enforce in the https://w2. com/content/dam/Deloitte/global/Documents/Energy-and-Resources/gx-oil-gas-blockchainarticle. 47 Jakub J.

University of Oslo, 2. Hasanuddin Law Rev. : 1-27 form of conditional statements. 51 As long as the smart contract is backed up by a written version of an old-fashioned contract, the latter form doesn't pose a problem. 52 All the terms in a smart contract are just a translation from a normal language into codes, and parties can go back to the original contracts to check and understand what's in the In addition, relying on a traditional contract while using a smart contract will also mean that the parties have read and agreed to all the terms and agreements before coding them into the contract. It also proves the validity of the smart contract as it is backed by a legal contract. This is what is referred to as Ausmart legal contracts. Ay Despite all the facts mentioned above, the abilities of the parties to read and understand the contract codes as a smart contract represent another legal question that must be asked, especially if the contract copy has been destroyed or lost. It Also poses an issue if the codes did not reflect the real intentions of the parties. 53 These simple examples can create a bundle of legal challenges that can affect the validity and enforceability of smart contracts. Hence, the law still needs to interfere to identify the legal position of such smart contract and whether it is accepted and considered a contract or merely a method to execute the terms agreed upon. Another question is whether those contracts . he formation of the contrac. will be accepted by the law if it was not followed by a written contract conducted by a natural or legal person . ode-only smart contrac. 54 Even if a written contract exists, most of the law has never yet accepted smart contracts as a method of contracting or identifying their legal status. Hence, both cases open the door for ambiguity in terms of their legal status, validity and recognition. Additionally, the elements of smart contracts and the way it handles the contract . he entire procedure of smart contract. also represent a highly important matter to evaluate whether smart contract can fit well within the current legal framework for contracts and meet the formation requirements. The Validity and Enforceability of Smart Contracts The validity of the smart contract is also a factor to consider. Without a third party to examine, attest to, or validate the contract, the aforementioned issues arise.

It is critical to understand the distinction between the roles of public notaries in civil and common law countries. While the role of the notary public in common law jurisdictions is limited to verifying facts, providing legal advice, and assisting parties in comprehending the contents of the documents, the notary public in civil law jurisdictions has a broader range of responsibilities, including preparing legal documents . uch as contracts, public deeds, and other legal document. , identifying and authenticating transactions and documents . uch as determining the legal status of a contract, validating a signature, or the part of a documen. 58 Having the contract notarised is a very beneficial . nd essential for certain contract. as it enables the contract to be verified, accepted and enforceable under the law. 59 This is not possible with smart contracts, which represent an unresolved The agreement via a smart contract is enforceable between the parties but not against a third party. 60 A smart contract operates outside the sphere and is not comparable to a traditional contract, which can be converted into a public deed. 61 Smart contracts assert that the existence of a blockchain enables them to obviate the need for a notary. 62 This may be true in common law jurisdictions where the public notary's authority is limited. This is not the case in civil law jurisdictions, where the notary public is charged with a slew of duties. The role of blockchain in facilitating and storing contracts and ensuring the system's integrity does not ensure the contract's legal status, the parties' capacity, the information added, or the contract's enforceability against third parties. 63 This means that it does not provide the same level of legal certainty as to legal certification or verification by a notary 55 Marcella Atzori, "Blockchain Technology and Decentralized Governance: Is The State Still Necessary?".

Thus, this matter is another serious issue that needs to be addressed in order to include smart contracts within the realm of contract legislation. The Principle of Autonomy of Contractual Will and The Freedom of Contract Both of the inter-connected principles represent a protected and core concept of contract law in most jurisdictions world-wide as they accompany the contract in all its stages, starting from creation . xpression and exchange of wil. to execution . oodwill, cause, and the subjec. Legislators, however, have imposed some limitations and restrictions over the contractual parties in certain circumstances and contracts. 64 For instance, parties have the freedom to create a contract and include any terms and conditions they agree on . elying on the freedom of contract and their wil. Nevertheless, they must adhere to the requirements and restrictions imposed by the legislators under the contract legislation such as, the ones related to the formation of the contract, the content of the contract65, or even when the law restricts the subject and cause of the contract to be lawful and in line with the law and public order. 66 In addition, the autonomous of will also allow the parties to amend, delay, or even terminate the contract whenever they agree . utual agreemen. to do so. 67 This might be one of the serious challenges facing smart contracts. The form and characteristics of smart contracts . utomation, pre-determined, immutability, and irreversibilit. pose legal challenges in relation to these principles, as the contract cannot be freely amended, cancelled, or even delayed, as parties can only make the necessary modifications prior to deployment (After deployment, parties cannot make any amendments, modifications to the smart contract. 68 In addition, smart contracts do not strictly adhere to or consider the formation and requirements imposed by contract law. 69 synchronizing these principles with smart contracts seem to be a serious legal challenge for all legislators across jurisdictions. The law of contract in jurisdictions, on the other hand, has not addressed smart contracts. Contract legislation lacked any provision which legally clarifies or discusses the legal status of smart contracts, the relationship between smart contracts and these principles 64 Most of contract legislation have included some article that limit the contract freedom either because the law requires a specific formality for certain contract or prevent any contract that is violating the contract law or/and the public order.

P-ISSN: 2442-9880. E-ISSN: 2442-9899 and the extent in which smart contract is accepted and applied . A previous legal approach has been observed by most jurisdictions upon the emergence of electronic contracts can used. To address the emergence of electronic contracts, the legislators have addressed the legal issues by the enactment of a sperate act that recognised electronic contracts and recognised electronic writing as regular writing. A similar legal movement is needed taking into consideration the distinct legal characteristics of smart contract compared to other forms of contract . n terms of its language, mechanism, supervision, etc. Even if the law recognises a smart contract as a contract based on the principle of will and the freedom of contract, the validity and enforceability of smart contracts are still not identified, hence, legal steps to address these issues must harmonised and take into consideration all the aspects. Smart contracts are also required to adhere to the limitations and restrictions imposed by the law, which can be quite challenging in certain instances. An additional issue to be considered is that smart contracts restrict the partiesAo free will after the contract's deployment, demonstrating a legal gap between principles and smart contracts. As a consequence of the above-mentioned facts, these principles need to be taken into consideration before coming to a legal approach on smart contracts. In order to solve this legal problem, the law and technology must work to find a way to address this pressing legal issue. Unlawful Activities Smart contract is conducted, facilitated and executed mostly on blockchain, thus, the possibility of using such innovation to commit criminal activities is extremely high, especially looking at the decentralised, anonymous nature and the use of cryptocurrencies as a medium of exchange . hich operate out of the legal sphere and supervision in most of the jurisdiction. 70 This link between these technologies and the high level of criminal activities via blockchain justifies the hesitation of the countries to allow the use of smart contracts until the moment. Many reports have been issued discussing the high level of criminal activities and cyber-attacks using these decentralised technologies due to the absence of the centralised governance over the system which makes it harder and more difficult for law enforcement agencies to detect any violation or illicit activities. 71 The role of law in removing the ambiguity and clarifying the legal and 70 Ari Juels.

Hasanuddin Law Rev. : 1-27 illegal activities cannot be overstated. Hence, the absence of a law represents an important legal gap and other justification for this high level of illicit activities. Above that, forming void contracts that donAot meet the legal requirements or contracts that violate the law or the public order is also possible without any detection or prevention method so far. 72 Therefore, the ability to form a smart contract for any cause . egal or illega. using blockchain and cryptocurrencies . hich are difficult to trac. represents another legal concern. 73 Many incidents have happened reported before, indicating the need for interference from various parties . egal and technological expert. in order to come up with a proper collective solution to bring this technology into the safe zone and prevent wrongdoers from using innovation for illicit activities. Hence, this issue must not be ignored while creating a legal framework for smart contracts.

This existence of a specific body will add a layer of protection and prevention for any person wishing to use smart contract for illegal purposes. The Legal Responsibility of The Technical Experts As previously stated, due to the technical nature and complexity of smart contracts, the parties frequently rely on the expertise of a third party to draught the smart contract. These experts benefit from the technical expertise required to incorporate the smart contract's terms into the contract's code. Some of them provided a "template or format" for smart contracts to follow. In some cases, it is possible for the experts to make a coding error or any other technical error that alters what the parties intended to agree on in the first place or fails to perform as intended by the parties. 75 Additionally, the developer may be running or participating in an illegal scheme. As a result, the parties may face a significant risk. as such, they may be entitled to compensation for the consequences of this critical situation, as well as an equitable allocation of risks and liabilities among themselves. 77 This legal responsibility derives from the developer core role in developing a smart contract which cannot be ignored. As a result, developers who make an error, create a smart contract for illegal purposes or even 72 Gernot Fritz and Lukas Treichl, "What's in A Smart Contract," Lexology, accessed 24 May 2022, https://w. com/library/detail. aspx?g=bac0889f-b321-444b-8227-7d3a904a83d2. 73 Jonathan Herpy, "Council Post: Smart Contracts and The Law: What you Need To Know," Forbes.

Thus, the legal responsibility of the developer is another legal issue that must be taken into consideration to preserve partiesAo rights and avoid this excuse being used to circumvent one of the parties' obligations by referring the matter to the developer. Thus, the law must be amended to clarify the developer's obligations and responsibilities. Legal Dispute After Deployment . x-ante Vs. ex-pos. The effectiveness of smart contracts opens the door for various legal issues. One of these major issues is the possibility of any legal dispute, which is possible and unavoidable in any contract regardless of its form or characteristics. 80 The majority of the contractual disputes are resolved in court or through ADR, with the judge making the final decision after hearing the facts of the case. Smart contract, however, is automated, pre-defined, and self-enforced, focusing on the ex-ante (Before the even. in which the parties code all the terms into the smart contract and let the code become the law between the parties (Code is la. These characteristics have improved the effectiveness and performance of However, it creates a serious legal challenge in the event that a future dispute arises during or after the performance. This means that in the event of fraud, duress, legal capacity, damage to the subject, or any other issue, the law has no method for protecting the rights of the parties or addressing the self-enforcement nature of smart contracts. The inability of the enforcement bodies to modify or cancel such contracts after deployment demonstrates 78 Andrew Lom. Lillian A.

Hasanuddin Law Rev. : 1-27 the absence of legal oversight over this technology. 82 In addition, the absence of legislation to guide contractors prior to deployment and to regulate the life cycle of smart contracts deprived the authority of both the ex-ante and ex-post. Therefore, this must be taken into account when addressing the legal issues surrounding smart contracts. The power of the court and other enforcement agencies must be restored and exist as disputes are unavoidable. Conclusion The implementation of smart contracts introduces various legal challenges that require immediate attention. These include aligning smart contracts with traditional contract principles, resolving jurisdictional conflicts, ensuring enforceability, managing dispute resolution and mitigating risks of unlawful activities. Legislative action is crucial, either through amending existing laws or enacting specific legislation. A regulatory sandbox could also provide a controlled environment to evaluate the effectiveness of smart contract frameworks. Other key legal measures must be considered including the establishment of a specialised regulatory body to issue certifications for cryptographic signatures, set standards for smart contracts, resolve disputes, and enforce decisions. Moreover, embedding jurisdictional parameters within the code can enhance legal certainty and facilitate conflict resolution. Additionally, recognizing smart contracts as valid methods of creating obligations and treating coding language as a representation of intent can clarify their legal standing. In the same vein, laws should address issues such as coding errors, force majeure, and unforeseen circumstances by integrating safeguards like external bodies or oracles. Courts must also have authority to enforce or rectify smart contracts using mechanisms such as kill switches or freeze functions. Decentralised alternative dispute resolution (ADR) should also be considered, given its growing relevance in the decentralised space. Furthermore, third-party contributors, such as service providers and code developers, must be accountable for their roles. Future studies should explore these challenges indepth to develop tailored solutions for diverse jurisdictions. References
