T The development of blockchain technology has introduced smart contracts,enabling digital agreements to be executed automatically without third parties. inindonesia, platforms like pt indodax highlight its legal implications based onarticles 1320 and 133 8 of the indonesian civil code (kuhperdata). the researchaddresses two key questions: do smart contracts in blockchain technology complywith contract law requirements under articles 1320 and 1338 of the indonesiancivil code, and what legal protection is available for parties harmed by smartcontract execution? this study employs a normative legal research method,utilizing secondary data such as primary, secondary, and tertiary legal materials.the data is analyzed qualitatively using deductive reasoning . findings indicate thatsmart contracts meet the validity requirements of agreements under article 1320,including mutual consent, legal capacity, a specific object, and a lawful cause.additionally, article 1338 ensures that agreements are binding and mu st beperformed in good faith. however, legal protection for aggrieved parties stillrequires clearer regulations. dispute resolution mechanisms are available throughlitigation, arbitration, and mediation, supported by the recognition of electronictransa ctions under the electronic information and transactions law (uu ite).while smart contracts are legally acknowledged, implementation requiresregulations on liabilities and dispute resolution mechanisms.
