Akan tetapi, UNCITRAL Model Law on Electronic Commerce sebagai soft law memberikan kebebasan bagi negara untuk memberlakukan undang-undang sendiri mengenai keabsahan smart contract. Mengambil dari dua contoh negara, yaitu Indonesia dan Singapura, peneliti melakukan studi komparatif mengenai ketentuan kontrak elektronik pada Undang-Undang Nomor 11 Tahun 2008 jo. Undang-Undang Nomor 19 Tahun 2016 tentang Informasi dan Transaksi Elektronik dan Peraturan Pemerintah Nomor 80 Tahun 2019 tentang Perdagangan Melalui Sistem Elektronik dan membandingkannya dengan Electronic Transactions Act 2010. Dengan menggunakan metode penelitian yuridis normatif serta pendekatan perbandingan norma, perundang-undangan, dan konseptual, penulis mengumpulkan data yang kemudian menggunakan Teknik penafsiran interpretasi gramatikal dan sistematis untuk memecahkan isu hukum. Dari hasil penelitian, penulis memperoleh jawaban yaitu solusi identifikasi ketidakjelasan pengakuan validitas karakteristik self-executing smart contract dalam Article 11 UNCITRAL Model Law on Electronic Commerce dapat terjawab apabila adanya paragraf baru yang mengakui validitasnya. Akan tetapi, para pihak yang menggunakan smart contract dalam transaksi e-commerce dapat merujuk kepada hukum nasional apabila para pihak menggunakannya dalam cakupan nasional. Sedangkan, apabila smart contract digunakan dalam transaksi lintas batas, maka suatu klausula choice of law dan choice of jurisdiction wajib dibubuhkan bersama dengan smart contract.

However, UNCITRAL Model Law on e-commerce as a soft law gives the authority to states to set their own laws concerning smart contracts. With the comparison between Indonesia and Singapore, this research compared the provisions regarding e-contracts as in Law Number 11 of 2008 in conjunction with Law Number 19 of 2016 concerning Electronic Information and Transactions and Government Regulation Number 80 of 2019 concerning Electronic System-based Trade and Electronic Transactions Act 2010. With normative juridical methods, and normative, statutory, and conceptual approaches, this research collected data based on grammatical and systematic interpretations to solve the issue. The research results have found that there should be a new paragraph in Article 11 of the UNCITRAL Model Law on Electronic Commerce to recognize the validity of self-executing characteristics in a smart contract. Those using a smart contract, however, can refer to national laws within a national scope, while the use at the international level requires the parties concerned to refer to the choice of law and choice of jurisdiction for a smart contract.
