Smart Contracts: Between Legal Innovation and Uncertainty

Smart contracts have become one of the most striking promises of blockchain technology. Self-executing agreements, written in code and triggered automatically when certain conditions are met, offer efficiency, transparency, and speed. They eliminate intermediaries, reduce transaction costs, and in theory, guarantee compliance without the need for litigation. For many, they represent the future of legal transactions.

Yet the very features that make smart contracts appealing also expose their fragility. Code is not law, at least not in the traditional legal sense. While a smart contract may execute automatically, it cannot interpret nuances, unforeseen events, or exceptions that human agreements usually contemplate. This rigidity raises fundamental questions: what happens if the code contains an error? Who bears responsibility for losses caused by a malfunction? How do courts intervene when disputes arise over something that was supposed to be “self-enforcing”?

The regulatory landscape is still developing. Some jurisdictions, such as certain U.S. states, have explicitly recognized the validity of smart contracts. The European Union, meanwhile, is debating how they fit within existing frameworks of contract law and consumer protection. The challenge lies in reconciling technological innovation with centuries-old legal principles such as consent, good faith, and fairness.

For lawyers, smart contracts are not a threat but a call to transformation. Their drafting requires collaboration between legal expertise and technical coding skills. Advising clients now demands understanding not only of contractual clauses but also of how those clauses translate into blockchain logic. Lawyers who ignore this evolution risk being left behind in a market where clients increasingly demand innovative solutions.

However, the real revolution of smart contracts may not be technological but cultural. They force us to rethink the role of lawyers, judges, and even the very notion of enforcement. If the execution of an agreement is embedded in the code itself, then the legal profession must redefine its added value: not in the mere enforcement of obligations, but in ensuring that the digital architecture of the contract reflects the principles of justice, equity, and legal certainty.

Smart contracts are neither a panacea nor a danger to be feared. They are a tool, powerful yet imperfect, that will reshape the landscape of transactions. The challenge for the legal profession is not to resist them, but to channel them wisely, ensuring that behind every line of code there remains a guarantee of rights, obligations, and above all, trust.
