Code and Contract: Why DeFi in 2026 is Finally Writing Things Down A decade into decentralised finance (DeFi), we are watching a gentle inversion of one its early slogans. “Code is law” captured the technical imagination. However, by the end of 2025, one of the clearest trends in maturing DeFi is not the phasing out of legal contract, but its quiet return. Not as a retreat from automation, but as its necessary companion. Experienced builders and sophisticated participants are increasingly comfortable with a more accurate proposition: code can execute outcomes; legal terms allocate risk, responsibility, and remedies at the edges where code cannot, and never will. In that sense, the industry is not becoming less decen - tralised because it puts into writing the terms on which it provides its services (the “Terms of Service”). It is becoming more credible to serious counterparties, more durable under stress, and, frankly, less risky to do business. This paper explores the trend towards having thought - fully drafted legal contracts in DeFi, and considers how the Terms of Service have become one of the more practical developments in this space. What the past 12 months taught the market Two episodes in the past year have tightened the mar - ket’s thinking about how far code alone can take you. First, in the Mango Markets criminal proceedings, the court drew attention to a conspicuously practical gap: there was no evidence of clear platform rules, user instructions or user-facing Terms of Service address - ing manipulation, or even spelling out basic obliga - tions such as maintaining adequate collateral. When rules are not written down, they do not vanish. They reappear later as competing stories about what the platform “must have meant”, and what a user should be taken to have promised simply by turning up and interacting. That is an expensive kind of uncertainty. It blurs the boundary between permitted use and pro - hibited conduct, and it gives both sides room to argue that the same on-chain sequence was either ordinary interaction or the manufacture of a misleading impres - sion.
Secondly, Stream Finance supplied an operational counterpart in November 2025. Public reporting in 2025 described a significant shortfall linked to an external manager, a suspension of deposits and with - drawals pending investigation, and sharp stress in its xUSD stablecoin. In moments like that, the hardest questions are rarely about the quality of the code. They are about who had authority to act, what man - date they were operating under, what was disclosed, what emergency powers could be exercised, and how losses would be allocated. Those are precisely the points a robust legal contract could address before anyone commits a meaningful portion of their balance sheet and trust to the product. Those episodes are not curiosities. They are part of a broader trend heading into 2026: serious DeFi teams are treating legal terms less as defensive boilerplate and more as product infrastructure, sitting alongside audits, risk parameters, governance design and inci - dent response planning. The appearance and the limits of code-only execution There is an undeniable elegance to code-only enforce - ment. It is fast, predictable and, at least in theory, impartial. If a borrower’s collateral ratio falls through a threshold, the protocol liquidates: no discretion, no negotiation, no excuses. Even the most sceptical regulator would acknowledge the appeal of that kind of mechanical certainty. That certainty, however, is narrow. Code is excellent at enforcing what it can observe and measure: bal - ances, thresholds, timestamps, and prices as report - ed by an oracle. It is far less capable of grappling with the questions that arise when real money is lost and real people start asking real world questions. To see why, consider what a court, regulator, exchange or institutional counterparty tends to care about after an incident. Not just what happened, but what was understood to be happening. • Intent matters because law often distinguishes between the honest use of a system and a deliber- ate attempt to create a false picture. Two users can execute the same on-chain steps, with radically
