Institutions weighing a move into decentralized lending are asking the wrong question, according to two contributors at Ajna, the on-chain lending protocol. Mike Hathaway and Joseph Quintilian argue in a new paper that the GENIUS Act's protections don't reach DeFi lending, and that stablecoin backing is beside the point when a loan's terms can be changed after the fact.
The pair frame the issue as a gap between what institutional risk reviews tend to measure — collateral quality, stablecoin reserves, market liquidity — and the actual source of exposure in DeFi: governance-controlled parameters and oracle inputs that can alter the terms of an outstanding loan.
The stablecoin question in DeFi lending
A fully backed stablecoin is often treated as a proxy for safety. Hathaway and Quintilian push back on that assumption. In a DeFi lending market, the stablecoin's reserves don't govern what happens to a borrower's position once the loan is live. A token vote can change collateral factors or interest rate models. A faulty price feed can trigger liquidations that have nothing to do with the real value of the collateral.
Neither scenario is covered by the GENIUS Act, which the contributors describe as offering no protection in this area. That matters for institutions that have treated stablecoin regulation as a proxy for DeFi lending risk. The two are separate exposures, and only one of them sits inside the Act's guarantees.
Who can change the terms
The authors' proposed reframing is blunt: instead of asking which markets are safest, ask who has the authority to change a loan's terms after the money has been lent. That question is easier to answer with on-chain records than most institutional due-diligence questionnaires allow, but it requires looking at governance structure and oracle design rather than headline collateral figures.
The distinction has practical consequences. A market with deep liquidity and a well-backed stablecoin can still carry governance risk if a token holder vote can move collateral parameters. A market with thinner liquidity but immutable parameters and multiple redundant price feeds presents a different profile. The contributors argue the second question — who controls the terms — should drive the risk assessment, not the first.
What institutions should be asking
For allocators running DeFi lending exposure, the paper points to a due-diligence checklist that starts with governance and oracle architecture. Who holds upgrade keys? Can a vote change the terms of an existing loan, or only future ones? How many price feeds does the market rely on, and what happens when they disagree? These are the questions that determine whether a stablecoin's backing actually protects a lender.
The Ajna contributors don't claim the GENIUS Act was meant to cover DeFi lending — they argue it doesn't, and that institutions should stop treating it as if it does. The gap is structural, not a drafting oversight, and it's unlikely to close through stablecoin regulation alone.
The paper lands as institutional interest in DeFi lending keeps running into compliance reviews built around traditional finance assumptions. Ajna's argument is that those reviews need a new section. Whether allocators rewrite their questionnaires before the next round of deployments is the open question.
