Morpho founder Paul Frambot's proposal to split onchain vaults into "noncustodial" and "discretionary" regulatory categories drew a "self-serving" rebuke from Aave founder Stani Kulechov, with independent vault builders separately arguing the taxonomy's technical dividing line breaks down under close inspection.

The disagreement, reported by The Defiant, centers on how regulators should classify smart-contract vaults — products in which depositors commit assets to a contract that allocates capital on their behalf. Frambot's taxonomy carves the segment into two groups: contracts that execute passively without operator intervention, and contracts whose parameters a designated manager can revise, redeploy, or restrict.

Kulechov's objection targets the boundary itself. He called the split "self-serving," according to the report — a critique implying the categorization advantages whichever protocols can argue most credibly for the lighter-regulated bucket. His intervention matters because Aave operates in the same onchain credit segment where Morpho's products would be classified, and the framing determines which protocols face the lightest compliance load.

What does the timelock argument change?

Independent vault builders pushed back on the technical premise behind the split. Their point: a timelock — the delay layer between a proposed governance change and its execution onchain — does not eliminate the manager. As long as a multisig or DAO retains the authority to alter vault behavior within that window, the operator can still intervene, which the builders say keeps the product within what they consider discretionary territory.

The distinction carries regulatory weight. Vaults whose parameters an identifiable party can revise are more likely to face intermediary-style obligations under existing financial rules. Vaults framed as fully autonomous — with no admin keys and no upgrade path — would have a stronger argument for sitting outside such frameworks entirely, an outcome that materially affects registration, disclosure, and onboarding costs.

Why does the dispute matter for DeFi lending?

The exchange exposes a definitional fault line inside the onchain credit sector. Vaults and lending markets both rely on governance-controlled risk adjustments, but the framing chosen by regulators determines whether that residual authority is treated as administrative housekeeping or as managerial effort akin to a traditional fund operator.

Kulechov's critique signals that the DeFi sector's largest protocols may not converge on a unified taxonomy when engaging policymakers. His remark — aimed at a proposal from a peer founder whose project occupies overlapping product territory — suggests the next phase of regulatory dialogue will surface public disagreement rather than coordinated industry positioning.

Frambot's proposal, and the immediate response it drew from Kulechov, indicates that consensus on regulatory framing will not be automatic in forthcoming submissions to relevant authorities.

What happens next?

The pushback raises the prospect of competing industry taxonomies rather than a single agreed framework. Vault builders who reject the timelock argument are likely to publish their own technical criteria, while lending-focused protocols push for carve-outs that preserve existing governance models.

Frambot's next move — whether he revises the proposal, withdraws it, or defends it against Kulechov's objection — will set the tone for how publicly competing protocols negotiate regulatory categories in the period ahead, as policymakers weigh how to classify onchain credit products.
