Yield Basis

Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.

REJECTED ON UNDISCLOSED CONTROL AND A DIRECTLY RELEVANT FOUNDER TRACK RECORD. Yield Basis, founded by Curve Finance founder Michael Egorov, auto-leverages Curve LP positions funded partly by borrowed crvUSD to give BTC liquidity providers impermanent-loss-free spot exposure — a real technical mechanism confirmed through the project’s own GitHub repositories and DefiLlama’s TVL methodology. But no legal entity name or jurisdiction was found anywhere, no admin key, multisig, or pause-authority structure was disclosed, no audit of Yield Basis’s own contracts was located, and the exact leverage ratio and liquidation parameters governing the core mechanism could not be independently confirmed — the project’s own site and docs were unreachable throughout this review. Separately, Egorov has a demonstrated, twice-realized pattern of running large personal leveraged CRV positions that created market stress: a near-liquidation in August 2023 that he unwound via OTC sales, and an actual liquidation in June 2024. A new protocol he founded that is itself explicitly leverage-based compounds rather than mitigates that founder-risk profile.

Kill criteria: the events that revoke this verdict
• A named legal entity, incorporation jurisdiction, and control or admin-key structure are publicly disclosed
• An independent, primary-source security audit of Yield Basis’s own contracts is published
• The exact leverage ratio, rebalancing trigger, and liquidation parameters are confirmed from primary documentation
• Twelve consecutive months with no founder-level leveraged-position stress event that could plausibly affect Yield Basis’s own Curve DAO dependency

The research file

Mechanism

Yield Basis auto-leverages a BTC/crvUSD-style Curve liquidity position, borrowing crvUSD to fund the leverage and automatically rebalancing to neutralize impermanent loss for the underlying BTC liquidity provider — confirmed through the project’s own GitHub organization, whose core repository is described as an ”autoleverage AMM and leveraged liquidity token,” and through DefiLlama’s stated TVL methodology, which nets Curve LP token value against borrowed crvUSD debt. Launch required a Curve DAO governance vote to establish the underlying crvUSD borrowing facility, confirming Yield Basis is formally separate from Curve but structurally dependent on it. The exact target leverage ratio and rebalancing trigger frequency could not be confirmed from any primary source, since both yieldbasis.com and its documentation site were unreachable throughout this review.

Undisclosed control and no confirmed audit

No legal entity name, incorporation jurisdiction, admin key structure, multisig composition, or pause and freeze authority was found in any source this review could access for Yield Basis’s own contracts. DefiLlama’s audit field for this protocol shows zero, and no news coverage or documentation referenced a named audit firm having reviewed the codebase. For a protocol whose core mechanism involves borrowed leverage and automated rebalancing, the absence of any confirmed audit or control disclosure is independently disqualifying.

The founder’s leveraged-position history

In early August 2023, following the Curve reentrancy exploit that crashed CRV’s price, Egorov’s large personal CRV-collateralized borrowing positions across Aave, Fraxlend, and other lenders approached liquidation; he sold roughly 178M CRV tokens in OTC deals worth about $42M to delever and avoid a cascading liquidation that market participants worried could have spread bad debt into Aave’s money market. He settled the Aave position entirely by late September 2023. Less than a year later, in June 2024, Egorov was actually liquidated amid a sharp CRV price decline, reportedly losing a large position. This is a real, twice-documented pattern of a founder running concentrated, highly leveraged personal exposure against his own project’s governance token, directly relevant to evaluating a new protocol he has founded whose core design is itself leverage-based.

Redemption and track record

Redemption necessarily requires unwinding the leveraged Curve LP position and repaying the crvUSD debt, meaning standard leveraged-position liquidation risk applies if the BTC-side collateral value falls relative to the debt — no specific liquidation threshold or loan-to-value figure was confirmed from a primary source. Tracked TVL grew from roughly $3M in early 2025 to a peak near $247M in August 2025, settling around $134-144M by late 2025 into 2026, with reported trading volume and fee generation continuing to grow through mid-2026. No exploit or incident specific to Yield Basis itself was found in this review’s search coverage.

Comparison and decision

Against standard Curve liquidity provision, Yield Basis adds automated leverage and an undisclosed control layer in exchange for eliminating impermanent loss — a real engineering achievement if the mechanism performs as designed, but one this registry cannot verify without the basic entity, audit, and control disclosures every comparable leveraged-yield product in this backlog has been required to provide. The founder’s own leveraged-position history is an independent reason for caution that would apply even if those disclosure gaps were closed.

Inherited controls

The verdict above grades the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The least safe layer sets the position’s grade, and the position table names which one that is.
