Yield Basis

This review is adverse because Yield Basis does not disclose its controls, and its founder has a directly relevant 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. The project’s own GitHub repositories and DefiLlama’s TVL method confirm this real technical mechanism. 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 twice run large personal leveraged CRV positions that caused market stress: a near-liquidation in August 2023 that he unwound through OTC sales, and an actual liquidation in June 2024. His founding of a new protocol that is explicitly leverage-based adds to this founder-risk profile instead of reducing it.

Review triggers: events that reopen the 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

Confirmed 2026-09-25: 37 days quiet, TVL $137M (-14% in 30 days), no open item. Holds to 2027-09-26 while the watch stays quiet.

The research file

Mechanism

Yield Basis auto-leverages a BTC/crvUSD-style Curve liquidity position. It borrows crvUSD to fund the leverage and automatically rebalances the position to neutralize impermanent loss for the underlying BTC liquidity provider. The project’s own GitHub organization confirms this mechanism, describing its core repository as an “autoleverage AMM and leveraged liquidity token.” DefiLlama’s stated TVL method also confirms it by netting Curve LP token value against borrowed crvUSD debt. Launch required a Curve DAO governance vote to set up the underlying crvUSD borrowing facility. This confirms that Yield Basis is formally separate from Curve but depends on it. No primary source confirmed the exact target leverage ratio or how often rebalancing is triggered because both yieldbasis.com and its documentation site were unreachable throughout this review.

Undisclosed control and no confirmed audit

No source this review could access named a legal entity, incorporation jurisdiction, admin key structure, multisig members, or pause and freeze authority for Yield Basis’s own contracts. DefiLlama’s audit field for the protocol shows zero, and no news coverage or documentation said that a named audit firm had reviewed the codebase. The core mechanism uses borrowed leverage and automated rebalancing. The lack of any confirmed audit or disclosure of who controls the contracts is enough on its own to reject it.

The founder’s leveraged-position history

In early August 2023, after the Curve reentrancy exploit 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 reduce his debt and avoid a cascading liquidation that market participants feared could 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 during a sharp CRV price decline and reportedly lost a large position. These two documented events show a founder running concentrated, highly leveraged personal exposure against his own project’s governance token. That record bears directly on a new protocol he founded whose core design also relies on leverage.

Redemption and track record

Redemption requires the protocol to unwind the leveraged Curve LP position and repay the crvUSD debt. Standard leveraged-position liquidation risk therefore applies if the BTC-side collateral value falls relative to the debt. No primary source confirmed a specific liquidation threshold or loan-to-value figure. Tracked TVL grew from roughly $3M in early 2025 to a peak near $247M in August 2025, then settled around $134-144M by late 2025 into 2026. Reported trading volume and fee generation continued to grow through mid-2026. This review’s search coverage found no exploit or incident specific to Yield Basis itself.

Comparison and decision

Compared with standard Curve liquidity provision, Yield Basis adds automated leverage and a control layer that it does not disclose in exchange for eliminating impermanent loss. That is a real engineering achievement if the mechanism works as designed. But this registry cannot verify it without the basic entity, audit, and control details required from every similar leveraged-yield product in this backlog. The founder’s own history with leveraged positions gives a separate reason for caution that would remain even if the project closed those disclosure gaps.

Inherited controls

The research above describes the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The layer with the most administrative power sets the position’s effective control; that describes control, not quality or suitability.
