Cozy Earn Review 2026: Euler Vault Protection

Cozy Earn routes deposits into Cozy-curated Euler lending vaults and offers layered protection against losses. The protection is a useful extra risk layer, not a guarantee, and vault-specific terms and fees should be checked before depositing.

Our verdict on Cozy Earn

5.8/10

Cozy Earn may suit Ethereum users who want exposure to lending vaults and value an additional loss-protection layer. Its main distinction is routing deposits into Cozy-curated Euler vaults with first-loss capital intended to protect covered depositors. That protection is conditional on the available capital and vault terms, not a promise that deposits cannot lose value. Fees and detailed audit information are not stated on the product homepage, so users should verify each vault's terms before committing funds.

What is Cozy Earn?

Cozy Earn is an Ethereum lending product that routes deposits into Euler vaults curated by Cozy. Its Safety Module is designed to add layers of protection for vault depositors, with first-loss capital intended to absorb losses before they reach protected users.

Cozy Earn also supports borrowing USDC against WBTC, cbBTC and wstETH, with the Cozy Disaster Reserve described as a protection layer. The product uses smart contracts, and users interact directly with them while retaining custody of their assets.

Protection does not remove the risks of smart-contract failures, lending-market losses or collateral liquidations. Cozy does not publish fee details in its product description, so users should review the terms and transaction details for each vault before using it.

How Cozy Earn works

Cozy Earn routes deposits into Euler lending vaults curated by Cozy. Lending vaults pool supplied assets and make them available to borrowers under the vault's rules; depositors take on risks from the underlying contracts, borrowers and collateral markets. Cozy Earn is listed on Ethereum.

The Cozy Safety Module adds a protection layer intended to absorb eligible losses before they reach protected depositors. This protection relies on capital being available in the relevant layers and does not make deposits risk-free. Cozy also offers borrowing of USDC against WBTC, cbBTC and wstETH, with the Cozy Disaster Reserve described as providing protection; borrowers still face collateral and liquidation risks.

Pros and cons

Layered protection is designed to take losses before they reach covered depositors.
Self-custody interaction rather than centralized custody of user assets.

Watch out for

Protection depends on the available capital in the Safety Module and should not be treated as a guarantee against losses.
Depositors remain exposed to smart-contract, lending-market, collateral and liquidation risks.
Cozy does not publish fee details in its product description.
Two audits are listed, but their names, scope and findings are not stated on the Cozy Earn homepage.
Vault-specific rates, limits and protection terms need to be checked before depositing.

Cozy Earn fees

Cozy Earn does not publish fee details in its product description. Check the relevant vault and transaction details in the app before depositing or borrowing, since terms can differ by vault.

Is Cozy Earn safe?

Cozy's protocol listing shows two audits, but the Cozy Earn homepage does not state the audit names, scope or findings. An audit is not a guarantee against vulnerabilities, and the product remains exposed to smart-contract and lending-market risks.

Protection depends on available capital and the terms of the relevant vault; it may not cover every loss. Borrowers also face collateral-value changes and liquidation risk. Cozy Earn does not state a licensing status in its product description.
