Yearn Finance

Description sourced from DeFiLlama's protocol metadata; teams submit their own copy when listing.

Yearn Finance is published as a versioned release inside the Yearn protocol family. Releases inside the same family typically share governance, brand, and large parts of the audit history, but each version can run materially different contract logic — a release labelled v2 or v3 is not just a UI refresh. Newer versions inside a family typically launch with their own audit cycle and parameter set, so do not assume the previous release's safety record carries over without checking the linked audit reports.

Fork lineage and parent-protocol relationships are tracked by DeFiLlama for security and audit-history attribution; a fork inherits the upstream design but not necessarily the upstream audits or governance.

Yearn Finance is a Yield Aggregator — a decentralised exchange where users swap assets against on-chain liquidity pools rather than a central order book. It is deployed across 7 chains, including Ethereum, Katana, Base, Optimism and 3 other chains. The codebase has been independently audited (1 report on file). DeFiLlama tracks 1 historical event for this protocol since 2020.

Yearn Finance runs a multi-chain deployment, with smart contracts live on 7 networks. Roughly 99% of its on-chain value sits on just three networks (Ethereum, Katana, Base), so a fault on any one of them would affect a large slice of users. Only one audit report is currently listed; users should weigh that against the protocol's TVL before depositing significant amounts.
