Autofarm launched during the 2020–21 yield farming boom and built vaults across the chains where that activity happened: BNB Chain primarily, plus Polygon, Avalanche and several others. Its fee — around 3% of harvested yield — is the lowest of any established compounder.
The record
No exploit of its core vault contracts in five years, which is a solid outcome for a protocol that operated across many chains during the period when yield farming attracted the most attacks. Individual farms it compounded have failed, which is the nature of the product rather than a fault of the aggregator.
The ecosystem problem
Autofarm's vaults live where farming yields were highest in 2021, and those ecosystems have contracted substantially. Available yields are lower, vault selection is narrower, and the protocol's development cadence has slowed noticeably. A maintenance-mode protocol is not inherently unsafe, and it does mean fewer new integrations and slower response to changes in the underlying farms.
Who should use it
Users farming on BNB Chain who want the cheapest compounding available and are farming established protocols. For newer chains or active development, Beefy covers more ground with similar economics.
