At a glance
Pendle ↗ and Yearn Finance ↗ operate in the same yield category but serve different DeFi users. Pendle is a yield-trading venue that splits yield-bearing assets into Principal and Yield Tokens, attracting $0.96B in TVL across 8 chains. Yearn, the original yield aggregator, manages $0.14B across 6 chains with its multi-strategy v3 vaults. Pendle appeals to active traders betting on yield fluctuations, while Yearn targets depositors seeking automated compounding.
Key differences
Pendle and Yearn diverge on three critical dimensions: mechanism, scale, and chain footprint.
Mechanism: Pendle tokenizes future yield, allowing users to buy discounted PTs or speculate with YTs. Yearn automates yield generation by rotating capital across strategies in one vault. Pendle’s design suits active management; Yearn’s is fully passive.
TVL: Pendle’s $0.96B dwarfs Yearn’s $0.14B. The gap reflects Pendle’s centrality to points/airdrop farming and institutional yield trading.
Chain support: Pendle spans Ethereum, Arbitrum, BNB, Optimism, Mantle, Base, Sonic, and Berachain (8 networks). Yearn covers Ethereum, Arbitrum, Optimism, Base, Polygon, and Fantom (6). Pendle’s broader reach gives it more liquidity sources.
Launch: Yearn (2020) predates Pendle (2021) by one year, but Pendle overtook it in TVL and mindshare.
Security and track record
Pendle has no recorded protocol exploit. Pendle’s audits come from Ackee, WatchPug, and Spearbit. Yearn’s are by Mixbytes, ChainSecurity, and Trail of Bits. Yearn’s current v2/v3 vaults have not been breached, but a deprecated legacy iearn (yUSDT) contract was exploited for roughly $11.5M in April 2023 — a reminder that its older code carried risk. Given Yearn’s longer operational history (since 2020), it carries a longer battle-testing record, while Pendle’s TVL and complex token mechanics have held up without any security breach.
Fees and costs
Neither facts blob includes current fee structures. Pendle’s fees typically include a swap fee on its AMM and a protocol fee on YT redemption; Yearn charges a performance and management fee on vault returns. Exact rates vary by asset and chain—check [official Pendle docs](https://docs.pendle.finance) and [Yearn vault pages](https://yearn.fi/vaults) for live values.
Which should you choose
Pick Pendle if you want to trade future yield, farm points or airdrops, or access deep liquidity for LST/LRT strategies. The protocol’s $0.96B TVL and 8-chain presence make it the superior venue for yield speculation and capital efficiency.
Pick Yearn if you prefer a set-and-forget vault that auto-compounds returns. Its v3 vaults with permissionless strategies offer simplicity, and its governance token YFI provides exposure to the aggregator’s fee revenue.
Verdict
Pendle and Yearn are not direct competitors; they cater to different yield strategies. With $0.96B in TVL and a dominant position in yield tokenization, Pendle is the stronger protocol by market metrics. However, Yearn remains simpler and more proven for passive aggregator strategies. Choose based on whether you want active control (Pendle) or hands-off compounding (Yearn).
