csUSDL is a yield-bearing token deployed at address 0xbeefc011e94f43b8b7b455ebab290c7ab4e216f1, observed on Base. The cs prefix indicates it is a Compound v3 supply token, meaning it represents a yield-bearing position in USDL, the USD stablecoin issued by Lido. Holding this token typically entitles the owner to the underlying USDL balance plus accrued interest generated by the Compound lending pool.
While the token shows no activity in Base’s Aerodrome liquidity pools or vote markets, it is actively utilized in Pendle’s yield-tokenization markets on Ethereum. Two active Pendle markets for csUSDL mature in July and October 2025, each holding over $23 million in TVL. These markets currently operate in a "cheap PT" regime with implied APYs between ~11.9% and ~17.3%, and feature high-leverage yield token programs via Shift.
Current on-chain data does not confirm the token’s decimal places or spot USD price. LP operators should verify the exact contract implementation and cross-chain bridge mechanics before deploying capital, as the observed Pendle activity originates from Ethereum rather than Base.
