USDf is a token deployed on Base at address 0xfa2b947eec368f42195f24f36d2af29f7c24cec2. While the exact issuer and underlying collateral mechanics are not detailed in the available data, the naming convention and its integration with Pendle suggest it functions as a stablecoin or stablecoin derivative. The token currently lacks verified on-chain metadata for decimals and USD pricing, and it shows no presence in Aerodrome liquidity pools or Base vote markets.
USDf is primarily observed in Pendle markets on Ethereum mainnet, where it is tokenized into principal and yield components with maturities extending into 2026. These markets report a combined TVL of approximately $1.27 million, with yield programs like Falcon actively participating. The coexistence of "cheap_yt" and "cheap_pt" regimes indicates that market participants are actively trading the token's future yield streams, a structure commonly used for yield-bearing stable assets.
For liquidity providers, the primary consideration is the absence of transparent pricing and decimal information, which complicates accurate position sizing and pool valuation. Additionally, because USDf's yield tokenization is concentrated on Ethereum mainnet rather than Base, cross-chain bridge exposure and potential liquidity fragmentation between chains should be carefully evaluated before deploying capital.
