FIS is an Ethereum token that powers StaFi, a cross-chain protocol for trading staked assets as derivatives (also called “liquid staking”). Users can stake proof of stake assets via StaFi to receive “rTokens” (for example, staking 1 XTZ on StaFi might generate 1 rXTZ), which can be freely traded and redeemed for a corresponding amount of the locked and staked asset. FIS is used for staking and minting rTokens, and for paying transaction fees on the network.

Pendle is a permissionless yield-trading protocol where users can execute various yield-management strategies. Pendle's governance relies on Vote-escrowed PENDLE, also known as vePENDLE, which enables a higher degree of decentralization. By utilizing vePENDLE, PENDLE holders gain access to an array of features that increase the token's utility.
