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.

Celestia is a modular data availability network built with the Cosmos SDK. Celestia’s unique architecture offers developers a platform to build highly scalable decentralized applications and rollups. As Celestia directly provides the data availability and consensus layer, and Optimint provides the settlement layer, developers only have to focus on building the execution layer. TIA is the native token of Celestia, and can be used for gas fee payment, network governance, and staking participation.
