将 StaFi FIS 兑换为 Polygon MATIC

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.

Polygon was formerly called Matic Network. Polygon (MATIC) is an Ethereum token that powers the Polygon Network, a scaling solution for Ethereum. Polygon aims to provide faster and cheaper transactions on Ethereum using Layer 2 sidechains, which are blockchains that run alongside the Ethereum main chain. Users can deposit Ethereum tokens to a Polygon smart contract, interact with them within Polygon, and then later withdraw them back to the Ethereum main chain. The MATIC token is used to pay transaction fees and participate in proof-of-stake consensus.
