CrossFi is a decentralized asset lending and liquidity sharing protocol built on cross-chain interoperability technology. It aims to bridge the isolated assets and liquidity of all existing public chains, addressing the current liquidity barriers between assets on mainstream public chains. This provides space for asset value enhancement and liquidity expansion support for the further development of DeFi, creating a new generation of value internet ecosystem based on Web3 asset interconnectivity.

Within the CrossFi ecosystem, all synthetic assets are backed by the native asset CRFI as the sole collateral. Users can lock CRFI tokens with a collateralization ratio of at least 200% to mint basic synthetic asset units, cUSD (anchored to the US dollar value at 1:1). Once users obtain basic synthetic asset units, cUSD, they can exchange them for any advanced synthetic assets based on cUSD, such as synthetic Bitcoin, synthetic Ethereum, synthetic stocks, or synthetic asset ETFs.

Beyond its role as collateral, CRFI also serves as the native asset in the CrossFi cross-chain transfer, providing incentives for nodes across the network. It serves as the value scale and payment medium for a suite of on-chain services, including on-chain transfers, transactions, asset minting, and burning.
