Lending
Sumer is a cross-chain synthetic assets protocol with a lending and borrowing market, deployed simultaneously on a network of supported chains. Sumer enables the creation of SuTokens (Synthetic Assets of USD, ETH and BTC) to provide a credit card-like experience to users. SuTokens break cross-chain liquidity & smart contract communication barriers while enabling non-custodial, highly decentralized & secure cross-chain transfers
