Notional is a decentralized protocol for fixed rate, fixed term lending and borrowing of crypto assets on Ethereum. Users can lend or borrow stablecoins at fixed rates of interest for terms of up to six months using a variety of assets as collateral. Notional achieves fixed rate lending via a primitive called fCash, which is redeemable for an underlying currency like DAI upon the fCash token's maturity date. Notional operates specialized liquidity pools that allow users to efficiently trade cash for fCash and vice versa. The exchange rate that a user receives on their trade implies a fixed rate of interest from the time of trade until the fCash token's maturity.Notional is flexible and configurable. The protocol can add additional assets for lending and borrowing, additional collateral types, and additional maturities beyond six months. The community intends to broaden Notional's scope over time to include a wider array of supported assets and extended available maturities.Notional prioritizes security. The protocol team works with industry leaders to ensure that the smart contracts are technically secure and that the economic assumptions applied in the protocol's design are sound.
