Frax operates as an open-source, permissionless protocol that is fully integrated on-chain, currently functioning on Ethereum and several other blockchain networks. The primary objective of the Frax protocol is to develop a highly scalable and decentralized form of algorithmic currency to replace fixed-supply digital assets such as Bitcoin. This innovative approach represents a significant shift in the design of stablecoins. While many existing stablecoin protocols have rigidly adhered to either being fully collateralized or entirely algorithmic without any backing, Frax introduces a hybrid model. Traditional collateralized stablecoins often face custodial risks or necessitate overcollateralization on-chain. In contrast, Frax uniquely combines both backed and algorithmic components in its supply, establishing itself as the first stablecoin to feature a portion of its supply as floating or unbacked. This duality not only enhances the stability of the currency but also paves the way for a more dynamic and adaptable financial ecosystem.
