What is DeFi Dollar (USDFI)?
DeFi Dollar is a decentralized financial protocol that functions as an on-chain banking layer within the Web3 ecosystem. It is primarily built as an evolution of the Liquity V2 architecture, focusing on providing a highly resilient and censorship-resistant stablecoin known as USDFI. The protocol aims to offer a comprehensive suite of financial services, including borrowing, lending, and yield generation, all integrated into a single platform. The USDFI token serves as the native stablecoin of the ecosystem. It is designed to be a decentralized medium of exchange that maintains its value relative to the US dollar through an over-collateralization model. Unlike many other stablecoins that rely on centralized assets or real-world reserves, USDFI is backed by a basket of decentralized crypto assets. These typically include tokens from well-established protocols such as Aave, Uniswap, and Chainlink. One of the key features of the protocol is its permissionless minting process. Users can generate USDFI by depositing accepted collateral into smart contracts. The system utilizes a market-driven monetary policy where interest rates are influenced by users to help maintain the stablecoin's stability. Additionally, the protocol includes specialized mechanisms, such as stability pools and a redemption system, to ensure that the token remains fully backed by on-chain assets and can be converted at any time. Beyond the stablecoin itself, the DeFi Dollar ecosystem incorporates utility and governance tokens, such as DEFI or STABLE, depending on the specific implementation or network. These tokens allow participants to influence the protocol's economic parameters, direct the allocation of fees generated by the system, and participate in the governance of the platform. The project emphasizes immutability, meaning that its core smart contracts are designed to operate without central intervention, enhancing the transparency and trustless nature of the platform. Overall, the project positions itself as a multichain native banking layer that simplifies the user experience by bringing various financial functions under one roof. It focuses on high-level security, utilizing on-chain proof of reserves and professional audits to maintain integrity within its decentralized economy. By operating without reliance on off-chain components, it aims to provide a robust foundation for the broader decentralized finance landscape. Learn more

DeFi Dollar (USDFI) FAQ
USDFI is the decentralized stablecoin pegged to $1. The governance and utility aspect of the ecosystem has shifted toward $DEFI, which serves as the core utility token. Holders can lock their $DEFI to receive veDEFI (vote-escrowed), allowing them to participate in protocol governance and earn a portion of the generated fees. The STABLE token is associated with older versions of the protocol.
The project serves both roles. It is officially described as a 'Universal Banking Protocol' that provides decentralized financial infrastructure. Simultaneously, USDFI is the name of the decentralized, over-collateralized stablecoin token that powers and operates within that protocol.
USDFI utilizes a market-driven, over-collateralized mechanism. If the token trades below $1, arbitrageurs can redeem it for exactly $1 worth of underlying decentralized collateral. Conversely, if it trades above $1, the protocol encourages users to mint more tokens by lowering interest rates, effectively using decentralized market incentives to maintain the peg.
Users earn yield by depositing USDFI into the Stability Pool to facilitate the liquidation of under-collateralized positions. In return, they receive 'liquidation gains'—which is the collateral at a discount—alongside protocol emissions. The protocol offers multiple pools for different collateral types, such as major decentralized assets, allowing users to choose which assets they prefer to be exposed to during liquidations.
Eligibility is primarily based on user activity within the ecosystem, such as minting USDFI or providing liquidity. Users are encouraged to use official protocol checkers to verify their status securely. Furthermore, users may increase their airdrop allocation through multipliers by committing to lock their tokens for designated periods.
The protocol is a 'friendly fork' of a leading, battle-tested decentralized borrowing platform, which is widely recognized for its robust security. To further ensure the safety of the smart contracts, the project has been audited by high-profile security firms. These audits serve to verify the code's integrity and protect the community from potential exploits or vulnerabilities.
