Safety has never been a short-term goal; it is a fundamental attribute that any system should always maintain.

A leading DeFi protocol on Ethereum has officially launched the Fira UZR zero-interest lending module, simultaneously expanding its bug bounty program coverage—this fully demonstrates the key position of this lending system within the entire ecosystem.

UZR is essentially a fixed-rate lending scheme. Users can use bUSD0 as collateral to borrow USD0 at a fixed annualized interest rate of 0.1%, plus a 0.1% annual service fee. This scheme has migrated liquidity from the previous Euler-based system (USL) directly to the protocol’s self-built infrastructure, making the entire architecture more independent and efficient.

The new round of bug bounty focuses on potential risks in the Fira UZR smart contracts and their supporting modules—any vulnerabilities that could threaten fund security or compromise the protocol’s integrity are within scope. Only contracts deployed on the Ethereum mainnet qualify for bounties.

Smart contracts included in the audit scope encompass: the UZR lending core contract (Fira UZR Vault), UZR oracle adapter module, restricted-access collateral vault (bUSD0 collateral vault), USD0/bUSD0 oracle, and its backup price feed mechanism. From lending logic to price input, each component has corresponding review standards.
