Fira

Fira receives a C+ risk grade (39/100) from Hindenrank, where lower scores indicate lower risk. Fira offers an innovative zero-rate lending primitive within the Usual ecosystem, but extreme single-asset concentration in bUSD0 and leverage-friendly mechanics create elevated risk that outweighs the capital efficiency benefits. Fira is a fixed-rate lending protocol within the Usual ecosystem that enables zero-rate borrowing of USD0 stablecoins against bUSD0 (bond USD0) collateral. With $434M in TVL concentrated almost entirely in bUSD0, it serves as Usual's protocol-owned credit primitive, keeping lending revenue internal to the ecosystem rather than relying on external lending partners.

The key risks identified for Fira are: (1) Almost all TVL is in a single asset (bUSD0) — if this token loses value, the entire protocol is at risk (2) Zero-rate borrowing encourages leveraged positions that could amplify losses during market stress (3) Only 14 months of operating history since December 2024 launch — untested in a major DeFi downturn (4) Entirely dependent on Usual protocol health — if USD0 has problems, Fira has problems (5) Limited public documentation makes independent risk assessment difficult
