Is Fira Safe?
Risk Grade: C+ (39/100)
Fira is rated as elevated risk — multiple novel mechanisms and notable interaction risks.
Limited Data Available
This protocol has limited public documentation. Our analysis may not fully capture all risk dimensions.
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.

Key Risks for Fira Users
Almost all TVL is in a single asset (bUSD0) — if this token loses value, the entire protocol is at risk
Zero-rate borrowing encourages leveraged positions that could amplify losses during market stress
Only 14 months of operating history since December 2024 launch — untested in a major DeFi downturn
Entirely dependent on Usual protocol health — if USD0 has problems, Fira has problems
Limited public documentation makes independent risk assessment difficult
Top Risk Factors
- •Fira's $434M TVL is almost entirely concentrated in bUSD0 (Usual's bond token) — a single-asset dependency where any bUSD0 devaluation or Usual protocol failure would wipe out the vast majority of collateral value.
- •As a zero-rate lending primitive, Fira enables capital-efficient borrowing against bUSD0 without interest charges, creating leverage incentives that could amplify losses during a USD0 stress event.
- •Fira launched in December 2024 with limited production history — the protocol has only ~14 months of operation under varying market conditions and has not been tested during a major DeFi stress event.
