THE PROBLEM

/

Onchain credit RUNS

on floating rates.

Most markets reprice constantly without defined maturities. That makes borrowing costs unpredictable, turns yield into a moving target, and forces treasuries to operate without visibility.

Predictable Borrowing

Borrowing costs are defined upfront. No repricing when markets move.

Known Outcomes

Yield is set by maturity. You know what you earn and when.

Flexibility Without Lock-In

Fixed rates don’t mean being stuck. Adjust or exit before maturity.

Treasury-Grade Planning

Match assets and liabilities by maturity. Plan cashflows with confidence.

Yield as a Market Component

Yield becomes something you can allocate and adjust over time.

0% FIXED RATE

Usual Zero Rate Vault is Fira’s first product, built with Usual.

It brings fixed-rate borrowing to a market that already represents over $450M in active liquidity. By depositing bUSD0, users can borrow bUSD0 at a fixed rate of 0%.

This creates predictable, cost-free borrowing for onchain strategies and treasury use cases.

What is Fira?

Fira is a lending and borrowing protocol specialized in facilitating permissionless fixed-rate markets onchain.

Why Fira?

Onchain credit is almost entirely variable-rate, limiting predictability and long-term financial planning in DeFi. Fira introduces fixed-rate, maturity-based borrowing and lending as a native onchain primitive, starting from the proven success of the Usual Stability Loan. By enabling predictable costs of capital and known returns, Fira builds a new layer of fixed-rate credit for DeFi and unlocks scalable, long-horizon financial use cases.
