Overview
Centuari’s Fixed Rate Lending is the core product that enables predictable yields for lenders and predictable costs for borrowers. All transactions are gasless and cross-chain by default.Key Innovation: Unlike variable-rate protocols where rates change constantly, Centuari locks in your rate at the moment of execution. Your 8% APY stays 8% APY, period.

How Matching Works
Centuari uses a hybrid order book model. Orders are matched using price-time priority:- Best rates match first
- Among equal rates, earlier orders match first
- Partial fills are supported
Off-chain Orders, On-chain Settlement: Orders are stored and matched off-chain for speed and zero gas costs. Only settlement happens on Arbitrum for security.
Supported Assets
Lending/Borrowing
Collateral
Multiple crypto and RWA collateral types are supported with varying LTV ratios. See all collateral types and parameters.Protocol Parameters
Predetermined Maturity Dates
Centuari uses a rolling system of predetermined maturity dates:- All positions mature on the 1st of the month
- A maximum of 3 maturity dates are active at any time
- When the nearest maturity passes, a new one opens (auto-rotate)
- Example: If Jan 1, Feb 1, Mar 1 are active, after Jan 1 passes, Apr 1 opens
