Category: fixed-rate lending protocol / utilization-priced maturity-pool credit market / shared-liquidity bridge between variable and fixed rates
Summary: Exactly Protocol is best understood as a fixed-rate credit design built around utilization-priced maturity pools, not around tokenized term claims or auction-cleared repo series. Its official materials repeatedly emphasize one Variable Rate Pool per asset, multiple Fixed Rate Pools by maturity, and direct fixed-rate discovery from supply and demand in each maturity pool. The reusable mechanism insight is that Exactly tries to solve fixed-income fragmentation by warehousing liquidity in a shared floating-rate pool that temporarily funds fixed-term demand, which shifts the real control surface toward utilization-curve calibration, reserve policy, risk factors, and governance-admin powers.
What it does:
Lets users lend and borrow crypto assets at both variable and fixed rates inside one protocol
Uses one Variable Rate Pool per asset to provide immediate liquidity to multiple Fixed Rate Pools with different maturities
Prices fixed-rate loans from the utilization of each maturity pool rather than from maturity-token prices or a bespoke AMM for zero-coupon claims
Issues ERC-4626 exaVoucher deposit claims for variable-rate suppliers and allows those vouchers to be used as collateral
Uses dynamic close-factor liquidation logic, liquidity reserves, and risk-adjust factors to manage solvency and withdrawals
Key claims:
The official site describes Exactly as a decentralized, non-custodial, open-source protocol providing an autonomous fixed and variable interest rate market
The white paper says the protocol discovers fixed rates directly from the supply and demand of credit in each Fixed Rate Pool for each asset and maturity term
The white paper and math paper explicitly contrast Exactly with Notional-, Yield-, Element-, and Pendle-like maturity-token systems, arguing that those approaches fragment liquidity and make fixed-rate discovery depend indirectly on token slippage and special-purpose AMMs
The math paper says the Variable Rate Pool exists to immediately satisfy fixed-rate credit demand until fixed-term deposits arrive, which makes it the protocol’s answer to fragmented liquidity across multiple maturities
The papers model fixed-rate borrowing with a continuous utilization-based rate function and describe normal, leveraged, and unreachable regimes, making curve-shape calibration a central governance lever
The docs say the TimelockController is the administrator, with a 24-hour timelock and a 3-of-6 multisig executor; the Protocol Owner multisig controls upgrades, parameter changes, and pause powers
The docs and query interface say a Risk Management Committee multisig can update listed assets, rate models, risk-adjust factors, liquidator incentives, and liquidity reserves, while Hypernative can trigger emergency pauses but not unpause the protocol
Whitepaper: Exactly maintains official white and math papers in its docs rather than a standalone PDF surfaced in this pass. The strongest current source snapshot is ../whitepapers/exactly-protocol-primary-sources-2026-05-08.md.
