About Interest Protocol

Interest Protocol is a borrow/lend protocol that is highly capital-efficient thanks to its unique combination of fractional reserves and over-collateralization. Depositors may mint USDi, which is a stablecoin pegged 1-1 with USDC that automatically pays interest to holders via rebasing.

How Interest Protocol's TVL is measured

DeFiLlama publishes the exact rules used to aggregate on-chain balances into the headline TVL figure shown on this page. The methodology below is the team's own source-of-truth description.

Counts the tokens locked in the contracts to be used as collateral to borrow or to earn yield. Borrowed coins are not counted towards the TVL, so only the coins actually locked in the contracts are counted. There's multiple reasons behind this but one of the main ones is to avoid inflating the TVL through cycled lending.. For Interest Protocol, TVL is USDC Reserve + Total Deposited Collateral Value Reserve is the amount of USDC held by the USDI contract Balances are found through VaultController.vaultSummaries(1,VaultController.vaultsMinted()) Capped tokens converted 1:1 to underlying Wrapped Uni V3 Positions as implemented report their values to Interest Protocol in USD terms * 1e18, as such, they are currently listed as DAI in the TVL calculation, therefore DAI numbers in the TVL should be treated as Uniswap V3 position collateral value, as DAI is not otherwise listed on IP.

If a contract or vault isn't in this list, its balance does not contribute to the TVL displayed on Mantapex or DeFiLlama.

Optimism Ethereum

Protocol Footprint

Interest Protocol operates on 2 networks (Optimism, Ethereum), keeping its surface area narrower than chain-agnostic peers. Its TVL is heavily concentrated on Optimism, which holds 76% of all assets — other deployments are comparatively small. Price feeds come from a single oracle provider (Chainlink); an outage or manipulation of that feed would propagate into every market the protocol prices. Only one audit report is currently listed; users should weigh that against the protocol's TVL before depositing significant amounts.
