Traditional banking
- Deposits are short-term, loans are long-term.
- The bank keeps most of the yield from that mismatch.
- Depositors can't choose their own liquidity or risk.
On-chain fractional reserve banking. Deposit stablecoins, then pick your trade-off: stay liquid, or lock longer and earn more. Here's how the protocol works, who backs it and how it's secured.
Banks take short-term deposits and make long-term loans. That mismatch earns the yield, but it also creates bank-run risk, and depositors never get a say in it. InfiniFi hands that choice back to depositors.
Every deposit becomes iUSD. From there you decide how much liquidity to give up in exchange for yield.
Minted 1:1 when you deposit USDC or USDT through the Gateway. Pegged to $1. On its own it earns nothing; you redeem it, stake it, or lock it.
An ERC-4626 vault share. It earns yield from the protocol's strategies and stays liquid, so you can convert back to iUSD at any time.
Lock iUSD for 1 to 13 weeks (liUSD-1w … liUSD-13w). Lockers earn the highest yield and governance power, and act as first-loss capital.
If a strategy loses money, losses flow through the layers in a fixed order. Taking more risk earns more yield.
Deposits are allocated to approved "farms" in two buckets.
Key milestones so far.
Two rounds totaling more than $6M, both led by Electric Capital.
The protocol was reviewed before launch and is still reviewed with each upgrade. Admin power sits behind a multisig and timelocks.
Main code review in Mar–Apr 2025; report published Apr 1, 2025. Ongoing reviews cover later upgrades.
Formal verification and security assessment, Mar 21 – May 20, 2025; report published Jun 4, 2025.
Public audit competition in Apr 2025, plus an active bug bounty program on Cantina.
iUSD is the $1 receipt you get for depositing USDC or USDT. siUSD is staked iUSD: it earns yield and stays liquid. liUSD is iUSD locked for 1–13 weeks: it earns the most, carries governance power and absorbs losses first.
Electric Capital led both the $3M pre-seed (Feb 2025) and the $3M+ seed (announced Sep 2026). Other participants include New Form Capital, Generative Ventures, Fasanara Capital, 2Square, Fourth Revolution Capital, The Rollup, Kraynos Capital and angel investors such as Sam Kazemian and DeFi Dad.
