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.

Overview
Banking's duration gap, rebuilt on-chain
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.
InfiniFi
- Depositors choose: stay liquid, or lock for 1–13 weeks.
- Capital is split between liquid strategies and longer-dated yield (e.g. Pendle, Ethena).
- Lockers take first loss in exchange for higher yield and governance power.
How it works
One deposit, three positions
Every deposit becomes iUSD. From there you decide how much liquidity to give up in exchange for yield.
Receipt token
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.

Staked iUSD
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.

Locked iUSD
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.

Who absorbs losses first
If a strategy loses money, losses flow through the layers in a fixed order. Taking more risk earns more yield.

Where the yield comes from
Deposits are allocated to approved "farms" in two buckets.
- Liquid farms: principal can be withdrawn instantly and is pulled automatically when users redeem.
- Maturity farms: principal returns after a rolling notice period of 7, 28 or 56 days, in exchange for higher yield.
- Redemptions: instant up to liquid capacity; any excess joins a first-in, first-out queue.

FAQ
Common questions
Where can I find INFI token details?
What's the difference between iUSD, siUSD and liUSD?
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.
