InfiniFi USD wallet

What is InfiniFi USD (IUSD)?

iUSD is the dollar-pegged deposit token of infiniFi, a protocol on Ethereum that takes in stablecoin deposits and routes them into a mix of liquid and locked DeFi positions. When a user deposits into the protocol, they receive iUSD one-for-one as the claim on that deposit; redeeming iUSD returns the underlying stablecoin, subject to the protocol's reserve mechanics. In the wallet, iUSD behaves like a plain ERC-20: the balance does not rebase, does not grow on its own and only changes when you send, receive, deposit or redeem.

That matters because infiniFi has more than one token, and they are easy to confuse. Plain iUSD is the base receipt. Staking it inside the protocol issues siUSD, a vault-share token whose value relative to iUSD moves with the protocol's accounting, and locking it issues liUSD, which stays locked until the holder triggers an unwinding period and waits for it to finish. Only plain iUSD is directly redeemable. If the balance you see in the app is not moving, that is iUSD doing exactly what it is designed to do; the accrual lives in the staked and locked versions, not here.

Two practical points for holding it. Every transfer or redemption is an Ethereum transaction, so you need a little ETH in the same address to pay gas. And IUSD is a ticker shared by several unrelated projects, on other chains and on Ethereum itself, so a token with the same letters is not automatically this asset.

Because iUSD just sits in the address until you decide to redeem or stake it, there is nothing for a wallet to do in between. The Tangem app reads the balance straight from Ethereum, and the card only comes out of the drawer when you actually sign something, which for a parked stablecoin position may be rarely.
