InfiniFi USD
iusdWhat is InfiniFi USD?
iUSD is the receipt-token leg of infiniFi, a fractional-reserve DeFi protocol built around stablecoin deposits and duration-matched yield strategies. The token represents deposited value within the protocol rather than a direct claim on dollars held in a bank or a guaranteed one-dollar stablecoin. Official documentation distinguishes iUSD from siUSD (staked, liquid yield exposure) and liUSD-xw (locked position tokens).
What problem does InfiniFi USD solve?
infiniFi targets the duration and liquidity mismatch found in yield markets: fully liquid deposits generally access lower returns, while higher-return strategies may be less liquid. Its documented design lets depositors choose between keeping iUSD liquid, staking for liquid returns, or accepting an exit timer and first-loss exposure through locked positions. These are protocol design goals, not a promise that yield or immediate redemption is guaranteed.
How does InfiniFi USD work?
Users deposit USDC or another supported stablecoin through the infiniFi Gateway and mint iUSD. The protocol allocates capital across liquid and maturity-based farms, including integrations documented in its code and product materials. Staking iUSD produces siUSD exposure to liquid returns; locking produces a duration-specific liUSD-xw position with higher target yield and slower exit. Redemptions use a queue when liquid assets are insufficient. The public code describes Core-controlled role permissions, guardian pause controls, governor-controlled core replacement and emergency calls; Etherscan identifies the Ethereum Gateway as a verified transparent upgradeable proxy. These administrative and upgrade controls mean token holders should not treat iUSD as an immutable governance instrument or as a guaranteed claim independent of protocol state.
Key facts
- Canonical identity is infiniFi’s iUSD ERC-20 receipt token, not a conventional fiat-backed stablecoin; the project FAQ explicitly calls it a deposit receipt and says iUSD is not a stablecoin.
- The documented Ethereum Mainnet iUSD contract is 0x48f9e38f3070AD8945DFEae3FA70987722E3D89c; the Gateway V1 is 0x3f04b65Ddbd87f9CE0A2e7Eb24d80e7fb87625b5.
- The official product flow is deposit stablecoins, mint iUSD, then withdraw, stake into siUSD, or lock into duration-specific liUSD-xw positions.
- iUSD is described as non-yield-bearing by itself; siUSD is the staked liquid-yield form, while liUSD-xw positions carry higher target yield and slower exits.
- The FAQ describes a first-in-first-out redemption queue during temporary illiquidity and says secondary-market sales may involve depeg or slippage.
- The public contract registry lists a Core, team multisig, keepers, manual rebalancer and short/long timelocks; this is operational infrastructure, not evidence of token-holder legal ownership or revenue rights.
- The Ethereum Gateway is a verified TransparentUpgradeableProxy on Etherscan, so implementation changes are an explicit administrative risk to monitor.
- The public repository documents role-based governor and guardian controls, farm allocation voting, liquid/maturity farms and emergency actions; it does not establish a legal claim to protocol profits for iUSD holders.

Frequently asked questions
Is iUSD a US-dollar stablecoin?
No. infiniFi’s FAQ explicitly describes iUSD as an ERC-20 deposit receipt and says iUSD is not a stablecoin. Its market value can move away from one dollar when redemption liquidity or secondary-market liquidity is constrained.
What rights does an iUSD holder have?
The documented right is a protocol redemption process for deposited value, subject to available liquidity and queue mechanics. iUSD does not, on the cited evidence, confer equity, a guaranteed fixed yield, legal ownership of underlying assets, or a contractual share of protocol profits.
How can iUSD earn yield?
iUSD itself is described as non-yield-bearing. Users may stake it to receive siUSD for liquid yield exposure or lock it into liUSD-xw positions for higher target yield with an exit timer and greater loss exposure.
What happens if many users withdraw at once?
The protocol says redemptions normally use a queue and may become temporarily delayed when capital is invested in illiquid strategies. Users can wait for assets to mature or sell in a secondary pool, potentially at a depeg or with slippage.
What is the verified Ethereum iUSD contract?
The official contract registry lists 0x48f9e38f3070AD8945DFEae3FA70987722E3D89c as iUSD on Ethereum Mainnet. Always verify the network and address before interacting.
Can administrators change or pause the system?
Public materials document governor and guardian roles, pause controls, emergency actions, a team multisig and timelocks. Etherscan identifies the main Gateway as a TransparentUpgradeableProxy, so users should monitor role assignments, implementation changes and emergency transactions.
