InfiniFi: Taking Onchain Banking and Fixed Yield to Neobanks

InfiniFi rebuilds what a bank does, borrow short and lend long, entirely onchain. Rob, the co-founder, told Julian Stafford that banks lend deposits out for months or years and pay depositors very little, keeping the spread. InfiniFi passes most of that spread to depositors instead. He said the gap between institutional yields and what DeFi users earn comes down to duration. Institutional-grade yields usually require locking money for 30, 60 or 90 days, while most retail DeFi users want their funds available at any moment.

The product has two sides. A user deposits USDC and mints siUSD, the liquid token. After an automated rebalancer runs, about 75% of the money is spread across a ladder of one, four and eight week assets and the rest stays as reserve. Users who accept a lockup receive liUSD, choose a redemption period from one to 13 weeks, and earn more. Rob quoted about 6.5% on the liquid side and roughly 6.7% to 9.5% for locks when the episode was recorded. The locked tranche is junior and takes losses first, which Rob said has never been needed. Yield comes from maturity transformation, not leverage or token emissions. He said InfiniFi has always offered same-block liquidity, including through a drawdown of about $60 million in 48 hours.

Security came up early. Rob said there are no centralized minting keys to steal. The offchain rebalancer can only send funds to whitelisted farms, and adding a farm takes a timelock. Operations sit behind a multisig, every release gets at least one audit, and users can buy cover on Nexus Mutual.

InfiniFi Prime is the new product. Many traditional finance firms want onchain returns but not smart contract risk or unfamiliar curators. Prime creates a segregated instance of InfiniFi where a known, regulated asset manager runs the portfolio through tokenized assets, and the neobank takes the senior tranche. The headline is a 6.5% fixed rate on stablecoin deposits. InfiniFi Core can hold the junior tranche and act as a liquidity backstop. Rob chose neobanks and fintech apps because he believes retail will arrive through intermediaries, as with the Robinhood and Coinbase earn programs. He called the earn account the real battleground: a neobank can pay users less than 6.5%, keep a margin and still beat competitors paying around 5%.

On growth, InfiniFi announced a token launch for Q4. It has been live for about 15 months, launched in June 2025, and is running a capital-based points program in a final sprint before the token. Rob's one-year goals are $500M to $1B in TVL and three to five Prime instances, with large consumer finance names as targets.
