infiniFi Protocol Overview

infiniFi is a protocol designed to amplify returns on existing DeFi platforms like Pendle, Ethena, and AAVE, which we refer to as farms. It actively holds value, enabling users to deposit and redeem cryptocurrencies, participate in governance, and earn interest. It achieves increased returns using fractional reserve banking principles.

​
Farms

We categorize farms based on their liquidity and the time delay required to access the principal deposited value:
Farm TypeDescriptionExample
Liquid farmsInstant access to principalAAVE, ERC4626-like farms
Maturity farmsDelayed access to principalPendle, Ethena (ERC7540-like)
Protocol farmsInternal fund movement, no yieldProtocol-specific
Illiquid farms are further categorized into buckets (1 week, 2 weeks, …, 13 weeks) based on the time needed to retrieve the principal value.

​
Tokens

iUSD

Receipt Token - Obtained by depositing USDC. No interest, but can be redeemed or locked.

siUSD

Staked Token - Obtained by staking iUSD. Provides liquid returns.

liUSD-xw

Locked Position Token - Obtained by locking iUSD. Grants illiquid returns + governance.

​
Asset Allocation

liUSD holders constitute infiniFi governance. Governance members vote on capital distribution between the farms. Voting power is determined by:
  • The locked iUSD amount
  • The unwinding period (longer = more power)
liUSD holders cannot vote on farms outside their bucket range. For example, a liUSD-1w holder cannot vote on Pendle farms but can vote on Ethena.

​
Fractional Reserve Principle

InfiniFi applies fractional reserve banking to maximize returns: 
Example with 1,000 USDC liquid + 500 USDC illiquid deposits:

Standard approach:
- 1,000 USDC → liquid farms
- 500 USDC → illiquid farms

InfiniFi approach (20% fractional deployment):
- 800 USDC → liquid farms (-20%)
- 700 USDC → illiquid farms (+40%)
This strategy enhances yields for both deposit types while maintaining liquidity.
