## 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 Type | Description | Example |
| ------------------ | -------------------------------- | ----------------------------- |
| **Liquid farms** | Instant access to principal | AAVE, ERC4626-like farms |
| **Maturity farms** | Delayed access to principal | Pendle, Ethena (ERC7540-like) |
| **Protocol farms** | Internal fund movement, no yield | Protocol-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
**Receipt Token** - Obtained by depositing USDC. No interest, but can be redeemed or locked.
**Staked Token** - Obtained by staking iUSD. Provides liquid returns.
**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.
