# Aave

The Aave Protocol is decentralised non-custodial liquidity protocol where users can participate as suppliers, borrowers or liquidators. Suppliers provide liquidity to a market and can earn interest on the crypto assets provided, while borrowers are able to borrow in an overcollateralized fashion. Borrowers can also engage in one-block borrow transactions (”flash loans”), which do not require overcollateralization.

The Uliquid V1 protocol currently supports Liquidation and Leverage on the following Aave Versions:

| Protocol Version | Supported Chains                       |
| ---------------- | -------------------------------------- |
| Aave Version 2   | Ethereum, Polygon,                     |
| Aave Version 3   | Polygon, Arbitrum, Avalanche, Optimism |
