# Configuration parameters

The initial configuration of Revert Lend supported tokens and parameters was defined by using the risk framework from [Anthias](https://www.anthias.xyz/) described in detail in this document (TODO link).

### Supported Chains and Tokens

Currently Revert Lend is available on `Arbitrum`.

The lend token is `USDC`

The supported collateral tokens are: `USDC, USDC.e, USDT, DAI, WETH, WBTC, ARB, wstETH`.

### Collateral factors

To decide the collateral factor of a LP position, the lower collateral factor of the two tokens is applied.
