Notes
- Deposited assets serve dual purpose as lending collateral AND DEX liquidity
- No interest rate mode selection — all rates are algorithmically determined
- Same contract address on Ethereum and Arbitrum
- Built by the Instadapp team
- All deposit/repay operations require ERC-20 approval (to the fToken or Vault)
Its names in a program
On Ethereum,Fluid is a namespace: its contracts need no import.
Deployments
ABI
Where a line says what an address it returns is, a program that calls the function through its namespace calls that contract’s methods on the result directly:<Namespace>.<Contract>.<function>(...).<method>(...). A token’s methods are the ERC-20
functions, and its writes are SafeERC20.
FluidLendingABI
import FluidLendingABI from "./protocols/fluid/FluidLendingABI.json";
deposit(uint256 assets, address receiver) returns (uint256 shares)withdraw(uint256 assets, address receiver, address owner) returns (uint256 shares)redeem(uint256 shares, address receiver, address owner) returns (uint256 assets)asset() view returns (address): the address is a token
FluidVaultABI
import FluidVaultABI from "./protocols/fluid/FluidVaultABI.json";
operate(uint256 nftId, int256 newCol, int256 newDebt, address to) payable returns (uint256, int256, int256)
