Alchemix (alchemix)

Self-repaying loan protocol. Deposit yield-bearing collateral to borrow synthetic assets (alUSD, alETH) that repay themselves over time via yield.

What it offers

Self-repaying: yield from deposited collateral automatically reduces debt over time
Two Alchemist contracts: alchemistAlUSD (for USD synthetics) and alchemistAlETH (for ETH synthetics)
Max LTV: 50% - can borrow up to half the value of deposited collateral
yieldToken is the yield-bearing version (e.g. yvDAI, aDAI, stETH), not the base token
Approve yieldToken to the appropriate Alchemist contract before depositing
debt is int256 because it can be negative (overpaid/surplus)

On Ethereum, Alchemix is a namespace: its contracts need no import.

function main() {
  // Ethereum's alETH, `0x0100546F2cD4C9D97f798fFC9755E47865FF7Ee6`.
  require(Alchemix.AlETH != 0);
}
