Which protocols and chains are covered?
Aave v3 on Ethereum, Base, Arbitrum One, OP Mainnet, Polygon PoS, BNB Smart Chain, Avalanche, Linea, Scroll, zkSync Era, Gnosis and Celo, and every Compound v3 market on Ethereum, Base, Arbitrum One, OP Mainnet, Polygon PoS, Linea and Scroll. Each market’s contracts were checked on-chain before we listed them.
Where do the numbers come from?
From the markets themselves, read through public RPC nodes: balances and debts from the pool contracts, rates from the same contracts, and prices from each protocol’s own oracle, the prices it uses to decide liquidations. Nothing comes from a third-party API, and nothing needs a wallet connection or a signature.
What is the health factor?
The collateral, counted at the level where the market liquidates it, divided by the debt. Above 1 the position is safe for now; below 1 anyone can liquidate part of it, selling collateral at a discount to repay the debt. Aave reports it directly; for Compound v3 we work it out from each collateral’s liquidation factor.
Why is a supply rate 0% for some assets?
On Compound v3 only the base asset of a market earns interest: collateral such as WBTC or ETH posted in the USDC market earns nothing. On Aave, assets that few people borrow, WBTC among them, pay close to nothing to suppliers.
