About this explorer

The Rails Compound V3 explorer shows the accounts in Compound V3's five Base markets, whether still open or closed, and the full history of each one. It also shows the markets themselves, with their interest rates and reserves.

How it works

Compound V3 is a lending protocol. People supply crypto to earn interest, or deposit collateral and borrow against it. On this page an account is the balances one wallet (an address that holds crypto) has in one market.
Base has five markets, with USDC, WETH, USDS, AERO and USDbC as their base assets. Each market is a smart contract called a Comet, with one base asset. Suppliers of the base asset earn interest, and borrowers draw the base asset alone. The Base markets are separate from the Ethereum markets of the same names.
The interest rate on supplying and on borrowing rises as more of the base asset is lent out. Each market sets its own rates.
When an account's debt passes what its collateral covers, anyone can trigger its liquidation, and the market takes over its debt and collateral. Compound calls this step absorbing. The market pays the borrower the collateral's value minus a penalty, from its reserves.

Glossary

Comet: : A Comet is the smart contract of one Compound V3 market. It holds one base asset and a list of collateral assets, and shares nothing with any other Comet. Docs: Introduction, Collateral and borrowing
Base asset: : The base asset is the one token a Comet lends out and borrows. A wallet's balance in it is positive if the wallet has supplied and negative if it owes. Docs: Introduction, Supply
Collateral: : Collateral is a token a wallet deposits to back its borrowing. Each collateral asset has a factor, the percentage of its value that counts toward borrowing. The collateral earns no interest. Docs: Collateral and borrowing
Interest rate: : Supplying the base asset earns the supply rate and borrowing it costs the borrow rate. Both rise as more of the base asset is lent out, and interest builds up every second. Docs: Interest rates
Liquidation: : A wallet becomes liquidatable when its debt exceeds what its collateral covers. That is measured with the liquidation factors, the percentages of each collateral asset's value that count toward staying safe. They are higher than the borrowing factors, which limit how much a wallet can borrow. Docs: Liquidatable accounts
Absorb: : Absorbing is the liquidation step. Any address can absorb a liquidatable account, and the Comet then takes over the account's debt and collateral. The borrower is paid the collateral's value minus a penalty, in the base asset. Docs: Absorb
Reserves: : Reserves are a balance of the base or collateral asset that a market's protocol holds to protect users from bad debt. A liquidation adds the seized collateral to the protocol's holdings. Docs: Reserves

Listing

Each row shows one account: the wallet, its market, what it supplied or borrowed and its collateral.
Every figure is read from the market's contract at the block the row names, with dollar values from the prices the market uses for liquidation.
The listing shows open accounts by default. Searching for a wallet shows its accounts of every status.

You can search by wallet address. The listing filters by Status (open, closed or liquidated), Market, Debt and Collateral by size in US dollars, History (liquidated before) and Transactions, and sorts by recent activity, debt or collateral.

Position page

The top card shows the account's balances in one market, read from its contract.
The wallet's own page holds one card for each market the wallet has used, and the timeline lists its events, newest first.

Market view

The market view shows each Base market with its base asset, collateral assets, interest rates and reserves. Open the market view to see them.

Tap the (i) beside any figure to see where it comes from. Inside, the ? explains that kind of event in general.
