About this explorer

The Rails Fluid explorer shows every borrowing position in Fluid's vaults on Ethereum, whether still open or closed, and the full history of each one. It also shows the vaults themselves, with the limits that decide when a position is liquidated.

How it works

Fluid is a lending protocol. A vault is a pool of one collateral token, the asset that backs a loan, that lets people borrow one other token. The debt is what the borrower owes. A position is one borrower's collateral and debt in a vault. It is an NFT, a token its owner holds, so it can move between wallets (account addresses).
The vault's oracle prices the collateral. Some vaults are smart vaults: a side, collateral or debt, is held as shares of a DEX pool, an exchange's liquidity pool. Amounts on that side are then counted in pool shares, not tokens.
Each vault sets three limits, each a share of the collateral's value. The borrow limit is the most a position may borrow. The liquidation threshold is higher: debt above it can be liquidated. Above the maximum liquidation limit, all of the debt could be liquidated.
To liquidate a position, anyone repays part of its debt and receives collateral at a discount. The position's collateral is sold to repay its debt, so the debt falls.

Glossary

Vault: : A vault is a Fluid contract that holds the collateral of its borrowers and lends them one other token. Each vault has its own limits. Docs: Contracts overview, Architecture
Position: : A position is one borrower's collateral and debt in one vault. Each position is an NFT, a token its owner holds, so it can move between wallets. Docs: Get all user vault positions
Oracle: : An oracle is the price source that tells a vault how much the collateral is worth. The vault uses that value to decide how much can be borrowed. Docs: Architecture
Smart vault: : A smart vault holds its collateral, its debt or both as shares of a DEX pool. A DEX is a decentralised exchange, and its pool is the liquidity that traders swap against. Pool shares earn trading fees. Docs: Contracts overview, Smart debt and smart collateral amounts
Borrow limit: : The borrow limit is the most a position may borrow, as a share of its collateral's value. The vault refuses to lend beyond it. Docs: Vault configuration
Liquidation threshold: : The liquidation threshold is the debt-to-collateral share at which liquidation can start. A position with debt above it can be liquidated. Docs: Vault configuration
Liquidation: : A liquidation lets anyone repay part of a position's debt and receive collateral from it at a discount. The collateral is sold to repay the debt. Docs: Fluid liquidation swaps
Maximum liquidation limit: : The maximum liquidation limit is a share of collateral value above the liquidation threshold. A position with debt above it can have all of its debt liquidated. Docs: Vault configuration

Listing

Each row is one position, identified by its NFT id and its current owner.
A row shows the position's collateral and debt in the vault's own tokens, with no dollar value.
A row says whether the position is open or closed and whether it has been liquidated.

Position page

The position page shows the position's current collateral and debt, read from the blockchain. Its timeline lists every deposit, borrow, repayment, withdrawal and liquidation on the position.

Vaults page

The vaults page lists every vault Fluid has created. For each vault, it shows the borrow limit, the liquidation threshold and the maximum liquidation limit. Open the vaults page to see every vault.

You can search by owner wallet or NFT id. The listing filters by Status (open or closed), Debt (the amount borrowed), Vault kind (Standard pairs or Smart vaults), History (Liquidated before or Never liquidated) and Transactions (how many a position has), and sorts by Recent activity, Debt size, Collateral size or Event count.

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

Fluid's deposit-and-earn lending, its DEX trading and its vaults on other blockchains aren't covered here.See what Rails covers on each Ethereum explorer
