Liquity V1: claim collateral surplus

Liquity V1 can credit ETH to your address after a full redemption or certain liquidations. That surplus stays in a separate pool until claimed. It is separate from an open Trove.

Contracts and a public claim simulation were checked on 2026-11-02. Connected frontend steps still need browser review. DeFi Checkup never connects a wallet or asks for signatures.

Who is eligible

The check reads getCollateral(address) and getETH() on Ethereum CollSurplusPool, 0x3D32e8b97Ed5881324241Cf03b2DA5E2EBcE5521. A positive credit with sufficient pool backing is reported as ETH. An underbacked credit is shown without a recoverable amount or dollar value. Other Liquity balances, smart wallet ownership and Liquity V2 positions are outside this check.

How to get it out

  1. Start at Liquity’s official V1 frontend list. Liquity does not operate its own frontend; the listed interfaces are independent operators.
  2. Use a V1 interface with the address credited by the surplus pool. Review the surplus claim there. The V1 borrowing FAQ explains the collateral surplus after redemption.
  3. The contract route is claimCollateral() on BorrowerOperations, 0x24179CD81c9e782A4096035f7eC97fB8B783e007. Users cannot call the pool’s restricted claimColl function directly. Do not open a new Trove just to recover this credit.
  4. Compare the full contract address and ETH amount before confirming on the external interface. If a smart wallet was credited, its authorized owner must use that wallet’s execution route.

What it costs

One Ethereum claim transaction needs ETH for gas. The scanner uses an estimate of 100,000 gas, not a measured transaction cost. A public eth_call succeeded, but that is a simulation rather than a mined claim or a guarantee of future execution. Compare the current wallet fee with the surplus. A tiny credit can cost more to claim than it is worth.

Deadline

No claim deadline was found in the verified V1 contracts. Pool backing and the claimant’s ability to receive ETH still matter. The check does not recover liquidation losses or repaid debt.

Check your address

Scan your address without connecting a wallet or signing. Review the coverage limits and any incomplete warning before relying on a result.

FAQ

Does this include the ETH in an active Trove?

No. This check covers only collateral already credited to CollSurplusPool.

Can another address claim my surplus?

BorrowerOperations claims for its caller. Knowing an address does not give control of its credit. Use the address credited by the pool, including a smart wallet if that was the borrower.

Is this a free claim?

The credit itself is already recorded, but claiming still costs Ethereum gas. The scanner’s fee is an estimate; compare it with the surplus and the current wallet estimate before proceeding.
