Removes collateral from a loan while leaving it open. The contract reverts if the withdrawal would push the health factor below 1.0, so a loan can only shed collateral it does not need. Single transaction in both modes.

Path Parameters

string

required

Market ID.

Body Parameters

integer

required

On-chain loan ID. Must be a positive integer sent as a JSON number.

string

required

Security tokens to release, as a decimal string. Parsed at the collateral token’s decimals.

object

EIP-712 signed price from Sign Price. Omit to price against the stored oracle value.

Show child attributes

string

Price in base units.

integer

Signing timestamp.

integer

Signature expiry.

string

EIP-712 signature.

string

Hash of the transaction you broadcast for this operation. Send it to confirm the transaction and record the result. Omit it to receive the calldata.

Response Fields

object

Show child attributes

string

Transaction hash. Returned when confirming with txHash.

integer

Loan ID, echoed back. Returned when confirming with txHash.

string

Collateral released, echoed back. Returned when confirming with txHash.

string

SIGN_TRANSACTION when txHash is omitted.

object

{ to, data } for the withdrawCollateral call. Returned when txHash is omitted.

This endpoint performs no preflight check. A withdrawal that would breach the health factor, exceed the posted collateral, or target an inactive loan reverts on-chain. Compute the safe amount from the loan’s current state before submitting.

Where the released tokens end up depends on the market mode. FREEZE markets unfreeze them in place, so the borrower’s balance does not change but the tokens become transferable again. CUSTODY markets transfer them out of the adapter back to the borrower.
