Increases the borrowed amount on an active loan without posting more collateral. The contract reverts if the resulting debt would exceed what the existing collateral supports at the current price. Single transaction in both modes. No approval is involved because funds move out of the pool, not in.

Path Parameters

string

required

Market ID.

Body Parameters

integer

required

On-chain loan ID. A positive integer. Accepted as a JSON number or as a numeric string, so the value Get Loan returns passes straight back.

string

required

Additional amount to borrow, as a decimal string in borrow asset units.

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

Amount borrowed, echoed back. Returned when confirming with txHash.

string

SIGN_TRANSACTION when txHash is omitted.

object

Unsigned transaction, { to, data, value, chainId }, for the borrowMore call. Returned when txHash is omitted.

string

borrowMore. Returned when txHash is omitted.

Borrowing more moves the loan closer to its liquidation threshold. Read the resulting health factor from Get Loan afterwards, and expose it to the borrower before they commit.

Capacity is checked before any transaction is offered. An amount past what the collateral supports is refused with EXCEEDS_MAX_BORROW, and one the pool cannot fund with INSUFFICIENT_LIQUIDITY. That check is skipped when a signedPrice is supplied, because the contract then prices against the signature rather than the stored value. In that case the amount reverts on-chain instead. Compute headroom from Get Max Borrow against the loan’s collateral, less outstanding principal and accrued interest.

Error Codes

Code	HTTP	Cause
`NO_MARKET_ADDRESS`	`400`	The market has no on-chain address recorded
`VALIDATION_ERROR`	`400`	`loanId` is not a positive integer, or `amount` carries more decimal places than the borrow asset supports
`LOAN_NOT_ACTIVE`	`400`	The loan is closed and can no longer be modified
`MARKET_PAUSED`	`400`	The market is paused. Its admin must unpause it
`PRICE_STALE`	`400`	The oracle price is outside the market’s `maxPriceAge`. Push a NAV with Sync Oracle Price, or supply a `signedPrice`
`EXCEEDS_MAX_BORROW`	`400`	The request would take the loan past what its collateral supports. Skipped when a `signedPrice` is supplied
`INSUFFICIENT_LIQUIDITY`	`400`	The pool holds less available liquidity than the request needs
`LOAN_NOT_FOUND`	`404`	No loan with that ID exists on this market
`MARKET_NOT_FOUND`	`404`	No market with this ID on your instance
`MARKET_PENDING_CURATOR`	`409`	The market has no lender of record yet. See Lender of record
`MARKET_STATE_UNAVAILABLE`	`503`	The market could not be read to run a check. Retry shortly
`LOAN_STATE_UNAVAILABLE`	`503`	The loan could not be read from the network. Retry shortly
