​Request Parameters

Parameter	Type	Required	Description
tx	object	Yes	Burn LP transaction object. See Signing section for details on the transaction fields.
tx.sender	string	Yes	Hex string representing the subaccount’s 32 bytes (address + subaccount name) of the tx sender.
tx.productId	number	Yes	A product ID to mint LP for.
tx.amount	string	Yes	Combined amount of base + quote to burn multiplied by 1e18, sent as a string.
tx.nonce	string	Yes	This is an incrementing nonce, can be obtained using the Nonces query.
signature	string	Yes	Signed transaction. See Signing section for more details.

​Signing

See more details and examples in our signing page.

The solidity typed data struct that needs to be signed is:

struct BurnLp {
    bytes32 sender;
    uint32 productId;
    uint128 amount;
    uint64 nonce;
}

sender: a bytes32 sent as a hex string; includes the address and the subaccount identifier.

productId: a uint32 that specifies the product you’d like to burn LPs for; can be either a spot or a perp product.

amount: combined amount of base + quote to burn, sent as a string. This must be positive and must be specified with 18 decimals.

nonce: the tx_nonce. This is an incrementing nonce, can be obtained using the Nonces query.

Note: for signing you should always use the data type specified in the solidity struct which might be different from the type sent in the request e.g: nonce should be an uint64 for Signing but should be sent as a string in the final payload.
