Request Parameters

Parameter
Type
Required
Description

tx

object

Yes

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

signature

string

Yes

Signing

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.

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.
