Signature verification

The api expects a EIP712 signature constructed with the following typed data:

{
  EIP712Domain: [
    {
      name: 'name', // rysk
      type: 'string',
    },
    {
      name: 'version', // "0.0.0"
      type: 'string',
    },
    {
      name: 'chainId', // 168587773 - BLAST testnet | 
      type: 'uint256',
    },
    {
      name: 'verifyingContract',  // <OrderDispatchAddress> - BLAST testnet |
      type: 'address',
    },
  ],
  Withdraw: [
		{
			name: "account", // address of the account withdrawing
			type: "address",
		},
		{
			name: "subAccountId", // subAccountId of the subaccount to withdraw from
			type: "uint8",
		},
		{
			name: "asset", // address of the asset in the margin account to withdraw
			type: "address",
		},
		{
			name: "quantity", // quantity to withdraw in e18 format
			type: "uint128",
		},
		{
			name: "nonce", // unique nonce for the transaction, nonces are tracked globally across all actions and cannot be repeated
			type: "uint64",
		},
	],
}

Example request:

{
  "account": "0x1234",                                    // Account address
  "subAccountId": 0,                                      // Subaccount id
  "asset": "0x4300000000000000000000000000000000000003",  // Address of the asset to withdraw (USDB)
  "quantity": "10000000000000000",                        // Quantity of the order in e18 decimals
  "nonce": 1718718131305466,                              // Unique nonce for the transaction, nonces are tracked globally across all actions and cannot be repeated 
  "signature": "0x1234..."                                // Signature for verifying the order
}
