The 0x-prefixed address of the EVM account.
Pattern:
^0x[0-9a-fA-F]{40}$Body

Example:
{
"name": "Permit2",
"chainId": 1,
"verifyingContract": "0x000000000022D473030F116dDEE9F6B43aC78BA3"
}
A mapping of struct names to an array of type objects (name + type).
Each key corresponds to a type name (e.g., "EIP712Domain", "PermitTransferFrom").
Example:
{
"EIP712Domain": [
{ "name": "name", "type": "string" },
{ "name": "chainId", "type": "uint256" },
{
"name": "verifyingContract",
"type": "address"
}
],
"PermitTransferFrom": [
{
"name": "permitted",
"type": "TokenPermissions"
},
{ "name": "spender", "type": "address" },
{ "name": "nonce", "type": "uint256" },
{ "name": "deadline", "type": "uint256" }
],
"TokenPermissions": [
{ "name": "token", "type": "address" },
{ "name": "amount", "type": "uint256" }
]
}
The primary type of the message. This is the name of the struct in the types object that is the root of the message.
Example:
"PermitTransferFrom"
The message to sign. The structure of this message must match the primaryType struct in the types object.
Example:
{
"permitted": {
"token": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
"amount": "1000000"
},
"spender": "0x1111111254EEB25477B68fb85Ed929f73A960582",
"nonce": "0",
"deadline": "1716239020"
}
Response
Successfully signed typed data.
The signature of the typed data, as a 0x-prefixed hex string.
Example:
"0x1b0c9cf8cd4554c6c6d9e7311e88f1be075d7f25b418a044f4bf2c0a42a93e212ad0a8b54de9e0b5f7e3812de3f2c6cc79aa8c3e1c02e7ad14b4a8f42012c2c01b"
