Struct Eip712Domain 

pub struct Eip712Domain<'a> {
    pub name: &'a str,
    pub version: &'a str,
    pub chain_id: u64,
    pub verifying_contract: &'a [u8; 20],
}

EIP-712 domain separator parameters.

Use Eip712Domain::separator to compute the 32-byte domain separator hash.

use chains_sdk::ethereum::Eip712Domain;

let contract_addr = [0xCC_u8; 20];
let domain = Eip712Domain {
    name: "MyDapp",
    version: "1",
    chain_id: 1,
    verifying_contract: &contract_addr,
};
let sep = domain.separator();

Fields

name: &'a str

Human-readable name of the signing domain (e.g., “Uniswap”).

version: &'a str

Current major version of the signing domain (e.g., “1”).

chain_id: u64

EIP-155 chain ID (1 = mainnet, 5 = goerli, etc.).

verifying_contract: &'a [u8; 20]

Address of the contract that will verify the signature (20 bytes).

Implementations

impl<'a> Eip712Domain<'a>

pub fn type_hash() -> [u8; 32]

The EIP-712 domain type hash: keccak256("EIP712Domain(string name,string version,uint256 chainId,address verifyingContract)")

pub fn separator(&self) -> [u8; 32]

Compute the 32-byte domain separator.

keccak256(abi.encode(TYPE_HASH, keccak256(name), keccak256(version), chainId, verifyingContract))
