Struct OrderDomain 

pub struct OrderDomain {
    pub name: &'static str,
    pub version: &'static str,
    pub chain_id: u64,
    pub verifying_contract: Address,
}

The EIP-712 domain for CoW Protocol orders.

Mirrors TypedDataDomain from the TypeScript SDK.

Fields

name: &'static str

Protocol name ("Gnosis Protocol").

version: &'static str

Protocol version ("v2").

chain_id: u64

Chain ID where orders are settled.

verifying_contract: Address

GPv2Settlement contract address (the EIP-712 verifying contract).

Implementations

impl OrderDomain

pub const fn for_chain(chain_id: u64) -> OrderDomain

Construct the standard CoW Protocol EIP-712 domain for chain_id.

Uses the canonical SETTLEMENT_CONTRACT address as the verifying contract.

Arguments

• chain_id - The EVM chain ID where orders will be settled.

Returns

An OrderDomain configured for the given chain.

pub fn domain_separator(&self) -> FixedBytes<32>

Compute the EIP-712 domain separator for this domain.

When all fields are at their default values ("Gnosis Protocol", "v2", canonical settlement contract), this is equivalent to crate::domain_separator. When any field has been overridden via the with_* builder methods, the separator is computed from the custom values.

use cow_signing::types::OrderDomain;

let domain = OrderDomain::for_chain(1);
let sep = domain.domain_separator();
assert_ne!(sep, alloy_primitives::B256::ZERO);

pub const fn with_name(self, name: &'static str) -> OrderDomain

Override the protocol name used in the EIP-712 domain separator.

The default is "Gnosis Protocol". Use this when computing domain separators for forks or alternative deployments.

Arguments

• name - The protocol name string.

Returns

self with the updated name.

pub const fn with_version(self, version: &'static str) -> OrderDomain

Override the protocol version used in the EIP-712 domain separator.

The default is "v2".

Arguments

• version - The protocol version string.

Returns

self with the updated version.

pub const fn with_verifying_contract(self, contract: Address) -> OrderDomain

Override the verifying contract address.

The default is the canonical GPv2Settlement contract. Use this when computing domain separators for alternative deployments.

Arguments

• contract - The verifying contract address.

Returns

self with the updated verifying contract.

pub const fn with_chain_id(self, chain_id: u64) -> OrderDomain

Override the chain ID.

Arguments

• chain_id - The EVM chain ID.

Returns

self with the updated chain ID.
