nautilus_polymarket::signing::eip712

Struct OrderSigner 

Source 
pub struct OrderSigner { /* private fields */ }
Expand description

EIP-712 order signer for the Polymarket CTF Exchange.

Implementations§

Source§

impl OrderSigner

Source

pub fn new(private_key: &EvmPrivateKey) -> Result<Self>

Creates a new OrderSigner from an EVM private key.

Source

pub fn with_signer_type(self, signer_type: PolymarketSignerType) -> Self

Selects the signer role. Session signing requires POLY_1271 orders.

Source

pub fn address(&self) -> Address

Returns the signer’s Ethereum address.

Source

pub fn sign_order( &self, order: &PolymarketOrder, neg_risk: bool, ) -> Result<String>

Signs a PolymarketOrder and returns the hex-encoded ECDSA signature.

The neg_risk flag selects which exchange contract to use as the EIP-712 verifyingContract.

§Errors

Returns an error if a non-POLY_1271 order signer does not match this signer’s address, or if a POLY_1271 order does not use the deposit wallet for both maker and signer.

Source

pub fn sign_deposit_wallet_batch( &self, deposit_wallet: Address, nonce: U256, deadline: U256, calls: &[DepositWalletCall], ) -> Result<String>

Signs a Deposit Wallet Batch and returns the hex-encoded ECDSA signature.

§Errors

Returns an error if calls is empty or signing fails.
