Module Polymarket_common.Order_signingSource

EIP-712 order signing for CTF Exchange.

This module provides the cryptographic primitives for signing orders compatible with Polymarket's CTF Exchange contract. Used by both CLOB and RFQ APIs.

Sourceval generate_salt : unit -> string

Generate a random salt as a decimal string. Uses 63 bits of randomness.

Sourceval order_type_hash : string

EIP-712 type hash for CTF Exchange Order struct.

Sourceval ctf_domain_separator : string

EIP-712 domain separator for CTF Exchange (Polygon mainnet).

Sourceval sign_order : private_key:Crypto.private_key -> salt:string -> maker:string -> signer:string -> taker:string -> token_id:string -> maker_amount:string -> taker_amount:string -> expiration:string -> nonce:string -> fee_rate_bps:string -> side:int -> signature_type:int -> string

Sign an order using EIP-712.
