Typelex Shows How to Cut Gas Costs for OTC Orders With Offchain Signatures

Typelex demonstrates a gas-efficient OTC order system using EIP-712 typed data and offchain signatures, reducing onchain storage for short-lived quotes. The architecture allows makers to sign orders offchain, which are only submitted when a trade settles, avoiding gas costs for expired quotes. This approach uses nonce-based replay protection and supports both EOAs and smart-contract wallets.
