Overview

The Symmio Options Protocol is an intent-based options trading system for peer-to-peer options without traditional market makers. It runs on the EVM and settles bilaterally: two parties, PartyA and PartyB, enter an option contract backed by on-chain collateral.

The protocol uses the EIP-2535 Diamond pattern, splitting functionality into modular facets over shared storage. Options are ERC-721 NFTs: the holder has the right, but not the obligation, to buy or sell the underlying tokens at a set price and expiration.
