Swarm’s dOTC v2 (Decentralized Over-The-Counter) protocol enables peer-to-peer asset trading directly on-chain, combining the flexibility of off-chain price discovery with the security and transparency of on-chain settlement.

This system supports:

• Permissionless creation of OTC offers (ERC-20, ERC-721, ERC-1155)
• Dynamic pricing using live oracle feeds
• Partial or full fills with flexible offer types
• Escrow-based settlement on Ethereum, Polygon, and Base

Below is a quick guide to the core components of dOTC v2.
