Protocol Features

Designed for Decentralized Liquidity and Matchmaking

Order prices adjust over time using configurable slopes. Buy orders decrease while sell orders increase, creating natural market convergence.

Autonomous keepers scan and match compatible orders using an efficient O(N log N) two-pointer sweep algorithm for optimal execution.

Deploy across Ethereum, Ethereum Classic, Polygon, BSC, and Base with pre-configured RPC endpoints and contract verification.

A flat 0.1% keeper fee per matched order. No hidden costs, no front-running — everything is settled atomically on-chain.

Deploy dynamic price curves, configure slopes, and let keepers settle your orders at optimal rates on any supported EVM chain.
