Introduction
OISY TRADE is an order-book DEX on the Internet Computer.
Key features
- CEX-like experience — deposit once, trade as much as you want, withdraw anytime.
- Fully onchain order book — central limit order book (CLOB) running entirely within a single canister.
- Permissionless trading — any principal can trade on any active pair, no allowlisting required.
Architecture at a glance
- Single canister. All order-book state, matching, and settlement live in one canister.
- Synchronous matching engine. Token transfers only happen at the deposit and withdrawal edges; the matching engine operates entirely on internal balances, with no async complexity.
- Event-sourced state. Every state change is recorded in an append-only log in stable memory and replayed on upgrade, providing full auditability and simpler upgrades.
