How It Works
PrimeTrade connects directly to the PrimeOrders precompile—a native on-chain order matching engine embedded at the EVM level. Unlike AMM-based DEXes, PrimeTrade uses a Central Limit Order Book (CLOB) model where:
- Limit orders rest on the book at a specified price until filled or cancelled
- Market orders execute immediately against the best available resting orders
- Matching is atomic and happens within a single transaction via the precompile
