Dex Protocols

Pure TypeScript implementations for DEX protocol reducers, quoters, pricers, and protocol math.

This package was extracted from cyclic-bot so protocol behavior can be tested with deterministic fixtures instead of live RPC, database, or app-context IO.

Current scope

• CPMM core
• CLMM core
• StableSwap core
• CryptoSwap core
• Aerodrome Slipstream and Volatile
• Curve
• Ekubo v2 and v3
• PancakeSwap v2 and v3
• SushiSwap v2 and v3
• Uniswap v2 and v3

The first extraction keeps the original internal source layout under src/dex-protocols to minimize churn. Public consumers should prefer the root module exports or explicit subpath imports.

Checks

pnpm run check
pnpm run build

Fixture direction

Live parity checks should be converted into committed fixtures under tests/fixtures. Test runs should replay those fixtures and must not call RPC providers, databases, indexers, or bot app contexts.
