Hey all — I just open-sourced a Rust repo pulled out of a production DeFi/MEV system:

Dex-Math-Core-rs

Where it comes from

This code started life inside my live searcher stack and was extracted into a standalone crate so it can be reused, audited, and improved publicly.

What’s strong about it

• Deterministic integer math (fail-closed behavior, no “guess” fallbacks)
• Coverage across major AMM styles:
  • Uniswap V2
  • Uniswap V3 (concentrated liquidity)
  • Curve (StableSwap paths)
  • Balancer (weighted pools)
  • Kyber Elastic
• Production-focused edge-case handling + parity-oriented tests
• MIT licensed and structured for external contributions

How you can use it

• Searcher / MEV simulation pipelines
• On-chain routing + quote engines
• Liquidation sizing / slippage-aware execution
• Backtest/replay engines that need reproducible DEX math
• Building custom adapters for additional protocols

If you’re into AMM math correctness, rounding edge cases, or performance in Rust, I’d really appreciate feedback and PRs (especially new DEX math modules + parity tests).

If you spot anything wrong, please open an issue — accuracy > everything.
