AMM playground

The real Rust engine, compiled to WebAssembly and run live in your browser. Move the reserves, fee, and input size and watch the exact constant-product output update instantly, computed with the identical integer arithmetic the chain uses at settlement. Spot price and effective rate are display-only. Everything here is a simulation, read-only, no funds at risk.
