Changelog: August 2026

The jupiter-amm-interface repository is now a Cargo workspace with a new jupiter-amm-test-kit crate. The test kit proves your Amm::quote() matches the on-chain program before you submit: it snapshots a live pool, runs your quote, executes the native swap instruction in LiteSVM, and asserts the on-chain token deltas equal the quote exactly.

• Write one PoolTest per pool plus a small encoder for your program's swap instruction data; an SPL Token Swap reference suite shows the full pattern
• Fixtures auto-snapshot from a live RPC (RPC=<mainnet-url> cargo test) and run offline once committed
• Submit your DEX for review through the new AMM integrators support form once parity tests pass

WTM (what this means) - You can verify your integration end to end on your own before reaching out, instead of waiting on Jupiter to test your SDK against simulation.
