Open-source DEX routing SDK for Canton: looking for feedback, DEX partners and a champion!

Hello everyone!

We’ve proposed an open-source SDK that routes swaps across Canton DEXs. You give it two tokens, and it returns the best route with an unsigned execution plan. Bridges, wallets and dApps can use it as the last-mile swap after bridging, without integrating each DEX separately.

No keys, no signing, no hosted backend, no fees. You run it yourself.

DEXs join by writing a small adapter and opening a PR. Once it’s merged, their liquidity is routable by every app using the SDK.

Questions for the community:

• DEX teams: would you maintain your own adapter? Cantex and TradeCraft are first on our list, and we’re open to more.
• Bridge and wallet builders: is the last-mile swap a real pain for you right now?

We’ve run cross-chain routing in production before, including on non-EVM L1s. Looking for a champion!

Thanks!
