# 14. Protocol Evolution: Expanded Route Reachability

Baltex Protocol extends route reachability by expanding the underlying liquidity graph:

* **More venue adapters and liquidity sources:** additional CEX/DEX/provider edges added to the route graph.
* **More candidate routes per request:** k-best search runs over a larger graph, surfacing more viable paths.
* **Improved fallback and viability filtering:** better handling of venue constraints ensures only executable routes are scored and returned.

Partner integrations remain stable: the same `quote`/`create`/`status` methods are used; the protocol primarily changes the set of routable pairs and the quality/availability of routes.
