See [Route Providers](/sdk/quote-providers) for details on configuring bridge and swap providers.

## Non-EVM Edge Rails

In addition to EVM chains, Trails supports **edge rails** that bridge between non-EVM chains and the EVM intent flow. Edge rails are used as either the origin (funds enter the intent from a non-EVM chain) or destination (intent funds an address on a non-EVM chain) of a cross-chain intent.

| Chain  | Edge Modes          |
| ------ | ------------------- |
| Solana | Origin, Destination |
| Tron   | Origin, Destination |

Edge-rail availability can vary by deployment. Call [`GetEdges`](/api-reference/endpoints/get-edges) to discover which rails and modes are enabled, then use [`QuoteIntentEdge`](/api-reference/endpoints/quote-intent-edge) instead of `QuoteIntent` to price any intent that touches a non-EVM chain. Track the external leg with [`GetEdgeStatus`](/api-reference/endpoints/get-edge-status).

In the SDK, Solana wallets are wired in through the [`svmAdapter`](/sdk/adapters/solana).
