# OpenBridge

> Open a cross-network bridge session

The `DAppBridgeService` exposes a single RPC used to open bridge sessions between networks.

## Service

```proto theme={null}
service DAppBridgeService {
  rpc OpenBridge (OpenBridgeRequest) returns (OpenBridgeResponse);
}
```

## Example

```bash theme={null}
grpcurl rpc-devnet.modo-api.app:443 \
  list silvana.ledger.v1.DAppBridgeService

grpcurl rpc-devnet.modo-api.app:443 \
  describe silvana.ledger.v1.DAppBridgeService.OpenBridge
```

<Note>
  Use reflection to discover the full request/response schema of `OpenBridge` against the specific environment you are targeting — the exact fields may evolve independently of `DAppProviderService`.
