# Generate Transaction

`POST /v2/fungible/msgs`

This is the second step when bridging tokens. After computing a route with Compute Route (`POST /v2/fungible/route`), pass the route details and your addresses to this endpoint. It returns signable transaction messages that you can broadcast to the source chain.

The typical flow is: **Compute Route** → **Generate Transaction** → sign and broadcast → **Track Transaction**.
