# Move between chains

> A move between chains is an intent. Every bridge that can carry it is quoted at once and ranked by what lands and how soon, then followed from leaving to landing.

## Say where, not how

A move is an **intent**: from which chain, to which chain, which token, how much, and optionally the token it should land as. ftw.trade quotes every route that can carry it and picks one:

| Preference | Picks |
|---|---|
| `auto` (default) | What lands the most among routes that land within two minutes, waiting longer only to save 5 bps or more |
| `cheapest` | What lands the most |
| `fastest` | What lands soonest |

You can also name one bridge.

## The bridges

- **Relay** carries most tokens across 50+ chains, Solana and the perps ledgers, in seconds.
- **Circle CCTP** carries USDC between Circle's chains: fast (about 20 seconds, about a basis point) or standard (no protocol fee, about 15 minutes from Ethereum and its rollups).

## Quote, send, follow

1. **Quote**: every route, what each lands (and the least it may), its cost and time, and which it would pick. Nothing is sent.
2. **Send** from each wallet. On paper it's quoted and nothing moves.
3. **Follow** each transfer: sent, landed, failed or refunded.

The same routing runs in workflows (a `bridge` step), scripts (`wallet.bridge(...)` within the policy's bridge limit) and protocol strategies, which bridge out and home by themselves.
