Quote
BRDG asks every venue that serves the route for a price. Each one answers with an output amount, its fees and an estimated time, or appears in
rejected with the reason it could not quote. The answers are ranked by net output. See Ranking.2
Build
Building a quote returns the unsigned transactions for the route you chose: a token approval if one is needed, a fee transfer if the venue cannot collect the fee itself, then the bridge transaction. The transfer is recorded at this point, so you can look it up by id even if the user never signs.
3
Sign
The user’s wallet signs the steps in order. BRDG never signs anything for the user. Wallets that support EIP-5792 batching can sign the fee and bridge steps as a single bundle.

Submit
Send BRDG either the signed transaction, which it broadcasts for you, or the hash of a transaction the wallet already sent. BRDG checks it against the steps it built and refuses anything that does not match.
5
Track
BRDG follows the transfer with the venue until it finishes. Read
GET /bridge/transfers/{id} whenever you want the current status. The statuses are listed in Track a transfer.
