Bridge FAQs

Bridge is an asset router that combines thirdweb's own onchain infrastructure with existing bridging and swapping protocols to find the optimal route for any given transaction. This can include intents, native bridges, third party bridges, cross-chain messaging protocols, thirdweb's custom bridges, and more. All routes are monitored and planned continuously for health, price, and speed to guarantee the best path every time.

Yes, Bridge is designed to be agnostic to wallet infrastructure. You can use it with any wallet service.

thirdweb does not charge any fees for buy with fiat. Any fees on onramping are based on the onramp provider.

For buying with crypto or swap fees, thirdweb charges a 0.3% protocol fee. Developers may monetize their application by charging additional fees on swap transactions. To set a fee in your project page, navigate to Payments > Settings to set this fee.

Network fees, also referred to as miner fees, are paid to the miner for processing crypto transactions and securing the respective network. These fees do not go to thirdweb.

Fiat payouts are not currently available.
