How to link a wallet address

Getting started

If not already done, you first need to register with us. You can do so:

On our website

On our web interface, click on the person icon on the top right of the widget, do the SMS code verification and provide an email address.

In Bridge Wallet

Download and install the app, then create or restore a wallet. Go in Settings > My profile > Register, then choose one of the available authentication modes to create your user profile.

Link a Bitcoin address from a Ledger or a Trezor

Go on our web interface, choose to buy or sell Bitcoin and click on the green "Buy" button. On the "Receiving address" screen, choose the Ledger or Trezor option (or click "Connect another wallet" if you already have an address), then approve the signature request on your hardware wallet.

Make sure that your hardware wallet is updated, properly connected to your computer, unlocked and opened on the Bitcoin app/account.

Link a Bitcoin address from any other wallet

You will need to make what is called a satoshi test, which is a transaction with a tiny amount of BTC (a fraction of a cent) sent from the address that you want to link to our verification address. Make sure to send the exact amount indicated, as it is a unique code required for our system to automatically detect and validate your transaction.

Link an Ethereum address from a hardware wallet

For this, you will need a browser wallet that supports connections with hardware wallets. We recommend using Rabby Wallet.

Link an Ethereum address from a mobile wallet

A wallet address is the same on Ethereum and on all Ethereum-compatible networks (Arbitrum, Avalanche, BNB Chain, Fantom, Gnosis Chain, Optimism, Polygon, Rootstock), you can therefore link an address from any of these chains.

If you open our interface from a computer, scan the QR code from your mobile wallet and approve the request there.

If you open our interface from a mobile phone, click on "Connect" and approve the request in your mobile wallet.
