You need to identify first before linking an address. If you haven't done so yet, you can register in "My Profile" in Bridge Wallet's settings tab.
To link a Bitcoin or Tezos address, you will have to switch to the Bitcoin or Tezos network using the icon on the top left of the app screen.
For Arbitrum, Avalanche, BNB Chain, Ethereun, Fantom, Optimism, Polygon and Gnosis, your address is the same on each of these networks. Therefore, it doesn't matter from which network you link it.
However, the cost of making the linking verification transaction will be much cheaper on sidechains and L2 than Ethereum so we recommend you to link an address from one of those networks.
Here are the cryptocurrencies that you will need to use to link your address according to the chosen network:
Go in the "Addresses" tab of Bridge Wallet's main menu, then click the "Link an address" button.
Type or scan the public address that you want to link.
This step shows you information on the address you have just entered. You can give it a name, and you must confirm that you are the owner of that address.
To enact the link of the new address with your identification profile, we must verify that you are in full control of the new address that you want to link for security and compliance reasons.
To do so, you will need to make a confirmation transaction (also known as a Satoshi test) from the new address to your Bridge Wallet address. We'll be able to confirm this way that you are able to send from that address.
Make sure that you send the exact amount displayed by the app (not this one). It is a very tiny amount that is a unique identifying code used to validate your transaction.
That's it! We will verify your confirmation transaction, which can take up to 48 hours. You will receive a notification as soon as your linked address is validated. In the meantime, you will see it in a pending (grey) status.
