In this tutorial we show you how to link an existing Bitcoin, Ethereum, Binance Smart Chain, Polygon or xDai wallet address to your Bridge Wallet.

A linked address allows you to:

1: Identify

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.

2: Choose your network

To link a Bitcoin address, you will have to switch to the Bitcoin network using the icon on the top left of the app screen.

For Ethereum, Binance Smart Chain, Polygon and xDai, an 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 BSC, Polygon and xDai than Ethereum so we recommend you to link an address from one of those three networks.

Here is the cryptocurrency that you will need to use to link your address on each network:

Network	Native crypto
Bitcoin	BTC
Ethereum	ETH
Binance Smart Chain	BNB
Polygon	MATIC
xDai	XDAI

3: Link a new address

Go in the "Addresses" tab of Bridge Wallet's main menu, then click the "Link an address" button.

4: Enter the address

Type or scan the public address that you want to link.

5: Name it and confirm

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.

6: Make the confirmation transaction

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.

7: Wait for verification

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.
