COA is the native currency of the Alliance Games Arcade. It is used to:

• Play additional sessions beyond the free ones

• Receive rewards from the Arcade prize pool

This guide explains how to bridge COA tokens between BSC, BASE, and the Alliance Games blockchain using the Chromia Vault.

1. Accessing the Chromia Vault

The Chromia Vault is the central hub for managing token balances across Chromia dapp chains.

• Visit: https://vault.chromia.com

• Connect the same wallet you use for the Alliance Games Arcade

• Your COA balance will appear automatically if you’ve earned tokens from the leaderboard
  
  
  

2. Creating a Chromia Token Chain Account

To bridge COA, you must first have an account on the Chromia Token Chain.

Step 1: Deposit CHR to the Economy Chain

1. Open the Chromia Token Chain dapp:
   https://vault.chromia.com/en/dapps/dapp/?dapp=1807-Chromia+Token+Chain

2. Click Activate
   
   

   

3. Click Go to deposit page
   
   

   

4. Deposit COA tokens from any supported network into the Chromia Token Chain
   
   

   

This creates your Token Chain account, which is required for transferring COA to and from the Arcade.

3. Bridging COA Tokens

Once your Token Chain account is ready, you can now:

• Deposit COA from BSC or BASE

• Withdraw COA back to BSC or BASE

• Transfer COA to and from the Alliance Games Arcade dapp

⚠️ Important:
When transferring COA to play in the Arcade, make sure you send it to the Alliance Games Arcade chain, not the Hub.
