Why are some ERC20 tokens no longer supported?
Recently, the developers of some ERC20 tokens have decided to move their tokens to their own blockchain. Once migration is completed, the main net tokens no longer comply to the Ethereum network's ERC20 protocol and they use a blockchain that is separate from the Ethereum network.
If you would like to swap your ERC20 tokens for the main net tokens, the first step is to send these tokens to a platform that will support the swap. Each token developer will announce the details of token swaps in their own support channels.
If the deadline for the token swap has passed and you were unable to swap your ERC20 token for the main net tokens, please reach out to the token developer's support team for assistance.
You will see that wallet for these tokens are marked as disabled in your BRD app but they will still be accessible. If needed, you can find your token address by tapping on the "Receive" button in the wallet.
As long as it is still supported by the Ethereum network, you will be able to send these ERC20 tokens out from the BRD app to another platform that supports the token swap.
