Do I need to swap ADA from 2018? They were on binance. How can I tell what version of the token I own? Thanks
This would be a question for your exchange, binance, not for this forum. How they manage your funds is their business. If you want to be sure, you can always run Daedalus or Yoroi and send your funds from binance to your wallet.
Remember: Not your keys, not your coins. Do not store ADA on exchanges if you do not want to be exposed to counterparty risk.
You don’t need to convert them; practically, there are no versions of the tokens, but there are versions of the wallets.
