The transactions that correspond to bridge transfers will appear on explorers for the Avalanche and Bitcoin networks. It may take a few minutes for the transactions to appear. To search for your transaction in the explorer, copy and paste your address into Avalanche's C-Chain Explorer or Blockchain.com. To view the transactions sent by the bridge itself, you can look here for Avalanche and here for Bitcoin. If you still don't see your transaction, reach out on Telegram or Discord. Please be wary of anyone you are not familiar with offering to help, as they may be scammers attempting to obtain your Recovery Phrase or private keys.
