The transactions that correspond to Avalanche Bridge™ transfers will appear on explorers for the Avalanche® and Ethereum 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 Snowtrace (Avalanche® C-Chain block explorer) or Etherscan. To view the transactions sent by the bridge itself, you can look here for Avalanche and here for Ethereum. If you still don't see your transaction, reach out on Telegram or Discord.
