1. #How to check the hot wallet balance (Ethereum / ERC20)?

   • Copy a wallet address which balance you want to check.
   • Go to the Etherscan and past in the search the wallet address.
   • When the wallet info is loaded, check the balance of the wallet.

2. #How to export the private key of the hot wallet?

   Private keys can be exported only for wallets which private keys stored on the blockchain node. To export a private key of an account you need to have access to your blockchain node and to know the passphrase for the account you want to export. Export is done in JSON format. You can then save this JSON into a file and import it to Metamask.

   1) Curl a Parity node to get the JSON response

   curl --data '{"method":"parity_exportAccount","params":["*account address*","*account_password*"],"id":1,"jsonrpc":"2.0"}' -H "Content-Type: application/json" -X POST localhost:8545 | jq -c .result
   

   2) Save the received JSON data to a file.

   3) If you need to interact with the extracted wallet, import the saved file to the Metamask.
