ChainPal provides several commands to work with blockchain data:
Convert a value between hex and decimal and vice versa.
chain-pal convert <value>
- value: The value in hex or decimal format to be converted.
Convert a value in wei to gwei and ether, considering token decimals
chain-pal convert-unit-wei <value> <decimals>
- value: The value in wei to be converted.
- decimals: The number of decimals for the token (default: 18).
Convert a value in gwei to wei and ether, considering token decimals
chain-pal convert-unit-gwei <value> <decimals>
- value: The value in gwei to be converted.
- decimals: The number of decimals for the token (default: 18).
Convert a value in ether to wei and gwei, considering token decimals
chain-pal convert-unit-ether <value> <decimals>
- value: The value in ether to be converted.
- decimals: The number of decimals for the token (default: 18).
Process a CSV file containing transactions and output the transaction details,
considering the gas price and gas limit for EVM-like chains
chain-pal process-csv <httpEndpoint> <csvFilePath>
httpEndpoint: The HTTP endpoint for the JSON-RPC provider. It can be https://ethereum.publicnode.com
csvFilePath: The file path of the CSV to be processed.
must have the following format:
