ethx

Ethereum transaction pretty-printer. Etherscan.io for the command line.

Install

yarn global add @mohoff/ethx
# or
npm install -g @mohoff/ethx

Use

You can use ethx to wait for a transaction to reach a certain number of network confirmations or simply pretty-print a mined transaction.

# View transaction details
ethx [view] <transactionHash> -i infuraApiKey [-t timeout]

# Wait for a transaction to reach a certain number of network confirmations and print its details
ethx await <transactionHash> -i infuraApiKey [-c confirmations] [-t timeout]

Example

ethx await 0xfd53c77168e1726db0bb95fcbd7f9c44bd3fbe55797b2ecefdbb3cd91744c527 -c 10 -i <infuraApiKey>

Future features and ideas

• Support other providers than infura
• Show contract name (make calls to name() and getName())
• Switch networks with --network/--chain
• Output raw transaction objects with --raw
• Integrate Etherscan API to get verrified contract code
  • parse contract name
  • parse event names --> hash all to find match with tx logs
  • parse external functions --> hash all to find match with function signature
• Add historic gas stats from ethgasstation for that time (-5,+5min)
• From/To details: activity indicator, #tx since then, #tx overall, tx every Xh on avg, total ETH moved. Activity last 1h,24h,1d,1w,1m,1y,alltime --> activity horizontal bar with dots
• Refactor some parts to use websocket-provider to ease network load
• Gas usage in the block: bar graph (limit, used, this tx) --> With correct x-offset of current tx?
• Show line numbers in data output
• Make use of tx.transactionIndex --> Can we derive miner's priority in including a tx into the block?
• When functionName is known with 1+ params, the value type for the first few lines of tx.input can be derived
