A collection of CLI tools to help with ethereum learning and development.
Some things that can be done with it:
-
Get the hash for a given method signature:
$ eth method 'transfer(address,uint256)' a9059cbb -
Get the address where a contract will be deployed, given the address of the account that will create it and its nonce:
$ eth contract-address 0x90f8bf6a479f320ead074411a4b0e7944ea8c9c1 5 0xd833215cbcc3f914bd1c9ece3ee7bf8b14f841bb -
Get the transaction object for a given transaction hash (using the node running in
localhost:8545):$ eth tx 0x11aaa599233219609a6d40f85f9b3e10aacdd84c3f7826081bcec939ab227434 { "blockHash": "0x2302dff09eed5155076defa755a47759af978343893bd19db66b8acce0fba255", "blockNumber": 1000000, ... "v": "0x2b", "r": "0xe094dc11101ba5a659c5cbf5b9759efed7e774be7022c3bbde0edbd82d48e629", "s": "0x1b1aabe3fa700be3bcbcd99e7e6fc6cab37dd63a8240f3f62ce50c848fa00cea" } -
Start a REPL that connects to the node running in
localhost:8545, exposes theweb3andethobjects, and resolves promises automatically:$ eth repl > eth.getTransactionCount('0x90f8bf6a479f320ead074411a4b0e7944ea8c9c1') 331 -
Start a REPL that connects to the node running in
localhost:8545and loads a contract given its ABI and address. The contract is exposed asContractand promises are resolved automatically:$ eth load-contract path/to/contract.abi 0xd833215cbcc3f914bd1c9ece3ee7bf8b14f841bb > Contract.methods.add(2, 2).call() 4
npm install -g eth-cli
