Install

go install -v github.com/bcdevtools/devd/cmd/devd@latest

Query tools

Lazy RPC setting

export DEVD_EVM_RPC='https://api.securerpc.com/v1'

By setting this environment variable, you don't need to pass --rpc flag everytime for non-localhost EVM Json-RPC

Query account balance

devd query balance [account_address] [optional_erc20_contract_addresses...] [--rpc http://localhost:8545]
# devd q b 0xAccount
# devd q b ethm1account
# devd q b 0xAccount 0xErc20Contract
# devd q b ethm1account 0xErc20Contract 0xErc20Contract

Query ERC20 token information

devd query erc20 [erc20_contract_address] [optional_account_address] [--rpc http://localhost:8545]
# devd q erc20 0xErc20Contract
# devd q erc20 0xErc20Contract 0xAccount
# devd q erc20 0xErc20Contract ethm1account

Get EVM transaction information

devd query eth_getTransactionByHash [0xHash] [--rpc http://localhost:8545]
# devd q tx 0xHash

Get EVM transaction receipt

devd query eth_getTransactionReceipt [0xHash] [--rpc http://localhost:8545]
# devd q receipt 0xHash

Get EVM block by number

devd query eth_getBlockByNumber [hex or dec block no] [--full] [--rpc http://localhost:8545]
# devd q block 0xF
# devd q block 16 --full

Trace EVM transaction

devd query debug_traceTransaction [0xHash] [--tracer callTracer] [--rpc http://localhost:8545]
# devd q trace 0xHash
# devd q trace 0xHash --tracer callTracer

Convert tools

Convert address between different formats

devd convert address [address] [optional_bech32]
# devd c a 0xAccount ethm
# devd c a ethm1account
# devd c a ethm1account xyz

WARN: DO NOT use this command to convert address across chains with different HD-Path! (eg: Ethermint 60 and Cosmos 118)

Encode string into ABI or decode ABI into string

devd convert abi_string [string or ABI encoded string]
# devd c abi_string 000000000000000000000000000000000000000000000000000000000000002000000000000000000000000000000000000000000000000000000000000000045553444300000000000000000000000000000000000000000000000000000000
# devd c abi_string USDC Token

Convert hexadecimal to decimal and vice versa

devd convert hex_2_dec [hexadecimal or decimal]
# devd c h2d 0x16a
# devd c h2d 362
# devd c h2d 16a

Convert Solidity event/method signature into hashed signature

devd convert solc_sig [event/method signature]
# devd c solc_sig 'transfer(address,uint256)'
# devd c solc_sig 'function transfer(address recipient, uint256 amount) external returns (bool);'
# devd c solc_sig 'event Transfer(address indexed from, address indexed to, uint256 value);'

Debug tools

Compute EVM transaction intrinsic gas

devd debug intrinsic_gas [0xdata]
# devd d intrinsic_gas 0xdata
