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 0xErc20Contract1 0xErc20Contract2

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

Support pipe

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

Convert hexadecimal to decimal and vice versa

Support pipe

devd convert hex_2_dec [hexadecimal]
# devd c h2d 0x16a
# devd c h2d 16a
# echo 16a | devd c h2d
devd convert dec_2_hex [decimal]
# devd c d2h 170
# echo 170 | devd c d2h

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);'

Convert input into upper/lower case

Support pipe

devd convert to_lower_case [input]
# devd c lowercase AA
# echo AA | devd c lowercase
devd convert to_upper_case [input]
# devd c uppercase aa
# echo aa | devd c uppercase

Encode/Decode base64

Support pipe

devd convert encode_base64 [input]
# devd c base64 123
# echo 123 | devd c base64
devd convert decode_base64 [base64]
# devd c decode_base64 TVRJeg==
# echo TVRJeg== | devd c decode_base64

Convert raw balance into display balance and vice versa

devd convert display_balance [raw balance] [exponent]
# devd c dbal 10011100 6
# > 10.0111

devd convert raw_balance [display balance] [exponent] [--decimals-point , or .]
# devd c rbal 10.0111 6
# > 10011100
# devd c rbal 10,0111 6 -d ,
