Usage

Do a simple jsonrpc call

the default rpc endpoint is your local: http://localhost:8545

your command is like web3-cli jsonrpc_method [jsonrpc_param...]

$ web3-cli web3_clientVersion
"Geth/v1.12.1-unstable-60070fe5-20230805/darwin-amd64/go1.20.7"
$ web3-cli eth_getBlockByNumber 1 false

}

web3-cli supports built-in chain config as well.

$ web3-cli --chain eth eth_blockNumber
"0x1142cb9"
$ web3-cli --chain bsc eth_chainId
"0x38"

You can run web3-cli chains to get all built-in chain configs.

Of course, you can also use your own rpc endpoint

$ web3-cli --rpc https://rpc.ankr.com/arbitrum eth_chainId
"0xa4b1"

Call a contract with human-readable params

$ export USDT_TOKEN=0xdac17f958d2ee523a2206206994597c13d831ec7
$ web3-cli --chain eth --abi-name erc20 --call-to $USDT_TOKEN symbol
[
    "USDT"
]
$ web3-cli --chain eth --call-to $USDT_TOKEN balanceOf 0x0000000000000000000000000000000000000000
[
    "0xbf17d330"
]

the --abi-name could be a built-in abi name, you can web3-cli abis to get the built-in abi list.

and it also could be a url and file path.

$ web3-cli --chain eth --abi-path https://http-server/abi/abi.json
$ web3-cli --chain eth --abi-path local/path/to/abi.json

if you don't provide --abi-name or --abi-path, web3-cli can fetch the abi from explorer api automatically

$ web3-cli --chain eth --call-to $USDT_TOKEN getOwner
[
    "0xc6cde7c39eb2f0f0095f41570af89efc2c1ea828"
]

you may need to provide your explorer api endpoint as well if you provide a custom rpc

$ # not required if use a built-in chain
$ web3-cli --chain eth --rpc https://my-own-rpc.com
$ web3-cli --rpc https://my-own-rpc.com --explorer-api https://my-custom-explorer.com/api

What about a complex abi type parameter, like array and tuple?

bytes

function logbyt(bytes memory) public returns (bytes memory)

you must use a hex string

0x776562332d636c6920697320736f20636f6f6c21

array and slice

function add(uint256[] calldata items) public pure returns (uint256)

json array is valid

["0x1", 100]

tuple(struct)

struct Payment {
    address payable to;
    uint256 value;
}

function transfer(Payment calldata item) external payable returns (bool success) {
    return item.to.send(msg.value);
}

json array is valid (you can use it in Remix)

["0x0000000000000000000000000000000000000000", "0x1"]

json object is valid as well!

the key is the field name, and it is not case sensitive.

{ "to": "0x0000000000000000000000000000000000000000", "value": "0x1" }
{ "To": "0x0000000000000000000000000000000000000000", "Value": "0x1" }

Built-in tools

Create a new address with optional prefix and suffix

$ web3-cli tools new-random-address --prefix 00 --suffix 00
{
    "Address": "0x00BbEA9643992F70879a1f4009a18c82B14f1A00",
    "PrivateKey": "0xc44591dd44df800b1f9$REDACTED$be239403741b2196ca28",
    "PublicKey": "0x044708bac89fd0c4f595b0808c068350cf889d7aeea67848498997458c0541da955a7b6c8aafd5e8fbe00edfabb2d47da9fee680b711b2ce90401145ffce90defe"
}

Decode raw transactions

NOTE: OP system transactions are not supported.

$ web3-cli tools decode-raw-tx 0x...REDACTED...
{
    "type": "0x2",
    "chainId": "0x1",
    "nonce": "0x1018",
    "to": "0x388c818ca8b9251b393131c08a736a67ccb19297",
    "gas": "0x565f",
    "gasPrice": null,
    "maxPriorityFeePerGas": "0x0",
    "maxFeePerGas": "0x50c81c068",
    "value": "0x475c0000a4d611",
    "input": "0x",
    "accessList": [],
    "v": "0x1",
    "r": "0xa5a963fee24751d6f54656be527c699584ef47aade8a677c806f119b02b0daf7",
    "s": "0x257af2dbf67d167dfbf4f4acf032b43ca4fa8b8f06ae8b09f16bd2cc57817ce4",
    "yParity": "0x1",
    "hash": "0x048117077d33c6f3670d601de5525dda41374719162cb0ed252726559d4ffe70"
}

How to add your chain to built-in list?

Add it to internal/chains/list.go file.

for example:

var example = &Chain{
	Name:     "example",
	Id:       111000111,
	Endpoint: "https://jsonrpc-endpoint.example",
	Explorer: "https://full-explorer-api-endpoint.example/api",
}

then append it to Builtin slice.

you also need to add a test case for it in internal/chains/explorer_api_test.go

How to add an ABI to built-in list?

Add a valid json file to internal/abis/abi directory.
