ERC20 Tokens

Interact with any ERC20 standard Ethereum token

This package is ultimate response to historic issue of no native API being available to PHP developers to interact with ERC20 tokens (i.e. web3js contracts API).

This package communicates directly with Geth using RPC (furqansiddiqui/ethereum-rpc) and performs all ABI encoding and decoding in background, resulting in pure simple and easy to use API for developers to perform all ERC20 standard operations.

Demo

  • A random ERC20 token was picked from a list, given contract address 0xd26114cd6EE289AccF82350c8d8487fedB8A0C07
$geth = new EthereumRPC('127.0.0.1', 8545);
$erc20 = new \ERC20\ERC20($geth);
$token = $erc20->token('0xd26114cd6EE289AccF82350c8d8487fedB8A0C07');

var_dump($token->name());
var_dump($token->symbol());
var_dump($token->decimals());

Result:

string(8) "OMGToken"
string(3) "OMG"
int(18)

Installation

composer require furqansiddiqui/erc20-php

Prerequisites

ABI

A standard ERC20 ABI file is included in package residing in "data" directory.

Path to a custom ABI may be specified when constructing ERC20 token object.

$geth = new EthereumRPC('127.0.0.1', 8545);
$erc20 = new \ERC20\ERC20($geth);
$erc20->abiPath('/path/to/abi.json');
