ERC20 Tokens

Interact with any ERC20 standard Ethereum token, _(*2)

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)., _(*3)

This package communicates directly with Geth using RPC (lidelin/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., _(*4)

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:, _(*5)

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

Installation

composer require lidelin/erc20-php, _(*6)

Prerequisites

• PHP >= 7.1+
• Ethereum RPC client (lidelin/ethereum-rpc) >= 0.1.2

ABI

A standard ERC20 ABI file is included in package residing in "data" directory., _(*7)

Path to a custom ABI may be specified when constructing ERC20 token object., _(*8)

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