amashukov/eth-rpc-client-php

Ethereum / EVM JSON-RPC client in pure PHP — raw eth_* mirror plus an ethers.js v6-style typed provider over any PSR-18 client, with EIP-1559 fee data.

An Ethereum JSON-RPC client in pure PHP for any EVM chain, built on any PSR-18 HTTP client. Two layers: a raw eth_* mirror (EthRpcClient) for audit-grade hex parity with the wire, and an ethers.js v6-flavoured facade (JsonRpcProvider) returning typed Value Objects — EthereumTransaction, EthereumTxBundle, EthereumBlock, EthereumFeeData, EthereumFeeHistory, EthereumTransactionLog. Wei values that exceed PHP_INT_MAX stay safe as decimal strings via ext-gmp, never lossy floats. EIP-1559 fee composition follows ethers.js (maxFeePerGas = 2 × baseFee + tip), and the provider gracefully handles real-world node quirks like Erigon's bare 0x returns and missing baseFeePerGas.

Features

• Two layers, one transport — EthRpcClient mirrors the eth_* namespace (eth_blockNumber, eth_getBalance, eth_call, eth_getTransactionByHash, eth_getTransactionReceipt, eth_getLogs, eth_feeHistory, …); JsonRpcProvider wraps it with typed Value Objects and ethers.js naming.
• Transport-agnostic — bring your own PSR-18 client + PSR-17 factories. Retry / key-rotation / load-balancing are middleware concerns, not baked in.
• Typed transaction surface — getTypedTransaction() / waitForTransaction() return an EthereumTxBundle with EIP-658 isStatusSuccess() / isStatusFail() / isStatusPending() predicates, so call sites never compare raw '0x1' / '0x0' strings.
• EIP-1559 fee data — getFeeData() mirrors ethers.js (maxFeePerGas = 2 × baseFee + tip); getFeeHistory() carries the gwei-median math.
• Node-quirk tolerant — handles Erigon's bare '0x' empty returns and pre-London / missing-baseFeePerGas blocks without throwing.
• Bigint-safe numeric helpers — Numeric\HexInt / HexBig / Wei.
• PSR-20 clock injection — waitForTransaction deadlines are driven by an injected Psr\Clock\ClockInterface, so polling is fully testable.

Why amashukov/eth-rpc-client-php

web3p/web3.php is effectively abandoned and predates EIP-1559 — no typed fee data, no London-fork fee composition. This package targets modern PHP 8.3, ships EIP-1559 fee math out of the box, returns typed Value Objects with bigint-safe decimal strings, keeps PHPStan level 9 across the surface, and stays transport-agnostic so retries and API keys live in your PSR-18 pipeline.

Installation

composer require amashukov/eth-rpc-client-php

Usage

use Amashukov\EthRpc\EthRpcClient;
use Amashukov\EthRpc\JsonRpcProvider;
use Amashukov\HttpClient\CurlClient;
use Nyholm\Psr7\Factory\Psr17Factory;
use Symfony\Component\Clock\NativeClock;

$psr17 = new Psr17Factory();
$http  = new CurlClient($psr17, $psr17, timeoutSeconds: 30);

$client   = new EthRpcClient($http, $psr17, $psr17, 'https://your-eth-node.example/rpc');
$provider = new JsonRpcProvider($client, new NativeClock());

$balanceWei = $provider->getBalance('0xabc...');           // decimal string
$bundle     = $provider->getTypedTransaction('0xtxhash');  // EthereumTxBundle
if ($bundle->isStatusSuccess()) {
    $gasFee = $bundle->receipt->fee;                        // decimal wei
}

$fee  = $provider->getFeeData();                           // EthereumFeeData
$usdt = $provider->getErc20Balance('0xdAC17...', '0xholder...');

Wire a retry / API-key pipeline by composing amashukov/http-client-php middlewares around the CurlClient and passing the resulting PSR-18 Pipeline into EthRpcClient.

Signing

This package broadcasts already-signed raw transactions via sendTransaction(). Offline EIP-1559 / EIP-155 signing lives in the companion amashukov/eip1559-tx-signer-php.

Requirements

• PHP 8.3+
• ext-gmp, ext-bcmath
• A PSR-18 client + PSR-17 request / stream factories + a PSR-20 clock
