Documentation

Requirements

PHP >= 8.4
Laravel 11, 12 or 13
GMP PHP extension (ext-gmp) installed and enabled

Installation

Install the package via composer:

composer require farbcode/laravel-evm

You can publish the config file with:

php artisan vendor:publish --tag="evm-config"

Then set your blockchain RPC URL, chain id and private key in .env:

EVM_CHAIN_ID=137
EVM_RPC_1=https://polygon-mainnet.g.alchemy.com/v2/KEY
EVM_PRIVATE_KEY=0xabc123...64hex

Usage (Quick Glimpse)

use Farbcode\LaravelEvm\Facades\Evm;

$abi = file_get_contents(storage_path('app/abi/MyContract.abi.json'));
$contract = Evm::at('0xYourContract', $abi);

// Read call - integers come back as decimal strings
$balance = $contract->call('balanceOf', ['0xUser'])->as('uint256');

// Write (async - enqueued on EVM_QUEUE default:evm-send, see https://laravel-evm.farbcode.net/basic-usage#writes-async-transactions for more information)
$jobId = $contract->sendAsync('transfer', ['0xRecipient', 100]);

Wait for a known tx hash. A receipt only proves inclusion, so check the status before treating it as a success:

use Farbcode\LaravelEvm\Support\Receipt;

$receipt = $contract->wait('0xTxHash');

if (Receipt::isSuccessful($receipt)) {
    // mined and did not revert
}

Log Filtering & Event Decoding

use Farbcode\LaravelEvm\Facades\EvmLogs;
use Farbcode\LaravelEvm\Support\LogFilterBuilder;

$abi = file_get_contents(storage_path('app/abi/ERC20.abi.json'));
$logs = EvmLogs::query()
    ->fromBlock(18_000_000)
    ->toBlock('latest')
    ->address('0xToken')
    ->eventByAbi($abi, 'Transfer')
    ->topicAny(1, [LogFilterBuilder::padAddress($addrA), LogFilterBuilder::padAddress($addrB)])
    ->get();
$decoded = array_map(fn($l) => LogFilterBuilder::decodeEvent($abi, $l), $logs);
