SYNOPSIS

use strict;
use warnings;
use Ethereum::RPC::Client;

my $abi = ...;
my $bytecode = ...;
my $rpc_client = Ethereum::RPC::Client->new;

my $coinbase = $rpc_client->eth_coinbase;

    contract_abi    => $abi,
    from            => $from,
    gas             => $gas,
});

my $message = $contract->deploy($bytecode)->get_contract_address(35);

$message = $contract->invoke("functionname", qw(param1 param2 param3))->call_transaction();

$message = $contract->invoke("functionname", $param1, $param2, $param3)->send_transaction();

DESCRIPTION

perl-Ethereum-Contract is a library to enable perl to call the contract functions using RPC calls.

USAGE

• Calling RPC commands

      my $rpc_client = Ethereum::RPC::Client->new; 
      my $balance = $rpc_client->eth_getBalance("0x0...", "latest");

• Loading Contract

      my $rpc_client = Ethereum::RPC::Client->new; 
  
      my $contract = $rpc_client->contract({
          contract_abi    => $abi,
          from            => $coinbase,
          gas             => 3000000,
      });

• Deploying a Contract

      $contract->deploy($bytecode);

• Calling a Contract function

      my $message = $contract->invoke($function_name, param1, param2, ...)->call_transaction();
      $big_int = $message->get->to_big_int unless $message->is_failed;
