```perl
    # parameters can be hexadecimal strings or Math::BigInt instances
    my $transaction = Blockchain::Ethereum::Transaction::EIP1559->new(
        nonce                    => '0x0',
        max_fee_per_gas          => '0x9',
        max_priority_fee_per_gas => '0x0',
        gas_limit                => '0x1DE2B9',
        to                       => '0x3535353535353535353535353535353535353535'
        value                    => Math::BigInt->new('1000000000000000000'),
        data                     => '0x',
        chain_id                 => '0x539'
    );

    # github.com/refeco/perl-ethereum-keystore
    my $key = Blockchain::Ethereum::Keystore::Key->new(
        private_key => pack "H*",
        '4646464646464646464646464646464646464646464646464646464646464646'
