NAME

Blockchain::Ethereum::Transaction - Ethereum transaction abstraction

VERSION

version 0.009

SYNOPSIS

Ethereum transaction abstraction for signing and generating raw transactions

    # 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'
    );

    $key->sign_transaction($transaction);

    my $raw_transaction = $transaction->serialize;

    print unpack("H*", $raw_transaction);

METHODS

serialize

To be implemented by the child classes, encodes the given transaction parameters to RLP

Returns the RLP encoded transaction bytes

generate_v

Generate the transaction v field using the given y-parity

• $y_parity y-parity

Returns the v hexadecimal value also sets the v fields from transaction

hash

SHA3 Hash the serialized transaction object

Returns the SHA3 transaction hash bytes
