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'
);

my $key = Blockchain::Ethereum::Keystore::Key->new(
    private_key => pack "H*",
    '4646464646464646464646464646464646464646464646464646464646464646'

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
