VERSION

Version 0.002

SYNOPSIS

Allow RLP encoding and decoding

This class is basically an transpilation of the RLP encode/decode python sample given at https://ethereum.org/en/developers/docs/data-structures-and-encoding/rlp/

my $rlp = Blockchain::Ethereum::RLP->new();

my $tx_params  = ['0x9', '0x4a817c800', '0x5208', '0x3535353535353535353535353535353535353535', '0xde0b6b3a7640000', '0x', '0x1', '0x', '0x'];
my $encoded = $rlp->encode($params); #ec098504a817c800825208943535353535353535353535353535353535353535880de0b6b3a764000080018080

my $encoded_tx_params = 'ec098504a817c800825208943535353535353535353535353535353535353535880de0b6b3a764000080018080';
my $decoded = $rlp->decode(pack "H*", $encoded_tx_params); #['0x9', '0x4a817c800', '0x5208', '0x3535353535353535353535353535353535353535', '0xde0b6b3a7640000', '0x', '0x1', '0x', '0x']
