NAME

Blockchain::Ethereum::Keystore - Ethereum wallet management utilities

VERSION

version 0.011

SYNOPSIS

Generating a new address and writing it to a keyfile:

            

              
              
my $key = Blockchain::Ethereum::Keystore::Key->new;
# checksummed address
print $key->address;
my $keyfile = Blockchain::ethereum::Keystore::Keyfile->new;
$keyfile->import_key($key);
$keyfile->write_to_file("...");
...
            
          

Generating a new seed and derivating new keys (BIP44):

            

              
              
my $seed = Blockchain::Ethereum::Keystore::Seed->new;
my $key = $seed->derive_key(0);
print $key->address;
...
            
          

Importing a keyfile and changing the password:

            

              
              
my $keyfile = Blockchain::Ethereum::Keystore::Keyfile->new;
my $password = "old_password";
$keyfile->import_file("...", $password);
$keyfile->change_password($password, "new_password");
$keyfile->write_to_file("...");
            
          

Signing a transaction:

            

              
              
my $transaction = Blockchain::Ethereum::Transaction::EIP1559->new(
    ...
);
my $keyfile = Blockchain::Ethereum::Keystore::Keyfile->new;
$keyfile->import_file("...");
$keyfile->private_key->sign_transaction($transaction);
            
          

Export private key:

            

              
              
my $keyfile = Blockchain::Ethereum::Keystore::Keyfile->new;
$keyfile->import_file("...");
# private key bytes
print $keyfile->private_key->export;
            
          

OVERVIEW

This module provides a collection of Ethereum wallet management utilities.

Core functionalities:

• Manage Ethereum keyfiles, facilitating import, export, and password change.

• Sign Blockchain::Ethereum::Transaction transactions.

• Private key and seed generation through Crypt::PRNG

• Support for BIP44 for hierarchical deterministic wallets and key derivation.
