## MAIN CONFIG

## CREATE NEW ACCOUNT

# from a seed
$seed = 'your mnemonic seed phrase';
$account = PrivateKey::fromSeed( $seed );

# or from a random seed
//$seed = Functions::getRandomSeedPhrase();
//$account = PrivateKey::fromSeed( $seed );

# or from a raw 32 bytes private key (32 bytes)
//$privateKeyBytes = random_bytes( 32 );
//$account = PrivateKey::fromBytes( $privateKeyBytes );

# or from a base58 encoded private key
$account = PrivateKey::fromString( $account->toString() );

# a public key is used as a sender
$sender = $account->publicKey();

# address from the public key

## TRANSFER EXAMPLE

$recipient = Recipient::fromAddressOrAlias( 'test' ); // from alias
$recipient = Recipient::fromAddressOrAlias( '3N9WtaPoD1tMrDZRG26wA142Byd35tLhnLU' ); // from address
