Examples

Generate a P2PK/P2PKH address:

$address = OutputFactory::p2pk($pubKey)->address(); 
$address = OutputFactory::p2pkh($pubKeyHash)->address(); 

Generate a P2MS address:

$address = OutputFactory::p2ms(2, [$pubKey1, $pubKey2, $pubKey3])->address();

Generate a P2SH address:

$factory = new OutputFactory();
$p2ms = $factory->p2ms(2, [$pubKey1, $pubKey2, $pubKey3]);
$address = $factory->p2sh($p2ms)->address();

Generate a P2WPKH address:

$address = OutputFactory::p2wpkh($pubKeyHash)->address();

Generate a P2WSH address:

$factory = new OutputFactory();
$p2ms = $factory->p2ms(2, [$pubKey1, $pubKey2, $pubKey3]);
$address = $factory->p2wsh($p2ms)->address();

Generate a P2WPKH-over-P2SH address:

$factory = new OutputFactory();
$p2wpkh = $factory->p2wpkh($pubKeyHash);
$address = $factory->p2sh($p2wpkh)->address();

Generate a P2WSH-over-P2SH address:

$factory = new OutputFactory();
$p2ms = $factory->p2ms(2, [$pubKey1, $pubKey2, $pubKey3]);
$p2wsh = $factory->p2wsh($p2ms);
$address = $factory->p2sh($p2wsh)->address();

Generate a P2TR address:

$taprootPubKey = Taproot::construct($pubKey);
$address = OutputFactory::p2tr($taprootPubKey)->address();

Generate an address from an output script:

$address = OutputFactory::fromScript($script)->address();

Decode a Bitcoin address:

$output = NetworkFactory::bitcoin()->decodeAddress('1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH');

Get a Bitcoin address type:

$type = NetworkFactory::bitcoin()->decodeAddress('1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH')->type(); // p2pkh

Validate a Bitcoin address:

NetworkFactory::bitcoin()->validateAddress('1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH'); // true
