Address type flags determine which address types a payment code accepts. This is represented by big-endian ordered 16 bits. For instance, a hypothetical payment code that handles all address types will have all defined bits set to 1.
Address type flags determine which address types a payment code accepts. This is represented by big-endian ordered 16 bits. For instance, a hypothetical payment code that handles all address types will have all defined bits set to 1 (<code>0xffff</code>).
Currently defined flags:
* 0x0001 - P2PKH
* 0x0002 - P2WPKH
* 0x0004 - P2TR

The remaining flags are reserved for future address types.
