Bech32m Addresses

protocol.bech32m-addresses

Bech32m is the checksum format used for native segregated witness addresses with version 1 and higher. It preserves the human-readable, error-detecting structure of Bech32 while changing the checksum constant so wallets can distinguish newer witness versions such as Taproot from version-0 segwit addresses.
