Module dpns_usernames 

Transport-free DPNS username helpers.

The Sdk-bound DPNS surface (registration, availability checks, name resolution) lives in dash-sdk; these free functions are pure string validation/normalization shared with embedders.

Functions

convert_to_homograph_safe_chars

Convert a string to homograph-safe characters by replacing ‘o’, ‘i’, and ‘l’ with ‘0’, ‘1’, and ‘1’ respectively to prevent homograph attacks

is_contested_username

Check if a username is contested (requires masternode voting)

is_valid_username

Check if a username is valid according to DPNS rules
