handles package

Overview

Package handles is a tiny on-chain nickname registry.

Any address may claim one unique handle (3-20 lowercase letters/digits, starting with a letter), attach a short bio, transfer the handle to another address, or release it back to the pool. It is deliberately small: two AVL indexes (handle -> record, address -> record) and a handful of guarded mutators.

Functions

Count

func Count() int

Count returns the number of currently registered handles.

Command

gnokey query vm/qeval -remote "https://rpc.test13.testnets.gno.land" -data "gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/handles.Count()"

Result

HandleOf

func HandleOf(addr address) (string, bool)

HandleOf returns the handle owned by addr, if any.

Param

Command

gnokey query vm/qeval -remote "https://rpc.test13.testnets.gno.land" -data "gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/handles.HandleOf()"

Result

Register

func Register(cur realm, handle string)

Register claims handle for the caller. Aborts if the handle is invalid, already taken, or the caller already owns a handle (release it first).
