handles

⚠️ Experimental — generated with no human supervision. This realm was produced automatically by an MCP-driven agent to exercise the gno MCP server and tooling, and to generate test content for gno compilers, linters and formatters. Not audited. Not for production. Full context & folder README: r/moul/x/daily

A tiny on-chain nickname registry. Any address can 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 into the pool. Two avl.Tree indexes (handle -> record, owner -> record) keep lookups in both directions cheap and deterministic.

Realm path: gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/handles

Example calls

Register(cur, "moul")          # claim the handle "moul" for the caller
SetBio(cur, "building gno stuff")
Transfer(cur, g1...recipient)  # hand the handle to another address
Release(cur)                   # free the handle back up
OwnerOf("moul")                 # (address, bool)
HandleOf(g1...)                 # (string, bool)
Count()                         # number of registered handles

Render("") lists every registered handle in a table; Render("/moul") shows a single handle's detail page (owner, bio, block registered).

Toolchain status

Built and tested against a local gno build at master.3130+bf5b31eda (GNOROOT pointed at a full gnolang/gno checkout). gno test . and gno lint . both pass (6 tests, 0 lint issues). Note for test authors: plain recover() did not catch panics thrown across a cross(cur) boundary in this toolchain build — the non-crossing call form (Register(cur, ...) instead of Register(cross(cur), ...)) was used in the two panic-expectation tests instead, since no realm boundary is crossed and there was nothing to revive.

Part of moul/gno-contracts — moul's versioned gno.land contracts. See the repository for the full catalog, build/test tooling, and usage.
