3. #3# Linktree > ⚠️ **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](https://github.com/moul/gno-contracts/blob/main/r/moul/x/daily/README.md) --- A personal links page, one profile per address. Each caller owns their own profile: they set a bio and add or remove labeled links. Anyone can browse a profile at `/<address>`, and the root page lists every profile that exists with a link to each. Profiles are stored in an ordered AVL tree so rendering is deterministic. Realm path: `gno.land/r/REPLACE_ADDR/linktree` ## Example calls ``` # set your bio SetBio("Gnome builder, coffee enthusiast") # add links AddLink("Home", "https://example.com") AddLink("GitHub", "https://github.com/me") # remove the first link (0-indexed) RemoveLink(0) ``` ## Render - `Render("")` — index of all profiles, each linking to its page. - `Render("/g1abc...")` — that address's bio + links as a Markdown bullet list. <!-- BEGIN GNOCONTRACTS FOOTER (generated by `make readmes`; do not edit below) --> --- Part of **[moul/gno-contracts](https://github.com/moul/gno-contracts)** — moul's versioned gno.land contracts.
