Microblog Wall

⚠️ 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 public, append-only microblog for gno.land. Anyone can post a short message (up to 280 bytes); each post records the caller's address and the block height at which it was made. The Render view shows the wall newest-first, 20 posts per page, with total count and prev/next pagination driven by the render path.

  • Realm path: gno.land/r/REPLACE_ADDR/microblog
  • Gno version: 0.9 (sapphire)

API

  • Post(cur realm, msg string) — crossing tx. Panics if msg is empty or longer than 280 bytes. Stores {author, msg, height}.
  • Count() int — total number of posts.
  • Render(path string) string — Markdown wall, newest-first, paginated.

Example calls

Post a message (crossing call via gnokey):

1gnokey maketx call \
2  -pkgpath "gno.land/r/REPLACE_ADDR/microblog" \
3  -func Post \
4  -args "gm gno.land 👋" \
5  -gas-fee 1000000ugnot -gas-wanted 2000000 \
6  -broadcast -chainid sapphire-1 -remote <rpc> mykey

View the wall in gnoweb:

https://gno.land/r/REPLACE_ADDR/microblog          # page 1 (newest 20)
https://gno.land/r/REPLACE_ADDR/microblog:?page=2  # older posts
https://gno.land/r/REPLACE_ADDR/microblog:/2       # same page, path form

From another realm:

1import "gno.land/r/REPLACE_ADDR/microblog"
