Package leaderboard is an on-chain score leaderboard realm.
⚠️ 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
An on-chain score leaderboard realm for gno.land (sapphire / gno 0.9). Any account
can accumulate points with AddPoints(n) and optionally attach a display name
with SetName(name). Render returns a Markdown table ranked by points
descending — gold/silver/bronze medals for the top three — plus the total player
count. State is kept in an avl.Tree so rendering is deterministic across nodes.
Realm path: gno.land/r/REPLACE_ADDR/leaderboard
| Function | Kind | Description |
|---|---|---|
AddPoints(cur realm, n int) |
crossing (tx) | Add n (> 0) points to the caller's total. |
SetName(cur realm, name string) |
crossing (tx) | Set the caller's display name (≤ 32 bytes; empty clears it). |
Render(path string) string |
view | Ranked Markdown leaderboard. |

Package leaderboard is an on-chain score leaderboard realm.
Any account can accumulate points via AddPoints and (optionally) attach a display name with SetName. Render produces a ranked Markdown table sorted by points descending, with medals for the top three players.
AddPoints adds n points to the caller's total. n must be positive.
Crossing function: MsgCall dispatches only to crossing functions, and the cur.IsCurrent() check authenticates the live call frame before we trust the caller identity derived from it.
Render produces the Markdown leaderboard. It is NOT a crossing function (read-only view, no cur realm parameter).
SetName attaches a display name (max 32 bytes) to the caller. Passing an empty string clears the name and falls back to the address in Render.
