Tip Jar

⚠️ Experimental — generated with no human supervision by the daily MCP pipeline to exercise gno tooling. Not audited. See r/moul/x/daily.

A public tip jar realm: anyone can send real ugnot with an optional message via Tip, and the realm tracks a leaderboard of the most generous tippers plus a feed of recent tips, both rendered live in Markdown. Only the deployer (captured as owner at deploy time) can withdraw the accumulated balance. It's a small, complete example of the payment-guard pattern (OriginSend + IsUserCall) paired with a sorted avl.Tree leaderboard.

Built for gno 0.9.

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

Overview

Package tipjar is a public tip jar. Anyone can send real ugnot with an optional message via Tip; the realm keeps a running leaderboard of the most generous tippers and a feed of the most recent tips, both shown in Render. Only the deployer (captured as owner at init time) can Withdraw the accumulated balance. State-mutating functions are crossing functions (`cur realm`) per the gno 0.9 interrealm convention.

Functions 4

Action 
1func Balance() int64
source

Balance reports the ugnot still held by the jar (received minus withdrawn).

source

Render shows the jar's balance, the tipper leaderboard, and a feed of the most recent tips.

func Tip

crossing Action 
1func Tip(cur realm, message string) string
source

Tip credits the caller's OriginSend ugnot to the jar and records it against their running total. Only an EOA calling directly via MsgCall may tip — see the payment-guard note on IsUserCall vs IsUser.

func Withdraw
