Add Buff Round-Up Investing Plugin

npm: buff-elizaos-plugin
GitHub: nightcode112/buff-elizaos-plugin (dedicated repo, package.json at root)

What it does

Auto-invests spare change from every agent transaction into crypto assets (BTC, ETH, SOL, USDC) via Jupiter on Solana.

Actions

Action	Description
BUFF_ROUNDUP	Record a round-up from any transaction

BUFF_SET_PLAN	Change round-up tier (seed/sprout/tree/forest)

Registry Update Checklist

• NPM package name matches the registry key (buff-elizaos-plugin)
• JSON is properly formatted
• Entry is alphabetically sorted among unscoped packages
• GitHub repo is publicly accessible
• package.json is at the repo root (dedicated repo, not monorepo)
• No duplicate entries or conflicting registrations
• Only index.json is modified

Note

This is a dedicated repo (not a monorepo subdirectory) — package.json is at the root for correct registry generation.

Buff elizaos joins the array,
In JSON's neat and tidy home,
One line added, now it can roam! ✨

🚥 Pre-merge checks | ✅ 3

✅ Passed checks (3 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title clearly and specifically identifies the main change: adding the buff-elizaos-plugin for round-up investing functionality.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Description check	✅ Passed	The pull request description is comprehensive and covers the essential details for a registry update. It includes the npm package name, GitHub repository link, clear explanation of plugin functionality, a detailed actions table, and a completed registry checklist addressing most key requirements (NPM name match, JSON formatting, alphabetical sorting, public accessibility, repo structure). However, the description does not explicitly verify all template requirements such as the presence of required images (logo.jpg, banner.jpg), elizaOS-plugins topic in GitHub settings, or agentConfig in package.json, which are important for official plugin submissions.

_{✏️ Tip: You can configure your own custom pre-merge checks in the settings.}

Updated the plugin to v1.0.0 — now uses server-side fee enforcement. The SDK is a thin API client with zero sensitive logic (no treasury addresses, no fee math, no swap routing). All enforced server-side at buff.finance.

• npm: buff-elizaos-plugin@1.0.0
• GitHub: https://github.com/nightcode112/buff-elizaos-plugin
• Added elizaos-plugins topic to the repo
