Greenwood

A game index for Robinhood Chain that ranks the build before it prices the token.

Robinhood Chain (chain id 4663) went live on 1 July 2026. Within weeks it had a gaming layer, and within weeks that layer was mostly tokens. Robinhood's own ecosystem directory has no games category. The one purpose-built hub that existed before this one advertised 42 games, surfaced ten, and displayed hardcoded prices on six of them, including a drained pool shown as the chain's busiest game.

Greenwood asks one question of every title: is this a game, or a ticker with art? It answers from live chain data, with every score carrying its written reason, and it refuses to show a number it cannot verify.

• Website — index, per-game screen breakdown, evidence, market and token panels, site liveness.

• REST API — the same JSON, with an OpenAPI 3.1 description and a studio economy ingest contract.

• MCP server — eight tools and one resource for Claude, Cursor and any MCP client, reading the chain directly.

The screen

Bands: sound ≥ 65, watch 45–64, avoid < 45. Pre-launch entries are unscreened. Full rules in docs/METHOD.md and on /method.

Related MCP server: robinscan-mcp

Data rules

1. Nothing is backfilled. A failed provider leaves the field null and marks the snapshot partial.

2. Contracts are attested, not matched. A token address enters the registry only when two independent sources agree. This chain carries six Senkai-named and four Thornveil-named ERC-20s.

3. Liveness is checked directly, one request per listing per refresh.

4. Every score carries its basis as a sentence next to the number.

5. Registry edits are dated and the registry is re-swept every four weeks.

Quick start

Requires Node 22.12+ and pnpm 10.

pnpm install
cp .env.example .env        # optional; defaults use the public RPC and explorer
pnpm sweep                  # prints what the chain says about every registry entry right now
pnpm dev                    # http://localhost:3210

Production:

pnpm build
pnpm start

MCP

pnpm --filter @greenwood/core build && pnpm --filter @greenwood/mcp build
claude mcp add greenwood -- node /absolute/path/to/greenwood/packages/mcp/dist/index.js

See docs/MCP.md for other clients and the tool list.

API

curl http://localhost:3210/api/v1/games/kindra
curl http://localhost:3210/api/v1/openapi.json

See docs/API.md, including the economy ingest contract.

Environment

Adding a game

Edit packages/core/src/registry.ts. Copy an entry, fill evidence with dated observations, leave tokenAddress null until two sources agree, then run pnpm sweep and pnpm test. Never resolve a contract by ticker.

Tests

pnpm test

Node's built-in runner over the compiled core. Covers registry integrity, band ordering, dead-site zeroing, pre-launch exclusion, partial flagging, ticker collisions and token-gate penalties.
