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

Criterion	Weight	Source
Playable build	30%	Direct HTTP check of the official site plus hand-verified playability
Team visibility	15%	Attested in the registry
Liquidity depth	20%	DexScreener best pool
Holder spread	15%	Blockscout top-ten share, or estimated from holder count and marked as such
Ticker clarity	20%	Registry collision count; capped when no contract is attested

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

Data rules

Nothing is backfilled. A failed provider leaves the field null and marks the snapshot partial.
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.
Liveness is checked directly, one request per listing per refresh.
Every score carries its basis as a sentence next to the number.
Registry edits are dated and the registry is re-swept every four weeks.

Layout

apps/web            Next.js 15 site + /api/v1 route handlers
packages/core       registry, chain providers (viem RPC, Blockscout, DexScreener, liveness), screen, snapshot, economy store
packages/mcp        stdio MCP server over @greenwood/core
docs/               API, MCP, method, design notes
data/economy/       studio-reported economy reports (JSON, gitignored)

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

Variable	Default	Purpose
`GREENWOOD_RPC_URL`	public Robinhood RPC	Swap for Alchemy/QuickNode in production
`GREENWOOD_BLOCKSCOUT_URL`	`https://robinhoodchain.blockscout.com`	Explorer instance
`GREENWOOD_DATA_DIR`	`./data`	Where economy reports are stored
`GREENWOOD_INGEST_TOKEN`	unset	Enables `POST /api/v1/games/:id/economy` and the MCP submit tool
`NEXT_PUBLIC_SITE_URL`	`http://localhost:3210`	Canonical URL, OpenAPI servers

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.
