# RAILHOOD dApp

> The RAILHOOD web app at https://app.railhood.com/: shield ("go invisible") assets on Robinhood Chain into private notes that only your key can spend, then cash them out to your own or another wallet. Non-custodial: you sign every transaction. The app runs entirely in the browser; zero-knowledge proofs are generated client-side.

Facts (verified on-chain on 2026-09-26):
- Network: Robinhood Chain mainnet, chain id 4663. RAILHOOD contract (zkWrapper): 0x7cEfBBCDD18a98e17E8C6977F0485d61d512e3AF. A testnet (chain id 46630) can be selected in the app.
- Assets: 31 on mainnet — native ETH plus 30 registered tokens: Robinhood Chain stock tokens (for example AAPL, NVDA, TSLA, MSFT, AMZN), the SPY and QQQ ETFs, the USDG stablecoin and the CASHCAT community token (not affiliated with Robinhood).
- Standard sizes: every deposit uses a fixed denomination (for example 0.1, 1 or 10 shares of a stock token), so deposits look alike and the crowd stays private.
- Fees: 0.25% in, 0.25% out, plus a small settlement-agent cut on a gasless exit.

How the app works:
1. Go invisible: connect a wallet, pick an asset and a standard size, confirm. The deposit becomes a private note stored in this browser.
2. Cash out: pick a note. By default it pays out to the connected wallet. With "Send to another wallet", a settlement agent submits the payout to the address you enter and pays the gas, so your wallet never appears as the sender.
3. Manage notes: back up and restore notes. A note is a bearer instrument: whoever holds it can spend it, and a lost note cannot be recovered. Notes are stored per browser and per site.

For AI agents: RAILHOOD also works over MCP without this UI: `npx -y railhood-privacy` (see https://railhood.gitbook.io/railhood-docs/quickstart-mcp).
