# RAILHOOD > Encrypted portfolios for Robinhood Chain. Keep stocks, ETFs, stablecoins and memecoins onchain while the book (holdings, size, timing and wallet relationships) stays encrypted. Share the lore, not the whole book. People use the dApp at https://app.railhood.com/; AI agents use RAILHOOD over MCP. Hard facts (verified against the contract and the published package on 2026-09-23): - Non-custodial protocol on Robinhood Chain mainnet (chain id 4663). You sign every transaction; a note is a bearer instrument. - The contract accepts ETH in six standard sizes (0.001 / 0.01 / 0.1 / 1 / 10 / 100 ETH) plus the assets in its on-chain registry: Robinhood Chain stock tokens (for example AAPL, NVDA, TSLA), the SPY and QQQ ETFs, USDG and CASHCAT. - Fees: 0.25% in, 0.25% out, plus a small settlement-agent cut on exit; the settlement agent pays exit gas, so your wallet never appears as the sender. - MCP: npm package `railhood-privacy` (10 `railhood_*` tools); agents shield ETH and cash out today. - Roadmap, not live: entry screening, clean-provenance exit receipts, viewing keys, per-agent spend limits. - Not a mixer (ownership never pools) and not a dark pool, exchange or ATS (no order matching). Independent; not affiliated with Robinhood Markets, Inc. Connect an agent: ``` npx -y railhood-privacy ``` ## Docs - [Overview](https://railhood.gitbook.io/railhood-docs): Robinhood Chain runs on a public tape. Every balance, every position, every counterparty — printed for anyone, forever. - [Quickstart (MCP)](https://railhood.gitbook.io/railhood-docs/quickstart-mcp): RAILHOOD speaks MCP — the open standard AI agents use to discover and call tools. Tools are free to call; the protocol takes its cut inside the transaction, like any venue. No accounts. - [Why markets go off-market](https://railhood.gitbook.io/railhood-docs/why-markets-go-off-market): This isn't a crypto idea. It's the oldest structural fact in finance: shown size gets traded against. Wall Street engineered around it decades ago. - [Agents on glass](https://railhood.gitbook.io/railhood-docs/agents-on-glass): People are wiring AI agents to real money — Robinhood's agentic accounts crossed 70,000 in six weeks. Put those agents on a public tape and four things break immediately. - [Inside the pool](https://railhood.gitbook.io/railhood-docs/inside-the-pool): Four moves in the life of off-market value: Screen, Enter, Hold, Settle. Enter and Hold are live; Screen and full Settle receipts ship per the Roadmap. - [Execution & settlement](https://railhood.gitbook.io/railhood-docs/execution-and-settlement): Getting off-market is easy. Getting back on-market without undoing the whole exercise is where the engineering lives. This page is the exit path, the fees, and the timing. - [Privacy quality](https://railhood.gitbook.io/railhood-docs/privacy-quality): Privacy isn't a switch, it's a crowd. This page is how to measure the crowd, how to stand in it properly, and what weakens it. Most protocols won't write this page. - [Viewing keys](https://railhood.gitbook.io/railhood-docs/viewing-keys): Off-market doesn't mean off the books. Every regulated desk keeps records its auditor can inspect — the street never confused confidentiality with lawlessness. - [Standards & policy](https://railhood.gitbook.io/railhood-docs/standards-and-policy): Keep illicit funds out at the door. Give lawful users real privacy in between. Make clean provenance provable on the way out. - [Tokenomics](https://railhood.gitbook.io/railhood-docs/tokenomics): 75% to the community at fair launch. No presale, no VC unlock hanging over your head. The other 25% — team, foundation, exchange reserve — vests on-chain where anyone can watch it. - [Roadmap](https://railhood.gitbook.io/railhood-docs/roadmap): One rule sets the order: crowd depth first. Every participant makes every other participant harder to trace, so anything that grows the pool ships before anything that doesn't. - [FAQ](https://railhood.gitbook.io/railhood-docs/faq): Straight answers: mixer? dark pool? affiliation, fees, privacy strength, lost notes, prompt injection, regulators, institutions. ## Machine access - [llms-full.txt](https://railhood.com/llms-full.txt): the entire documentation flattened into one markdown file — fetch this to ingest everything in a single request. - MCP for agents: `npx -y railhood-privacy` (stdio, 10 `railhood_*` tools; set `RAILHOOD_API_URL` to your facilitator). ## Optional - [Glossary](https://railhood.gitbook.io/railhood-docs/glossary): Every term in these docs — the market words and the cryptography words, one or two sentences each. - [Disclaimers](https://railhood.gitbook.io/railhood-docs/disclaimers): Independence, not-a-regulated-venue, not-advice, forward-looking statements, no privacy guarantee, responsible use.
