No. Mixers pool coins and deal them back out. RAILHOOD seals each entry as a note only you can spend — ownership never pools, entries get screened, history stays provable on demand. Full mechanics in [Inside the pool](/railhood-docs/inside-the-pool.md). ### Is it a dark pool? Also no — and the distinction matters. Dark pools are regulated trading venues that match orders. RAILHOOD doesn't match anything; it's the settlement-privacy layer. Same instinct as the off-exchange world — don't print your hand — different machine entirely. ### Affiliated with Robinhood? No. Independent protocol on the permissionless Robinhood Chain network. Not affiliated with, endorsed by, or sponsored by Robinhood Markets, Inc. ### What can I take off-market? ETH, in six standard sizes from 0.001 to 100. Stablecoins are next on the [Roadmap](/railhood-docs/roadmap.md). ### What's the all-in cost? 0.25% in, 0.25% out, plus a small settlement-agent cut on exit in exchange for it paying your gas. MCP tools are free. That's the whole bill. ### Is it audited? SlowMist. The full report publishes separately — link lands here the day it's out. ### How private am I, really? As private as the crowd you're standing in. Run `pool_stats`, read the depth in your size, and stand in the crowd properly — the playbook is [Privacy quality](/railhood-docs/privacy-quality.md). We publish the number precisely so you can judge. ### What if I lose my note? Bearer instrument rules: lose it, lose the funds — and anyone who can read it can spend it. No recovery desk; that's what non-custodial means. Back it up like a private key, because it is one. ### What if my agent gets prompt-injected? Nothing stops the trick. Going off-market caps what the trick pays: the agent only reaches the float it holds, and the public trail from agent to treasury to you doesn't exist. Per-agent spend caps on the [Roadmap](/railhood-docs/roadmap.md) tighten it further. ### Do regulators hate this? Less than the timeline thinks. The U.S. Treasury told Congress in 2026 that lawful users have legitimate privacy needs on public blockchains, PETs are a national research priority, and regulators have overseen confidential execution in equities for decades. Receipts on [Standards & policy](/railhood-docs/standards-and-policy.md). ### Why would an institution touch this? Same reason they built the upstairs market: shown size gets traded against. The version they need — confidential against the crowd, provable to auditors — is exactly the viewing-keys-plus-receipts architecture. When the banks built their own chain, they built it private; the demand isn't hypothetical. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://railhood.gitbook.io/railhood-docs/faq.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
