In the world of no-KYC Bitcoin exchanges, speed and privacy have traditionally been opposing forces.
You could have privacy through on-chain P2P trades, but you'd wait hours for confirmations. You could have speed through centralized exchanges, but you'd sacrifice your identity and sovereignty. RoboSats said "screw that" and built something different: a Lightning-native P2P exchange where trades settle in minutes, privacy is baked into the DNA, and your robot avatar is literally your only identity.
Welcome to the future of private Bitcoin trading.
What is RoboSats?
RoboSats is an open-source, Tor-only peer-to-peer exchange that lets you trade Bitcoin for fiat currencies using the Lightning Network. Unlike traditional P2P platforms that rely on on-chain multisig and sluggish block confirmations, RoboSats leverages Lightning hold invoices to create instant, minimally custodial escrow. The result? Trades that complete in as little as 5-8 minutes with near-zero fees.
But here's where it gets cool: you don't create an account. You don't provide an email. You don't even pick a username. Instead, RoboSats generates a random robot avatar for you based on a token—think of it as a temporary, pseudonymous identity that exists only for your trades. Want a new identity? Generate a new token. Want to recover your reputation? Keep your token safe. It's privacy by design, not privacy as an afterthought.
The platform is accessible via Tor Browser, an Android app, or even self-hosted on your own node through Umbrel, Citadel, or Start9.
Every interaction happens over Tor hidden services by default, ensuring your IP address never touches the platform. Your trading partner is the only person who might learn anything about you—and even then, only what's necessary to complete the fiat payment.
Origin and Creation Context
RoboSats burst onto the scene in February 2022, launched by the pseudonymous developer known as "Reckless Satoshi"—a fitting name for someone building recklessly innovative Bitcoin infrastructure. The project was inspired by P2PLNBot (created by @grunch), another Lightning-based P2P bot, but Reckless Satoshi saw an opportunity to simplify the UX and make private, Lightning-native trading accessible to normal humans, not just terminal-dwelling cypherpunks.
The timing was perfect. By early 2022, the Bitcoin community was increasingly aware of KYC's dangers—data breaches, government overreach, social credit systems, and the weaponization of financial surveillance. Centralized exchanges were collecting absurd amounts of personal data (selfies, ID scans, proof of address), and we all knew it was only a matter of time before that data got leaked, hacked, or handed over to whoever asked for it.
Meanwhile, existing P2P solutions like Bisq, while philosophically aligned, required on-chain transactions that took hours and cost real money in miner fees. For smaller trades—the kind everyday people make—this was overkill.
RoboSats filled that gap: Lightning-fast, Lightning-cheap, and Lightning-native. By leveraging Lightning hold invoices as fidelity bonds and trade escrow, RoboSats minimized custody requirements while maximizing speed.
The project remains fully open-source and community-driven, released under the AGPL 3.0 license. Development happens in public on GitHub, with contributions from developers worldwide.
In 2023, RoboSats evolved into a federated model, allowing multiple independent coordinators to operate simultaneously—further decentralizing the network and making it even harder to shut down or censor.
Why Privacy Advocates Choose RoboSats
RoboSats isn't just another exchange. It's a statement that you can have speed AND privacy, convenience AND sovereignty. Here's why people who give a damn about financial freedom love it:
Zero KYC, Always
RoboSats will never—ever—ask for your real name, email, phone number, country, ID, or any other piece of personally identifiable information. The platform literally cannot ask for what it doesn't collect. Your robot avatar is your identity. That's it. No registration, no account approval, no waiting period. Just generate your robot and start trading.
Lightning-Speed Trades
The average RoboSats trade completes in about 8 minutes. Compare that to Bisq's multi-hour on-chain settlements or centralized exchanges' withdrawal delays. Lightning settlements are instant once both parties confirm—no waiting for blockchain confirmations, no staring at mempool explorers praying your transaction goes through. When the seller confirms they received your fiat, the sats hit your Lightning wallet immediately.
Minimal Custody
RoboSats uses Lightning hold invoices (also called hodl invoices) for both fidelity bonds and trade escrow. These invoices freeze funds in your wallet without actually transferring custody to RoboSats. The platform can't steal your sats—it can only release or return them based on the trade outcome. This custody-minimized approach means you're never trusting RoboSats with your funds the way you'd trust a centralized exchange.
Tor-Only Access
RoboSats is designed from the ground up to be accessed via Tor. While there's technically an "unsafe" clearnet URL for browsing the order book, you can't actually trade through it—critical features like the P2P chat are disabled. This forces users into good privacy hygiene. Your IP address never connects directly to RoboSats. Every interaction is routed through Tor's onion network, making traffic analysis and location tracking exponentially harder.
Ephemeral Identities
Your robot avatar is generated deterministically from a random token. Same token = same robot. Different token = different robot. This means you can create a fresh identity for every trade if you want maximum privacy, or reuse the same robot to build reputation. The choice is yours. RoboSats doesn't force identity persistence—it enables it as an option. This is privacy done right: giving users control without sacrificing functionality.
End-to-End Encrypted Chat
All communication between trading partners happens through PGP-encrypted chat. RoboSats coordinators can't read your messages. They see encrypted gibberish. Only you and your trading partner hold the keys to decrypt the conversation. This matters because fiat payment details (bank accounts, Venmo handles, cash meeting locations) flow through this chat—information that could be used to dox you if intercepted.
Federated Architecture
As of version 0.6.0, RoboSats operates as a federation of independent coordinators. Multiple backend instances run simultaneously, and the client app connects to all of them. This spreads liquidity, improves censorship resistance, and eliminates single points of failure. If one coordinator gets shut down or goes rogue, the others keep running. You can even run your own coordinator if you're technically inclined.
Advantages
- Lightning Fast: Trades complete in 5-8 minutes on average. No waiting for on-chain confirmations.
- Minimal Fees: Lightning routing fees are negligible—often a few sats. No expensive on-chain transaction costs.
- Maximum Privacy: Tor-only access, ephemeral robot identities, encrypted P2P chat, and zero data collection.
- No Registration: Generate a robot and start trading immediately. No email, no phone, no verification.
- Minimal Custody: Lightning hold invoices freeze funds in your wallet. RoboSats never has full custody of your sats.
- Global Payment Methods: Supports 60+ fiat currencies and virtually any payment method peers agree on.
- Self-Hosting Options: Run RoboSats on your own Umbrel, Citadel, or Start9 node for maximum sovereignty.
- Mobile & Desktop Apps: Native Android app and web interface accessible via Tor Browser.
- Face-to-Face Trading: Supports in-person cash trades with location-based matching (with privacy-preserving location fuzzing).
- Open Source & Federated: Fully transparent code and multiple independent coordinators eliminate single points of failure.
Disadvantages
- Lightning Required: You need a Lightning wallet with hold invoice support. Not all Lightning wallets work. Phoenix and Zeus are recommended.
Nakamoto Builder
- Small Trade Limits: Maximum trade size is typically around 4-5 million sats due to Lightning routing constraints. Great for stacking, not for whales.
- Bootstrap Problem: You need a small amount of Lightning sats upfront (~3% of trade amount) for the fidelity bond. First-time buyers face a chicken-and-egg issue.
- Experimental Technology: RoboSats is still considered alpha software. While it works well, bugs and edge cases exist.
- Liquidity Limitations: Order book can be thin for less common fiat currencies and payment methods. USD and EUR dominate.
- Trust in Coordinators: While minimal custody, coordinators still handle dispute resolution. Federation model mitigates this risk but doesn't eliminate it.
- No iOS App: Currently Android-only for mobile. iOS users must use Tor Browser or Onion Browser workarounds.
- Lightning Complexity: Understanding Lightning channels, liquidity, and routing adds friction for complete beginners.

Getting Started: Mini Tutorial
Here's how to make your first RoboSats trade:
Prerequisites
Lightning Wallet: You need a Lightning wallet that supports hold invoices. Recommended: Phoenix (mobile, no node required) or Zeus (if you run a node).
- Small Amount of Sats: You'll need ~3% of your trade amount for the fidelity bond. If buying 100,000 sats, you need ~3,000 sats upfront.
- Tor Browser: Download Tor Browser from torproject.org. Android users can use the RoboSats APK from GitHub or Orbot + browser.
Accessing RoboSats
- Open Tor Browser and visit: robosats.com (this redirects to the .onion hidden service).
- Alternative: Direct .onion URL: robosatsy56bwqn56qyadmcxkx767hnabg4mihxlmgyt6if5gnuxvzad.onion
- On first visit, RoboSats generates a random robot avatar and token. Save this token somewhere safe (password manager, encrypted notes). You'll need it to recover your robot and reputation.
Taking a Buy Order (Buying Bitcoin)
- Click Book to browse available orders.
- Filter by your currency (USD, EUR, etc.) and payment method (bank transfer, Venmo, cash, etc.).
- Look at the premium percentage and trade size. A 2-5% premium is normal for small private trades.
- Click an order you like, review the details, and click Take Order.
- Lock Your Fidelity Bond: RoboSats generates a Lightning invoice for your bond (~3% of trade amount). Scan it with your Lightning wallet. The sats freeze—they don't leave your wallet yet. They're only charged if you cheat or cancel unilaterally.
- Wait for Seller to Lock: The seller locks their trade collateral using a hold invoice. Once locked, you'll see it in the contract.
- Submit Payout Invoice: Generate a Lightning invoice in your wallet for the amount of sats you're buying. Paste it into RoboSats.
- Chat with Seller: The encrypted chat opens. Say hi! The seller will provide their payment details (bank account, Venmo handle, etc.).
- Send Fiat Payment: Send the fiat through the agreed method. Bank transfer, cash app, whatever. Keep proof of payment.
- Confirm Payment Sent: Click Confirm Fiat Sent in RoboSats.
- Wait for Seller Confirmation: Seller checks their bank/payment app and confirms receipt.
- Lightning Zap! Once seller confirms, RoboSats releases the sats to your Lightning invoice. They hit your wallet instantly. Your bond unlocks and returns automatically.
Boom. You just bought Bitcoin privately in under 10 minutes.
Creating a Sell Order (Selling Bitcoin)
- Click Create to make a new order.
- Select SELL order type.
- Choose your currency, payment method, and trade amount.
- Set your premium (how much above market price you're willing to accept). Consider 2-8% for privacy premium.
- Lock Maker Bond: Pay the fidelity bond invoice to publish your order.
- Wait for Taker: When someone takes your order, you'll be notified.
- Lock Trade Collateral: Pay the hold invoice for the sats you're selling.
- Send Payment Details: In the encrypted chat, tell the buyer where to send fiat.
- Wait for Payment: Buyer sends fiat. Check your bank/payment app.
- Confirm Receipt: Once fiat lands, click confirm. RoboSats releases sats to buyer, your bond returns.
Pro Tips
- Start Small: First few trades? Keep amounts under 100,000 sats while you learn the flow.
- Be Online: Both parties need to be responsive. If someone's offline (red dot on avatar), trade might take longer.
- Multiple Robots: Want to do multiple trades at once? Generate new robot tokens. Each robot can have one active order.
- Payment Method Matters: Instant methods (Venmo, CashApp) = faster trades. Bank transfers = slower but more common.
- Self-Host If You Can: Running RoboSats on your own Umbrel/Start9 node = maximum sovereignty and faster load times.
Final Assessment
RoboSats is what happens when you take Bitcoin's Lightning Network and actually build something useful with it. Not another speculative token. Not another DeFi casino. A real tool for real people who want to buy and sell Bitcoin privately, quickly, and cheaply. It's the spiritual successor to LocalBitcoins before that platform disappeared.
The beauty of RoboSats is its simplicity. Generate a robot. Browse orders. Take one. Send fiat. Receive sats. The entire flow is intuitive enough for normies but maintains the privacy standards demanded by cypherpunks. That's a rare balance. Most privacy tools are either too complex (Bisq's learning curve) or too compromised (centralized exchanges with "privacy" theater).
The Lightning-native approach is brilliant. By leveraging hold invoices, RoboSats achieves near-instant settlement without full custody. The sats freeze in your wallet during the trade—they never actually leave your control the way they would on a centralized exchange. If the trade goes south, your bond gets charged. If it goes well, everything unlocks. Simple game theory enforced by Lightning's native features.
But RoboSats isn't perfect. The trade size limits are real constraints. Lightning routing struggles with large payments, so you're capped at a few million sats per trade. This makes RoboSats ideal for stacking (regular small buys) but terrible for whales looking to move serious weight. For large trades, Bisq's on-chain multisig remains the better option despite the slower speed.
The bootstrap problem is also annoying. You need Lightning sats before you can buy Lightning sats. First-time users have to acquire that initial bond amount elsewhere—maybe from a Bitcoin ATM, a friend, or a KYC exchange (yuck). Once you've got that first bit of Lightning liquidity though, you can cycle between buying more and spending, staying entirely outside the KYC system.
RoboSats represents the future of private Bitcoin acquisition for normal people. It's fast enough to compete with centralized exchanges. It's cheap enough that fees don't matter. It's private enough that you're not doxxing yourself to the world. And it's simple enough that you don't need a PhD in computer science to use it.
The revolution won't be KYC'd. RoboSats is proof. While centralized exchanges race to become regulated banks cosplaying as crypto platforms, RoboSats went the opposite direction: doubling down on privacy, speed, and user sovereignty. It's serving a market that centralized platforms abandoned—people who just want to buy and sell Bitcoin privately without asking permission from anyone.
If you're already on Lightning, there's zero excuse not to try RoboSats. Generate a robot avatar. Take an order. Experience what trading looks like when you're not the product. It's not just faster and cheaper—it's fundamentally different. You're not a customer being surveilled. You're a peer engaging in voluntary exchange. That's the Bitcoin ethos in action.
For anyone serious about Bitcoin privacy and tired of on-chain's molasses-speed trades, RoboSats is where you should be stacking. Lightning fast. Lightning cheap. Maximum privacy. That's the future—and it's already here, hiding behind robot avatars in Tor's dark corners.
Who Should Use RoboSats?
RoboSats is perfect for:
- Regular stackers making small-to-medium purchases (under $2-3k)
- Privacy-conscious individuals who refuse KYC
- Lightning Network users who already understand the basics
- People in countries with capital controls or hostile crypto regulations
- Anyone who values speed and doesn't want to wait hours for on-chain confirmations
RoboSats might not work for:
- Complete Bitcoin beginners with zero Lightning knowledge
- Whales needing to move large amounts (>$2-3k per trade)
- People without access to an initial Lightning bond amount
- Those who prioritize absolute decentralization over speed (use Bisq instead)
