Onchain escrow security
Trust guaranteed by code, not by promises.
Unlike an exchange, you never deposit your money with Vailox. Everything settles onchain, transparently and verifiably.
- Onchain escrow
- The seller's crypto is held in a smart contract until both parties deliver. Neither Vailox nor anyone else can touch it outside the agreed terms.
- Real-time chat
- Talk to the other party without leaving the order and share payment proof instantly.
- Verified reputation
- Every completed trade adds real reviews. Choose who to trade with based on their track record.
- Your keys, your funds
- You trade with your own wallet. No mandatory KYC; email is optional, only for notifications.
- Mediated disputes
- If something goes wrong, either party can open a dispute and the team mediates based on the evidence.
Smart contract audit
An audited smart contract, not a leap of faith.
Every trade's funds depend on the escrow contract, so we treat it as the most important part of Vailox.
- Audited, proven base
- We started from an open-source contract already audited by a security firm and battle-tested for years.
- Minimal changes
- Only minimal, targeted changes to optimize it, without touching its underlying structure.
- Re-audited by HelixNebula
- The final code has been audited again by the cybersecurity firm HelixNebula.

A decentralized P2P platform to buy and sell crypto. We connect buyers and sellers directly and protect every trade with a blockchain escrow, with no centralized intermediaries.
A group of traders who started out in P2P and kept running into the same problems: weak security, custody in someone else's hands and platforms not built for people who actually trade. That's why we built Vailox, by traders for traders, focused on security, self-custody and onchain escrow.
No. You trade with the other party. Vailox lists the offers and provides the onchain escrow where the seller's crypto is held. We only step in if a dispute is opened.
When a trade starts, the seller's crypto is locked in a smart contract. The buyer sends the fiat payment and, once the seller confirms receipt, the contract automatically releases the crypto to the buyer. The contract owner cannot touch locked funds: they can only step in if one party opens a dispute, and even then they can only release them to the buyer or the seller according to the resolution.
We built the contract on an open-source codebase already audited by a reputable security firm and proven over years. We only made minimal, targeted changes to optimize it without changing its structure, and the final code has been audited again by the cybersecurity firm HelixNebula.
No. Just connect your wallet, hot or cold. If you want, you can link an email to get notifications or recover access, but it's optional. Trust is built through the reputation system of verified trades.
For now, the USDT and USDC stablecoins. We're working on adding more cryptocurrencies.
More than 20, depending on the currency: bank transfer, SEPA Instant, Bizum, Revolut, Wise, N26, PayPal, Zelle, MercadoPago, Pago Móvil, in-person cash through Cash Points and many more. Each seller chooses which methods their offers accept.
Euros (EUR), US dollars (USD), Argentine pesos (ARS) and Venezuelan bolívares (VES). Each offer shows its currency and available payment methods.
Ethereum, Polygon, Arbitrum, Base, BNB Chain and Tron. A single offer can accept several networks at once.
Yes. Before the seller locks the funds, either party can cancel without penalty. Once the funds are in escrow, the buyer can cancel as long as they haven't marked the payment as sent.
Either party can open a dispute. The team reviews the evidence from both sides and resolves it fairly; the escrowed funds are released according to the outcome.
Vailox charges a transparent fee per trade that is always shown before you confirm the order. No hidden charges. Remember to keep some gas on the chosen network.
You can create private offers (shared via link) from day one. To publish public offers on the marketplace you need at least 5 successfully completed trades.
