Unigox Review 2026: Verified P2P Crypto-Fiat Ramp and API

Unigox is a crypto-fiat exchange that pulls together P2P merchants and centralized liquidity providers behind one interface. Users choose a currency, payment method and amount, and the system picks the best available ad instead of leaving them to browse offers.

The project positions itself as both a consumer wallet and an infrastructure provider. Its developer documentation describes partner-ready APIs for fiat-to-crypto and crypto-to-fiat flows across more than 40 local payment networks in Africa, Latin America, Asia and other regions. A wallet partner, Cosine Wallet, has integrated it as its fiat on/off-ramp.

The main selling point is trust reduction in P2P trades. Crypto sits in on-chain escrow, and bank transfers are verified with web proofs before release. The site says the team has over $12 billion in exchange volume and that the business is a Canadian MSB licensed business. Those are self-reported claims.

Unigox matches a user's request with the best offer across P2P merchants and centralized providers. A seller's crypto is locked in an on-chain escrow contract before the trade begins, so the buyer knows the funds exist.

The buyer then pays fiat by local bank transfer directly to the seller. To avoid the usual screenshot and manual confirmation steps, Unigox works with vlayer. The buyer logs into their bank inside an in-app browser, and vlayer produces a zero-knowledge web proof that the transfer happened, without exposing credentials. The Unigox backend uses that proof to release the crypto from escrow automatically.

For businesses, the same infrastructure is exposed as an API, hosted deep link or widget. Partners get order status through webhooks and can use stablecoin settlement across the supported corridors.

Unigox does not publish a full fee schedule in the material reviewed. One listing says the platform charges up to a stated percentage, but the exact figure and how it varies by corridor are not shown, so check the quote in the app before confirming a trade.

Users on the site describe withdrawals as fast with zero gas fees. For partners, the docs include a revenue share section, but the terms are not public. Payment-method costs, such as bank fees on your side, are separate and not covered.

Funds on the wallet side are described as non-custodial through Privy, and trades use an on-chain escrow contract built on Gnosis Safe with three signers: buyer, seller and Unigox. The site says the contract is audited, but the auditor and reports are not named in the material reviewed. Because Unigox is one of the signers, it plays a role in dispute resolution.

Unigox describes itself as a Canadian MSB licensed business. Users should confirm that its service is available and lawful in their own country. No security incidents are mentioned in the material reviewed. Bank-session verification adds reliance on a third-party proof provider, and users should handle their bank logins carefully.

Unigox is aimed at people who buy or sell stablecoins and other crypto through local bank transfers, especially in regions poorly served by card processors. It also suits wallet, fintech and payments developers who want to add on and off ramps through a widget or API rather than build local payment integrations themselves.
