OK Exchange

OK Exchange is an Iranian cryptocurrency exchange platform that has operated since 2017, offering spot and futures trading, over-the-counter (OTC) swaps, and a multi-asset digital wallet to users in Iran. Founded in October 2017, OK Exchange reports over two million registered users and self-describes as a knowledge-based enterprise operating out of Tehran, serving Farsi-speaking traders through a Farsi-language interface. Iran retail crypto market has developed in isolation from global platforms because major international exchanges explicitly restrict services to Iranian users under sanctions compliance programs. OK Exchange is among the platforms that emerged to fill that gap, enabling Iranian residents to buy, sell, and trade digital assets using local payment rails and fiat currency denominated in Iranian rial. The platform offers three primary trading modes: a spot market with standard cryptocurrency-to-cryptocurrency and fiat-to-crypto trading across more than 700 digital assets including Bitcoin (BTC), Ethereum (ETH), Tether (USDT), Solana (SOL), Dogecoin (DOGE), Tron (TRX), BNB, XRP, and Cardano (ADA); futures contracts with up to 150x leverage targeting active traders; and a quick exchange OTC interface for simplified asset conversion without navigating an order book. Users access all three modes through a single account, with fiat deposits accepted in toman starting from 10,000 toman. OK Exchange includes a built-in multi-asset digital wallet supporting custody for over 700 cryptocurrencies, free deposits and withdrawals, and real-time fund transfers. The exchange requires two-factor authentication (2FA) on user accounts and claims cold wallet storage for a portion of user funds. Mandatory KYC at account opening is tailored to Iranian ID documentation requirements. For developers, OK Exchange operates a documentation portal at docs.ok-ex.io with a REST API providing access to market data and account management functions; a WebSocket API for real-time streaming is listed as coming soon. Solana (SOL) is among the assets available for spot trading and wallet custody on OK Exchange, giving Iranian users one of the available domestic options to buy, sell, and hold SOL. The exchange maintains an active blog publishing daily price analysis and educational content in Farsi, an affiliate program offering 30 percent commission on referred trading activity, 24/7 customer support, and an X presence at @okexir. With over two million reported users and more than eight years of continuous operation, OK Exchange is one of the longer-standing domestic crypto venues in Iran, with coverage spanning major tokens, DeFi assets, meme coins, and Solana-ecosystem tokens.
