Web3 payment gateway supporting cryptocurrency and multi-chain transactions.
PayTin is a next-generation Web3 payment gateway that lets merchants accept cryptocurrency and stablecoin payments from customers around the world as easily as they accept card payments. Merchants integrate once via REST APIs, SDKs, or WordPress/Shopify plugins and can instantly accept USDT, USDC, DAI, BTC, ETH, MATIC, SOL, BNB, and 30+ other tokens across Ethereum, Polygon, Solana, Arbitrum, Optimism, Base, BNB Chain, and Tron. PayTin auto-converts crypto payments into the merchant's preferred fiat (INR, USD, EUR, AED, SGD) or stablecoin at competitive rates, removing volatility risk and simplifying accounting. The platform has processed over 3 billion USD in gross transaction volume with a 99.98% success rate.
Under the hood, PayTin combines deep blockchain engineering with institutional compliance. Multi-chain wallet infrastructure uses MPC (multi-party computation) and HSM-backed key management for merchant funds, with no single point of compromise. Real-time exchange routing taps liquidity from top CEXs and DEXs to give merchants best execution. AML and sanctions screening (Chainalysis, TRM Labs) runs on every transaction, flagging mixer-tainted addresses, OFAC-listed wallets, and high-risk jurisdictions. Merchants get a polished dashboard with transaction history, invoices, recurring billing, refunds, payouts, and a developer console with webhooks and test-mode. Consumer-facing checkout flows are mobile-first, support WalletConnect v2, MetaMask, Phantom, Coinbase Wallet, and QR-based mobile payments. PayTin also offers non-custodial settlement for merchants who prefer to receive crypto directly to their own wallets.

Tools and platforms we use day-to-day for PayTin. We are tool-agnostic — we pick what fits your stack.
Regulatory status varies by jurisdiction. PayTin is currently used by merchants in EU, UK, UAE, Singapore, and select US states where crypto acceptance is permitted. In India, business acceptance is nuanced (RBI + Income Tax) — talk to your CA. PayTin auto-generates compliant reports for any jurisdiction.
As simple as any card processor. Drop in our JS SDK / WordPress / Shopify plugin in under an hour, or use REST APIs for custom flows. Your customer sees a familiar hosted checkout, pays with their wallet, you get an INR/USD credit — you never touch tokens if you do not want to.
No. When a customer initiates payment, PayTin locks the exchange rate for 20 minutes via real-time CEX + DEX routing. Once the txn confirms on-chain, we credit your fiat balance at the locked rate. You bear zero volatility.
Merchant funds sit in MPC (multi-party computation) wallets with HSM-backed key shares — no single point of compromise. Cold storage for balances above configurable thresholds, insurance coverage for hot wallets, and regular third-party pen-tests. Or use non-custodial mode and receive crypto directly to your wallet.
Chainalysis + TRM Labs run signatures on the sending wallet in under 300ms — legit transactions clear instantly. Only mixer-tainted, OFAC-listed, or sanctioned addresses get held for review. False-positive rate is under 0.3% for retail transactions.
