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.

Our architects design solutions that are scalable, secure, observable, and maintainable. We share the design with your engineers for review.
We build in bi-weekly sprints with working demos, automated testing, and code reviews. You see progress every two weeks, not at the end.
We roll out with zero-downtime strategies — blue-green, canary, feature flags — and a documented rollback plan for every release.
We hand over with full documentation and runbooks, then stay engaged for support, optimisation, and continuous improvement.
Tools and platforms we use day-to-day for PayTin. We are tool-agnostic — we pick what fits your stack.
Most engagements scope between 6 and 16 weeks depending on the size of your environment and the use-cases in scope. We share a phased plan with milestones during the discovery sprint, and we are explicit about what is included and what is not.
We support fixed-bid for well-scoped work, time-and-material for evolving work, and dedicated-squad for long-term partnerships. Pricing is based on team composition, duration, and delivery model — we share a transparent cost breakdown before commit.
Both. We can run delivery end-to-end with an accountable Ketpy squad, or we can embed senior engineers into your existing team. Many of our clients start with end-to-end and transition to a hybrid as their internal capability grows.
We are ISO 27001 certified with SOC 2 controls. We sign NDAs and DPAs upfront, follow least-privilege access by default, audit-log every action, and never offshore your data without written approval. For regulated industries we follow HIPAA, GDPR, RBI, and SEBI guidance as applicable.
Tell us what you are building and we will get back inside one business day with a written brief and a recommended next step.
