What is WalletConnect Pay

WalletConnect Pay enables payments providers and merchants to easily and compliantly accept stablecoin and crypto payments, providing low-cost, instant settlement payments with a single integration. Built on the WalletConnect Network, which powered over $400bn of transactions in 2025, WalletConnect Pay makes crypto payments available to over 500 million end users via its network of wallets across all blockchains. Ingenico is the first major payments leader to integrate WalletConnect Pay.

WalletConnect Pay Use Cases

WalletConnect Pay supports a wide range of payment scenarios across both online and offline environments:

• Merchants
  WalletConnect Pay helps merchants grow by connecting them to the largest global network of crypto users — a high-value, global audience that prefers to pay with crypto. Merchants can lower fees on all transactions and access funds faster through quicker settlement, all through their existing payment setup and without sacrificing operational reliability.

• End Users
  Customers pay with the crypto wallet they already trust, at the merchants they care about most — whether making everyday purchases, high-value transactions, or paying across borders. WalletConnect Pay makes the experience simple, familiar, and secure, with the freedom to use any asset, anywhere crypto makes sense. And with incentives like cashback built in, customers are rewarded for spending the way they already want to.

• Wallets
  Wallets integrate WalletConnect Pay to extend their users’ ability to pay in real-world contexts and unlock new, interchange-like revenue streams. Wallets retain full control of the user experience and branding, while WalletConnect Pay ensures seamless compatibility with existing PSP payment systems behind the scenes.

This expands the role of crypto beyond investment or on-chain activity, bringing it closer to everyday spending and real-world use cases.

WalletConnect Pay Support

WalletConnect Pay connects three core components: merchants, wallets, and blockchain assets. Merchants and DApps can integrate payment functionality through WalletConnect’s API or SDK, enabling users to pay directly with their crypto wallets. Wallets that support the WalletConnect protocol, such as CoolWallet, can enable WalletConnect Pay without requiring users to create additional accounts or give up custody of their assets.

In terms of asset and network support, WalletConnect Pay covers major blockchains and commonly used payment assets such as stablecoins. For the most up-to-date list, refer to the official WalletConnect Pay documentation. When choosing a wallet for payments, users should also consider which blockchains and tokens are supported by the wallet itself.

Future Vision

WalletConnect Pay aims not only to enhance the crypto payment experience, but also to accelerate the usability and adoption of Web3. As more wallets, DApps, and merchants join the ecosystem, payments will become increasingly seamless, approaching the intuitive experience users expect from Web2, and enabling crypto to fit naturally into everyday workflows.

At the same time, built in compliance mechanisms help bring crypto payments into the mainstream. Over time, WalletConnect Pay is set to become a key infrastructure layer connecting Web3 with the real world, moving crypto beyond investment and on-chain use cases into practical, everyday payments. When payments are simple, secure, and widely accessible, Web3 can truly scale to mass adoption.

FAQs

Q1. What is the difference between WalletConnect Pay and WalletConnect?

WalletConnect is a communication protocol that connects wallets with DApps, enabling users to interact with Web3 applications across devices and platforms. WalletConnect Pay builds on this foundation by adding a payment layer, allowing users to complete payments directly within DApps or at physical merchants.

Q2. Is WalletConnect Pay secure?

Yes. Especially when used with CoolWallet, private keys remain securely stored in a hardware wallet, and all transactions must be verified and signed by the user. This ensures that assets always remain under the user’s control and are never accessed by third parties.

Q3. Do I need KYC (Know Your Customer) to use WalletConnect Pay?

WalletConnect Pay aligns with global regulatory standards, but it does not follow a traditional KYC model. To comply with the Travel Rule, users may be required to provide basic identity information for certain transactions based on amount or jurisdiction. This process is designed within a decentralized framework, and the information is used solely for compliance purposes. CoolWallet does not access or store any personal data.

Q4. Which cryptocurrencies can I use for payments?

Supported assets depend on both the wallet and the merchant’s supported networks. In general, assets on major blockchains, especially stablecoins like USDC, are more commonly supported.

Currently, CoolWallet Pro, Go, and HOT support USDC on Ethereum, Base, Optimism, Polygon, and Arbitrum, while CoolWallet S supports USDC on Ethereum only.

Q5. Can WalletConnect Pay be used in physical stores?

Yes. Users can scan a merchant’s QR code to pay with crypto at supported locations, offering an experience similar to mobile payments.
