Crypto payment is one of the most compelling applications of blockchain and decentralized technologies. It enables permissionless, censorship-resistant transfer of assets across the globe. With zkTLS, crypto payment can be further simplified and abstracted away from wallet addresses. Instead of requiring a recipient’s wallet address, senders can specify a social account (e.g., email, Twitter, GitHub) as the payment destination. The recipient can later prove ownership of that account via zkTLS and securely claim the tokens into their own wallet. Developers can implement such a payment flow by:
  • Deploying smart contracts to manage payment records on-chain (from sender to recipient identity).
  • Mapping social accounts to verifiable claims using zkTLS proofs.
  • Allowing recipients to generate zero-knowledge proofs to withdraw assets to their preferred address.
User Benefits With zkTLS-based crypto payments, users no longer need to manage or disclose their wallet addresses. Instead, they can receive assets by simply proving ownership of an existing identity—such as a social account or email—without exposing sensitive information on-chain. This approach ensures end-to-end privacy, as the user’s identity remains completely hidden from the public ledger, reducing both privacy risks and friction in participation. The experience is seamless for both Web3-native users and those from traditional Web2 environments, making it significantly easier for anyone to access and benefit from crypto-based systems. By removing the technical complexity often associated with wallet management for newbies, this mechanism lowers the barrier to entry and creates a more intuitive, flexible, and inclusive way to send and receive crypto assets in a peer-to-peer manner.
