Privacy Infrastructure Hinkal Joins Mastercard Crypto Partner Program

Privacy infrastructure Hinkal announced on October 9, 2026, its participation in the Mastercard Crypto Partner Program. This program connects crypto and blockchain teams, Mastercard teams, and its global payment network, with members including stablecoin issuers, infrastructure providers, fiat exchange service providers, crypto card supporters, and blockchain and blockchain service providers. Mastercard positions it as a way to transform technological capabilities into compliant use cases for global commerce; some members can also access financial institutions within the card issuing and acquiring networks and receive regulatory and compliance support aligned with global standards.

Related use cases include cross-border payments and remittances, B2B transactions, fund and settlement flows, stablecoin payments, and card projects that allow users to spend digital assets at regular merchants. Hinkal can provide embeddable privacy capabilities for wallets, payment platforms, and chains, allowing stablecoins to settle in private balances and transfer using zero-knowledge proofs, ensuring that the amount, sender, or receiver is not disclosed during on-chain transfer verification. This capability is already live on Ethereum, Polygon, Solana, TRON, and other major EVM chains, accessible via SDK and API.

Existing integrations include Private Send in Polygon Wallet, Hinkal Private Send in the Tether wallet development kit, Turnkey wallets that can enhance privacy features through Hinkal SDK, and Avvio running Hinkal private payments on its own interface.
