Privacy infrastructure provider Hinkal said on Oct. 9, 2026 that it has joined Mastercard’s crypto partner program, a network designed to connect crypto and blockchain teams with Mastercard and its global payments rails. The program includes stablecoin issuers and infrastructure providers, fiat on- and off-ramp services, crypto card enablers, and blockchain and blockchain service providers.
Mastercard describes the initiative as a way to turn technical capabilities into compliant use cases that can operate in global commerce. Some participants may also gain access to financial institutions in issuing and acquiring networks, along with regulatory and compliance support aligned with global standards. Use cases named in the announcement include cross-border payments and remittances, B2B transactions, money movement and settlement flows, stablecoin payments, and card programs that let users spend digital assets at everyday merchants.
Hinkal said its product can add embedded privacy features to wallets, payment platforms, and blockchains. It supports stablecoin settlement in private balances and uses zero-knowledge proofs to move funds without exposing the amount, sender, or recipient during on-chain verification. The company said the capability is live on Ethereum, Polygon, Solana, TRON, and other major EVM chains, with access available through SDKs and APIs. Existing integrations include Polygon Wallet’s Private Send, Hinkal private send in the Tether Wallet Development Kit, Turnkey wallets using the Hinkal SDK for privacy features, and Avvio running Hinkal private payments in its own interface.
