Hinkal has joined Mastercard’s Crypto Partner Program, bringing blockchain privacy infrastructure into a global payments initiative focused on digital assets. The partnership connects Hinkal with Mastercard’s ecosystem as stablecoins expand into payments, settlements, and commercial transactions.
Hinkal provides infrastructure that allows platforms to process private stablecoin transfers without exposing transaction amounts or counterparty relationships publicly. Its technology uses zero-knowledge proofs to verify transfers while keeping sensitive transaction details confidential.
The integration could help businesses explore onchain payments without making their financial activity visible to everyone on public blockchains.
Mastercard’s Crypto Partner Program connects blockchain companies with its payments teams and a broader network of industry participants. Members include stablecoin issuers, blockchain infrastructure providers, crypto card enablers and companies supporting digital asset transactions.
According to an announcement, the initiative supports practical digital asset applications through partner collaboration, industry connections and go-to-market opportunities. Selected members can also access financial institutions across Mastercard’s issuing and acquiring network, alongside regulatory and compliance support.
For Hinkal, joining the program creates an opportunity to bring confidential transaction infrastructure into payment products. Rather than requiring companies to build privacy systems independently, Hinkal allows wallets and platforms to integrate its technology through software development kits (SDKs) and APIs.
The infrastructure supports private settlements and payouts across fintech platforms, payment providers and wallets. Hinkal operates across Ethereum, Polygon, Solana, TRON and other major EVM-compatible networks.
Existing integrations demonstrate how the technology can fit into products already serving users.
Polygon Wallet offers Private Send powered by Hinkal, while Tether’s Wallet Development Kit includes its private-send functionality. Turnkey wallets can also integrate privacy through Hinkal’s SDK, and Avvio operates private payments through its interface.
These integrations allow partner platforms to maintain their products while adding transaction confidentiality as a feature.

Stablecoins can transfer value around the clock, but public blockchain transactions can expose financial relationships and payment amounts. That transparency may create challenges for businesses handling payroll, supplier payments, treasury movements and other commercially sensitive transactions.
Hinkal addresses this issue through zero-knowledge proofs, which allow a network to verify transfers without publicly revealing their underlying details. Its system keeps transaction amounts, senders and recipients confidential from public observers.
However, privacy does not mean eliminating compliance oversight. Hinkal says funds undergo screening before entering its system, while viewing keys allow users and businesses to share transaction histories with authorized auditors or regulators.
This approach aims to balance confidentiality with the oversight required for regulated financial activity. It could prove useful as payment providers explore stablecoins for cross-border transfers, business transactions and settlement flows.
Mastercard’s program provides a framework for connecting these technical capabilities with established payment infrastructure. However, Hinkal’s membership does not itself confirm a direct Mastercard product integration or a commercial launch.
