Powering Private Stablecoin Payments on Polygon

Last week, through a series of partnership announcements, Polygon put Meta, Visa, and Modern Treasury on stage - three of the biggest names in payouts, card settlement, and financial infrastructure.

Today, Polygon shipped the missing piece those institutions and enterprises need to scale their stablecoin operations.

Private stablecoin payments on Polygon - powered exclusively by Hinkal.

Inside Polygon Wallet, with no change to existing workflows, compliance controls, or custody, users can now send USDC and USDT privately. Sender, amount, and counterparty relationships stay fully confidential on-chain.

We are proud to power the first user-facing privacy capability at the wallet layer of a major L2 - built directly into the wallet institutions already use.

What Hinkal Unlocks On Polygon

Private stablecoin payments inside Polygon Wallet - and across every embedded wallet flow, pay-in, and payout built on the Polygon Open Money Stack.

Without privacy, every USDC and USDT transfer a fintech, payments platform, or enterprise app makes on Polygon publicly exposes:

  • The sending wallet
  • The receiving wallet
  • The amount
  • The timing
  • The relationship between counterparties

That data is broadcast in real time, to every observer, permanently.

This is real operational risk. Enterprises do not want vendor payments, treasury movements, payout schedules, or business relationships visible to competitors and counterparties as they happen. Competitors derive pricing intelligence. Counterparties derive negotiating leverage. Markets derive trading signals.

With Hinkal integrated into Polygon Wallet, those same stablecoin flows can now move privately. The transaction still settles on Polygon. It remains verifiable on-chain. The sensitive details - sender, amount, recipient, and the relationships between them - are not publicly exposed.

This is the practical value of the integration: stablecoins keep what makes them work - speed, global reach, programmability, 24/7 settlement - while gaining the TradFi-grade confidentiality businesses are used to and expect from any financial infrastructure.

Why Hinkal

Hinkal architecture is the only one that clears the institutional bar across every dimension that matters:

Full transaction graph confidentiality. Sender, amount, and recipient are all hidden on-chain. Competitors and counterparties cannot derive the data that standard on-chain transfers leak by default. The transaction graph itself - who moved what to whom - is unobservable.

Cryptographic verifiability. Every private transfer is verified on-chain via zero-knowledge proofs. Confidential to the public. Provably valid to the network. No trust required.

Compliance by design. Every private transaction is screened via Chainalysis KYT before execution. Privacy from the market - not from regulators.

Non-custodial. Funds move directly between wallets through the protocol. Hinkal never takes custody. No operator, no intermediary, no third party holds the assets at any point in the transfer.

Zero workflow disruption. Users do not change their behavior. Same wallet, same UX, same compliance perimeter - with privacy enabled in a single click. The sender sends as they would have sent before, from the wallet they were using before. No new app to learn, no new key to manage, no retraining for treasury or operations teams.

Instant processing. Hinkal clears private transfers faster than any comparable privacy solution on the market today. Speed is non-negotiable when stablecoin flows run at enterprise volume.

How It Works

Inside wallet.polygon.technology, users now see a privacy option alongside the standard send flow.

Selecting it routes the transfer through Hinkal's shielded pool. Chainalysis KYT screens the transaction before execution. A zero-knowledge proof verifies it and funds move directly between sender and receiver wallets through the protocol - no exchange or intermediary is involved.

Outside observers can verify that a valid transfer occurred on Polygon. They cannot see who sent it, who received it, or how much moved. Sender and receiver are not linkable on-chain.

The user experience is identical to a standard send. 

Privacy is default.

The Next Phase Of Stablecoin Payments Is Confidential

Polygon is building the infrastructure for money to move on-chain across wallets, applications, and institutions. Hinkal is the privacy that makes those flows usable for real business activity.

Private stablecoin payments on Polygon is not a feature launch. This is a foundation - the first user-facing privacy primitive in what becomes the institutional standard for stablecoin movement on-chain.

For users, this means private USDC and USDT transfers inside Polygon Wallet, with no change to how they already use it.

For applications and developers, it means privacy as part of the payment stack itself - not an external add-on.

For institutions and enterprises, it means public-chain settlement that finally looks like real financial infrastructure:

Fast. Verifiable. Compliant. Confidential.

Private stablecoin payments are now live on Polygon, powered by Hinkal.
