Polygon has added a privacy layer to stablecoin transfers in its wallet, allowing users to send USDC and USDT without publicly revealing the sender, recipient, or amount.
The transfer still gets verified with zero-knowledge proofs through Hinkal, and Polygon says every private transaction is run through KYT screening before it goes through.
The company is framing the feature as a way to give institutions confidentiality onchain without turning regulators blind to the flow.
The sharper angle here is that Polygon is aiming this less at casual users than at treasury teams, payroll systems, and other business flows that have stayed off public chains because every payment is visible to everyone.
The blockchain company says that exposure is a major reason serious stablecoin activity still sits offchain, while Hinkal says users can generate audit files for regulators and tax authorities, which makes the setup look like privacy with a compliance trail rather than privacy as concealment.
The launch also fits the blockchain company’s wider push to position itself as a payments rail through its Open Money Stack.
On the same announcement, Polygon said the new flow is designed to preserve the speed and cost of onchain settlement while adding the confidentiality that traditional rails already provide.
Funds also do not pass into Hinkal’s custody during transfer, which keeps the design non-custodial.
That bet arrives at a time when Polygon already has meaningful stablecoin activity. DeFiLlama currently shows Polygon’s stablecoin market cap at about $3.586 billion, which keeps it among the larger chains for stablecoin supply.
Inference: Polygon is trying to turn that liquidity into institutional payment volume by solving the one issue public blockchains still struggle with most: confidentiality.
