Polygon Labs has added a “Privately Send” option to its consumer wallet, allowing users to send USDC and USDT as shielded payments on Polygon. The feature uses privacy tech from Hinkal so people can move stablecoins without revealing who they pay or how much they send on the public blockchain.
How Shielded USDC and USDT Payments Work
Instead of using a standard on-chain transaction, the new option sends transactions through Hinkal’s protected pool. The wallet conceals the sender, recipient, and amount when a user sends USDC or USDT privately, yet the network still confirms the transaction as legitimate.
Zero-knowledge proofs are used by Polygon and Hinkal to verify each payment, allowing observers to confirm that a genuine transfer occurred without linking it to a particular address or amount. When using the privacy function, customers retain direct control over their funds and do not transfer assets to a central operator, as the system remains non-custodial.
Why Polygon is Targeting Private Stablecoin Flows
Polygon Labs says this feature primarily targets institutional and business payments that have avoided public chains due to their perceived transparency. Many companies need to pay partners, staff, or suppliers without revealing every detail of their cash flows to competitors or on-chain data firms.
At the same time, the design adds Know Your Transaction (KYT) screening, which checks payments against risk and sanctions data before they move through the shielded pool. This mix of privacy and screening aims to make the product more acceptable to compliance teams that worry about fully anonymous tools.
Polygon has become one of the busiest networks for stablecoin activity, handling tens of millions of USDC and USDT transfers as people use it for remittances, payments, and trading. The chain focuses on fast finality and low fees, often settling payments in a few seconds for less than 1 cent, making it attractive for high‑frequency use.
Recent upgrades, such as bringing native USDC and Tether’s new USDT0 to Polygon, aim to deepen liquidity and make stablecoin flows smoother across chains. Shielded payments for USDC and USDT now sit on top of that stack, giving both everyday users and institutions a way to combine low‑cost transfers with stronger privacy when they move money on Polygon.
