Polygon (POL) has launched private stablecoin payments through its consumer wallet, looking to draw institutions onto the chain with shielded transfers for USDC (usdc) and USDT (usdt).
Shielded Pool Launch
The Ethereum layer-2 rolled out the feature on Monday in a partnership with privacy protocol Hinkal.
Users selecting the new "Privately Send" option route their stablecoins through a Hinkal shielded pool. Sender, receiver, and transfer amount stay hidden from public view.
Outside observers can still confirm a valid transfer occurred. They cannot see who participated or how much moved.
Verification is handled by zero-knowledge proofs. The protocol is non-custodial, meaning no operator holds user assets during a transfer.

Compliance Pitch
Polygon framed the launch as a play for institutional flows that have stayed off public chains over transparency concerns. Privacy here means opacity to the market, not to regulators, the team said.
Every private transaction passes through Know Your Transaction screening before execution. Hinkal's documentation also lets users generate audit files for tax officials.
Polygon community lead Smokey wrote on X that businesses need operational privacy, not the kind that hides activity from regulators. Banks, treasuries, and payments teams already operate that way on traditional rails, the company argued.
The launch sits inside Polygon's broader Open Money Stack push. That program has produced a Visa settlement integration and a Meta deal to use USDC for creator payouts in Colombia and the Philippines.
Stablecoin Context
Stablecoin activity on Polygon has been climbing sharply. The total market capitalization of stablecoins on the chain hit an all-time high of $3.6 billion on Apr. 10, making it the eighth-largest stablecoin chain by that measure.
Passage of the GENIUS Act in July of last year gave the asset class a fresh boost in trading volume, and traditional finance has kept piling in. Western Union launched its USD-pegged USDPT stablecoin on Solana (sol) on Sunday.
