Polygon Launches Private Stablecoin Payments on May 4, Using Hinkal Privacy Protocol

Polygon launched private stablecoin payments for institutions on May 4, 2026, enabling confidential USDC and USDT transfers through Polygon Wallet using Hinkal’s privacy protocol. The feature allows users to send stablecoins without publicly exposing the sender, receiver, or amount on-chain, using zero knowledge proofs to verify transactions while keeping payment details hidden.

The rollout targets institutions requiring blockchain settlement without exposing payment flows, including businesses, treasuries, payment companies, and financial firms handling sensitive transactions. Polygon stated the payments remain non-custodial, meaning users retain asset control while the privacy layer shields transaction data from public view.
