Polygon Labs has shipped shielded stablecoin payments directly inside its wallet, with <a class="ticker-mention" href="/en-US/token/usdc">USDC</a> and <a class="ticker-mention" href="/en-US/token/usdt">USDT</a> supported at launch. A new "Privately Send" option routes transfers through Hinkal's shielded pool rather than a standard on-chain path — hiding the sender, receiver, and amount from public observers via zero-knowledge proofs.
The implementation is non-custodial, meaning users retain control of funds throughout. Polygon Labs added that every private transaction passes KYT screening before execution, threading the needle between financial privacy and compliance requirements.
For stablecoin payments at scale, shielded transfers remove one of the biggest friction points for business use: the exposure of counterparty and transaction size to anyone watching the chain.
