Overview
- Polygon’s wallet now offers a “Privately Send” option for USDC and USDT that routes transfers through Hinkal’s shielded pool using zero-knowledge proofs.
- The privacy layer hides the sender, recipient, and amount from public view, giving businesses confidentiality on a public blockchain.
- Every private payment is screened with Know Your Transaction checks before it executes, and users can generate audit files for tax or regulatory reviews.
- Transfers remain non-custodial so users keep control of funds during the process, a design pitched to treasury teams, payroll leads, and fintech firms.
- The launch fits a broader shift to privacy-ready stablecoin rails, with Aptos rolling out Confidential APT and Western Union issuing a USD-pegged token on Solana.
