Ethereum scaling platform Polygon has introduced private stablecoin payments as part of a broader push to attract businesses and institutional users to its network.
In a statement released Sunday, Polygon unveiled a new wallet feature that allows users to route transactions privately through a shielded pool, with verification powered by zero-knowledge proofs. The feature comes through an integration with privacy protocol Hinkal.
“For onchain payments to reach mainstream adoption, businesses require privacy—not to evade regulators, but to protect operational details,” said Polygon community lead Smokey in a post on X.
Privacy emerged as a major theme in crypto throughout 2025, with tokens tied to privacy-focused projects outperforming even as the broader market declined. Polygon emphasized that confidentiality remains a key barrier preventing institutions from moving large volumes onchain.
“Confidentiality has been the biggest missing piece between onchain infrastructure and what institutional finance needs to handle significant stablecoin flows,” the company said.
“Banks, treasuries and payments teams already live with confidentiality on traditional rails. They won’t move operational flows onto a ledger that broadcasts every counterparty and every amount to every observer on the network.”
Polygon said its new feature allows users to keep transactions hidden from public view while still maintaining compliance and auditability, emphasizing that “privacy means opacity to the market, not opacity to regulators.”
This is achieved in two main ways. First, every private transaction on Polygon undergoes Know Your Transaction (KYT) screening before execution. Second, according to Hinkal’s documentation, users can generate audit files that can be shared with tax authorities or regulators when required.
Polygon’s move follows a similar push by layer-1 blockchain Aptos, which launched its Confidential APT coin on April 24. The token is pegged to the value of APT and uses zero-knowledge proofs to both conceal and verify transaction details.
Meanwhile, Polygon’s stablecoin ecosystem has been expanding. The total market capitalization of stablecoins on the network reached an all-time high of $3.6 billion on April 10, according to DefiLlama, making it the eighth-largest chain for stablecoins.
Interest in the sector has also been boosted by regulatory developments, including the passage of the stablecoin-friendly GENIUS Act in July last year. More recently, Western Union entered the space by launching its USD-pegged USDPT stablecoin on Solana.
