Polygon introduces private stablecoin payments to court institutions

Polygon has introduced a private stablecoin payment feature designed to meet institutional requirements for confidential on-chain transactions.

According to a statement released by Polygon, the new wallet capability allows users to route transfers through a shielded pool, with transaction validity confirmed using zero-knowledge proofs as part of an integration with privacy protocol Hinkal. 

The system allows funds to move without exposing counterparties or transaction amounts on public ledgers, while still preserving verifiability.

Privacy layer targets institutional flows

Polygon community lead Smokey said on X that “for onchain payments to go mainstream, businesses need privacy,” adding that the requirement centers on operational confidentiality rather than avoiding regulatory oversight. 

Polygon added that “confidentiality has been the single biggest gap between on-chain rails and what institutional finance actually needs to move serious stablecoin volume,” arguing that financial firms already operate with protected transaction data in traditional systems.

In its explanation, Polygon said institutions such as banks and treasury teams are unlikely to move operational flows to public ledgers that expose counterparties and transaction sizes, describing its approach as “privacy means opacity to the market, not opacity to regulators.” 

The company positioned the feature as a step toward enabling large-scale stablecoin usage without compromising compliance expectations.

Compliance built into private transfers

Polygon detailed that each private transfer undergoes Know Your Transaction screening before execution, while documentation from Hinkal shows users can generate audit files for regulators or tax authorities. 

According to the firm, this structure allows transaction data to remain hidden from public observers while still giving institutions the ability to meet reporting obligations when required.

The rollout follows a series of moves by Polygon to build a payments-focused stack.

In April, Polygon Labs disclosed plans to raise up to US$100 million (approx. $139.4 million) to expand its payments business, alongside a previously announced US$250 million (approx. $348.5 million) acquisition program targeting firms such as Coinme and Sequence. 

CEO Marc Boiron told Reuters at the time that the company intends to establish itself as a regulated payments entity in the US, identifying payments as the most compelling use case for blockchain infrastructure.

Polygon has also been developing its Open Money Stack, which the company describes as a modular platform aimed at enabling cross-chain and cross-currency transfers to function like a single network for enterprises. 

Internal figures shared by Polygon indicate that the network has already facilitated roughly US$2.3 trillion (approx. $3.2 trillion) in on-chain value transfers, while combined activity across Polygon, Coinme, and Sequence has exceeded US$1 billion (approx. $1.4 billion) in off-chain sales and more than US$2 trillion (approx. $2.8 trillion) in on-chain flows.

Data from DefiLlama shows stablecoin market capitalization on Polygon reached US$3.6 billion (approx. $5 billion) on April 10, placing it as the eighth largest chain for stablecoin activity. 

Separate analytics cited by Polygon in earlier updates showed the network handling a significant share of non-USD stablecoin transfers, reinforcing its position as a payments rail for local currency use cases.

Competition around private and institutional grade transactions has also intensified.

On April 24, layer 1 blockchain Aptos launched Confidential APT, a token pegged to Aptos (APT) that uses zero-knowledge proofs to conceal transfer details while maintaining verification.

Rising institutional interest in stablecoins has followed regulatory developments such as the GENIUS Act, which supported activity in the sector. 

On Sunday, Western Union launched a USD-pegged stablecoin, USDPT, on Solana, extending participation from traditional finance firms into blockchain-based payment systems.
