DeCard and Polygon Labs Join Forces to Bring Stablecoin Spending to 150M Plus Merchants Worldwide

• DeCard is collaborating with Polygon Labs to integrate the Polygon network, enabling seamless deposits of USDT and USDC into DeCard and DeCard Luminaries.

• Holders of stablecoins on Polygon can now spend instantly at over 150 million merchants worldwide.

29 October 2025 — DeCard by DCS (formerly Diners Club Singapore), a next-generation card brand built for seamless stablecoin spending in the real world, has announced a strategic partnership with Polygon Labs, a Web3 software company developing Polygon Proof-of-Stake network. Through this collaboration, DeCard has integrated support for the Polygon network, enabling customers of both DeCard and DeCard Luminaries to deposit USDT and USDC on Polygon directly into their accounts.

Stablecoins now represent around $300 billion in circulating supply, but their utility has remained limited for many holders, facilitating only about $30 billion of transactions daily, less than 1 percent of global money flows. Despite their popularity, most people still find it challenging to use stablecoins for everyday transactions beyond holding or trading. DeCard was built to solve this gap—making stablecoin spending as easy as using any other payment card.

This collaboration also builds on DeCard’s broader strategy of integrating with more leading blockchain networks, ensuring that users have the choice, speed, and affordability they need when managing their stablecoins. With its flagship product, DeCard, and new premium offering, DeCard Luminaries, the brand continues to expand the real-world applications of stablecoins, making them practical, secure, and accessible for everyday life.

Polygon is a leading stablecoin payments platform, now supporting nearly $3 billion in stablecoin market cap. Polygon leads the market for micro and small USDC payments and was the first stablecoin payment network integrated with Stripe, offering sub-$0.001 transaction fees and settlement times under five seconds. With this integration, DeCard users who hold stablecoins on the Polygon network can now seamlessly deposit them into their DeCard accounts, enabling faster, cheaper, and more efficient real-world spending at over 150 million merchants worldwide.

Our mission at DeCard is to make stablecoin spending as intuitive as any other form of payment. We have been steadily expanding support across leading networks to give our users more choice and flexibility, and Polygon adds another layer of convenience and reach. By focusing on simplicity and reliability, we’re ensuring a future where stablecoin payments are as effortless and universal as any other form of spending,” said Joan Han, COO, DeCard.

"Stablecoins are one of the most important innovations in bridging traditional finance with the digital economy, but their real-world utility has been limited. Our collaboration with DeCard changes that. By enabling seamless USDT and USDC deposits and spending across 150 million merchants, we’re making stablecoins truly usable in everyday life, whether that’s buying coffee, booking travel, or shopping online. This is a major step toward realizing Polygon’s vision of making blockchain technology invisible to the user while unlocking real-world financial freedom for everyone," said Marc Boiron, CEO of Polygon Labs.
