What Did Solayer Launch?
Solayer has launched a Visa-compatible payment card that allows users to spend USDC balances through in-store, online and contactless transactions, expanding its Solayer Pay product into physical card payments.
The card can be ordered through the Solayer Pay app and supports ATM withdrawals in supported regions, according to the company’s announcement. Existing Solayer Pay users can request the card for free, while new users must pay a $20 annual activation fee.
The product is designed to let users spend USDC balances globally through Visa-linked payment infrastructure directly from their Solayer Pay accounts. That places Solayer inside a growing group of crypto and payments firms trying to connect stablecoin balances with traditional card rails rather than keeping digital assets confined to exchanges, wallets or onchain transfers.
Solayer Pay launched in April 2025 under the name Emerald Card and initially rolled out to 40,000 users across more than 100 countries, according to the company. The new physical card builds on that earlier payment product by adding another access point for users who want to store, transfer and spend digital assets through a card-linked account.
Why Does This Matter for Stablecoin Payments?
The launch shows how stablecoin payment products are moving closer to mainstream card infrastructure. USDC is already widely used for digital dollar transfers, crypto trading and settlement. A Visa-compatible card turns that balance into a spendable payment source for everyday transactions, subject to the regions and merchants where the product is supported.
The model also reflects a larger shift in crypto payments. Earlier stablecoin use was mainly tied to exchange funding, DeFi activity and cross-border transfers. Card-linked products now aim to make stablecoins usable at regular payment points without requiring merchants to directly handle blockchain transactions.
For users, the appeal is direct access to digital dollar balances through familiar payment formats. For platforms, the product creates a stronger link between wallet activity and everyday spending. For card networks and payment processors, stablecoins are becoming another settlement and funding layer connected to existing payment rails.
Investor Takeaway
Solayer’s card launch is not only a product update. It reflects a wider race to make stablecoins usable through existing payment networks, with USDC and other dollar-backed tokens increasingly moving from crypto-native balances into card-linked spending products.
How Does Solayer Fit Into the Infrastructure Layer?
Solayer develops infiniSVM, a layer-1 network compatible with the Solana Virtual Machine. The network is designed for high-throughput onchain applications and uses Solana for gas fees.
That infrastructure angle matters because Solayer is not only launching a consumer-facing payment card. It is also trying to connect payment activity with a broader blockchain environment built around fast onchain applications. The card gives the company a user-facing product while its layer-1 network provides the technical base for applications that may depend on higher transaction throughput.
The card also gives Solayer Pay a clearer commercial role. A wallet or payments app can hold users only if it supports practical account activity. Spending, transfers and ATM access give the platform more frequent use cases than passive token storage alone.
Still, execution will depend on availability, compliance, card acceptance, regional restrictions and user trust. Stablecoin cards rely on traditional payment partners, identity checks and jurisdiction-specific rules. That means global branding does not automatically translate into uniform access in every market.
Why Are More Firms Launching Stablecoin Cards?
Solayer’s launch follows a series of stablecoin-linked card products from crypto exchanges, wallet providers and payment companies. In January, OKX launched a Mastercard-linked payment card for European users through regulated issuer Monavate, allowing verified customers to spend stablecoins including USDC and Paxos’ Global Dollar.
In February, MetaMask expanded its Mastercard-linked crypto payment card across the United States, including New York for the first time. The card allows users to spend digital assets directly from self-custodial wallets, marking another attempt to connect crypto balances with card-based payments.
In March, Visa and Stripe-owned Bridge expanded their stablecoin-linked card program to 18 countries and said they planned to roll out the product across more than 100 countries by the end of 2026. The companies also began testing stablecoin settlement through Visa’s pilot program.
Mastercard has also moved deeper into stablecoin infrastructure. In March, it agreed to acquire BVNK, a stablecoin infrastructure company, in a deal valued at up to $1.8 billion. BVNK provides infrastructure for businesses to send and receive stablecoin payments across blockchain networks in more than 130 countries.
Investor Takeaway
The stablecoin card market is becoming a competition between crypto-native platforms, wallet providers, exchanges and global payment networks. The firms that win distribution may control a larger share of stablecoin payment activity as digital dollar balances become easier to spend.
What Does Stablecoin Growth Say About Demand?
The stablecoin market has continued to expand. DefiLlama data shows total stablecoin supply rising from about $243.3 billion in May 2025 to around $322.5 billion today, an increase of about $79 billion.
Tether remains the dominant issuer. Its USDt has a market capitalization of about $189.7 billion, representing roughly 58.8% of the total stablecoin market. Circle’s USDC ranks second with a market capitalization of about $76.7 billion.
