Stablecoin Issuers Build Payment Blockchains to Control Settlement

Stablecoin Issuers and Fintech Firms Launch Payment-Focused Blockchains – Control of Settlement Infrastructure Becomes Strategic Priority

Key Takeaways

• Stablecoin issuers and fintech-linked firms are launching payment-focused layer-1 blockchains to control stablecoin settlement infrastructure.
• Tether-backed Plasma launched its mainnet in September 2025 after raising $24 million earlier that year.
• Circle introduced the public testnet for Arc, a layer-1 blockchain designed for stablecoin finance.
• Fintech companies, including Stripe, are expanding into stablecoin infrastructure through acquisitions and incubation of new networks.
• Industry executives describe ownership of payment rails as strategically important for capturing transaction-related revenue.

Shift From General-Purpose Blockchains to Payment-Focused Networks

Stablecoin issuers and fintech-linked companies are building a new generation of blockchain networks designed specifically for institutional payment flows. According to research cited by Delphi Digital, this marks a structural shift away from general-purpose layer-1 networks that support broad token issuance and smart contract activity.

Instead of relying on established public blockchains for settlement, several firms are developing their own infrastructure optimized for stablecoin transfers, particularly US dollar-denominated tokens. The focus is on improving efficiency for cross-border payments and large-scale settlement activity rather than supporting diverse decentralized applications.

This development reflects growing competition to control the infrastructure layer that underpins stablecoin transactions. Stablecoins are widely regarded within the industry as one of crypto’s most established real-world use cases, particularly for cross-border payments and digital dollar transfers.

Tether-Backed Plasma and Circle’s Arc Target Stablecoin Finance

Among the projects highlighted is Plasma, a public layer-1 network backed by Tether. Plasma is optimized for cross-border transactions involving USDt (USDT). The project raised $24 million in February 2025 and launched its mainnet on Sept. 25, 2025.

Circle, another major stablecoin issuer, introduced the public testnet for Arc in October 2025. Arc is described as an open layer-1 blockchain purpose-built for stablecoin finance. The initiative signals Circle’s intent to operate not only as a token issuer but also as a provider of underlying settlement infrastructure.

By building proprietary networks, stablecoin issuers aim to reduce reliance on external ecosystems and gain greater control over transaction processing and associated fees.

Fintech Companies Expand Into Stablecoin Settlement Infrastructure

The push to control payment rails is not limited to crypto-native firms. Fintech companies are also moving into stablecoin settlement infrastructure.

Tempo announced that its mainnet is live, describing the network as a merchant-focused settlement layer built for high-throughput stablecoin transactions. The project states that it is incubated by Paradigm and Stripe.

Stripe has made several acquisitions related to stablecoin and crypto infrastructure. In October 2024, it acquired stablecoin infrastructure startup Birdge for $1.1 billion. In June 2025, Stripe acquired crypto wallet infrastructure provider Privy. On Jan. 14, it also purchased billing platform Metronome.

According to Delphi Digital, these acquisitions position Stripe to control more of the issuance, wallet, billing, and settlement layers surrounding stablecoin payments. This approach integrates multiple components of the payment workflow under a single corporate structure.

Why Control of Payment Rails Is Considered Strategically Important

Industry executives describe ownership of payment rails as increasingly important from a revenue perspective. Ran Goldi, senior vice president of payments and network at Fireblocks, said that instead of relying on external networks and paying fees to ecosystems such as Ethereum, companies are seeking to capture more value by building or controlling their own settlement layers.

For payment companies, owning the underlying infrastructure allows them to avoid paying external network fees for mint and burn operations of stablecoins. This shifts economic benefits from public blockchain ecosystems to private or specialized networks.

Alvin Kan, chief operating officer at Bitget Wallet, described stablecoin payment infrastructure as a new revenue layer. As protocol-level settlement costs decline, he noted that value capture moves toward orchestration layers surrounding the rail. These include compliance services, foreign exchange conversion, wallet infrastructure, onramps and offramps, local payout connectivity, and merchant integration.

Irina Chuchkina, chief growth officer of Wallet in Telegram, stated that stablecoin payment rails could become a defining revenue driver for the current market cycle. She compared the role of settlement infrastructure to that of traditional card networks, which derived influence from owning payment processing systems rather than issuing currency.

Chuchkina also pointed to interoperability with agentic artificial intelligence as a potential differentiator for companies building settlement rails, suggesting that integration with automated systems may influence how value flows through these networks.

Implications for Crypto Payment Users and Platforms

For users of crypto payment services, including those interacting with online platforms that accept stablecoins, the development of specialized settlement networks may affect how transactions are processed behind the scenes. While the source material does not specify changes to user fees or transaction speeds, the emphasis on high throughput and cost control indicates that infrastructure providers are targeting efficiency and scalability.

For platforms that rely on stablecoin transactions, such as online merchants or service providers, control of settlement layers may influence fee structures, compliance processes, and integration options. As companies consolidate issuance, wallet services, billing, and settlement within integrated ecosystems, operational workflows could become more centralized within specific infrastructure providers.

The competition to build and operate these networks underscores that stablecoin payments are no longer limited to token issuance alone. Instead, infrastructure ownership is emerging as a focal point in the broader crypto and fintech landscape.

Our Assessment

Based on the reported developments, stablecoin issuers and fintech firms are expanding beyond token issuance into direct control of settlement infrastructure. Projects such as Tether-backed Plasma, Circle’s Arc, and Tempo’s merchant-focused network illustrate a shift toward specialized payment blockchains. At the same time, acquisitions by companies like Stripe indicate efforts to integrate issuance, wallets, billing, and settlement under unified control. The available information shows that ownership of payment rails is becoming a central competitive factor in the stablecoin sector.
