Crypto, Fintechs Race to Own Stablecoin Settlement Rails

Stablecoin issuers and fintech companies are building their own payment-focused blockchains and settlement infrastructure, each angling to control the rails where stablecoin transactions clear. Circle, Plasma and Stripe-backed projects represent three distinct approaches to capturing fees, liquidity and customer relationships in a market where stablecoin settlement rails are fast becoming strategic ground.

The moves come as stablecoin payments volume has roughly doubled to around $400 billion, according to Stripe’s 2025 annual letter. That growth has turned settlement infrastructure from a background utility into a competitive asset worth owning outright.

“Companies are looking to capture more of that value themselves by building or controlling the settlement layer,” Ran Goldi told Cointelegraph, summarizing the logic driving these launches.

Why Stablecoin Settlement Rails Are Becoming Strategic Infrastructure

Settlement rails are the underlying networks where stablecoin transactions finalize. Whoever operates these rails can influence transaction fees, set liquidity terms and shape the economics of every payment that flows through.

Cointelegraph reported that stablecoin issuers and fintech-linked firms are launching payment-focused blockchains specifically to control more of this settlement infrastructure. The pattern is clear across multiple companies, though the competitive landscape is still forming and no single firm has established dominance.

The trend reflects a broader shift in how crypto-native and traditional financial firms view stablecoin infrastructure. Rather than building on existing general-purpose chains, these companies are designing purpose-built networks optimized for payment settlement, foreign exchange and on/off-ramp flows.

Circle, Plasma and Stripe Show Different Paths to Control

Circle launched the Arc public testnet in 2025, positioning it as dedicated infrastructure for stablecoin finance. The roadmap includes using stablecoins for gas fees, native stablecoin swaps and built-in FX liquidity. Wallets, infrastructure providers, exchanges and market participants have joined the testnet.

Arc’s design embeds stablecoins into the chain’s core mechanics rather than treating them as tokens layered on top. That approach gives Circle direct influence over swap pricing, FX conversion and the fee structure for every transaction settling on its network.

Plasma took a different route, announcing its mainnet beta for September 25, 2025, with zero-fee USDt transfers available through its dashboard. The project said $2 billion in stablecoins would be active on the network from day one, deployed across more than 100 DeFi partners.

Plasma’s stated mission centers on becoming the foundation for global money movement, targeting payments, FX, card networks and on/off-ramps as core use cases. The zero-fee model is a deliberate competitive lever, potentially pressuring rivals who rely on per-transaction revenue.

Stripe, already a dominant force in traditional payments, completed its $1.1 billion acquisition of Bridge, a stablecoin orchestration platform, in October 2024. The company’s 2025 annual letter then revealed Tempo, built with Paradigm, as a blockchain purpose-built for payments with mainnet described as launching soon.

The three approaches illustrate distinct strategies. Circle is extending its position as a stablecoin issuer into infrastructure. Plasma is competing on cost with zero-fee transfers. Stripe is leveraging its existing institutional payment relationships to bridge traditional finance and stablecoin settlement.

What This Means for Payments and Stablecoin Adoption

Each project targets the same economic opportunity from a different angle: capturing value at the settlement layer where payments, foreign exchange and liquidity provision converge. Plasma’s explicit focus on card networks and on/off-ramps suggests these new rails could eventually compete with or complement existing payment processors.

Circle’s inclusion of native FX liquidity in Arc’s roadmap points to cross-border payments as a primary battleground. Stablecoin-native FX conversion at the settlement layer could undercut the spreads charged by traditional correspondent banking networks.

These infrastructure moves coincide with what multiple sources describe as maturing stablecoin regulation worldwide. Plasma explicitly framed the U.S. regulatory environment as moving in a positive direction, while the broader post-2025 policy landscape has given firms more confidence to invest in dedicated settlement infrastructure.

Reliable adoption metrics and revenue comparisons across these competing rails remain limited. The research does not yet show hard transaction-fee data or customer adoption figures that would rank these projects against each other. The competitive framing is directionally supported by the volume of launches and acquisitions, but a definitive market-share picture has not emerged.

What is concrete: major firms across both crypto-native and traditional financial sectors are committing significant capital to owning stablecoin settlement infrastructure. Whether the market consolidates around one dominant rail or fragments across specialized networks will depend on execution, regulatory outcomes and which fee models attract the most transaction volume.
