Stablecoins are gaining significant market dominance, gradually integrating into traditional finance and retail markets. For instance, some supermarkets in South American countries have begun pricing goods directly in US dollar stablecoins like USDT. These real-world applications demonstrate a clear expansion trend, which may require new types of infrastructure to support further growth.
Recently, discussions have emerged about stablecoin-specific chains such as Plasma and Stable. What exactly are these projects, how do they differ, and are they truly essential for the future of digital payments?
The Rise of Stablecoin-Specific Blockchains
Plasma and Stable are designed to enable faster, cheaper, and more scalable stablecoin transfers. Their core concept revolves around attracting liquidity from older networks that, while inefficient, still hold substantial stablecoin volumes.
Although these networks have some fundamental differences, their similarities are perhaps more significant. Most notably, both share USDT as their central hub. More specifically, both integrate USDT0—a non-fragmented version of USDT that can be natively exchanged across different blockchain networks through LayerZero. Currently primarily based on Arbitrum while expanding to emerging chains, USDT0 offers end-users an experience identical to regular USDT.
Understanding Plasma's Approach
Plasma is constructed as a Bitcoin sidechain, meaning it inherits Bitcoin's security through a peg mechanism while maintaining its own independent consensus. In simple terms, malicious actors would need to compromise Bitcoin itself to alter Plasma's history, though Bitcoin doesn't actually validate Plasma's blocks.
The system is designed for thousands of transactions per second with approximately one-second finality, making it ideal for rapid USDT transfers. Its most distinctive feature is that basic USDT transfers require no gas fees whatsoever. So how does it generate revenue? The answer lies in its business model: while USDT transfers are free, all other on-chain operations incur gas fees. By attracting users with free transfers to achieve scale, increased user activity drives volume for fee-generating operations—a strategy leveraging secondary effects for profitability.
Another unique aspect is that users can choose to pay transaction fees using either USDT or Bitcoin. The platform is fully EVM-compatible, allowing developers to easily deploy Ethereum applications. With backing from both Bitfinex exchange and Tether, the focus on supporting USDT and Bitcoin becomes easily understandable.
Examining Stable's Architecture
Stable employs a different implementation approach. It operates as an independent Layer 1 network rather than a sidechain, utilizing its own proof-of-stake consensus mechanism. Similar to Plasma, Stable is EVM-compatible and offers zero gas fees for USDT transfers while requiring fees for all other on-chain operations. A key differentiating feature is that Stable exclusively accepts USDT for gas fee payments.
Supported by Bitfinex and USDT0, Stable has involved Tether's CEO Paolo Ardoino as an advisor from its inception, clearly indicating its focus on the dominant stablecoin in circulation.
Additionally, Stable appears to place greater emphasis on corporate and institutional clients, with specific features tailored to this market segment.
Privacy Protection Strategies
Both networks prioritize privacy protection. While specific implementation details remain unclear, Plasma's mentioned "Shielded transactions" concept and Stable's confidential transfer technology both aim to preserve transaction privacy while maintaining regulatory compliance.
Currently, concrete information about both infrastructures remains limited. Beyond the technical differences already outlined, Stable platform is expected to incorporate additional institution-friendly features including:
- Dedicated block space for enterprises: Ensuring stable transaction speeds and predictable fees regardless of network congestion
- USDT transfer aggregators: Bundling multiple USDT0 transfers to improve processing speed and reduce transaction costs
Current Real-World Applications
Of USDT's $158.3 billion market capitalization, 49.27% circulates through the Tron network. While newer blockchain ecosystems have developed more comprehensive features, Tron initially represented the cheapest and most efficient option for USDT transactions. Consequently, Tether has continued to use this chain for minting and transferring funds, though Tron wasn't originally designed for this purpose.
More significantly, Tether participates primarily as a user rather than an active ecosystem participant on Tron. The potential loss of dominance over USDT could significantly impact Tron's viability, especially considering its limited sustainable ecosystem development.
The core strategy behind chains like Plasma and Stable involves targeting ecosystems with weak DeFi foundations to absorb liquidity. Rather than eliminating competitors, these networks aim to build hubs centered around USDT payments and commercial settlements—particularly leveraging free transfers to surpass less efficient chain ecosystems. The attracted liquidity naturally brings users and capital, potentially fostering new DeFi protocols and ultimately building vibrant ecosystems.
This development could potentially create a new SWIFT-like system specifically for stablecoins, where Tether would not only issue stablecoins but also serve as dual foundation supporting both currency value and underlying infrastructure. With USDT's scale advantage, Tether stands to benefit while Plasma and Stable would enjoy the advantages of high-speed capital movement on their networks.
Other blockchain ecosystems certainly won't be forgotten in this evolution. Solana with its focus on debit card payments and fiat exchange channels, Ethereum and its Layer 2 solutions concentrating on DeFi, and emerging chains with specific application scenarios will likely continue to thrive.
Recent Developments and Progress
While not necessarily indicative of long-term sustainability, short-term interest has been demonstrated through Plasma's public token sale, which reached its deposit limit of $1 billion. This suggests that at launch, the chain would rank 12th in stablecoin circulation volume.
Plasma has also announced several partnerships including:
- Yellow Card: Focused on USDT transfer services in African regions
- BiLira Kripto: Connecting Turkish lira with stablecoins for cross-border payments
- Uranium Digital: Bringing commodity trading on-chain
- Axis: Launching yield-bearing synthetic dollars (xyUSD)
- Collaborations with Curve and Ethena
The market continues to watch for Stable's subsequent developments with equal interest.

Frequently Asked Questions
What are stablecoin-specific blockchains?
Stablecoin-specific blockchains are specialized networks designed primarily for stablecoin transactions. They optimize for speed, cost efficiency, and scalability in stablecoin transfers, often offering features like zero gas fees for specific stablecoin transactions while maintaining compatibility with existing blockchain ecosystems.
How do Plasma and Stable differ from regular blockchains?
Unlike general-purpose blockchains, Plasma and Stable are specifically optimized for stablecoin operations. They typically offer faster settlement times, lower or zero transaction fees for stablecoin transfers, and enhanced privacy features while maintaining compatibility with existing smart contract platforms through EVM support.
Why would users choose stablecoin-specific chains over established networks?
Users might prefer these specialized chains for significantly reduced transaction costs, faster settlement times, enhanced privacy features, and potentially better institutional services. The zero-fee structure for stablecoin transfers presents a compelling advantage for frequent users of stablecoins.
Are these networks secure compared to established blockchains?
Security models vary between implementations. Plasma leverages Bitcoin's security through its sidechain architecture, while Stable uses its own proof-of-stake consensus. Both approaches have different security considerations, and users should evaluate each network's security model based on their specific needs.
How do these networks generate revenue without charging for stablecoin transfers?
These networks typically employ a freemium model where basic stablecoin transfers are free, but other operations—including smart contract executions, token swaps, and advanced features—incur fees. This approach attracts users with free basic services while monetizing value-added operations.
What institutional features do these networks offer?
Institutional features may include dedicated block space ensuring consistent transaction speeds regardless of network congestion, enterprise-grade privacy protections, transfer aggregation services, and specialized compliance tools tailored to organizational requirements.
Conclusion
The success of stablecoin-specific blockchain projects isn't guaranteed. The "stablecoin chain" concept might represent sophisticated marketing strategy—creating spotlight effect for USDT while generating buzz with zero gas fee promises. Essentially, this approach sets the stage for vampire attacks, though not through token incentives as seen with SushiSwap, but rather through eliminating user transaction costs. In many ways, this represents a freemium model for transactions.
Both chains appear ready for deployment. The more interesting development will be observing how they differentiate themselves, select optimal market channels, and—most importantly—whether they can build sustainable business ecosystems that extend beyond mere transactional efficiency. The evolution of these specialized networks will significantly influence how stablecoins integrate into global financial systems in the coming years.
