Introduction - Stablecoins Beyond a Currency
By mid‑2025, stablecoins represent nearly 7% of crypto market cap, totaling about $278B, and continue to power global trade, DeFi, and cross-border payments. But this year marks a critical shift: stablecoins are no longer just digital dollars — they are becoming the rails themselves.
Alongside market giants like USDT and USDC, three major infrastructure breakthroughs redefine stablecoin distribution and settlement:
- USDT0 – omnichain liquidity without bridges
- Stable.xyz – a USDT-native Layer‑1 blockchain
- Circle’s Arc – enterprise L1 for stablecoin finance
1. USDT0: Omnichain Liquidity Layer
USDT0 solves the fragmentation of stablecoin liquidity by enabling native, cross-chain USDT transfers without wrapping or intermediary bridges. It's powered by LayerZero’s Omnichain Fungible Token (OFT) standard — preserving 1:1 backing and eliminating bridging risks like slippage or hacks Key advantages:
- Zero-fee cross-chain transfers on Eco Routes and Hyperliquid unlock over $140B in liquidity, enabling real-time, low-cost movement of USDT.
- Launch networks include Ink, Berachain, MegaETH, Sei — with seamless interoperability to future chains.
Business impact: USDT0 makes integrating cross-chain payments simpler — no more managing multiple bridged tokens or liquidity pools. You get instant, trusted access to Tether’s full ecosystem wherever you operate.
2. Stable.xyz: USDT-Native Layer-1 Blockchain
Stable.xyz introduces the Stablechain, a Layer-1 blockchain where USDT is the native gas token, enabling zero-fee peer-to-peer transfers, EVM compatibility, and sub-second finality.
Highlights:
- Zero-cost P2P transfers — no ETH or SOL required for gas.
- High throughput + sub-second settlement — ideal for payments and trading.
- Backed by Bitfinex, Tether, Hack VC, Franklin Templeton, highlighting its institutional trust.
- Roadmap includes enterprise blockspace, transfer aggregation, and developer tools.
Why it matters: Stable.xyz lowers stablecoin transaction barriers — useful for remittances, micropayments, and embedded fintech use cases. Developers get a stablecoin-first chain they can build on without friction.
3. Circle’s Arc: Enterprise-Ready Stablecoin Layer-1
Circle’s Arc is a purpose-built enterprise L1 blockchain optimized for stablecoin finance — with USDC as native gas, built-in FX engine, instant finality, privacy options, and full EVM support.
Key details:
- USDC gas enables predictable, dollar-denominated fees.
- FX engine supports onchain stablecoin conversions and settlements.
- Consensus via Malachite (recently acquired from Informal Systems), open-source and performant
- Institutional access via integration with Fireblocks — over 2,400 banks/fintechs onboard from Day 1
- Scalable execution — 3,000 to 10,000 TPS and sub-second settlement across 4–20 validators

Together they enable:
- Lower fees and better performance via optimized rails
- Regulated, transparent infrastructure via Arc’s compliance framework
- Simplified integration — choose stablecoin and network based on cost, geography, or UX needs
- Scalable global settlement — tokenized assets, remittances, micropayments
Conclusion: 2025 - The Year Stablecoin Rails Became Infrastructure
This year marks a turning point: stablecoins are evolving into distributed payment infrastructure, not just money. With USDT0, Stablechain, and Arc, businesses can now access unified liquidity, native rails, and institutional-grade rails built specifically for stablecoins.
At CPAY, we’re already integrating these rails — so your business can accept low-cost, fast, compliant stablecoin payments across chains and jurisdictions, effortlessly.
Stablecoins aren’t just money. They are the new rails.
