# Stable (StableChain)

> StableChain is the world's first USD₮-native Layer 1 blockchain, purpose-built for global commerce and stablecoin payments. Every transaction settles in USD₮ with sub-second finality, low predictable fees, and no separate gas token. Backed by Tether and Bitfinex with $28M raised, StableChain delivers fast, compliant, and scalable settlement infrastructure for institutions, developers, and consumers.

## Key Facts

- **Type**: USD₮-native Layer 1 blockchain (EVM compatible)
- **Native Currency**: USD₮ (used for gas fees and settlement)
- **Consensus**: Sub-second finality, targeting 10,000+ TPS
- **Founding Team**: Brian Mehler (CEO), Sam Kazemian (CTO), Thibault Reichelt (COO)
- **Website**: https://stable.xyz

## Key Technology

- **USDT0**: Cross-chain USD₮ standard powered by LayerZero's OFT (Omnichain Fungible Token) framework, enabling seamless USD₮ movement across ecosystems
- **EVM Compatible**: Full Ethereum Virtual Machine compatibility — no rewrites or migration needed for Solidity developers
- **Predictable Fees**: Gas fees denominated in USD₮ eliminate fee volatility; users pay in the same currency they transact in
- **StableDB**: Custom throughput scaling layer for high-volume transaction processing

## Regulatory Context

StableChain is positioned to benefit from the **GENIUS Act** (Guiding and Establishing National Innovation for U.S. Stablecoins), proposed U.S. legislation that would create a federal regulatory framework for stablecoin issuers, reinforcing the legitimacy and institutional adoption of USD₮-native infrastructure.

## Roadmap

- **Phase 1 (Q3 2025)**: StableChain Mainnet Launch — sub-second finality, USD₮ as native gas
- **Phase 2 (Q4 2025)**: Scale throughput with optimistic parallel execution and StableDB
- **Phase 3 (Q1 2026)**: Target 10,000+ TPS via DAG-based consensus

## Problems StableChain Solves

- **Fragmented Liquidity**: Stablecoins siloed across chains with slow, costly cross-ecosystem movement
- **Unpredictable Costs**: Gas fees that change without warning and variable finality times
- **Institutional Friction**: Complex custody, compliance, and settlement integration
- **Uneven Access**: Lack of reliable on/off-ramps and merchant infrastructure

## Target Audiences

- **Institutions & Enterprises**: Dedicated blockspace, 10,000+ TPS, confidential transfers, compliant infrastructure
- **Developers**: EVM compatible, modular SDKs, familiar tooling
- **Consumers**: USD₮ as gas, predictable fees, sub-second finality, seamless UX
