Introducing Arc, an open Layer-1 blockchain purpose-built for stablecoin finance. From payments to FX to capital markets, Arc is the home for builders innovating with digital money and tokenized value on the internet. Stablecoins have shown us what’s possible. They’ve powered trillions in onchain transactions and unlocked a faster, more open financial system. Arc is designed to provide an enterprise-grade foundation with the performance, reliability, and liquidity needed to scale stablecoin use cases worldwide. Featuring: ✅ USDC as native gas ✅ Built-in FX engine ✅ Deterministic sub-second finality ✅ Opt-in privacy ✅ Full Circle platform integration At its core is Malachite, a high-performance consensus engine developed by Informal Systems that powers Arc with safety, liveness, and resilience at scale. Arc expands the design space for stablecoins by uniting speed with certainty and delivering the native tooling needed to meet real-world business obligations. Open and composable, Arc is designed to interoperate seamlessly with the broader multichain ecosystem. Fully EVM-compatible, developers will be able to build on Arc using the same frameworks and tooling they know and trust. Together, we’re laying the foundation to move stablecoin finance from early adoption to globally trusted infrastructure. Arc will enter private testnet in the coming weeks, with public testnet expected this fall. Read the litepaper → Join us in building the new internet financial system →
