what's Arc?
Arc is an open Layer-1 blockchain developed by Circle, designed specifically for stablecoin finance and tokenized assets. It uses USDC as its native gas token, enabling predictable dollar-based fees and sub-second transaction finality through its Malachite consensus mechanism, a permissioned proof-of-authority system run by regulated institutions. The network supports features like encrypted mempools to mitigate malicious MEV, on-chain foreign exchange for stablecoins, and integration with Circle's broader ecosystem for payments, capital markets, and cross-border transactions. Built to bridge traditional finance and blockchain, Arc emphasizes compliance, privacy controls, and high throughput (up to 3,000 TPS) while remaining EVM-compatible for developer accessibility. It facilitates tokenized real-world assets, yield-bearing instruments, and seamless interoperability with other chains via bridges like Chainlink and LayerZero. Early testnet participants include major institutions such as BlackRock, Visa, and HSBC, positioning Arc as infrastructure for institutional-grade on-chain finance.
Arc launched a Builders Fund, partnered with LianLian, and acquired Interop Labs for multichain growth.
