Key Features — Why It’s a Game-Changer
1. Stablecoin as the Native Gas Token
Arc uses stablecoins (like USDC) directly to pay for transaction fees. This eliminates the volatility risk of traditional crypto gas fees, ensuring predictable, dollar-based costs for businesses and developers.
2. Integrated Foreign Exchange (FX) Engine
Arc has a built-in FX mechanism for real-time quoting and atomic settlement between different stablecoins. This allows instant, onchain currency conversion without relying on external exchanges.
3. Sub-Second Finality
Its consensus protocol delivers near-instant, deterministic settlement. Transactions are finalized in under a second, providing a payments experience that rivals or surpasses traditional financial rails.
4. Opt-In Privacy for Enterprises
Businesses can choose to enable privacy for specific balances and transactions. This makes it possible to maintain confidentiality for sensitive financial activity while keeping overall system transparency intact.
5. Seamless Integration with Existing Infrastructure
Arc is fully aligned with a broader ecosystem of payment, settlement, and compliance tools—supporting wallets, smart contracts, and crosschain capabilities without additional integration complexity.
6. EVM Compatibility & Multichain Connectivity
Developers can use familiar Ethereum tools and frameworks while tapping into a multichain-friendly architecture that connects rather than competes with other blockchains.
