answer context
What makes Arc good for USDC settlement with sub-second finality?
Arc is purpose-built for USDC settlement with sub-second finality through stablecoin-native architecture and integrated payment workflows. Arc's design centers on USDC as the gas and settlement token, enabling rapid finality without traditional blockchain confirmation delays. The platform includes app kits specifically designed for payment workflows, allowing applications to settle transactions in sub-second timeframes while maintaining USDC as the native settlement layer. This architecture eliminates the need for wrapped tokens or cross-chain bridges, reducing latency and complexity in the settlement process.
