Why Arc for eCommerce

Arc is purpose-built for stablecoin finance, which simplifies building eCommerce applications.
Sub-second deterministic finality — the guarantee that a confirmed transaction cannot be reversed — means no chargebacks and immediate payment confirmation for both merchants and customers.
Customers and merchants transact in USDC, not volatile gas tokens. See gas and fees for details on Arc’s stable fee model.
Native hooks for KYC/AML screening from Elliptic and TRM Labs let you meet regulatory requirements without building custom infrastructure.
Accept payments from any chain supported by App Kit via bridging, so customers can pay from the chain they already use.
Smart contracts enable milestone-based payment release, refund protocols, and conditional settlement logic for marketplace and SaaS checkout flows. See the Arc escrow sample app for a working example.
Build with Solidity, ethers.js, or viem. Your existing web3 development workflows work unchanged on Arc — see EVM compatibility for details. Deploy on Arc to get started.
