# eCommerce Checkout

> Accept stablecoin payments in your online store with fast settlement, low fees, and built-in compliance on Arc.

Add stablecoin checkout to your eCommerce application. Arc gives you
[instant settlement](/arc/concepts/deterministic-finality), programmable escrow,
and native [compliance hooks](/arc/tools/compliance-vendors) so you can accept
USDC and EURC payments with confidence.

For peer-to-peer transfers, see [P2P Payments](/build/payments). For
multi-currency conversion at checkout, see
[Stablecoin FX](/build/stablecoin-fx). For agent-initiated purchases, see
[Agentic Economy](/build/agentic-economy).

## Sample apps

## Why Arc for eCommerce

Arc is purpose-built for stablecoin finance, which simplifies building eCommerce
applications.

<AccordionGroup>
  <Accordion title="Instant settlement">
    [Sub-second deterministic finality](/arc/concepts/deterministic-finality) —
    the guarantee that a confirmed transaction cannot be reversed — means no
    chargebacks and immediate payment confirmation for both merchants and
    customers.
  </Accordion>

  <Accordion title="Stablecoin-native gas">
    Customers and merchants transact in USDC, not volatile gas tokens. See [gas
    and fees](/arc/references/gas-and-fees) for details on Arc's stable fee
    model.
  </Accordion>

  <Accordion title="Compliance-ready">
    Native hooks for KYC/AML screening from [Elliptic and TRM
    Labs](/arc/tools/compliance-vendors) let you meet regulatory requirements
    without building custom infrastructure.
  </Accordion>

  <Accordion title="Multichain reach">
    Accept payments from any chain [supported by App
    Kit](/app-kit/references/supported-blockchains) via
    [bridging](/app-kit/bridge), so customers can pay from the chain they
    already use.
  </Accordion>

  <Accordion title="Programmable escrow">
    Smart contracts enable milestone-based payment release, refund protocols,
    and conditional settlement logic for marketplace and SaaS checkout flows.
    See the [Arc escrow](https://github.com/circlefin/arc-escrow) sample app for
    a working example.
  </Accordion>

  <Accordion title="Standard EVM tooling">
    Build with Solidity, ethers.js, or viem. Your existing web3 development
    workflows work unchanged on Arc — see [EVM
    compatibility](/arc/references/evm-differences) for details. [Deploy on
    Arc](/arc/tutorials/deploy-on-arc) to get started.
