FAQPage Schema
How do I deploy smart contracts on Circle's Arc blockchain?▼

To deploy smart contracts on Arc, you need to use development frameworks like Foundry or Hardhat. This structured guide provides the necessary references and tutorials to configure your environment and execute deployments on the Arc Testnet or Mainnet.

Can I use USDC as native gas for payments on Arc?▼

Yes, Arc supports USDC and EURC native gas denomination for payments and transfers. This allows developers to facilitate transactions with deterministic finality directly using stablecoins without needing secondary tokens for fees.

What is the best way to transfer USDC cross-chain using Arc?▼

The best way to transfer USDC cross-chain is by using Circle's CCTP protocol. This Skill guides you through implementing CCTP bridges to execute 1:1 USDC transfers between Arc and other supported blockchain networks.

How does StableFX integration work for real-time settlement on Arc?▼

StableFX integration on Arc enables real-time foreign exchange and programmable settlement within your dApps. This Skill provides the development references needed to leverage StableFX for compliant, high-performance financial workflows.

How do I sponsor gas fees for users using a Paymaster on Arc?▼

You can sponsor gas fees by integrating Paymaster and Account Abstraction features on Arc. This Skill covers how to implement these components to provide flexible payment options and gas sponsorship for your dApp users.

Does Arc support regulatory-compliant privacy features for dApps?▼

Yes, Arc includes opt-in privacy features designed specifically for regulatory-compliant dApp workflows. This guide helps developers implement these privacy controls to ensure dApps meet necessary compliance standards.
