The Arbitrum ecosystem has taken a significant step forward in enhancing flexibility and usability for developers and users alike. With the recent support for custom gas tokens on Arbitrum Orbit chains, builders can now choose which ERC20 token—including their own—to use for transaction fees. A major development within this framework is the official support for bridged USDC as a custom gas token, marking a pivotal moment for decentralized finance (DeFi) operations on layer-2 scaling solutions.
This integration is designed to improve the overall user experience, reduce volatility concerns, and increase accessibility for new projects and their communities. By leveraging one of the most widely recognized stablecoins, Arbitrum Orbit chains can now offer a more stable and user-friendly environment.
Understanding Custom Gas Tokens on Orbit Chains
Custom gas tokens allow blockchain networks to move beyond relying solely on native cryptocurrencies like Ether (ETH) for transaction fees. This flexibility is especially valuable for application-specific chains built using Arbitrum Orbit technology, as it enables them to create more tailored economic models.
For builders, this means greater control over the user experience and economic parameters of their chain. For users, it translates to more convenience and fewer barriers to interaction.
The Role of USDC as a Stablecoin
USDC (USD Coin) is a fully-regulated, fiat-backed stablecoin pegged 1:1 to the US dollar. Its widespread adoption and immense liquidity make it a cornerstone of the DeFi and broader crypto ecosystem. The ability to use bridged USDC for gas fees introduces a layer of predictability and stability previously unavailable when dealing with more volatile assets.
Benefits for Users Adopting USDC for Gas Fees
The integration of bridged USDC as a payment method for transaction costs offers immediate and tangible advantages for end-users interacting with Orbit chains.
Streamlined Transaction Process
Users no longer need to hold multiple tokens just to perform transactions. They can now pay for gas fees directly with USDC, a stablecoin many already possess and use for other DeFi activities. This simplifies the entire process of engaging with decentralized applications (dApps) on these chains.
Protection from Market Volatility
The price of ETH and other native cryptocurrencies can fluctuate significantly. This volatility directly impacts the cost of transactions, often making it difficult for users to predict fees. Since USDC is pegged to the US dollar, users can enjoy stable and predictable transaction costs, shielding them from the uncertainty of the crypto market.
Lower Barrier to Entry
For newcomers, the process of acquiring a network’s native token just to pay for gas can be a significant hurdle. By allowing gas payments in a universally recognized stablecoin, Orbit chains become much more accessible to a broader audience who may already be holding USDC.

Advantages for Builders and Developers
The support for bridged USDC as a gas token is equally transformative for project teams and developers building on the Arbitrum Orbit stack.
Rapid Chain Deployment and Configuration
Orbit Rollup-as-a-Service (RaaS) providers have integrated support for bridged USDC as a standard configuration option. This allows developers to quickly spin up their chains with this feature enabled from the outset, significantly speeding up development and deployment timelines.
Key infrastructure providers supporting this setup include AltLayer, Caldera, Conduit, and Gelato Network, with upcoming support from Ankr and Alchemy.
Access to Grant Funding and Support
Builders leveraging this new capability can also tap into additional resources. Circle’s USDC Grant Program is actively considering applications from projects that are utilizing bridged USDC as a gas token on their Orbit chain. This provides a fantastic opportunity for teams to secure funding and support for further development.
How to Get Started with USDC Gas Fees
For developers interested in implementing this feature, the process is straightforward.
- Choose an RaaS Provider: Select an Orbit Rollup-as-a-Service partner like AltLayer or Caldera that supports custom gas token configuration.
- Configure Your Chain: During the setup process, specify bridged USDC as your chosen gas token.
- Inform Your Users: Ensure your community knows they can now pay for transactions using USDC, simplifying their interaction with your dApp.
- Apply for Grants: Consider applying to the relevant grant programs to support your project's growth.

Frequently Asked Questions
What is a custom gas token?
A custom gas token is any ERC20 token that a blockchain network designates as acceptable for paying transaction fees, instead of relying solely on its native cryptocurrency. This gives builders more flexibility in designing their chain's economy.
Why is using USDC for gas fees beneficial?
Using USDC for gas fees provides price stability because it is pegged to the US dollar. This protects users from the volatility typically associated with crypto-based transaction fees and makes cost forecasting much easier for both users and developers.
Do I need to bridge USDC myself to use it for gas?
No. This announcement specifically refers to "bridged USDC" that is already available within the Arbitrum ecosystem. The infrastructure supports it directly, so users can utilize the USDC they hold on Arbitrum to pay for gas on Orbit chains.
As a builder, how do I enable USDC as a gas token on my Orbit chain?
Enabling this feature is handled through Orbit RaaS providers. During your chain's configuration with a provider like Conduit or Gelato, you can select bridged USDC as your custom gas token option.
Is there any financial support available for projects that implement this?
Yes. Circle’s USDC Grant Program is a potential source of funding for projects that are building Orbit chains and leveraging bridged USDC as a gas token. Teams are encouraged to apply to this program.
What is the difference between native USDC and bridged USDC?
Native USDC is issued directly on a given blockchain. Bridged USDC is an asset that originated on another chain (like Ethereum) and was moved to a new chain (like Arbitrum) via a cross-chain bridge. The announcement confirms that this bridged version is supported for gas payments.
The Future of Flexible Transaction Fees
The support for bridged USDC as a custom gas token is more than just a feature update; it's a sign of the maturing blockchain infrastructure. By prioritizing user experience and developer flexibility, Arbitrum is paving the way for more innovative and accessible Web3 applications.
This initiative is part of a broader collaboration between Arbitrum and Circle, hinting at more integrations and enhancements to come. The future of Orbit chains looks bright, with a focus on stability, usability, and continued growth.
