Circle has introduced a significant update for the Polygon Proof-of-Stake (PoS) network by launching a native version of its USDC stablecoin. This development shifts how users and developers interact with USDC on this Layer-2 scaling solution, moving away from reliance on bridged assets. Here’s a comprehensive look at what this update entails, its implications for users, and how to navigate the transition smoothly.
What Is the New Native USDC on Polygon PoS?
On October 10, 2023, Circle launched a native version of USDC on the Polygon network. Before this release, the only form of USDC available on Polygon was a bridged version, commonly referred to as USDC.e. This bridged asset was supported but not directly issued by Circle.
The introduction of native USDC means the stablecoin is now directly available through Circle Mint and Circle APIs. It can be redeemed on a 1:1 basis for U.S. dollars. This upgrade offers businesses and developers a more streamlined way to use USDC in decentralized finance (DeFi) applications on Polygon without the need for bridging from Ethereum.
Since its launch, adoption has been growing. On-chain data shows that the native USDC contract has already been used by thousands of addresses and has facilitated tens of thousands of transfers. The total supply of native USDC on Polygon is steadily increasing, reflecting growing liquidity and user confidence.
Differences Between Bridged USDC and Native USDC
Prior to the update, users accessed USDC on Polygon through a bridged version (USDC.e). This involved transferring USDC from Ethereum to Polygon via a bridge, a process that incurred additional transaction fees and delays.
While Circle endorsed the bridged version, it did not issue it. This meant USDC.e could not be directly redeemed with Circle. The new native USDC eliminates these intermediate steps, allowing for near-instant, low-cost transfers directly supported by the issuer.
It’s important to recognize that USDC.e has a significant established presence on Polygon, with a large number of holders and substantial liquidity. Therefore, the migration to the native version affects a considerable user base. Both assets will coexist for a period, but their support structures are changing.
Action Required: What Users Need to Do
If you hold or use USDC on Polygon, understanding the distinction between the two versions is crucial. Your required action depends on how you interact with the asset.
Most importantly, Circle will stop supporting deposits and withdrawals of the bridged USDC.e through its Circle Mint platform and APIs after November 10, 2023. If you use these services, you must convert your USDC.e to the native version before this date to avoid potential loss of funds.
For general holders not using Circle’s direct services, your USDC.e balances remain safe. Major exchanges have stated they will continue to support the bridged version for the foreseeable future. However, always exercise caution: double-check tickers, contract addresses, and the type of USDC you are sending or receiving to prevent errors.

How Services Are Adapting to the Change
In response to Circle’s update, many crypto services, including exchanges and swap platforms, are updating their infrastructures to support native USDC on Polygon. This proactive shift ensures users will have continued access to the most updated and directly supported stablecoin version.
These platforms are future-proofing their services by integrating the new contract. Users of these services should expect a seamless transition where support for the bridged asset is phased out in favor of the native version. Always refer to official announcements from your service providers for specific instructions.
The Future of USDC on Polygon
The introduction of native USDC is a positive step for the Polygon ecosystem. It promises to enhance liquidity, reduce transaction friction, and attract more developers to build DeFi applications. Over time, the native version is expected to become the dominant standard.
This transition, while slightly complex in the short term, ultimately leads to a more efficient and user-friendly experience. The broader trend of stablecoin issuers directly supporting Layer-2 networks signals a maturation of the blockchain infrastructure, benefiting the entire community.
Frequently Asked Questions
What is the difference between USDC and USDC.e on Polygon?
USDC.e is a bridged version of the stablecoin that was brought to Polygon from Ethereum via third-party bridges. The new native USDC is issued directly by Circle on the Polygon network. The key difference is that Circle fully supports and redeems the native asset, while it only endorsed the bridged one.
Do I need to swap my USDC.e for native USDC?
If you use Circle’s services like Circle Mint, you must swap before the November 10, 2023 deadline. If you hold USDC.e on an exchange or in a private wallet and do not use Circle’s direct services, no immediate action is required, as exchanges will continue supporting it for now. However, migrating to the native version is recommended for long-term security.
How can I convert my bridged USDC to the native version?
You can convert USDC.e to native USDC using various decentralized exchanges (DEXs) or swap services available on the Polygon network. Always ensure you are using a reputable platform and verify the contract addresses of the tokens you are swapping to avoid scams.
Will USDC.e become worthless after the migration?
No, USDC.e will not become worthless. While Circle is ending its direct support, the asset will continue to be traded and supported by major exchanges and bridges. Its value is pegged to the U.S. dollar, just like native USDC, but its utility may become more limited over time.
Is native USDC better than the bridged version?
Yes, native USDC offers several advantages. It allows for direct redemption with Circle, eliminates bridging fees, and is integrated directly into Circle’s official products. It is generally considered the more secure and efficient option for users and developers.
Where can I find the contract address for native USDC on Polygon?
Always obtain contract addresses from official sources like Circle’s website or verified blockchain explorers to avoid counterfeit tokens. The official native USDC contract address on Polygon is a critical piece of information for any interaction.
