As a follow-up to our initial announcement on March 5, 2025, we are writing to confirm an upcoming change to the way we handle the USDC ticker in Network Data Pro (NDP) and Atlas. Please be aware that this upcoming change will not impact our Reference Rates, Market Data Feed or Indexes. This change will go live on September 8, 2025.
What’s Changing
For Network Data Pro clients:
- The ticker USDC will no longer represent USDC on Ethereum only. Instead, it will become an aggregated ticker for natively issued USDC across all supported networks in our coverage universe.
- A subset of metrics that cannot be aggregated will no longer be supported for the aggregated USDC ticker. You can find this list of deprecated metrics here.
- USDC_ETH remains unchanged and continues to provide full USDC on Ethereum-specific metrics.
For Atlas clients:
- The ticker USDC will no longer be supported as of September 8, 2025.
Client Action Required
For Network Data Pro clients:
- To view Ethereum-only USDC metrics, ensure you are querying the USDC_ETH ticker.
- To view aggregate metrics across all supported chains, you should use the USDC ticker.
- If you are using the aggregated USDC ticker, please confirm that the metrics you are querying are supported for aggregation. You can find the list of deprecated metrics here.
For Atlas clients:
- Queries using USDC will stop working after September 8, 2025. Please update to the appropriate chain-specific ticker (e.g., USDC_ETH).
If you have any questions or need support transitioning queries ahead of the change, feel free to reach out to us. We’re here to assist you every step of the way.
