Key Highlight
- Coinbase will discontinue USDC deposits and withdrawals on the Noble network effective August 17, 2026.
- USDC sent to Coinbase on Noble after the cutoff will be permanently unrecoverable.
- USDC support will continue on Ethereum, Base, Solana, Arbitrum, Optimism, and Polygon without changes.
Coinbase, a publicly traded cryptocurrency exchange, has announced that it will discontinue support for USDC deposits and withdrawals on the Noble network effective August 17, 2026. The decision affects only the Noble blockchain, while USDC will remain fully supported across Ethereum, Base, Solana, Arbitrum, Optimism, and Polygon. The exchange has urged users to update their transfer practices before the cutoff to avoid permanently losing funds.
According to the official announcement from Coinbase Markets, starting August 17, customers will no longer be able to send or receive USDC on the Noble network through Coinbase.
Any USDC sent to Coinbase deposit addresses on Noble after the cutoff date will not be recoverable. The exchange said the warning applies to all users transferring USDC through Noble.
Other networks remain operational
Ethereum and its layer-2 solutions (Base, Arbitrum, and Optimism), along with Solana and Polygon, will remain primary channels for USDC activity on the exchange. Users relying on these networks should experience no disruption.
Noble is a blockchain built using the Cosmos SDK, primarily known for facilitating native USDC issuance and transfers within the Cosmos ecosystem. However, centralized platforms like Coinbase periodically review and adjust supported networks based on usage, security considerations, liquidity, and operational priorities.
What users need to do
For individuals and businesses using Noble for USDC transfers, the change means assets should be moved to another supported network before the August 17 deadline. Sending USDC to Coinbase deposit addresses on Noble after support ends could result in permanent loss of funds.
Coinbase advised users not to send USDC to Noble deposit addresses after the cutoff date and directed customers with questions to its Help Center for additional guidance.
While Noble has carved out a niche in the Cosmos ecosystem, its lower overall volume compared to dominant networks like Ethereum and Solana may have influenced the decision.
USDC isn’t going anywhere
USDC, issued by Circle, is one of the most widely used dollar-pegged stablecoins, prized for its regulatory compliance and transparency. Its availability across multiple blockchains has been a key growth driver. Coinbase’s decision does not impact USDC’s underlying value or Circle’s issuance but rather reflects a shift in how one major on-ramp and off-ramp handles a specific network.
As the crypto industry evolves, exchanges continue to review supported assets and blockchain networks, discontinuing those that no longer align with operational or business priorities.
Coinbase reopens for Mainland China in a policy shift
In another move towards a policy shift, Coinbase has reopened account registration for individuals in mainland China. The move allows new users to create accounts and complete identity verification using passports, according to the exchange’s updated customer support documentation.
The change, first noted on July 14, 2026, represents a departure from Coinbase’s previous restrictions on mainland China. Following China’s aggressive crackdown on cryptocurrency trading and mining activities in recent years, the exchange had largely barred users in the region from signing up.
