Fact Check

The official @CoinbaseMarkets X thread (July 15, 2026) explicitly states Coinbase will end support for USDC deposits and withdrawals on the Noble network on August 17, 2026, and that users will no longer be able to send or receive USDC on the Noble network after that date. This is a first-party primary source that matches the claim exactly, and it is corroborated by the PANews report which cited the same post.

Summary

Coinbase said it will discontinue USDC deposits and withdrawals on the Noble network on Aug. 17, 2026, ending support for that transfer route on the exchange while keeping USDC available on Ethereum, Base, Solana, Arbitrum, Optimism and Polygon. The company warned that any USDC sent to Coinbase deposit addresses on Noble after the cutoff will be permanently unrecoverable, making it important for users and businesses to shift transfer activity before the deadline. Noble, a Cosmos SDK-based blockchain known for native USDC issuance and transfers in the Cosmos ecosystem, will not lose USDC itself as a result of the move; the change affects only Coinbase’s support for that network.
