Coinbase’s Aug. 17 cutoff for USDC on the Noble network has already passed, yet Circle’s public onboarding guide continues to tell users they can buy USDC on Coinbase, leaving a live documentation gap for anyone following the instructions after the deadline.
The Aug. 17 Noble USDC cutoff is now in the past
Coinbase ended its support for USDC on the Noble network as of Aug. 17, a date that has now passed as of this writing on Aug. 18. The change was reported as a discontinuation of Noble network support on the exchange. For related coverage, see Coinbase Secures Abu Dhabi License for Tokenized Securities.
This is not a countdown to a future deadline. The relevant question is no longer what happens on Aug. 17, but what happens to users who consult purchase instructions after the cutoff has already taken effect.

Anyone checking onboarding steps today could be pointed toward a route that no longer matches how Coinbase handles USDC on Noble. That timing mismatch is the core of the story.
Circle’s guide still points users to Coinbase
Circle’s public guide on how to get USDC on Noble still directs users to buy USDC on Coinbase, according to reporting that the instruction remained live after the cutoff date passed. The instruction appears in Circle’s learn resource for acquiring USDC on Noble.
The inconsistency is straightforward: one fact says Coinbase’s Noble USDC support ended Aug. 17, and the other says Circle’s guide still tells people to use Coinbase for that purpose. Circle also maintains a broader multi-chain USDC page covering Noble.
A user reading the guide at face value could reasonably attempt the Coinbase route without knowing the exchange has already changed how it handles the network. This article is highlighting that documentation gap, not offering a replacement set of instructions.
Why stale instructions matter for USDC users
A passed cutoff paired with unchanged instructions can cause confusion, wasted steps, or failed expectations for people trying to move USDC across networks. Crypto users frequently rely on official public guides as the authoritative reference for transaction steps.
Time-sensitive operational changes only stay useful when the surrounding documentation is updated to match. Readers who want the underlying mechanics of the token can review how USDC reserves, minting, and supported chains work for context on why network support details carry weight.
The pattern also echoes other recent deadline-driven changes across the Coinbase ecosystem, including the separately reported Aug. 15 CyberWallet and Passkey Wallet withdrawal cutoff, where timing and user notice were central. It arrives the same week Coinbase leadership is set to meet with policymakers on Aug. 19.
The narrow takeaway is a guide-update gap: until Circle’s public instructions reflect Coinbase’s post-Aug. 17 handling of USDC on Noble, users following the guide may be acting on outdated guidance.
