A USDC balance on dYdX Chain would retain the same token identifier and user balance under a proposed software upgrade, even as its underlying support shifts from Noble USDC to Injective USDC. The proposal has not yet been approved.
In a report published on November 13, 2026, at 19:51 (+08:00), Foresight News said the dYdX Foundation had announced an on-chain vote on dYdX Chain software upgrade v9.9. The reported reason for the change is Circle’s planned discontinuation of USDC on Noble. Voting was set to close on November 16 at 19:32; if approved, the upgrade was expected to finish around November 18 at 01:00.
The proposal would add a Canonical USDC module and gradually change the asset supporting USDC on dYdX Chain from Noble USDC to Injective USDC. Once migration begins, USDC deposits would be accepted only through Injective. Deposits from Noble—including CCTP transfers routed through Noble—would be rejected and returned. Withdrawals could go to Noble or Injective, but not other chains.
After the Noble-backed portion is depleted, closing withdrawals to Noble would require governance approval. If on-chain USDC lacks sufficient backing, deposits and withdrawals would pause automatically; trading would not be affected, according to the reported proposal.
