The dYdX Foundation said an on-chain vote is underway on dYdX Chain software upgrade v9.9. The proposal would add a Canonical USDC module as Circle prepares to discontinue USDC on Noble. It would gradually shift the asset supporting USDC on dYdX Chain from Noble USDC to Injective USDC, while leaving the on-chain USDC token identifier and user balances unchanged.
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 either Noble or Injective, but not to other chains. After the Noble-backed portion is cleared, withdrawals to Noble would be shut off subject to governance approval.
If on-chain USDC lacks sufficient backing, deposits and withdrawals would pause automatically; trading would not be affected. According to the foundation’s statement reported by ChainCatcher, voting was set to close on November 16 at 19:32. If approved, the upgrade was expected to be completed around November 18 at 01:00. Those were plans, not confirmation that the upgrade had taken place.
