The dYdX Foundation said a vote was underway on the proposed dYdX Chain v9.9 software upgrade. In a report published on November 13, 2026, at 20:06 (UTC+8), ChainCatcher said the vote was set to end on November 16 at 19:32. If approved, the upgrade was expected to be completed around November 18 at 01:00. The report did not specify a time zone for those two scheduled times.
The proposal responds to Circle’s planned discontinuation of USDC on Noble. It would add a Canonical USDC module and gradually shift the asset supporting USDC on dYdX Chain from Noble USDC to Injective USDC. The USDC token identifier and users’ on-chain balances would remain 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 would be available through Noble or Injective, but not to other chains. After the Noble-backed portion is depleted, withdrawals to Noble would be disabled subject to governance approval.
If USDC on dYdX Chain is not fully backed, deposits and withdrawals would pause automatically; trading would not be affected. These are proposed changes, not changes the November 13 report said had already taken effect.
