The dYdX Foundation said an on-chain vote had begun on a proposed dYdX Chain v9.9 upgrade. The change 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 users’ balances unchanged. The proposal follows Circle’s planned discontinuation of USDC on Noble.
For anyone reading the ledger, the distinction is between the USDC balance recorded on dYdX Chain and the asset supporting that balance. An unchanged token identifier or balance would not, by itself, show which route supports a deposit or withdrawal.
According to the Foundation, 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 no longer to other chains. Closing withdrawals to Noble after its supporting balance is cleared would require governance approval. If on-chain USDC were not fully supported, deposits and withdrawals would pause automatically; trading would be unaffected.
The Foundation said voting would end on November 16, 2026, at 19:32. If approved, the upgrade was expected to be completed around November 18, 2026, at 01:00. The source did not specify time zones for those two times.
