dYdX plans to upgrade to v9.9, and the on-chain USDC supported assets will be converted from Noble USDC to Injective USDC

The dYdX Foundation announced on platform X that it has initiated an on-chain vote for the dYdX Chain software upgrade v9.9, which will end on November 16 at 19:32. Due to Circle decommissioning USDC on Noble, this upgrade will introduce a Canonical USDC module, gradually transitioning the underlying supported asset for USDC on the dYdX Chain from Noble USDC to Injective USDC, while the token identifier and user balances for on-chain USDC will remain unchanged.

After the migration begins, USDC deposits will only be supported through Injective, and deposits from Noble (including CCTP transfers routed through Noble) will be rejected and returned; USDC withdrawals can choose between Noble or Injective, and withdrawals to other chains will no longer be supported.

Once the Noble-supported portion is cleared, withdrawals to Noble will be closed upon governance approval. If on-chain USDC does not receive sufficient support, deposits and withdrawals will be automatically suspended, but trading will not be affected. If the vote passes, the upgrade is expected to be completed around November 18 at 01:00.
