dYdX has initiated an on-chain vote for its v9.9 protocol upgrade, scheduled to run through November 16. If approved, the upgrade will execute at block height 114220000 around 17:00 UTC on November 17, migrating USDC reserves from Noble to Injective in response to Circle discontinuing USDC support on the Noble network. Following the transition, all new deposits must route through Injective, while any deposits made via Noble will be automatically returned. Existing user balances and trading positions remain unaffected, and withdrawals can continue through either Noble or Injective during the migration period.
