dYdX holders are voting on an upgrade that would change what backs every dollar of USDC on dYdX Chain, about 67.9 million of it, moving the backing from Noble to Injective before Circle shuts USDC on Noble down in January. Proposal 400, which installs the v9.9 software, had cleared quorum by Saturday with just over 90% of votes cast in favor, and the switch is targeted for Nov. 17. Balances and open positions stay as they are, but the way traders get money in and out of the exchange changes on upgrade day.
Why the move is happening
USDC on dYdX Chain has always arrived through Noble, a Cosmos chain built to issue Circle’s stablecoin natively for the IBC network. In September, Circle said it was discontinuing support for USDC and its legacy CCTP V1 bridge on Noble, noting that “Noble will not receive CCTP V2.” New minting on Noble stopped on Oct. 13, burn limits began shrinking on Oct. 31, and Circle will fully pause the Noble USDC contract and its CCTP routes on Jan. 12, 2027, before opening a manual redemption process for remaining holders.
Injective remains an active Circle partner, Circle said in the same post, which makes it the obvious replacement inside the Cosmos network. Noble’s role as the main USDC gateway for IBC chains is ending in the same month that stewardship of IBC itself moved to the Linux Foundation.
What v9.9 changes
The upgrade adds a module called x/canonicalusdc, according to the v9.9.0 release notes. USDC on dYdX keeps its existing token identifier, which still carries a Noble label in wallets and explorers, while the module records whether each unit is backed by Noble USDC or Injective USDC.
From the upgrade height, deposits arrive only through Injective. Deposits from Noble, including CCTP transfers routed through Noble and Noble auto-forwarding addresses, will be rejected and refunded on Noble. Withdrawals leave as Injective USDC, or as Noble USDC while that route stays open. USDC can no longer be withdrawn directly to other chains such as Osmosis.
The dYdX team flagged two traps. USDC from Injective sent to dYdX before the upgrade is not converted and “can’t be used as collateral,” so it has to be sent back and deposited again. And because Injective backing starts at zero, larger withdrawals to Injective may be rejected in the first days while deposits build it up.
A safeguard checks every block that USDC on the chain is fully backed. If it finds a shortfall, deposits and withdrawals pause automatically while trading continues. Informal Systems audited the module from Nov. 2 to 9, and dYdX said all reported findings were fixed.
How fast the Noble backing can clear
Noble backing shrinks only when USDC is withdrawn to Noble. Most of that work falls to a designated operator that withdraws to Noble and redeposits through Injective, over and over, until nothing is left. The blog says the pace depends on that operator and on rate limits, “not on user activity.”
Those limits are tight against the amount involved. Withdrawals on both routes count toward a shared cap of $1 million an hour and $10 million every 24 hours, the dYdX blog says. The chain’s bank module showed 67,880,700 USDC under the Noble-labelled denomination on Saturday. If the operator’s withdrawals draw on the same cap as everyone else’s, clearing that balance would take about seven days of maximum use, longer if traders are withdrawing too. Circle’s per-transaction CCTP V1 burn limit on Noble, currently $250,000 and falling, adds another constraint.
The calendar adds pressure. A follow-up vote to close Noble withdrawals is expected in early December. After Dec. 1, Circle has warned, CCTP exits from Noble may be limited to destinations that still support V1 burns.
Where the vote stands
The proposal went on-chain on Nov. 13, the same day the dYdX Operations subDAO posted it on the dYdX forum for community feedback. On Saturday, about 161.4 million DYDX had voted yes and 17 million abstained, a turnout of roughly 57% of bonded tokens against a 50% quorum. No-with-veto votes totaled 31 DYDX, and plain no votes were zero. Voting closes on Nov. 16, and the upgrade is set for block 114,220,000, which dYdX expects around 17:00 UTC on Nov. 17, though changes in block times can move that.
FAQ
Do dYdX traders need to do anything with USDC already on the exchange?
No. dYdX says balances, open positions and collateral are unaffected. Traders will need an Injective address to receive withdrawals after the upgrade.
What happens if I deposit USDC from Noble after Nov. 17?
The deposit is designed to be rejected and refunded to the sending address on Noble. Deposits need to come through Injective once v9.9 is live.
When does Circle stop supporting USDC on Noble?
Circle will fully pause the Noble USDC contract and CCTP routes on Jan. 12, 2027, take a snapshot of remaining balances and open manual redemptions from Jan. 13.
