USDC.n is being deprecated on the supported Cosmos chains, with USDC.inj becoming the supported version going forward.
The migration through Skip:Go is pretty straightforward:
Skip:Go handles the intermediate steps automatically. After the first signature, you typically wait around 3–5 minutes before the second signature. You also don't need to prepare INJ beforehand
Skip:Go can automatically recharge the required amount if your INJ balance isn't enough for the second transaction.
If you're holding USDC.n on dYdX, Cosmos Hub, Osmosis, Terra 2.0, Neutron, ZIGChain, Initia, or Xpla, this migration is worth checking.
USDC.n is moving out. USDC.inj is the version to use going forward.
