<Danger>
  **Action required: IBC assets on Sei will become inaccessible**

  If you hold [USDC.n](https://seiscan.io/address/0x3894085Ef7Ff0f0aeDf52E2A2704928d1Ec074F1) (USDC via Noble), [USDT.kava](https://seiscan.io/address/0xb75d0b03c06a926e488e2659df1a861f860bd3d1) (Kava USDT), Wormhole-bridged tokens, or any other IBC asset on Sei, you **must** swap, migrate, or bridge out **before the governance proposal to disable inbound/outbound IBC transfers passes and is activated** to avoid permanent loss of access. After this, Sei will no longer support IBC bridging of assets from Cosmos-based chains to and from Sei Network.

  Consult the [SIP-03 Migration Guide](/learn/sip-03-migration) for the full list of affected assets, required actions, and supported routes.

  For USDC.n specifically, see: [Holders of USDC.n Need to Swap or Migrate](https://blog.sei.io/announcements/holders-of-usdcn-need-to-swap-or-migrate/).
