Holders of Solana USDC on Sei Need to Act Before IBC Is Disabled
Sei's recent upgrade to v6.4 included the mechanism to disable the transfer of IBC assets. If you've bridged Solana USDC to Sei, here's what's next
As of this posting, there is approximately $245k in USDC bridged from Solana (USDCso) via Wormhole on Sei Network. If you hold any Solana USDC, you should bridge it out before the governance proposal to disable inbound IBC transfers passes.
This is part of the broader SIP-3 transition for upgrading the Sei Protocol into an EVM-only chain. To clarify: v6.4 has only shipped the protocol-level ability to disable inbound IBC transfers, but holders should bridge now.
Once the follow-on governance proposal activates this change, assets like USDC.so will no longer be bridgeable into Sei, and holders may lose access to their assets.
If you're a holder of Solana USDC on Sei, here are your options:
Bridge out
You can bridge your USDCso back to Solana using a frontend like Skip:Go or a Wormhole-compatible bridge interface. From Solana, you can use the asset natively or bridge to another chain. The mention of this platform does not constitute an endorsement, and users should do their own research before using any third-party service.
For suppliers of USDCso on DeFi protocols
If you have USDCso supplied on any DeFi protocol on Sei, you should first wind down those positions and withdraw them before bridging out. Failure to do so before the governance change may result in the inability to access your supplied assets.
