Holders of Wormhole-Bridged WETH 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 WETH to Sei using Wormhole, here's what's next

Holders of Wormhole-Bridged WETH on Sei Need to Act Before IBC Is Disabled

As of this posting, there is approximately 62 WETH ($133k) bridged from Ethereum via Wormhole on Sei Network. If you hold any Wormhole WETH, 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, Cosmos-native assets like Wormhole WETH will no longer be bridgeable into Sei, and holders may lose access to their assets.

If you're a holder of Wormhole WETH on Sei, here are your options:

Bridge out

You can bridge your Wormhole WETH back to Ethereum using a frontend like Skip:Go or a Wormhole-compatible bridge interface. From Ethereum, you can unwrap, swap, or use the asset natively. The mention of this platform does not constitute an endorsement, and users should do their own research before using any third-party service.

For users with WETH in DeFi positions

If you have Wormhole WETH supplied or deposited in any DeFi protocol on Sei, including lending markets and liquidity pools, 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.
