Sei's v6.4 upgrade enables IBC transfer disabling as part of EVM transition. $245K in Solana USDC at risk if holders don't act before governance vote.

Sei Network Warns Solana USDC Holders to Bridge Out Before IBC Shutdown

Sei Network is urging holders of Solana-bridged USDC to move their assets off the chain immediately. The network's v6.4 upgrade has enabled the mechanism to disable inbound IBC transfers, and a governance proposal to activate this change is pending. Approximately $245,000 in USDC bridged from Solana via Wormhole currently sits on Sei.

The clock is ticking for affected users. Once the governance proposal passes, assets like USDCso won't be bridgeable into Sei anymore—and holders who haven't acted could lose access entirely.

What's Actually Happening

This move is part of SIP-3, Sei's broader transition to become an EVM-only blockchain. The v6.4 upgrade didn't flip the switch yet; it just installed the mechanism. But the follow-on governance vote will activate the change, making this a matter of when, not if.

The timing matters. Circle has been aggressively expanding USDC on Solana—minting 750 million USDC on the network within a 24-hour period just yesterday, April 14. Solana currently hosts over $9 billion in USDC circulation. But that liquidity won't help Sei users once IBC transfers get disabled.

Your Options Right Now

If you're holding USDCso on Sei, you've got one real path forward: bridge out. Sei recommends using Skip:Go or any Wormhole-compatible bridge interface to move assets back to Solana, where you can use them natively or bridge elsewhere.

DeFi users face an extra step. If you've supplied USDCso to any lending protocol or liquidity pool on Sei, you need to unwind those positions first. Withdraw your assets, then bridge. Leaving supplied assets in DeFi protocols after the governance change passes could mean permanent loss of access.

The Bigger Picture

Sei's EVM-only pivot represents a significant architectural shift. The network is essentially cutting ties with Cosmos-style IBC connectivity in favor of Ethereum Virtual Machine compatibility. For users holding bridged assets from non-EVM chains like Solana, this transition creates a narrow window to exit.

The $245,000 at risk isn't a massive sum by crypto standards, but it's real money for the individuals holding it. And the governance proposal could pass quickly once submitted.

Affected users should check Sei's SIP-3 migration guide or hit up their Discord for specific questions. The window to act won't stay open indefinitely.
