Sei official update: The Sei v6.4 upgrade has introduced a protocol-level switch to 'disable inbound IBC transfers.' This feature will be formally activated through a governance proposal in the future. If you hold any IBC assets on Sei, it’s recommended to bridge them back to their original chain as soon as possible before the proposal is passed. Otherwise, related Cosmos native assets will no longer be transferable to Sei, and users may face the risk of being unable to retrieve their assets. Assets that require immediate attention include: USDCet (Wormhole Ethereum USDC), USDCop (Wormhole Optimism USDC), USDTbs, ATOM, and WBTC. This adjustment is part of Sei’s effort to advance SIP-3 and transition the network to an 'EVM-only chain.' https://(wublock123.com)/news/sei-disables-ibc-inbound-transfers-migrate-cross-chain-assets-59725
