PANews reported on February 27th that Coinbase announced on its X platform that Sei plans to discontinue support for Cosmos-based trading and switch to an EVM-only architecture. Coinbase will support the migration to the Sei EVM from April 6th to 8th, 2026. During the migration, sending and receiving Sei (SEI) will be temporarily disabled, and users are advised not to deposit or transfer SEI during this period. Users' tokens will be converted at a 1:1 ratio, with no conversion fees. If users wish to opt out of automatic conversion, they must send their SEI to a compatible self-custodied wallet before April 6th, 2026. After the migration is complete, users can only withdraw SEI to an EVM-compatible address (0x format) and deposit SEI from an EVM-compatible wallet. Coinbase will no longer support depositing SEI to bech32 (Cosmos) deposit addresses.
