Deprecation NoticeCosmos SDK and CosmWasm functionality is being deprecated in favor of EVM-only. For more details, see SIP-3 and Proposal 99.In addition, Proposal 115 disables CosmWasm code uploads (MsgStoreCode) and contract instantiations (MsgInstantiateContract) chain-wide. No new CosmWasm contracts can be deployed; only execute and query against pre-existing contracts remain available via the CosmWasm precompile.IBC is now disabled in both directions. Proposal 116 and Proposal 120 set the ibc module’s InboundEnabled parameter to false, and Proposal 121 set OutboundEnabled to false on July 31, 2026. No asset can be bridged into or out of Sei over IBC, and IBC assets already on Sei can no longer be redeemed on their origin chain. See the SIP-03 Migration Guide for the full explanation and the list of affected assets.

Tokenfactory is not supported

Tokenfactory tutorials and development support have been retired as part of Sei’s move to EVM-only under SIP-3. Do not create, mint, burn, administer, or build integrations around tokenfactory denoms. Legacy module and RPC surfaces may still exist for compatibility, but tokenfactory is not a supported path for new development. Deploy an ERC-20 contract instead.
