Sei Labs Sets June 15 Deadline for Exchange EVM Migration

Sei Labs has mandated that all cryptocurrency exchanges complete migration from native Sei addresses to EVM addresses by June 15, 2026, with the threat of fund loss for non-compliance. The blockchain has automatically paired each native sei1 address with an equivalent EVM 0x address, offering four migration pathways to accommodate different technical capabilities.

Sei Labs' migration deadline represents a significant infrastructure transition for the Sei blockchain ecosystem. The shift from native Cosmos addresses to EVM compatibility signals the project's strategic pivot toward Ethereum Virtual Machine standards, likely driven by the need to enhance interoperability and attract developers familiar with EVM tooling. This move aligns with broader industry trends where multi-chain architectures increasingly prioritize EVM standardization as a means to bridge liquidity and developer ecosystems.

The 18-month deadline provides sufficient runway for exchanges to implement necessary technical changes, though the penalty structure—potential fund loss—creates genuine urgency. By automatically generating paired EVM addresses for all native addresses, Sei Labs has simplified the initial phase, reducing friction for users and institutions. The availability of four distinct migration paths suggests thoughtful planning to accommodate varying levels of technical sophistication, from fully automated smart contract solutions to manual transfers.

For exchange operators and institutional participants, this migration creates operational overhead and testing requirements during a competitive market period. The deprecation of Cosmos RPC endpoints will force ecosystem-wide compliance, eliminating gradual phase-out possibilities. Market impact depends on migration execution quality—smooth transitions preserve user confidence while technical failures could trigger liquidity concerns. The deadline also incentivizes developers to build robust bridging solutions and migration tools ahead of June 2026.
