Key Takeaways:
The ICON Foundation has set a final shutdown date of December 31, 2026, for its Layer 1 blockchain, capping a multi-month transition to fully migrate the ecosystem’s value and activity from its native ICX token to the new SODA token on the SODAX platform.
According to a series of official blog posts from the ICON Foundation, the wind-down process is staged to ensure users have ample time to move their assets. The foundation stressed that the ICON blockchain will remain live and accessible for the sole purpose of facilitating the 1:1 token migration via the official dashboard until the year-end deadline.
The phased shutdown has already passed several key milestones. On March 26, 2026, the network entered an “economic shutdown,” which halted all ICX emissions and staking rewards. A critical date for remaining holders is September 30, 2026, when two-way swaps between ICX and SODA will be disabled, leaving only a one-way migration path from ICX to SODA. After the final December 31, 2026 shutdown, any un-migrated ICX will be stranded on an inert, read-only chain.
This transition marks a fundamental shift in the network’s economic model, moving from the inflationary, emission-driven economics of the original ICON L1 to a fee-funded staking and pooling model on the SODAX protocol. For ICX holders, the message from the foundation is clear: the network's economic lifecycle is over, and the only path forward is migrating to SODA to participate in the new ecosystem before the final switch is flipped.
The migration is heavily incentivized by the launch of new reward structures on the SODAX platform. SODAX Stake and SODAX Pool went live on March 16 and March 31, 2026, respectively, with protocol fee-backed rewards commencing in early April. This creates a strong pull for users to migrate their assets, as all new value generation is now happening exclusively within the SODAX environment. The new SODA token will have a fixed maximum supply of 1.5 billion.
To reduce friction for users, major centralized exchanges are supporting the transition. Both Kraken and Coinone have announced they will facilitate the ICX to SODA migration for their customers, with Kraken also placing SODA on its public listing roadmap. This support from market infrastructure providers is critical for ensuring a smooth transition of liquidity. The ICON Foundation’s approach mirrors other recent shutdowns in the sector, such as those of Zero Network and Bit.com, which also set hard deadlines for migration, warning users that assets left behind could become permanently unrecoverable once the legacy infrastructure is decommissioned.
