ICON blockchain shutdown set for Dec 31, 2026 - swap ICX to SODA now
Somewhere in an old exchange account or a forgotten hardware wallet, plenty of crypto holders are still sitting on ICX, the token that rode the 2018 altcoin boom into the top 30 by market cap. That holding is about to become a lot harder to ignore. The ICON blockchain shutdown is now official, and the foundation behind the project has set a hard countdown for anyone who wants to save what they own before the chain goes dark for good.
Key takeaways
- The ICON blockchain will permanently shut down on 31 December 2026 and become a read-only archive with no new blocks.
- ICX converts to SODA at a 1:1 ratio, with SODA issued as an ERC-20 token on the Sonic blockchain.
- Two-way swaps end on 30 September 2026; after 31 December 2026 no conversion is possible at all.
- Kraken already completed the ICX-to-SODA migration for its users automatically between 10 and 14 August 2026, and SODA began trading worldwide on the exchange against USD and EUR.
- ICON has been at an economic standstill since 26 March 2026, with issuance and staking rewards discontinued.
ICON Blockchain Shutdown and Migration Deadlines
The countdown to the ICON blockchain shutdown comes down to two dates, and mixing them up is the easiest way to lose access to your tokens. ICON launched in 2017 as its own layer-1 network built to connect other blockchains, producing technical standards such as the BTP transfer protocol and the xCall cross-network interface along the way. Nine years later, the foundation behind it has concluded that running an independent chain no longer serves that goal, and it is folding the project into SODAX, a cross-network execution and liquidity system.
