ICON blockchain to shut down on 31 December 2026

The ICON blockchain is scheduled to permanently shut down on 31 December 2026, at which point it will transition into a read-only archive. The project, which launched in 2017 as a layer-1 network designed to connect various blockchains, is being folded into SODAX, a cross-network execution and liquidity system.

Token holders must migrate their ICX to SODA, an ERC-20 token on the Sonic blockchain, at a 1:1 ratio. There are two critical deadlines for this process: the two-way swap between ICX and SODA will close on 30 September 2026, after which only one-way conversions from ICX to SODA will be possible. After 31 December 2026, no further conversions can be made.

Major exchanges like Kraken have already completed automatic migrations for their users. However, individuals utilizing self-custody wallets must use the official migration portal. Those performing manual migrations on the Sonic blockchain will require S tokens to cover gas fees.
