ICX to SODA Migration: 1.109 Billion ICX Still Sit on the ICON Chain, and Neither Chain Shows a Swap Count

If you hold ICX in your own wallet, you have until September 30, 2026 to use the swap into SODA in both directions, and until December 31, 2026 to start it at all. After that the ICON blockchain will be shut down. The obvious question ahead of a deadline like this one: how far has the swap actually progressed? The answer from this analysis is an uncomfortable one, and it matters more for your decision than any percentage figure would: there is no public progress indicator, and none can be derived from the two blockchains either. Something else is measurable, and that is what we measured.

On the ICON chain, 1,108,792,074.22 ICX were still sitting there on September 1, 2026 at 10:02 UTC. On the Sonic chain, the SODA contract reports a total supply of 1,499,555,266.83 SODA. We retrieved both figures ourselves. Neither of them moves the way it would have to move if the swap were reflected in it. What that means for you is set out further down in three concrete steps.

What a token migration means technically

A token migration is the relocation of a holding from one blockchain to another: the old token is surrendered or locked, and the new one is credited in the same amount. In ICON's case the swap runs at a 1:1 ratio, and the new token is an ERC-20 token, a token following the widely used Ethereum standard, which here sits on the Sonic chain. We already covered the mechanics, the deadlines and the tax side in detail once the dates were fixed: Swap ICX for SODA, two deadlines before the ICON blockchain shuts down. This article does not repeat any of that. It takes measurements instead.
