Wallet Drops a Network: How to Rescue Your Coins Before the Deadline

Your wallet has stopped showing a coin, and the app has put a date on the screen. The good news first: your balance is not gone. It sits on the blockchain, and the blockchain keeps running. What you lose is the convenient way in through that one app, and that can be replaced as long as you still have your recovery phrase.

The next case falls on September 24, 2026: Phantom is ending support for the Sui network. It is the fifth shutdown of this kind in four weeks. This article explains what actually happens at a technical level, which two routes you have before any such deadline, where the move most often goes wrong in practice, and what German tax law has to say about it.

What happens to your coins when a wallet drops a network?

Technically, nothing at all happens to your balance. A self-custody wallet stores no coins. What it holds are the private keys you use to sign transactions on a blockchain, and its interface shows you what the chain assigns to your address. When a provider drops a network, it switches off the display and the signing function for that network. The chain itself, your address and your holdings stay exactly as they were.

Phantom puts it plainly on its own help page for the Sui case: "Your assets are not lost. They remain on the Sui blockchain and can be accessed using a compatible wallet with the same credentials."
