The Base network receives a hard fork on Tuesday, September 30, 2026, at 18:00 UTC. It is called Cobalt, and for you as a holder it means one thing above all: deposits and withdrawals over Base will stand still for some time that evening. Binance has announced the freeze from 17:00 UTC, an hour before the switch. Trading continues; only transfers between the exchange and your own wallet pause. Your tokens do not disappear in the process, they are not swapped, and no second coin appears. If you want to move something over Base that evening, do it beforehand or wait until the next morning.
The real stumbling block lies elsewhere: the exchange resumes transfers without further announcement as soon as the network is running stably. There is no starting gun you could wait for — you have to look yourself. This article sets out what actually happens in a hard fork, why exchanges regularly cut the bridge at such moments, and what the date means for your balance, your holding period and your own node.
