Starknet (STRK) had been falling until the upgrade activated, then shot up almost 10%, erasing earlier losses. It was recently 6% higher over 24 hours. Starknet posted on X that it already submitted its first batch of data in a “blob” that benefits from the reduced fees Dencun makes possible. The Starknet Foundation, an organization behind the network’s development, also laid out plans on Tuesday for further cost reductions for users.
