Hyperliquid led weekly blockchain fee revenue, according to the source, underscoring how vertical chains (blockchains built for specific use cases) are becoming more prominent in the digital asset market. Fee revenue is often watched as a measure of real network usage because it reflects what users are willing to pay to access trading, settlement, or other onchain services. The mention of Hyperliquid suggests strong activity around its ecosystem, while the broader reference to vertical chains points to growing interest in networks designed around a narrow function rather than a general-purpose blockchain model.
