Tron is once again No. 1 in revenue among all blockchains
According to DefiLlama, Tron ranks first in revenue over the past 24 hours, 7 days, and 30 days—by a wide margin over other networks.

Over the past month, the network generated around $23.4–23.9 million. For comparison, Ethereum generated approximately $6.3–6.4 million, and Solana around $3.4 million.
The main driver is the high volume of stablecoin transfers (primarily USDT).
