Wu said that according to the @on_datawarlock data panel, Arbitrum became one of the biggest winners of the LayerZero airdrop. The mandatory donations for the LayerZero airdrop brought Arbitrum congestion and pushed up the network gas fee. On June 20, Arbitrum rollup revenue reached $3.43 million, with a net profit of $3.29 million, setting a record high for a single day. The @hildobby_ data panel shows that after the LayerZero airdrop was opened, the median Arbitrum gas fee once soared to nearly 35 gwei.
