Ethereum’s Layer 2 network experienced a surge in mainnet payment fees in May, reaching nearly 9,000 ETH worth $16.2 million.
This is a fivefold increase from the total fees paid by Layer 2 in January, largely due to soaring gas costs on the Ethereum mainnet.
Among them, Arbitrum became the main contributor to the main network payment fee, generating a cost of 4260 ETH, which is about 7.6 million US dollars. zkSync’s Era mainnet came in second with 2,250 ETH, or roughly $4 million.
