Airdrop hunters have been flocking to the Arbitrum layer-2 network in hope of landing some free crypto.

On Nov. 2, crypto research firm Delphi Digital reported an increase in activity on Arbitrum. It stated that 62% of this week’s Ethereum transactions have been on Arbitrum, marking a 550% surge since August.

It added that weekly active users on Offchain Labs’ platform have also spiked in October. Since Oct. 10, weekly active users have grown 125% to reach a new all-time high of 282,000, it noted.

“Much of the activity is likely from speculators trying to boost their on-chain activity in the hopes of receiving a larger airdrop.”
