Arbitrum is a Layer 2 (L2) network for scaling the Ethereum blockchain, developed by Offchain Labs. It uses Optimistic Rollup technology to aggregate large packets of off-network transactions from Ethereum smart contracts and decentralized applications (DApps) before sending them to Ethereum.

Analytics firm Arkham Intelligence said that bankrupt hedge fund Alameda Research, part of the FTX Group, was able to get more than 33 000 ARB tokens worth $45 000 in the airdrop held on March 23.

gmAlameda accounts have so far claimed a combined 33125 $ARB from the Arbitrum airdrop, with one account, 0xc5e, receiving the maximum allocation of 10250 ARB.Combined, that's around $45K at current prices!It's probably a good thing that they're not allowed to trade it... pic.twitter.com/cz3L2HtzCH — Arkham (@ArkhamIntel) March 30, 2023

Previously, Arkham Intelligence warned that participants in the ARB airdrop were at risk of losing their funds. The day before, experts recorded suspicious activity on the network and noted that a hacker could implement a scheme to automatically redirect funds to his address using a smart contract.

On March 23 Arbitrum’s online resources stopped working due to a high influx of users. The project team stated that participants of the airdrop would have six months to claim their tokens.

As of March 31, 12:25 UTC, the ARB token is trading at $1,35, over the past day the value of the asset has decreased by 2,22%, according to aggregator CoinGecko.
