What is Layer 2 scaling and how does it reduce transaction fees?

Layer 2 solutions like Arbitrum process transactions off the main Ethereum blockchain, easing congestion. Arbitrum uses optimistic rollups to bundle and process many transactions together off-chain before settling them on Ethereum. This means users pay much lower gas fees, splitting costs across transactions. ETH is still used for gas fees, so you'll need to bridge ETH to Arbitrum.

How can one participate in an Arbitrum token airdrop?

The main Arbitrum airdrop happened in 2023 for early users. Eligibility depended on using Arbitrum services before certain dates, like bridging funds or using DApps. Future airdrops may reward active users, so regular use of Arbitrum and its DApps can help your chances. Some projects also do their own airdrops.
