Although there's no guaranteed way to be eligible for the Arbitrum airdrop, you can increase your chances by focusing on maximizing your activity, consistency, and reach within the Arbitrum ecosystem.
Here's a summary of the steps you can take:
Purchase Ethereum (ETH) through a centralized crypto exchange and transfer it to a software wallet (such as MetaMask) that supports ETH.
Connect the Arbitrum network to your MetaMask wallet.
Bridge your ETH from the Ethereum mainnet to the Arbitrum network.
Complete the guild on-chain quests to gain access to the Arbitrum guild.
Interact with Arbitrum frequently by using protocols that support it, such as GMX, Hop Protocol, Kyber Network, 1inch, and Shell Protocol. Consider making swaps, taking trades, adding liquidity, and staking in liquidity pools.
