To participate in Arbitrum's new airdrop plan (as of March 17, 2025), eligibility likely requires active engagement on Arbitrum One or Nova, such as bridging funds, frequent transactions, or dApp interactions—based on past criteria. Check the official Arbitrum Foundation site for updates, as no specific plan is confirmed yet. To maximize yield, use multiple wallets for diversified activity, stake ARB tokens, provide liquidity on DEXs like GMX, and monitor snapshot dates. Stay updated via X posts and avoid Sybil detection by varying transaction patterns. Details remain speculative until officially announced.
