Layer-2 networks process transactions off Ethereum's main chain, and their ecosystems have rewarded early users generously, making them prime farming territory.

Bridge assets using the official bridge, then use apps on the layer-2 itself: swaps, lending, liquidity, NFTs, and governance participation.

Sustained, varied activity across months counts far more than a single large transaction or a burst of identical swaps in one day.

Prioritise networks with real usage and growing developer activity, and keep one or two speculative bets alongside proven chains.

Stay safe with dedicated wallets, official bridges only, and revoked approvals, and remember that no airdrop is ever guaranteed.
