Over the past couple of years, we've seen a surge in Layer 2 blockchain solutions, each offering unique technologies and solutions. Some notable ones include Base, Dymension, Blast, Linea, Starknet, Metis, Manta, zkSync, Sui, and Aptos, among others. This proliferation of options is beneficial for the DeFi ecosystem, providing builders with diverse opportunities to create applications that cater to user needs.

The growth in the number of unique addresses interacting with Layer 2 chains in 2024 compared to 2022 reflects the increasing adoption of these solutions. To make the most of these new chains and their offerings, such as applications, reward programs, incentives, mainnet launches, and token generation events (TGEs), it's essential to stay informed and attentive.

Despite newer chains often grabbing attention on platforms like Crypto Twitter, older Layer 2 chains like Arbitrum continue to exhibit resilience and maintain strong asset positions. Monitoring metrics such as total deposits, DeFi total value locked (TVL), decentralized exchange (DEX) volume, and stablecoin activity can help identify promising opportunities within Layer 2 ecosystems.

Analytical tools like Defillama can aid in tracking net flows and understanding the reasons behind liquidity movements. Finding a niche interest, whether it's exploring established Layer 2 solutions like Optimism and Arbitrum or delving into newer chains like Base and Blast, can provide early access to potential gems and future airdrop opportunities.
