Metis is an Ethereum Layer-2 scaling solution designed to overcome the blockchain trilemma, which states that blockchains cannot be decentralised, safe, and scalable at the same time. It also aims to address Ethereum's major concerns, including speed, cost, and scalability.
Metis has begun a Layer3 quest campaign in which users who complete mainnet quests will gain XP. Metis cryptocurrency "METIS" is already online and trading on Binance. They have hinted at compensating users who engage in on-chain activity. Users that complete on-chain tasks on Layer 3 are likely to receive an airdrop in the future.
