Arbitrum Odyssey is an 8-week event to encourage users to explore the Arbitrum chain. Arbitrum is a Layer 2 scaling solution built on top of the Ethereum blockchain that significantly reduces transaction fees compared to the Ethereum mainnet while allowing for a higher transaction throughput. Each week of the Arbitrum Odyssey focuses on two different protocols on the network and offers different tasks for users to partake in that utilize those protocols. Once a user completes a task, they are able to claim an Arbitrum Odyssey NFT signifying their completion. There are a total of 15 participation NFTs that are claimable over the 8-week Odyssey. Any user that holds at least 12 of the 15 NFTs is able to claim an exclusive Arbitrum NFT at the end of the event.
