1. Quix NFT Marketplace
Quix is the largest and most popular NFT Marketplace on the Optimism layer 2 network. It trades the most 24-hour volume at $1,000,000 USD in NFTs through popular collections like OptiPunks, Motorheadz, Bored Town and more. This marketplace also allows you to sell your UniV3 liquidity positions.

2. OpenSea - Optimism
OpenSea is the world's largest NFT marketplace with billions of dollars traded since their inception in late 2020. OpenSea is deployed on the Optimism network, as well as Ethereum, Solana and other platforms - making it a multi-chain NFT Marketplace. It is a good alternative to Quix, but isn't as popular for Optimism artists, creators and collectors.

3. Backed NFT Lending
Backed is an NFT lending platform that allows you to leverage your digital art and collectables as collateral for cash loans. The loans are denominated in USDC and the interest rates start at 4% APR. Backed is deployed on the Optimism network, as well as the Ethereum mainnet.

Why are NFTs popular on Optimism?
One of the benefits of using a marketplace that's built on Optimism is that you can trade NFTs much faster and cheaper than you can on the Ethereum mainnet. Plus, with gas fees being so high at the moment, it's worth considering using a Layer 2 platform like this to buy and sell your NFTs.
