About

Launched in 2017, OpenSea is the largest general NFT marketplace across Ethereum, Solana, Polygon and more, covering collectibles, art and domains. Still the most liquid broad NFT venue despite newer rivals.

Blue-chip liquidity is fine; long-tail NFT liquidity is poor — check historical sales depth before buying. Listed prices and actual fills can diverge.
