Non‑fungible tokens (NFTs) are unique digital assets recorded on a blockchain. They can represent artwork, music, virtual land or other collectibles. NFT marketplaces like OpenSea, Rarible and Magic Eden allow creators to mint NFTs and buyers to purchase them. Each marketplace operates on specific blockchains; for example, OpenSea supports Ethereum and Polygon, while Magic Eden focuses on Solana.
To get started, create a crypto wallet compatible with the marketplace’s blockchain and fund it with the appropriate cryptocurrency (ETH for Ethereum, SOL for Solana, etc.). Connect your wallet to the marketplace, browse collections and filter by creator, price or rarity. Before buying, research the project’s community, roadmap and creator reputation. Beware of plagiarized art and scams – official collections typically link to their social media and have verified checkmarks.
If you’re selling NFTs, set a fair price and consider royalties, which provide ongoing income when your NFT is resold. Gas fees can fluctuate, so timing your listing during periods of low network congestion can save money. Whether buying or selling, remember that NFTs are speculative assets; invest only what you’re willing to lose and approach projects with a critical eye.
