Cross-chain NFTs ⛓️

Metaversal's post surveys the main approaches to moving NFTs between blockchains, noting that there is no single "right way" and that each method has its own tradeoffs. Equivalent bridging, such as moving an NFT from Ethereum to the Optimism L2, is described as conceptually simple but rarely seen in practice, with the Quix marketplace's former bridge now not working for the author. The article says burn-and-mint is more common, citing y00ts moving from Solana to Polygon and then to Ethereum. It also describes LayerZero's lock-and-mint ONFT approach, Holograph's hNFTs, Chainlink's CCIP, and Pirate Nation's mirroring system, which keeps assets on Ethereum while gameplay happens on Arbitrum Nova.
