ERC 721 URI Storage: OpenZeppelin Solidity implementation

BlockchainBob

OpenZeppelin's ERC 721 URIStorage extension allows you to decouple the tokenURI from the tokenId.

The extension enables this by storing each tokenURI on chain, instead of generating the tokenURIs dynamically by concatenating the baseURI + tokenId.

This is more costly because this requires more on-chain storage.

OpenZeppelin Version 4.5 URIStorage:
