Stay Ahead of NFT Activity

Optimism has become just the latest blockchain to be added to Alchemy's NFT Activity Webhook. This means users can now track all NFT activity on Optimism.

Users are now able to enjoy notifications sent directly to them, whenever there's an Optimism NFT transfer that they care about.

The NFT Activity webhook allows you to track ERC721 and ERC1155 token contracts for Ethereum, Arbitrum, Optimism and Polygon NFTs. This provides your app with real-time state changes when an NFT is transferred between addresses.
