If you're building an NFT exchange for a web app for example, you will likely write a swap contract that swaps 2 NFTs. After you write the contract, you have to listen to events from your server, run a node, parse and format the events, stay in sync with the blockchain (even if your server goes down briefly)... and then integrate with your analytics provider. I've built systems like this for multiple companies and it's always a pain.

Blocktimize replaces all of this work with 5 minutes of setup. It also provides a mission control 'interface' for all of your active contracts and connections on both testnet and mainnet.
