Harpie: Frontrunning Malicious Transactions with Daniel Chong

I’m joined today by Harpie founder Daniel Chong. Harpie describes itself as an onchain firewall that protects NFTs from theft. In this episode we discuss how Harpie’s mempool monitoring and emergency vault contract works on a technical level. We also cover Harpie’s unique business model, and their growing enterprise service which grants organizations like OpenSea access to their malicious transaction data. We touch on their plans to build an RPC provider in the future that can detect dangerous transactions before they reach the mempool. At the end of the show, Daniel and I discuss Bitcoin Ordinals.

It was great getting to understand the approach Harpie is taking to wallet security. I think there’s a lot to learn from this episode. I hope you enjoy the show.
