In this PoolTogether Community Podcast episode, host Millie Yearley interviews Shane Mack, co‑founder of XMTP, to explore his personal crypto journey and the evolution of Web3 messaging. Shane recounts how a chance encounter on a Caltrain in 2011 led him to buy Bitcoin and hold it for a decade, shaping his perspective on long‑term conviction. He then describes the problem that motivated XMTP: wallets can send value but lack a native, secure way to send messages, creating a communication gap for DeFi, governance, and dApp‑to‑user interactions. A pivotal conversation with DeFi founder Robert Leshner highlighted the need for verified, wallet‑bound messaging, prompting XMTP’s design of a protocol where messages are signed by the sender’s private key and delivered off‑chain, while identities remain on‑chain via wallet addresses. The discussion moves to XMTP’s partnership with Coinbase, emphasizing a shared vision of making wallets the universal inbox and leveraging Coinbase’s ENS subdomain system (cb.id) for decentralized identity. They explore practical use cases such as On‑Chain Summer notifications, Converse’s broadcast feature, and the potential for brands to reach users without spam. Shane outlines XMTP’s consent‑based anti‑spam model, where protocol‑level opt‑in data replaces legacy trust‑based systems, and explains why messages stay off‑chain for scalability and privacy while identities stay on‑chain. The conversation concludes with a forward‑looking view of Web3 messaging becoming a global standard akin to SMTP, enabling direct actions (e.g., minting, voting) from within wallets, and inviting developers to build on the XMTP network.
