email is better than all the other chat apps

ethereum is email. global, canonical & you can build on it without asking.

notice how per-company, per-country chat apps (and their various proprietary app ecosystems) come and go, but email is forever. it's been around 60 years and will be around another 600.

Daimo Pay. Build once, distribute everywhere

Exactly! Ethereum provides a similar foundational layer for decentralized applications, offering longevity and interoperability that proprietary systems cannot match.
