The Addresso logo and a rocket icon.

We’ve needed purpose-designed address books for every technological wave, from the postage stamp to cell phone numbers. Web3 is no exception.

Yet any old address book simply won't cut it when it comes to web3. As a valuable part of the decentralized web, there are certain things you just have to get right.

Addresso is the first purpose-built web3 address book that isn't welded to a specific wallet application. We've designed it so we can say with just a hint of pride:

  • Addresso is yours
  • You have sole control
  • It runs solely on your devices
  • The data lives only on your devices
  • It’s always encrypted with your passphrase
  • You sign additions and changes for complete security.

For the more technically fluent, Addresso is local-first, peer replicating, git-like, self-custodial, and — of course — secure. And it's going to serve you beautifully when it comes to getting your personal AI up to speed.

Our core address book software will always be free. And that includes everything we've built so far, and more to come.

Check out https://addresso.com for further information. And please don't be shy letting us know what you think — we crave feedback as you might just imagine. 🙏🏼

P.S. We're currently scoping the design of collaborative Addresso Books. If that sounds like something you and your colleagues / fellow DAO members / friends / family have been waiting for, please get in touch now. The more we understand your needs, the more likely we'll make you smile. 😁
