Simple

All active web3 users have to manage names and addresses one way or another. We've seen it all. GSheets. Excel. Notion pages. Even Slack channels. And sometimes names are siloed in a wallet app. We don't like clunky. Addresso is anti-clunky.

Private

We don't know who you are. We don't need to, and we don't want to! At least in terms of associating you with your wallets and Addresso Books. Addresso runs on your devices not ours, syncing between your browsers and devices without cloud storage.

Collaborative

Sharing addresses should be fast and secure. And maintaining Addresso Books with your fellow DAO members, work colleagues, investment syndicate, and your family, should be a breeze. We're working on it.

Secure

You sign all changes to your Addresso Books. Batched for convenience. It's the only way to have peace of mind that the address you're about to use is the one you think it is.

Frequently Asked Questions

Check out our docs for more detailed product FAQs.

1. What problems does Addresso address?

Addresso is the answer to questions such as: How can I manage names and addresses for contacts, contracts, data sources, and AI agents? How can I keep track of my own wallets? What do these long meaningless strings actually mean to me in my wallets, exchanges, apps, browsers, and IDEs? How can I maintain an address book with others? How can I stop copy-pasting!?

2. How does it help AI agents?

Your AI agent acts on your behalf, but it can only do that properly when it understands your world, your subjectivity, your meaning, i.e. when it knows who's who and what's what. If it cannot relate words and phrases such as "Sis", "Bob", "the Yellow Collective", "the school", or "the team's multisig" to wallet and smart contract addresses, you might not think it too intelligent. There's no natural language corpus it can ingest to sort this out. There's only you, your AI, and Addresso. For more, see our Docs.

3. Is this a cloud service?

No, that's not how essential web3 tools are done. Addresso is yours ... a part of your everyday carry. Addresso runs across your devices under your control not someone else's at their whim. Your Addresso Books sync between your devices automagically without cloud storage. Not Your P2P Software Not Your Tech.

4. What is Addresso not?

Addresso is not a wallet. Addresso is not a place to store seed phrases or private keys or any other information that could give anyone control of your wallets. Addresso is not designed to store such information.

5. How does this relate to name services such as ENS?

Addresso and name services (NS) do different things. Addresso accommodates a future in which we all have many uncorrelatable wallets. Addresso has accepted ENS names since day 1, storing both the ENS name and the address it resolves to. Soon your Addresso will accept other name services too. It will flag whenever the NS name is expired, and also whenever the NS name resolves to an address different to the one(s) it resolved to before.

6. Is Addresso data private?

Yes. Addresso data resides on your devices, not ours. And it's securely encrypted. We maintain a service to enable your devices to keep your Addresso sync'd between themselves, but that service only passes on encrypted data that it cannot decrypt itself. Add to this that we can never know who you are, and we can't imagine how we could make this more private. You can find our Privacy Policy here.

7. Is Addresso onchain?

Maintaining an address book onchain would be mad! The Addresso App runs locally on your devices. Addresso is local-first with peer replication (CRDT), making it decentralized 💥 but not onchain of course. There may be optional aspects in the future that are delivered as a service, but these will always be subject to what's known as progressive decentralization. Perfection 🤓 is best pursued through progress.

8. How much does Addresso cost?

As everyone needs a web3 address book, as UX is critical to web3's growth, and as everyone should feel happy integrating Addresso into their lives, our core address book software will always be free.

9. What's the business model?

We have a few ideas as you'd expect. As you'd hope. None that risk free forever provision of the core address book software. And none that run counter to the founding ethos of the decentralized web or web3 more specifically. On the contrary, that's what drives us.

10. Where can I learn more about the Addresso tech?

Thanks for your curiosity! Addresso is being built just the way you'd hope it would be. Local-first. Decentralized. Device agnostic. Automated change recording and replication. Security and recovery by design. Built around homoiconic models. Click here to learn more.

11. What's the value proposition for wallet and app developers?

All wallet and app development teams can help their customers feel right at home by integrating their customers' Addresso Books quickly and easily. The SDKs are in development and we very much welcome your input. Get in touch.
