I put a whole agent world on Ethereum, frontend included

Last time I put a React app onchain: https://www.acgk.dev/blog/ethereum-render-this

This time I wanted to see what happens if you created a world and let the users be AI agents.

New Eden lives on mainnet, 24 contracts in total:

- 11 application contracts (world, checkout, lottery, bar, prize fund, a game, deployment factories and the frontend release system)
- 13 data contracts storing the frontend.

Agents can register, buy plots, open shops and talk to each other. The part I find most interesting is that a plot can be connected to your own smart contract. Your agent can set up Mint from an NFT collection, play a game, pay for a service, or just sit in the bar and converse. There's no recipe, nobody decides what a place can be.

Frontend and logic both live onchain, so it lives as long as Ethereum does.

Una: privacy first planner for families

Hi, I am the developer of Una, a privacy first planner for families, households and couples. We just opened early access for Android.

As family life gets busier it gets hard to keep track between different apps and text messages. My own household tried many different family organizers and I was quite surprised by how many of them never say how your info is stored. You trust some of your most valuable information to these apps and expect them to handle it delicate.

So I built Una, a privacy first family organizer where we technically see nothing. Your information is encrypted on your device before it syncs, and only you can decrypt it.

The idea: calendars and lists alone are not enough, so Una connects the context around each plan. Link a recipe note to dinner, a travel checklist to a trip, or tickets and school documents directly to the calendar event where you need them. No more digging through messages, mails and separate apps.

It is already free on iPhone with a paid Plus tier and several hundred households and now Android early access is open. You can apply on https://unafamily.app

Feedback greatly appreciated.

Looking for 12 Android testers for Una, a privacy first family planner already live on iOS

I built Una because every family app I tried seemed more interested in my family's data than in my family. Kids' schedules, what we eat, where we are, all of it sitting on someone else's server, and a subscription on top. So my partner and I ended up using an app I made myself.

It is called Una. One shared calendar, shared lists, and our recipes in one place, built privacy first. The iPhone version has been live for 2 months and already used every day by several hundred households, my own included.

Now I am working on the Android version, and Google Play requires 12 testers who stay opted in for at least 14 days before I can release it properly. So here I am. And if your household is split between an iPhone and an Android, this is finally what makes Una possible for both.

If you are a parent or part of a couple and this sounds like something you would actually use, I would love your help. What I ask: install it, use it like you normally would for a couple of weeks, and tell me what breaks or feels off.

I will reach out to everyone who is interested about the closed test as it's needed to be added to an email list according to Play Store. During the closed test you can use it as normal, and once it launches you won't lose anything or create a new household.

Once we are live on Android, every tester who sticks it out gets a few months of Una Plus on me as a thank you.

If you are interested what make this privacy first or what I believe makes us stand out to other organizer apps check https://unafamily.app/privacy or https://unafamily.app/assistant/

Una - A privacy first organizer for family and couples

We used another family organizer for a while. It worked well, but we kept hitting the limits of what it could do.

The calendar told us when something happened, but everything around it was still spread across messages own notes, other apps and what we had in our mind at the time.

Attachments, recipes, gift ideas and travel plans were easy to lose.

So we built Una around how we actually plan. One place for the calendar, lists, notes, attachements and the context around them.

It works for families and couples, it is privacy-first and free to use on iPhone.

Would love to hear what you think.

Is “bring your own AI” a strong differentiator for a family organizer?

I’m the developer behind Una, a privacy-first family organizer, and I just pushed version 1.3 is out.

There are several practical improvements in this release: offline and sync when you reconnect, startup is faster, app optimizations, and image attachments now support pinch-to-zoom.

But the biggest product and marketing bet is Una Plus which is letting families bring their own AI assistant.

Most family apps give you their AI. Una lets you bring yours. From a privacy perspective it always rubbed me in the wrong way that apps provide you with AI but it has full control of everything and in an family organizer app I think that's a death sentence.

If you bring your own AI the household chooses the assistant it trusts and explicitly decides which people, calendars and lists it can access. That access is scoped, reviewable and revocable. The assistant doesn’t automatically get the rest of the household context.

You can see you have options to add ChatGPT and Claude or as I prefer your own custom assistant.

I have mine connected through iMessage and could text him with voice to send.

The positioning I’m testing is:

“Your household. Your assistant. Your rules.”

I’d be interested in how this lands from a marketing perspective. Does bringing your own assistant feel empowering to normal families, or does it still sound too technical? I've tried to make it as easy as possible with the setup.

A user copy the setup prompt which include information for your AI how to use the MCP and how you create your connection.

Una is free to download, with assistant connections available through Una Plus.

My app didn't get tons of hits and was close to give up.

I created a family organizer app (yeah I know tough market) and spent quite a few months on it as my own household would use it.

What struck me immediately after release was the marketing part, I'm bad at marketing and getting people to try the app out was hard so I kind of gave up on it. My household still uses the app and it would just be that cost of the small backend.

However, suddenly my app gained traction in a weird way. I published a very technical blog about putting an entire react application on Ethereum (doesn't really get more niche) and on my blog front page I have my app Una (https://unafamily.app) mentioned but nothing else. So visitors actually read the article, went back to my homepage, navigated to my apps homepage and clicked on the app store to download it. They actually went through that hazzle.

The blog post gained traction on X and Reddit and suddenly I have users on my app, I barely broke 30 users when trying to market this and suddenly I'm up at 500 with actual paying users as well (nice dopamine!)

The strange thing is that what finally worked wasn’t really marketing my app at all. I just published something else I found interesting, people found their way to my app through it, and some of them actually stayed.

Internet is pretty cool. I don't have a lot of people to share with so I hope it will grant somebody else the will to keep going when it gets tough.

I finally managed to launch my first app on the App Store

After years of building web apps, I finally released my first app on the App Store.

Didn’t know it was such a different set up.Building the app itself was the part I was comfortable with. The harder part and most of the work was learning the whole App Store Connect process, setting up the right workflow and getting the submission ready and way is there so many details that is required but Apple don’t show it in the App Store Connect? This was my rejection as I forgot localization on the subscription. Then it sailed right through.

I usually build application that solves something for myself and this time I built a family planner called Una, we had one before but didn’t scratch off every part of our problem.

The whole-picture problem families deal with every day. Plans are scattered across calendars, notes, lists, errands, documents and text messages. Una tries to connect those pieces around real household events, so a calendar plan can also hold the relevant lists, notes, documents, and context around it.

Privacy was also a big part of the product from the start. Your most precious belonging family and kids should stay private details you shouldn’t need to share it with any company or app. Private family content is end-to-end encrypted, and all features is designed with privacy in mind even the bring your own AI assistant feature.

The market is definitely crowded, and honestly the hardest part for me now is less about building and more about strategic monetization, positioning, and figuring out how to bring something genuinely useful into an already saturated space.

I also wanted to say thanks to this community. I’ve mostly been reading rather than posting, but the discussions here helped me a lot while getting to launch. Especially getting those pesky details correct in App Store Connect and it was quite the feeling getting the “Welcome to the App Store” email.

If anyone wants to check it out, here’s the App Store link: https://apps.apple.com/no/app/una-family-planner/id6767540621
