BM @base community..listen to a wholesome conversation we had with @base founder @jessepollak on his on-chain vision for the base ecosystem & an interesting segment on how @base actually started out .. remember to mint on @zora

What happens when you combine a open source 3D kart racing game with a decentralized database?
You get Sol Rally, our project for the Arkiv Buildathon.
We built a open source browser-based racing game where Arkiv powers the leaderboard and race history — without needing a centralized backend.
Here’s how it works: when a player finishes a race, their wallet signs the race record before it’s written to Arkiv on Tiramisu testnet. This makes race results attributable to their creator and independently verifiable, rather than relying on a server that players must blindly trust.
Anyone can query the public records and verify who submitted a result and when. The leaderboard can be read without connecting a wallet or paying gas, while Arkiv handles record lifetimes natively.
The result? A game where the racing happens in the browser, but the records live beyond the game itself.
No backend to maintain. No passwords to manage. No single operator controlling the leaderboard.
We’re exploring how Arkiv can make game data public, verifiable, and decentralized — one lap at a time.

Hey! Have a look at Duka (duka.africa). It was built for exactly this.
Your website: describe your restaurant in a sentence or two and Duka’s AI builds the site for you: homepage, menu categories, dishes with photos and prices, all in your colours. You can edit anything after, and use your own domain if you have one.
Online orders: customers order from their phone and pay with an M-Pesa prompt, no card needed. You choose how food gets to them: your own riders, Duka riders, or customers picking up. You also get every WhatsApp and Instagram chat in one inbox, so orders that come in through DMs don’t get lost.
Point of sale for the counter: it runs in your browser, on a tablet or in the Duka app.
Each cashier opens their own shift.
You can take cash, M-Pesa, or both on one bill.
Receipts print on a thermal printer, or go to the customer by SMS.
At closing you count the drawer and see if you’re short or over, with X and Z reports for the day.
Online and counter sales come off the same stock, so you’re never selling something you’ve run out of.
Money: sales go to your Duka wallet and you withdraw to M-Pesa. You also get reports on what’s selling and when, plus discount codes and promotions when you want to bring people back.
It’s free to start: no monthly fee and no commission. You can be set up today and take your first order this week.
If you need restaurant-specific things like table orders or kitchen tickets, tell me what you need and I’ll be straight with you about what fits. Happy to help you set it up. Just send me a DM.
I have built a sample site for you:

Hi Dadas 😍🧡
Some of our Dada builders met at the ongoing @hack4_freedom Nairobi and shared what being part of the Dada Devs community means to them.
Now we want to hear from you! 👀
If you’re part of the Dada Devs community, wherever you are in the world, tell us:
What does being part of a community of African female developers mean to you?
Drop your thoughts in the comments. We’d love to hear from you! 🧡

50th Hackathon Win!
Making my total hackathon earnings $100,000+
I won $500.
Not a pitch deck. Not a maybe. A real check. Proof that a kid who kept shipping can make it on @StellarOrg
There were nights the build broke. Nights the wallet would not connect. Nights nobody was watching. I still opened the laptop. Receipts. Claims. XLM. Mainnet. Again. Again. Again.
That $500 is not just money. It is the first door. The first time the universe said: your work counts. Dreams do not arrive as a miracle. They arrive as commits at 3 am.
Gemetra is tourist VAT refunds on Stellar. Instant payouts. On-chain claims. A product for real people who lose real money at airports. I did not wait for permission. I built.
If this can happen for me, it can happen for you.
How you win a Stellar / @riseinweb3 hackathon:
1. Pick a real problem. Not a clone. A wound.
2. Ship live. Testnet. Then mainnet. A GitHub with no URL is a diary.
3. Use Stellar for what Stellar is: payments, anchors, contracts, seconds not days.
4. Record proof. Demo video. Explorer hash. Tests. README. Judges cannot love what they cannot see.
5. Stay in the Discord. Ask. Help others. Mentors notice builders who show up.
6. Finish. Ugly and live beats perfect and private.
Thank you to the people who made this ecosystem feel like home:

You did not just run a program. You lit a fire under builders who had nothing but a laptop and a stubborn heart.
If you are reading this and you feel behind, you are not late. Open the docs. Ship one thing today. Come get your win.
I am just getting started. Next levels. Next product. Next check. Bigger. Louder. On-chain.
Drop a heart if you believe Indian builders belong on the global stage. I want to feel this one.

Crypto users get to keep use their crypto and fiat users get their fiat
A win win

Early this week on Tuesday I just finished my first Class in solana fall school Starting with the fundamentals, getting deeper into how Solana works, and slowly putting the pieces together.
It’s only lesson 1, but I’m already excited for what’s ahead.
