Payday should not depend on the employer being online.
I built Ooyaa, a USDC payroll on @arc
>Anyone can press Run payday and earn a 0.01 USDC tip.
>Each payee is paid once per period, in order, and the contract does the rest.
It already works that way. Within two days of going live, a wallet I don't control started running my demo payroll for the tip. It has run 72 of its 80 paydays. The other 7 were me testing.
- This only works because USDC is the gas token on Arc.
- A stranger pays the fee in USDC and gets the tip in USDC.
A proof page re-checks every cent live from the chain. Eight checks, stamped VERIFIED.
Arc Studio wrote and tested every contract and screen. Live on Arc mainnet. Not audited, so use small amounts.
Built completely using Arc Studio

Every AI picture now ships with a label inside it - a small signed note called Content Credentials that says where the picture came from.
Take one screenshot and the label is gone.
I tested this on one of our own pictures. The original carried its label. The screenshot didn't. A 600px re-share didn't. A WebP re-save didn't. To your eyes, all four look the same.
This matters more now than it did a month ago. Since 30 September,
-> California's AI Transparency Act covers every AI picture maker Californians can reach, of any size, and asks each one for a free public checker.
-> In the EU, AI picture tools that were already running have until 2 December to mark what they make.
So I built @moolamhq - a passport on @monad for every AI picture.
The passport doesn't live in the file. It lives on chain, with a fingerprint of how the picture looks: 64 yes or no answers about its light and dark patterns. The screenshot and the re-share changed 0 of the 64. A completely different picture changed 37.
What happens when a picture gets its passport
- The creator signs with their fingerprint or face, and Monad checks that signature inside the contract. No server decides it.
- @privy_io gives them an account from an email address. No seed phrase, and Moolam pays the network fee.
- @chainlink's network fetches the picture and measures it again on its own. Every new picture since 2 October was checked in 16 to 28 seconds.
- The holder can say how AI may use it: open, not for AI training, or ask me first. Any AI agent can read that before it uses the picture.
- @envio_indexer turns all of it into a live registry and a trust score for each AI agent.
What it doesn't do yet, said up front: a cropped copy doesn't match, a passport proves who registered first rather than who made the picture, and nobody outside has audited the contracts.
If you make AI pictures, give one a passport, then try to fool the checker with a screenshot.
If you run an AI picture app, DM me. The kit is free during early access and I'll set it up with you.

Mezo's FAQ says you can't use locked Bitcoin as collateral.
In August @MezoNetwork described the credit market Bitcoin needs: fixed repayment, lenders who pick their date, credit that can change hands.
So I built it for the Mezo Buildathon. It's called Doji.
Lock BTC as veBTC, borrow MUSD at a fixed rate until a Thursday you choose, and your Bitcoin keeps its lock, its votes and its rewards the whole time. Doji means "at the same time".
Lenders post their own rate for a date and get paid back on that date, or earlier as loans repay.
If a loan goes wrong, a protected auction pays lenders first and the borrower keeps the rest.
Live on Mezo testnet. Contracts verified, independently reviewed and tested against Mezo mainnet.
Try to break it: twelve real attacks, all refused.

Penny splits shared costs to the penny and plans the fewest payments to settle up. No accounts, exact to the last cent.
Every pull request on it tests itself. @Test_Sprite runs 24 browser tests on each PR's own preview, and main will not merge until that check is green.
To see it work, I planted a bug on purpose. PR 10: the odd cent went to the wrong person. The check went red, 18 of 21. 81 seconds later a GitHub job running Claude Code pushed a one-line fix. Green, 21 of 21, 4 minutes 44 seconds after the red. I read the fix and merged it myself.

The new Vana App is now live.
It sits behind the apps you use. When one of them asks for your data, you see exactly what it wants and decide. Say yes and the data moves with your permission, and the move is recorded.
See it work in OpenPet: connect an Oura Ring, get a pet that reads your sleep back to you.
Trying it this week earns XP.

Moolam is free, needs no account, has an API, and reads Content Credentials from any app😃
18/ What it doesn't do, said plainly:
-A passport proves who registered first, not who made the picture.
-No third party has audited the contracts.
-The private-picture check runs in Chainlink's simulator, one machine, not yet in a network enclave.
-Chainlink has checked 45 passports for look-alikes and labelled none so far.
19/ Moolam is Tamil for source, or origin. I want every AI picture to leave home with its passport.
