Your wishes, kept.
We built Deed - an AI trustee for everyone.
Write how your money should be used, sign it with your wallet, and the trustee pays only what your wishes allow, in USDC on @base
It decides every request three times on SERV. Code checks every limit. Tricks get stopped, and a person you trust can step in
Live on Base mainnet and testnet.

Korea's new anti-scalping law says every ticket buyer has to be verified.
Most platforms took that as "collect more IDs, scan more faces." I didn't love that, so I spent the time building something different.
Meet FaceValue (정가), built on @MidnightNtwrk 🎟️
Here's the demo 👇
The idea is simple:
• You get verified once. The chain only keeps a scrambled code, not you
• One entry per person in a fair draw, so bots and extra accounts are useless
• You pay the printed price. Try paying more and the contract just says no
• There's no transfer button at all. Can't go? You get a full refund and the seat goes back at face value
• At the door you show a code that changes every 30 seconds. No name, no ID, no face scan
---
The fun part is the privacy.
10 Compact circuits prove you're verified, that you only entered once, that the draw was fair and that you paid exactly face value, all with zero-knowledge proofs.
So anyone can check the rules were followed, but nobody can see who's who.

Would love to hear what you think 🙏
Introducing Deed: an AI trustee for everyone. My entry for the @openservai SERV Hackathon
Families send money home with rules attached: school fees, not phones. From another country, you can't say no in time
A real trust fixes that, but it costs thousands to set up, so almost nobody has one.
Deed does it in five minutes
You write your wishes in plain words, and a bounded reasoning graph on SERV becomes the trustee:
-> the wishes are checked for gaps before any money goes in, every request is screened for hidden instructions, the trustee decides three times and the strictest answer stands, and a deterministic check confirms the clause it quotes is really in the wishes.
A decision moves no money by itself.
Fixed rules in code check every amount against what was asked, the per-payment cap, each person's yearly limit and what the trust holds.
They can only lower an amount or turn a yes into a no
Money only ever goes to the wallets the settlor named and signed for, and the server verifies that signature before the trust exists
If the runs disagree, or the quote isn't in the wishes, the payment waits for a human protector.
A request that tries to override the wishes is stopped, and the protector gets an email automatically. One tap pauses every payout
Funding is one passkey tap with Pay with Base. Payouts are $USDC from the trust's own Coinbase AgentKit wallet on Base.
Each person gets a private link, and a trust is invisible without one
Live on @base mainnet with real USDC, and on Base Sepolia for testing
Balances and history are read live from Base, and every payout is a transaction you can open.

Mike is a plumber. When he's under a sink, he can't pick up, and the caller just rings the next plumber
Solo tradespeople lose jobs this way every day.
So we built HangON, a voice front desk that answers when you can't
we recorded a real call on our live platform.
A caller reports a leaking sink, HangON tells her to shut the valve, then asks when she'd like someone out.
She says, "Tuesday afternoon? Actually, no. Make it Wednesday at 2." Most bots would cut in at "Actually, no." HangON waits and keeps her final answer
Wednesday at 2 is taken on Mike's real calendar, so it offers open slots. She picks Friday at 9:30.
It reads the details back, books only after she confirms, and emails her a confirmation from our domain.
Mike gets a brief: the problem, the caller's mood, and what to bring
@AssemblyAI's Voice Agent API runs the whole call over one connection, interruptions included, with "balanced" turn detection so people can pause mid-thought.
Tools handle the calendar, booking and email. The LLM Gateway extracts the job details and writes Mike's brief, leaving blank anything the caller didn't say
Our rule: if it doesn't know, it doesn't pretend. No invented names, prices, or fake "sent" messages

Never miss a job while your hands are full
tokenized stocks are already trading on @solana.
Backed has 32 of them live as xStocks: NVIDIA, Apple, Tesla, the S&P 500 and more
what was missing was a proper place to use them
so we built OpenStock: a desk to trade them, and a way to launch tokens priced in them instead of solana:So11111111111111111111111111111111111111112
live here -> https://t.co/OFak1XVTWl
also, here's a walk through the whole thing 👇
@xynetech@Datweb3guy it halllucinates a lot, too lazy with execution (going out of what it is instructed to do), and many more..
they have lazy reserachers at google
tokenized Stocks on @solana just hit over $2.5B in spot DEX volume over the past 30 days, a 153.6% in increase
and over 107 reference stocks printed volume
that is no longer a thin market around one or two tickers
Secondary trading is already flowing on @Raydium
Credit is already live on @kamino
and @JupiterExchange Lend, where you can deposit SPYx or NVDAx and borrow USDC against it
@krakenfx vaults run the same loop for SPYx, QQQx, and NVDAx
what more do you expect to get built on top of these stocks??
we on the other side (@joinopenstock) is building on the stock narrative as well
soon you will be able to launch community tokens against these equities, pair them into live pools, and use the same stocks for more than a straight buy and sell
volume proved the assets can trade
the next market is everything that sits on top of them
more details soon >>
here is what we did for the @bankrbot hackathon, ser
as Base will always say... stocks are not static
they pay dividends and they split, and that is why Coinbase tokenized stocks on @base are B20
so we built, @TalonOnBase (submitted for the builder quest hackathon and Bankrbot hackathon) which lets you hold those two things separately
a user deposit official AAPLc, it goes into:
> Clip - which keeps the B20 growth.
> Talon - keeps the price.
same amount of both returns the stock. 1 to 1
for the @bankrbot hackathon we put Bankr in the product as Sentinel
Bankr is the copilot that runs the vault
in the app you pick a strategy or you type it.
> Earnings Shield: Bankr splits the stock before earnings, hedges the price side, leaves Clip with you.
> Accretion Yield: Bankr shows the multiplier with price taken out.
> 1 to 1 / Audit Invariant: Bankr reads the vault on Base and checks every Clip and Talon is still fully backed.
then Bankr prepares the Base transaction, and the user signs in their wallet
here is our live product: https://t.co/dcIl4nlJ9g
https://t.co/6kS8MXhcGF
the market is closed but @solana stock market is open
and you can trade stocks, launch tokens/any stock of your choice, build with stocks, and dream bigger about what stocks can do
24/7 - everyday
