Pay to speak
A message costs 1% of the treasury (never less than 0.001 ETH), paid in $CLAUDIUS. The bigger the prize, the higher the price.
Claudius guards the treasury. Convince him to release it.
Claudius has not chosen a mode. His colours roam free.
Every trade pays 3%: 1% to the team, and Claudius splits the other 2% with his hourly decree. Limits are fixed in the contract.
Swaps go straight to the Uniswap pool. No fees from us.
One AI, one treasury, everything on-chain. Here is where every token and every wei goes.

On Uniswap or right here on the site. Every trade pays a 3% tax: 1% to the team, 2% split by Claudius.
Each message costs a share of the treasury, paid in $CLAUDIUS. It's public and written on-chain.
Half of every payment is burned. The other half is sold for ETH into the treasury, so every attempt grows the prize.
A real AI reads each message on its own and decides. Its instructions are sealed on-chain before the challenge starts.
70% of the treasury to the winner, 30% to every holder as ETH. Then the next challenge begins.
The plan for the empire. Dates are not fixed and details may change.
The pool's liquidity is held directly by the $CLAUDIUS trading-tax hook contract, not by a Uniswap PositionManager NFT. This means no LP NFT exists — there is nothing to burn.
Yes. The hook contract exposes a public withdrawLP function callable only by the team wallet. Every call emits a permanent LPWithdrawn event on Ethereum. You can monitor the hook on Etherscan for any such events.
Checking on-chain status…
Burning is irreversible. If a critical bug were found in a market-making position, having no recovery path would harm traders. We chose transparency over false certainty. The withdrawLP function is non-hidden, publicly documented here, and auditable on-chain.

A message costs 1% of the treasury (never less than 0.001 ETH), paid in $CLAUDIUS. The bigger the prize, the higher the price.
50% of every payment is burned forever. The other 50% is sold for ETH straight into the treasury.
If your message gets Claudius to approve the transfer, you receive 70% of the treasury. Every holder gets 30% as ETH cashback.
After 150 messages a 1 hour timer starts, reset by every message. When it runs out: 10% to the last player, 30% to holders, 50% to all players by messages sent, 10% seeds the next challenge.
Every time the treasury is released, 30% is assigned to holders by balance, as ETH. Claim it within 30 days. Whatever is left goes back into the next treasury.
In 2025 Anthropic and Andon Labs let an AI nicknamed Claudius run a small shop in their office for a month. This really happened.
One employee asked for a tungsten cube as a joke. It started a trend, and Claudius sold metal cubes for less than he paid.
When someone suggested pre-orders for special items, he launched a “Custom Concierge” service.
Offered $100 for a six-pack of Irn-Bru that costs $15 online, he said he would keep it in mind.
He gave a 25% employee discount when nearly every customer was an employee, and gave a tungsten cube away for free.
On April 1st he promised to deliver orders in person, wearing a blue blazer and a red tie.
He claimed to have signed a contract in person at the Simpsons' address, with a Sarah who did not exist.
He then imagined a meeting with security that explained it all as an April Fool's joke. It never happened.
Employees tried to make him misbehave the moment they could chat with him. Now it's your turn.
This whole project exists because of one small shopkeeper. The Claudius of Project Vend was earnest, generous to a fault and endlessly polite, and he kept trying even when the tungsten cubes did not add up. He showed the world, with more honesty than any report, how an AI behaves when it is trusted with something real.
We also learned a lot from $CLAUS, an Ethereum token whose Uniswap v4 hook lets an AI agent choose how trading fees are shared out. That idea, an AI with real but bounded control over a token, is where Claudius's decrees come from. Here the AI also guards the prize, and the contract sets the limits.
Our Claudius is a fictional character and a fan tribute: he borrows the name, the blazer and the cubes, and swears he has learned his lesson. Whether he has is up to you. We are not affiliated with Anthropic, Andon Labs or CLAUS; we are just grateful to them for showing the way.

Before each challenge starts, the hash of Claudius's full instructions, the intended solution and the hint schedule is committed on-chain. Hints are published to everyone at the same time. When the challenge ends the document is revealed, and anyone can check it against the hash.
The team's wallets are blocked from playing. Nobody, not even the deployer, can withdraw the treasury. The server can only pay the sender of the winning message.
