Coins with off-chain hooks

What's a hook?

One sentence. When WIF market cap is above $250M, $HOOK pumps its fee to 3%. The first half is the trigger: a number from a link, and a line it can cross. The second half is what the coin does while the trigger is true. You can also hook a coin to Claude: give it a page and a yes/no question, and the hook is on while Claude says yes.

Hooks where the fee follows the number

Some hooks don't switch on and off. The fee follows the number instead. You pick two points: at 0°C the fee is 0%, at 30°C it's 3%. In between, the fee moves in a straight line, so at 15°C it's 1.5%. Under 0°C it stays at 0%; over 30°C it stays at 3%.

It can run the other way too: 2% at 500K players, down to 0% at 1.5M. Every check moves the fee to the new number.

• It only sets the fee. It never pauses buying or selling.
• It needs a number from a link. Claude's yes/no can't be followed.
• If the hook goes quiet, the fee goes back to the fee at the low end (0% in the example) until it's back.
• The dev can change the two points and their fees later. The kind of hook is set at launch.

Who checks it?

A blockchain can't read websites, so a bot does (we call it the reporter). It checks your link on your schedule and writes to Solana only when the answer changes, plus a heartbeat now and then to show it's alive. Anemone runs one for every coin, or you can name your own reporter and run the open-source one yourself.

Every flip is onchain with the value the reporter saw and a fingerprint of the response it read, so anyone can check the same link and call it out.

Market cap, bonding curve, fees

• Every coin has 1,000,000,000 supply. About 79% sells on the bonding curve; the rest stays in the curve's vault for later liquidity.
• Coins start at about 28 SOL market cap. Every buy moves the price up the curve, every sell moves it down. The bonding % is how much of the curve has been bought.
• Normal fee is 1% of each trade, in SOL. The dev gets 80% of every fee and can claim it any time; the protocol keeps 20%.
• The curve is the market for now. Graduating to a DEX pool when the curve fills up is the next thing we're building.

What a hook can't do

• It can't touch anyone's coins or SOL. Mint and freeze are revoked at launch.
• It can only move the fee between the two numbers the dev picked (10% max), or pause one direction of trading.
• It can flip at most once per check interval, whatever the reporter does.
• If the reporter goes quiet while the hook is on, the coin goes back to its normal fee and open trading on its own, and anyone can switch the hook off.
