FIG. 2.1
The rules can't change
Every fee and limit, and every future change, is sealed before the first buy.
FIG. 2.2
Bots pay, holders win
Early bot buys pay a high fee that falls away. People who hold longer pay less.
FIG. 2.3
The money can't be pulled
What the bonding curve raises goes into a pool locked forever, and no one holds an owner key.
03Try it
Scrub through a launch.
Pick a template and drag through time. These are the same schedules the contract seals, so this is exactly what a token launched from them would charge.

04How it works
How a CAST launch works
- 1Pick a pair and a templateChoose what buyers pay with: ETH, USDG or a stock token. Then start from a ready-made rule set, or set each fee and limit yourself.
- 2Seal the rulesCheck the fairness grade as you edit, then launch. The rules lock in that block.
- 3Trade on the recordEvery buy and sell follows the sealed schedule, and anyone can check it on-chain.
05FAQ
Questions
The short answers. The full detail is in the docs.
What does “sealed” mean?
Every fee, limit and scheduled change is written into the token's contract when it launches. The contract has no function to edit them, and owner() returns the zero address, so neither the creator nor CAST can change anything later.
What can a token be paired with?
ETH, USDG (a dollar stablecoin) or a stock token. The creator picks one at launch and it can't change. Buyers pay with it, and fees, holder rewards and sells are paid in it. Prices show in dollars, so tokens with different pairs are easy to compare.
What is graduation?
Every token starts on a bonding curve, where the price rises as people buy. Once the curve has raised about $10,000 of the paired asset, the token graduates: everything it raised and the rest of the tokens go into its Uniswap pool at the curve's final price, locked forever. From then on it trades in the pool.
Who pays the Bot Tax?
Everyone who buys while it lasts, not only bots. It can be up to 50% and must fall to 0% within 24 hours of launch. The Fee Clock on each token page shows exactly what a buy costs right now.
How do holders earn?
Part of every fee is paid to holders in the token's paired asset, in proportion to their balance, and streamed out within 24 hours of the latest deposit. You collect it from your profile whenever you like.
Can the liquidity be pulled?
No. Before graduation, what the curve raises only leaves when people sell back to it. At graduation it all goes into one pool position the Fee Hook refuses to let anyone remove, including the creator and CAST. The paired asset only leaves the pool when people sell.
What is the fairness grade?
A score from A to F that the Rulebook contract computes from the sealed rules: how high fees stay, how fast they ease, how much can reach the creator, and whether the creator's tokens are locked.
Is this real money?
Yes. CAST runs on Robinhood Chain mainnet, so tokens, ETH, USDG and stock tokens here have real value and every trade is final.
