How quill works

Each block does one small thing, and blocks snap together top to bottom like a recipe. There is no code underneath to edit: the blocks are the program

The shape says where a block can go. Pieces only fit where the rules allow, so a program that snaps together is a program that can run

A run starts when the event at the top of a rule happens. quill walks down the stack one block at a time; a wrapper checks its condition and runs its mouth or skips it; counters carry over to the next run. A run stops after 500 steps, or at the first failure, and the receipt says why. This one runs right here with pretend money

Every block belongs to one category; its colour and icon tell you which

Stocks a coin can trade: NVDA, TSLA, AAPL, SPY, MSFT, GOOGL (xStocks on Solana), at most three per coin, fixed at launch

A seal is a medallion struck from the rules alone, read like the rules themselves: a track per rule, a bead per block, a gauge per amount. Two coins with the same rules share a seal; change one number and it changes. Here a coin's rules grow one block at a time: watch the seal change with every block, and the name with it

Every coin gets its own vault wallet at launch, and the coin is created on pump.fun with that vault as its creator, so pump pays every creator fee to it. The vault's key is derived from quill's master seed and held only by the keeper, which signs only the moves the coin's published rules make

On the bonding curve, buys and sells go straight to pump.fun; after the coin graduates, and for stocks, they route through Jupiter

Nobody claims anything by hand. Every trade pays pump.fun's creator fee to the coin's vault; the keeper collects it about once a minute and fires the when creator fees arrive event, and the rules decide what the money does

• A rule spends a share of what the vault holds at that moment, never more. 0.01 SOL always stays for network fees
• Swaps accept at most 3% slippage
• One airdrop pays at most 50 holders
• Timers run at most every 10 minutes; an event fires at most five runs per rule per keeper pass
• A run stops after 500 steps; a wait lasts 30 seconds at most
• At most six rules and forty blocks per coin, three stocks, all fixed at launch

• 0.02 SOL sent to the coin's vault at launch, for its token accounts
• quill keeps none of a coin's creator fees
• The keeper pays the network fee of every rule transaction

Once the official coin is announced, each new coin hands 50% of its creator fees to the flywheel, and every launch pays a 0.02 SOL fee into it. The flywheel's wallet buys the official coin through Jupiter and burns everything it bought, every time it holds enough. The share is frozen into each coin when it launches and shown in the launch window; coins launched before the flywheel keep all of their fees

Every run leaves a receipt on the coin page: what fired it, each step with the values it used, and a link to every transaction it sent. The launch writes the rules' fingerprint to Solana in a memo from the creator's wallet; with a first buy the coin transaction is full, so a second transaction signed at the same time carries it

In the builder nothing real moves. After launch, money blocks spend only what the coin's vault holds, inside the limits shown before you sign. You can put SOL into a first buy at launch and own part of the coin from the first second

AI blocks ask Claude for one short line for the feed, or a yes or no about the coin's numbers. They never move money by themselves: a yes only lets the blocks inside run. Without AI on the server they are skipped, and the receipt says so

Web blocks read prices and call webhooks. A webhook gets a JSON summary of the run (the event, each step, the transactions), only at a public https address, checked after it is looked up, with no redirects and a five second limit

• Memecoins are extremely risky. A coin's price can go to zero. Nothing here is financial advice
• The vault key is held by quill's keeper. A bug or a compromised server could misuse it
• Tokenized stocks track a share's price; they are not the share. The issuer can pause, freeze or take them back. Not for people in the US, UK, Canada or Australia
• Rules are locked: a rule that turns out badly cannot be stopped
