Rules

One rule, in plain English

Every creator fee buys Bitcoin and gold, weighted by risk. Burn $AURBIT any time and take your share of both. Everything below is enforced by the program at 9r8wkC… unless it says otherwise.

01Fees come in

pump.fun sends the coin's creator fees to the program's fee wallet, an address the program signs for. Each new fee is booked once: 20% to the dev, 80% to the holders. The holders' part waits as SOL until it is bought into Bitcoin or gold, and that waiting SOL is redeemable too.

Where pump.fun sends creator fees is a pump.fun setting held by the coin's creator, not something this program controls. The program only books what arrives.

02The buys

  • Anyone can trigger a buy; a keeper does it every minute. It swaps part of the waiting SOL into cbBTC or XAUt0 through Jupiter v6, the only swap program on the allow-list.
  • What lands in the treasury's vault must be at least the agreed minimum and at least the Pyth oracle value of the SOL spent, less 2%. Prices older than 120 seconds, or with a confidence band wider than 1%, are refused.
  • Only the leg below its target may be bought (either leg when both are within 2% of target), so every buy moves the split toward the target.

03The weights

The Bitcoin target starts at 50%, gold takes the rest. Once a month the weights are reset by inverse volatility: the keeper takes 360 daily closes of Bitcoin and gold, gives the calmer asset the bigger weight, publishes the inputs and writes their hash on chain with the new target. The program holds the target between 20% and 80% and accepts a change at most once every 25 days. The weights authority is the only key that can set it.

04The exit

Burn any amount of $AURBIT and receive your coins ÷ supply of the cbBTC vault, the XAUt0 vault and the waiting SOL, less 10%. The 10% stays in the treasury and raises the backing of everyone still holding. Redeem has no admin gate and keeps working after the admin key is given up. The burn is final.

05What the program does not allow

  • Taking cbBTC or XAUt0 out of the vaults any other way. The treasury signs for its vaults only inside redeem.
  • A coin that can be printed. The program refuses to name a coin whose mint can still create, freeze, tax or take tokens.
  • A different dev share or exit fee. 20% and 10% are constants in the program.

06What the keys can do

The admin key (CTNk…6kPP) can name the coin once, move the dev share to another wallet, name the weights authority (or nobody, which fixes the weights), and give itself up. It cannot touch the vaults, pause redeem or change the split of fees.

07The numbers on the site

The factsheet reads the treasury, both vaults, the fee wallet and the coin's mint straight from Solana, and prices them in USD with Jupiter's price API (Pyth as a fallback). The burn calculator uses the program's own formula, and every redeem is simulated against the chain before your wallet is asked to sign.
