Key ideas
The six ideas behind Fuelgauge, each in a few sentences.
#Creator fees
Every trade of a pump.fun coin pays a small creator fee. Normally it collects in a vault controlled by the coin's creator, who can spend it on anything, or nothing. Holders cannot see what it was used for.
#The split: 95% vault, 5% burn
pump.fun lets a creator share those fees between up to ten wallets. A coin on Fuelgauge shares them between exactly two:
- 95% to the coin's budget vault, a Squads multisig made for this coin.
- 5% to the $GAUGE burn, which buys $GAUGE and burns it.
When the split is set, pump.fun revokes the right to change it. Nobody, the creator included, can point those fees anywhere else afterwards.
#The budget vault
The vault can only pay budget lines. A line is a payee wallet, an amount, and a period (per day, week or month), written on chain as a Squads spending limit: it can pay that one wallet, up to that amount, each period, and nothing else.
Most vaults are locked: after setup, nobody can execute anything on them, so the budget lines are the only way SOL can leave. See Locked and editable vaults.
#Receipts
Every SOL movement in or out of the vault is a public transaction. Fuelgauge reads them back and shows them as receipts on the coin's page, each with its line and the creator's note.
#The gauge
The gauge reads days funded: how long the vault's balance pays the whole budget. A full gauge is 60 days. Next to it, fee coverage compares the last seven days of fees to what the budget spends. See The gauge, exactly.
#The sunset
If no budget line has been paid for the coin's idle period (60 days unless the creator chose otherwise), the vault's SOL starts buying the coin back and burning it, up to a weekly cap. Fees from an abandoned project go back to holders instead of sitting idle. See The sunset.
