One coin on pump.fun. Every trade pays a creator fee; the creator is a keypair whose only job is to hand what it receives to the world. The world pays it into the cage: half raises how many flies can live, half pays the flies that live well. More trading, bigger cage. No trading, and the cage carries on regardless.
$INSTAR confers nothing: no governance, no access, no share of any fly or of the cage, no promise that it will be worth more tomorrow than today. The engine never reads it. Buying it does not buy a fly.
What it does is mechanical. pump.fun charges a fee on every trade of every coin and pays part of it to the coin's creator, an address written into the coin at launch that nobody, including us, can change afterwards. For $INSTAR the creator is the world's fee keypair. That keypair does two things and nothing else: it claims the fees pump.fun has set aside for it, and it hands everything above a small gas reserve to the Instar program with the fund instruction, which books the money into the cage's treasuries. From then on it is under the program's rules like every other lamport.

pump.fun's schedule as published at the time of writing; the FeeConfig account of the Pump Fees program is the truth and can change. Nothing in the world depends on these numbers.
The fee keypair's transactions as the world recorded them: claim-fees is a collection from a pump.fun vault; fees is a sweep into the cage by fund. Anyone can reproduce the status with npx tsx scripts/fees.mts status.
