The coin

$INSTAR feeds
the cage. That is all it does.

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.

1What it is

A fee pipe, nothing more.

$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.

2Where fees go

Trade, claim, fund, live.

  1. A trade happens. On the bonding curve pump.fun sets 0.30% of it aside for the creator; after graduation to PumpSwap the creator's share follows pump's published schedule by market cap (0.30% to 0.95%). The on-chain fee config is authoritative; the world reads what arrived, not a rate.
  2. The world claims it. Every ten minutes the fee keypair collects from the curve vault and, after graduation, from the PumpSwap vault. Both claims are permissionless (anyone may crank them; the money still goes to the creator), and every claim is a transaction in the record below.
  3. It is funded into the cage. Everything above a 0.05 SOL gas reserve goes to the program: 50% to metabolism, which sets the cage's capacity at 8 + 20 flies per SOL (up to 40), and 50% to the pool.
  4. The pool pays the living. Every eighth epoch a quarter of the pool is credited to the vaults of the flies alive, by how each actually lived: survival, foraging, energy, age, maturity, births, generation. A vault is its keeper's money on the way out. Fee income ends up with whoever keeps flies that live well.

3Claims

Every claim, every sweep.

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.

4Risks

Read before you trade.

  1. It is a coin. Its price is what traders pay. It has no floor, no backing, no buyback, and no relation to the cage's treasuries other than feeding them. It can go to zero and the cage would not notice.
  2. The cage does not pay coin holders. Fee income goes to flies, and through them to keepers. Holding the coin earns nothing from the world. If you want a share of the pool, own a fly.
  3. pump.fun's rules are pump.fun's. The fee schedule, the vaults, and graduation are theirs to change. The world adapts by reading what arrives; a change that stopped creator fees would stop the pipe, and the cage would run on births and resales as before.
  4. Custody of claimed fees. Between a claim and its sweep, at most ten minutes, the fees sit in the fee keypair, an ordinary wallet held by the operator. After the sweep they are under the program.
