Every trade feeds the fund
Buy and sell on a bonding curve inside the coin's own contract. A slice of every trade drops into the Ejecto Fund.
Rule: 1.5% of buys and 2% of sells on the standard preset
Everymemecoindies.
Ours come with an ejection seat. When the coin dies, anyone pulls the handle and every holder claims a fair share. No exit race. No admin keys.
The problem
Source: CoinGecko study of Pump.fun launches (2026): about two thirds stop trading within 24 hours. When a coin dies, the early sellers get out and the loyal holders are left with a token nobody buys.

Hype. Buys pour in. Every trade drops a slice into the Ejecto Fund.
How it works
Three rules, all inside the contract. Locked at launch, nobody can change them later.
[02]
A dead coin arms the seat
Once a coin is 14 days old, it is dead when its 14-day buys fall below 5% of their peak, and at least below 1 NEAR.
Rule: no oracle, no admin. The contract does the counting
[03]
Everyone gets a seat
Anyone presses EJECT and trading stops forever. Holders claim the reserve pro-rata, plus a fund share by net capital times time held.
Rule: late whales lose. Loyalty is what the fund pays for
The math
500 simulated coins, 400 traders each, 60 days.
Same traders, same luck. Only the ending changes.

How a dead coin ends
Race
Sell into a falling curve. The last ones out get almost nothing.
Eject
Median day 28. Everyone left on board claims the reserve and the fund.
Note: Ejecto removes the exit race and the total wipeouts. It does not make everyone profitable: early buyers got more tokens per NEAR, so late buyers can still lose part of their money. Figures come from the agent-based model in sim/ejecto-sim.mjs.
Safeguards
The track rules: the mechanic lives in the contract, no admin key.
Six ways we keep that promise.

Parameters written once
Curve, fee preset and day length are set in the init call at launch. They cannot change afterwards.

-31%
A late whale's result, at best
The fund is split by net capital times time held. In the model, buying big right before EJECT loses 30.8% to 48.5%.
[05]Pull claims

Withdraw your own share
After EJECT each holder claims for themselves. State is updated before any transfer, and repeat claims are safe.

Code hash on chain
Every coin runs the same code. Its sha256 is public in the fleet.ejecto.testnet config.
