How it works
A volcano coin is a normal Stonks coin with one public mechanism on top. Here are the exact rules. Nothing else moves it.
The pressure
Each coin has a magma chamber. Its pressure is counted in % of the coin's supply.
- A buy adds its full size. A buy of 0.40 % of supply adds 0.40 %.
- A sell removes half of its size. A sell of 0.40 % removes 0.20 %.
- The pressure never goes below zero.
- The dev wallet's own trades never move the pressure. A dev cannot buy an eruption.
The four eruptions
When the pressure reaches the threshold, the volcano erupts: one slice of the dev bag burns, the chamber empties, and the next threshold is twice as high.
| Eruption | Net pressure needed | Share of the reserve burned |
|---|---|---|
| E1 | 5 % of supply | 1 / 10 |
| E2 | 10 % of supply | 2 / 10 |
| E3 | 20 % of supply | 3 / 10 |
| E4 | 40 % of supply | 4 / 10 |
After the fourth eruption the volcano is spent. It stays on record and nothing more burns.
The dev bag plan
In the studio, the creator chooses the dev buy and the share of it reserved for the eruptions: 50 % by default. A creator can also reserve 0 %: then nothing burns, and the coin page says so in plain words. Otherwise the reserve is cut in four slices weighted 1, 2, 3, 4.
Before the coin exists, the creator's wallet signs the four burns, each with its own durable nonce. No key ever goes through Magma. When an eruption happens, Magma only sends the burn that was already signed.
Armed, Burned, Cancelled
- Armed: the burn is signed and waiting for its eruption.
- Burned: the eruption happened and the burn is confirmed on-chain, with its signature shown.
- Cancelled, in red: the dev sold part of the reserve or voided the signature, so the burn can no longer go out. The coin page says why.
The coin page also shows the dev bag live: reserved, free, burned and sold, in % of supply, and every dev sale with its time to the second.
What Magma never does
- It holds no funds. There is no treasury, no vault and no site wallet.
- It takes no fee. Stonks trading fees apply as on any Stonks coin: 1 % StonkFun and 0.25 % Raydium per trade, 0 % to the creator.
- It never sees a private key. Your wallet creates the coin and makes the dev buy in one transaction.
- It promises nothing about price. The mechanism burns dev tokens; it does not make a coin go up.
- It never fakes activity. Simulated coins are marked Simulated.
Check it yourself
The state of a volcano is a pure function of its trade history: same trades, same state. Each coin page replays the full history in your browser, with the same code the site uses, and shows the resulting state hash.
