A coin launch you take part in by keeping a browser tab open. Every rig in an era pays one price, every block wants a fresh proof from your device, and the pool opens at 1.5× what the last miners paid.
Leading zero bits, best so far
One price for everyone in an era.
0.040 SOLThis device hashes a fresh proof each block.

0.000006817 SOLTrading fees from every locked pool: half buys back and burns $HASH, 30 % goes to the coin's creator, 20 % to the treasury. The program has no instruction that sends a launch's SOL to the team.
about 17 minutes from lobby to pool
Full rulesName, ticker, image, the era 1 rig price, and a soft cap of at least 64 rigs and 1 SOL.
Five minutes to buy era 1 rigs. Pick SOLO, or DEGEN: wins eight times less often, pays eight times more. Miss the soft cap and everyone is refunded.
Three eras of seven 30-second blocks. Each block your device sends one SHA-256 presence proof per wallet. An overclock adds ×1.25 weight, paid in $HASH and burned.
Each block closes with a public VRF draw. Shares under the target win a fixed payout.
The rig price is the difficulty. Era 2 rigs cost half of era 1; era 3 halves again, scaled by crowd growth, ×½ to ×2.
Two minutes to register wins, then the pool opens at 1.5× the era 3 cost. Coins unlock over 20 minutes.
A rig mines the seven blocks of one era and then burns out. You buy it during the era before. Each era halves the reward and the price; era 3 also follows how much the crowd grew.
| Era | Coins per block | Rig price |
|---|---|---|
| 1 | 857 142 | P1, set by the creator |
| 2 | 428 571 | P1 / 2 |
| 3 | 214 285 | P2 / 2 × clamp(N2/N1, ½, 2) |
21 000 000 max supply. Half can be mined across the 21 blocks; the rest is reserved for the pool. Coins nobody mines are never minted.
Each block, your browser hunts for a nonce whose SHA-256 starts with 20 zero bits. That takes a few seconds on a modern phone. You get one forgiven miss per era. It stops people who buy and leave; it does not stop bots.
Test this deviceA share wins when its hash lands under the target. DEGEN rigs win eight times less often and are paid eight times more. If an era has under 64 rigs of weight, DEGEN rigs mine as SOLO.
K = min(100, W/8) · payout = R · m / (1.2 · K) · example: era 1, 420 rigs
95 % of rig SOL goes into the pool. The opening price is 1.5× what era 3 paid per expected coin. If the reserve can't cover that, the price goes up, never down.
hp3 = P3 · N3 / (7 · R3 / 1.2)
open = 1.5 · hp3
pool coins = min(reserve, pool SOL / open)
