A round

The grid has 25 blocks, numbered 1 to 25. Pick one or more blocks and deploy the same amount of ETH on each. The first deploy of a round starts the timer. The window is read from the contract and is 60 seconds on mainnet.

When the timer ends the round locks and no one can deploy any more. A random output picks one winning block. Miners on the winning block share the prize pool in proportion to the ETH they deployed on it.

Where the ETH goes

• 90% of all ETH deployed in the round is the prize pool for the winning block.
• 9% goes to the treasury, which also pays the randomness fee of each round.
• 1% goes to the jackpot.

ETH deployed on blocks that do not win is not returned. A round that is cancelled refunds every deploy in full, with no fee.

A round with no winner

If nobody deployed on the winning block, the round has no winner. The 9% and the 1% are still taken as in any round. The 90% prize pool is not paid out: it rolls over and is added to the pool of the next round that has a winner, where it is shared by the miners on that winning block. Several empty rounds in a row add up.

• ETH deployed on blocks that did not win is not returned in a round that settled.
• No POTS is minted for a round without a winner.
• Deploys are refunded in full only when a round is cancelled (see below).

Auto plans

An auto plan deploys the same blocks, with the same amount on each, in each of the next rounds. You pay the whole plan when you start it, from 1 to 100 rounds, and the ETH waits in the plan contract until its round comes. There is no plan fee.

• You can stop the plan at any time and take back the ETH that is not yet deployed. ETH already deployed in a round follows the normal round rules.
• The scheduler enters the round for you. It cannot change your blocks or amount, and it can only place the deploys of your plan. Only you can take the ETH back, with Stop auto.
• While a plan is active, the scheduler also opens the next round, so a round can start a few seconds after the last one is settled.
• Loop rewards, when you turn it on, moves the ETH you won in the plan's last round into the plan. It needs a separate permission from your wallet, and you can turn it off at any time.
• A plan ends when its ETH no longer covers one more round. Stop it then to take back what is left. A round that cannot take the deploy is skipped. Outcomes stay random and a plan does not improve your odds.

Referrals and burn

A wallet can have one referrer. It is set once, for good, and only before the wallet deploys for the first time. You cannot refer yourself. When a referred wallet claims POTS, the contract mints an extra 1% of that claim to the referrer. The referred wallet pays nothing and gets the same reward as anyone else, and no ETH is involved.

Anyone can burn POTS they hold from the Token page. A burn is permanent and lowers the total supply. It does not lower the total ever minted, so the cap is counted on the amount ever minted and a burn never makes room for more POTS.

Who can stop what

• Nobody can deploy for you, move your ETH, or change your claim. Taking part is your choice in every round.
• The owner (a multisig on mainnet) can pause new deploys. While paused, claims, refunds, settlement, and cancellations of stuck rounds keep working, so a pause never locks funds. The owner can withdraw the treasury share, but not deploys, unclaimed prizes, the rollover, or the jackpot. The owner cannot change the rules, the amounts, or the odds (they are fixed when the contract is deployed), cannot mint POTS, and cannot cancel a healthy round.
• Anyone can move a round forward: start it, lock it, request the random output, and settle it. The app does this on a schedule, and if the schedule stops, any person can do it (the Operator page lists the steps).
• A round that gets stuck can be cancelled by anyone after a waiting time: 1 hour after it locked, or 1 day after the random output was requested without an answer (mainnet defaults). Every deploy of that round is then refunded in full.
• The randomness fee is paid from the treasury. If the treasury cannot cover it, the round waits until anyone tops the treasury up; deploys already made stay safe in the contract.

Jackpot

Each settled round that has miners on the winning block has a 1 in 625 chance of a jackpot hit. On a hit the whole jackpot goes to the miners on the winning block, by the same shares. The odds are set in the contract. 1 in 625 is the current default and is provisional until the contracts are audited.

POTS token

Every settled round with miners on the winning block mints 1 POTS, split by the same shares. Total supply is capped at 1,000,000,000 POTS. At 1 POTS per round the cap is not reached in practice. The Token page shows the live values from the contract. This page and the app make no statement about price or value.

Claims

Rewards are claimed by you, one ETH claim and one POTS claim per round. There is no expiry. A failed claim for one wallet never blocks other wallets or other rounds.

Limits

Each block has a minimum and a maximum deploy. The current mainnet defaults are 0.001 ETH to 0.05 ETH per block; the maximum is provisional until the contracts are audited. The contract checks the amount, the block list, and the deadline when your transaction is included, so a transaction sent close to the deadline can fail.
