How Mine Index works

What Mine Index is

$MIDX is a token on Solana, launched and traded through pump.fun, and paired with tokenized NVDA. Every trade of it pays a fee. The project's part of that fee is paid out to the wallets that hold $MIDX and have signed in — the miners — in tokenized NVDA, every epoch, in proportion to how much they hold and for how long.

There is no staking, no locking and no claim button. You hold the token in your own wallet, sign one message, and payouts arrive on their own. What feeds the payouts is trading volume: every trade adds to the next epoch's pot.

The mining rules

Signing in

Mining counts from the moment a wallet signs in on the miner page: one message signed with the wallet, which is free and needs no gas. Holding without signing in earns nothing. Signing in twice changes nothing. The signature proves the wallet is yours; it doesn't give the site any power over it.

Epochs and watches

Time is cut into epochs. The first epoch of the launch lasts 15 minutes, every one after it 10. Each epoch pays out what its own trades brought in; nothing is saved up. A watch is 24 epochs — four hours from the launch — and it's the clock the multiplier runs on.

Balance

Your balance is counted by the minute across the epoch, not at one moment: 1M held for the whole epoch counts fully, 1M bought a second before it ends counts as almost nothing. Every incoming transfer counts as a buy and every outgoing one as a sell, wherever it came from or went to, so a multiplier can't be moved between wallets.

One wallet mines with at most 3% of the supply — 30,000,000 $MIDX. While it holds more than that it earns nothing, and it can't sign in until it's back under. That keeps a single large holder from taking most of every payout.

Multiplier

Every wallet starts each watch at ×1. Holding adds 0.5 for every hour, up to ×3 at the end of the fourth hour. When the next watch starts, everyone drops back to ×1 and the climb starts again.

Say you hold 1,000,000 $MIDX and don't touch it. Over a watch it counts as more and more in every payout split:

Drag the marker: the multiplier climbs through the watch, resets at the boundary, and climbs again.

• Buying more dilutes the bonus above ×1 in proportion: ×2 on 1M plus another 1M makes ×1.5 on 2M. The bonus then keeps climbing from there.
• Selling leaves the multiplier as it is.

Weight and your share

weight = balance × multiplier, added up minute by minute over the epoch

When an epoch ends, every signed-in wallet's weight is computed from its transfer history, and the miners' share of the epoch's money is split in proportion: your share is your weight divided by everyone's. A wallet that holds nothing when the epoch ends gets nothing for that epoch, whatever it held earlier in it — so buying, holding for a few minutes and selling inside an epoch doesn't pay.

Payouts

What you're owed is paid in tokenized NVDA straight to your wallet, once it reaches the payout threshold (a working value of about $1 in NVDA). Payouts go out at the end of each epoch. If a transfer to a wallet is refused, that wallet is skipped and stays owed; the others are paid. How the payout is built is in How a payout is made.

Where the money comes from

Every trade of $MIDX on pump.fun pays a fee. The project's creator fee is 2%, and on a Custom Pair it's paid in the quote asset — tokenized NVDA. pump.fun keeps its own protocol fee on top; that part isn't ours.

The 2% is split on a fixed rule:

On $100,000 of volume the 2% creator fee is $2,000: $1,900 to the miners and $100 to the developer. Whether the volume comes from ten trades or ten thousand makes no difference; only the total does. pump.fun's protocol fee is charged separately on top.

The developer's share is used to buy back $MIDX and burn it, so that part of every trade's fee comes back into the token instead of leaving it.

How a payout is made

At the end of each epoch the payout is built from on-chain data, then sent:

1. Fees collected. The epoch's creator fees arrive as tokenized NVDA in the project's fee wallet.
2. Holders read from chain. Every wallet that holds $MIDX, and how long it has held, is read straight from Solana — there's no list to join beyond signing in once.
3. Weights computed. Each wallet's weight is its balance × watch multiplier, added up over the epoch and capped at 3% of the supply. The miners' 95% is divided by weight.
4. NVDA sent. The tokenized NVDA is sent to every eligible wallet. Each payout is a normal Solana transfer, visible on the explorer.

There's no keeper bot and no on-chain splitter contract: the holders are snapshotted from the chain and paid their share directly. Because every step reads from public data and every payout is a public transaction, anyone can reconcile an epoch's payouts against the fees it earned.

Contracts and addresses

Everything involved, on Solana. Each address links to Solscan; the ones marked "at launch" are filled in the moment the token is live. Always check the token address before you buy.

Checking it yourself

You don't have to trust the numbers on this page. On the explorer, open the fee wallet to watch the NVDA fees arrive, and open any epoch's payout transactions to see the NVDA go out to holders. Open the $MIDX mint to see the supply and who holds it. Everything the miner page shows is read from the same public data.

The rules for a payout are the ones in this document — with the token's transfer history and them, an epoch's split can be recomputed.
