How it works

SLICEPAD is a launchpad on RH Chain where the trading fees of every coin go to the coin's holders, and the holders earn them by mining from their browser. Every buy and sell pays a tax that lands in the coin's prize pool in the same transaction. Every 30 seconds the pool pays a slice to the wallets that mined that round, in ETH, straight to their wallets. Nothing waits anywhere, nobody has to claim.

A coin starts on a bonding curve. When enough ETH is in, it graduates into a Uniswap v4 pool with locked liquidity, and the same fees keep flowing through a Uniswap v4 hook, swap by swap.

Fees

Fees are always taken in ETH, before and after graduation, and delivered in the trade's own transaction. The creator never receives the tax: it belongs to the miners.

The bonding curve

Each coin has 1,000,000,000 tokens, all of them on its curve at launch. The curve prices like a constant-product pool that starts as if it held 1.68 ETH: the more is bought, the higher the price. Buyers' ETH stays on the curve and is paid back to sellers. The creator holds nothing at launch, but can buy the first tokens in the launch transaction itself, at the launch price and before anyone else (up to 25% of the graduation threshold).

Anti-snipe: a buy in the same second as the launch pays 99% tax, halving about every 0.2 seconds and reaching zero after 3 seconds. The tax goes to the miners. The creator is always exempt and can exempt the other wallets they will buy with.

Graduation

When 4.2 ETH of real reserve is in, the curve is done. The buy that fills it is cut to what is left, the rest of the ETH is refunded, and in the same transaction the ETH and the reserved part of the supply are placed in a Uniswap v4 pool at the price of the curve's last trade. The liquidity position is held by a locker contract that has no withdraw function. Tokens that did not fit in the pool at that price are locked forever too.

From then on the coin trades on Uniswap v4 (through this site's router, or any other v4 router). The pool's own LP fee is zero; the SLICEPAD hook takes the tax to the miners and the 1% fee in ETH on every swap and sends them where they belong, in the swap's transaction.

Mining

Open a coin's page, paste your wallet address (no signature, no keys) and press Start mining. Your browser hashes with the GPU (WebGPU) or the CPU and sends proofs to the server. Each wallet gets its own difficulty, retargeted every round so it sends about one proof every 10 seconds however fast it is. The round's slice is split by the work each wallet proved.

To mine a coin you must hold a minimum amount of it, at the start and at the end of the round. The minimum depends on the market cap: a seat costs 100 dollars at a 100k market cap and grows with the square root of the market cap, so the amount of tokens falls smoothly as the coin grows.

Rounds and the slice

A round is 30 seconds. At the end of each round the pool pays 10% of itself, at most 0.25 ETH, split by work among the wallets that mined and still hold the minimum. Rounds are numbered one after another; a coin nobody mines does not post rounds, its pool just waits.

What the server can move is capped by the contract: one round per 30 seconds, 10% of the pool, 0.25 ETH. There is no withdraw function, no owner of the pool, no pause and no upgrade. Even a stolen server key can only pay out one round at a time, to the miners.

Lucky slice or burn the slice

What every 10th round does is chosen by the creator at launch, once, and never changes.

Lucky slice: the whole slice goes to one wallet drawn at random among the wallets that mined in it, one ticket per wallet whatever its hashrate. The list of tickets is committed on chain first; the winner is fixed by the hash of a block that did not exist yet at commit time, so nobody, the server included, can pick it. Anyone can settle the draw.

Burn the slice: nobody is paid that round. The round's slice buys the coin on the market (on the curve, or on Uniswap v4 after graduation) and every token bought is burned, so the supply shrinks for everyone who holds. The buy pays the coin's own tax like any trade, which goes back to the pool. If the buy cannot be made, the ETH simply stays in the pool.

Payouts

Payouts go to your wallet as ETH in the round's transaction. A wallet contract that refuses plain ETH gets wrapped ETH; if even that fails the amount becomes a credit you can withdraw from the pool contract. Amounts under 0.0005 ETH are carried over to the next round.

How to verify a round

Every round has a public results file at /api/round/<number>?token=<coin> with every miner, its proofs and its share. The keccak256 hash of that file is posted on chain with the payout (RoundPaid event, field resultsHash). Hash the file yourself and compare.

Launching a coin

One transaction on the launch page creates the token, its bonding curve and its prize pool, and opens trading. You choose the tax to the miners (1 to 9%) once; it can never change. You also choose what every 10th round does, once: Lucky slice (the whole round goes to one random miner) or Burn the slice (the round's ETH buys your coin on the market and burns it, so nobody is paid that round and the supply shrinks). You can buy the first tokens in the same transaction, at the launch price and before anyone else (up to 25% of the graduation threshold); beyond that you get no tokens and no share of the tax: your coin's holders do. What you get is a coin whose holders have a reason to hold and to trade.

Risks, honestly

• The contracts are new and not audited. The hook sits in the path of every swap after graduation.
• The mining server is centralized: it decides who mined how much. The contract limits how much it can pay, not to whom.
• Without volume there are no fees, and without fees there are no payouts. The pool pays 10% of itself per round, so it shrinks fast when trading stops.
• Coins launched here are launched by anyone. SLICEPAD does not vet them. A coin can go to zero.
