How hashpad.fun works

hashpad.fun is a token launchpad on Robinhood Chain. Every market launched on it is quoted in a unit of Bitcoin's production economy rather than in a stablecoin, and the holders of every market are paid trading fees in that same unit.

A mining coin is an ERC-20 token with 18 decimals whose price tracks one unit of Bitcoin's production economy. Every market on hashpad.fun is paired against one of them, and every holder reward is paid in one of them.

A market is launched from one form and one transaction. The creator picks a name, a symbol, an image, a mining coin to pair against, a fee between 1% and 3%, and a first buy. The contract mints the full supply, opens the Uniswap v4 pool, places both liquidity positions, and executes the first buy, all in the same call.

Every hashpad.fun market is a plain Uniswap v4 pool from the transaction that creates it. The whole token supply is placed in that pool as concentrated liquidity in the same call, and no contract or account can take it out again. The bonding curve is the shape of the liquidity, and the liquidity is real.

Every trade on hashpad.fun goes through the LaunchRouter. You pay in ETH, USDG, or a mining coin; the router crosses whatever pools sit between your asset and the market and settles in one transaction.

Every swap in a market pool pays the LP fee the creator chose at launch, between 1% and 3%. The fee accrues to the two liquidity positions the launchpad owns. Every 15 minutes the keeper collects it, and the treasury writes it to a ledger in a fixed split.

Holding a market token pays you a share of that market's trading fees, in the market's pair coin, every 15 minutes. There is nothing to claim. The coin is transferred to your wallet.

$HASHPAD is the protocol token of hashpad.fun. It is launched on Pons, the token launchpad of Robinhood Chain, with a fixed supply of 1,000,000,000 that can only decrease. Two streams of ETH buy $HASHPAD and burn it: 30% of the fees collected from every hashpad.fun market, and the creator fees that $HASHPAD itself earns on Pons.

The keeper is a single off-chain process that does the recurring work the contracts cannot do for themselves: fetching prices, repricing pegs, collecting fees, paying holders, and executing the buyback. It never holds user funds. Every action it takes is a public transaction from the keeper address, and every transaction hash is logged.

hashpad.fun is one set of Solidity contracts, built with Foundry on Solidity 0.8.26, deployed to Robinhood Chain. The addresses below are the live deployment.
