LaunchToken contracts are created per market and are not listed here. Each market's token address appears on its market page and in GET /api/markets.
External contracts
These are not Hash.fun contracts. Every address was verified on-chain and, for Uniswap v4, against Uniswap's official deployments list.
| Contract | Address | Notes |

canonical |
There is no Chainlink feed on Robinhood Chain. The keeper's sanity bound is a divergence check between two independent off-chain BTC/USD sources.
Ownership and roles
Every contract has a single owner using OpenZeppelin Ownable2Step. Keeper-driven contracts also have a keeper address, set by the owner. There is no role registry and no timelock.
| Action | Who |
|---|---|
| Register a mining coin, register a feed, set the keeper | owner |
| Push prices, reprice, refill, collect fees, pay holders, sweep, execute buyback | keeper |
| Mint or burn a mining coin | PegManager only |
| Launch a market, trade | anyone |
| Remove market liquidity | nobody |
Decimals
USDG has 6 decimals. Every mining coin, every market token, and $POW have 18 decimals. Feed prices are USD × 10^18 per whole coin.
