The app

The Boom Doom app is the website where you play: connect your wallet, watch the live BTC price, place your bets, and claim winnings. Everything you need is in one place.

What you see

Live price chart — The main area shows the BTC/USD price updating in real time. When a round is live, a horizontal line marks the "lock" price (the price at which the round started). Green above the line means price is up, red below means down.

Countdown & bet panel — The timer shows how long until the current round closes. You choose your stake (min 0.001 SOL, max depends on House Vault liquidity), pick BOOM or DOOM, and confirm in your wallet. After you bet, the panel shows your active bet and potential payout until the round ends.

Result & claim — When the round ends you see WIN, LOSE, or PUSH. If you won (or pushed), your winnings are credited to your UserVault. You can withdraw from your UserVault to your wallet at any time. Your history and the leaderboard are available from the footer links.

Wallet connection

To play with real SOL you need a Web3 wallet on Solana Mainnet. Click Connect Wallet and choose Phantom, Solflare, Trust Wallet, or another supported Solana wallet. Make sure you have some SOL for bets and transaction fees. The app only works on Solana Mainnet.

UserVault

Each player has a UserVault account that holds SOL for betting and stores winnings. You'll need to deposit SOL into your UserVault before placing bets. When you win, your payout is credited to your UserVault, and you can withdraw to your wallet at any time.

Sim Mode

You can try the app without connecting a wallet. In Sim Mode the price comes from real Pyth data and "bets" are not sent on-chain — useful to get a feel for the interface before playing with real funds.
