SCRATCHR Docs
Odds, mechanics and trust model — the whole placard, in writing.
Introduction
SCRATCHR is an on-chain scratch lottery on Robinhood Chain. You buy a ticket with ETH or $SCRATCH, scratch it, and prizes are paid in tokenized real stocks — NVDA, TSLA, GME and more — as ERC-20 tokens delivered to your wallet.
Odds & prize table
One odds table applies to every tier — higher tiers scale prize amounts, never probabilities. 55% of tickets pay something; the overall prize rate is 70% of ticket volume, pity included.
Result Odds GREEN $1 GOLD $5 OBSIDIAN $20 Zonk 45% — — — Dust 25% $0.40 $2 $8 Money back 18% $1 $5 $20 2x 9% $2 $10 $40 5x 2.7% $5 $25 $100 20x 0.29% $20 $100 $400 JACKPOT 500x 1 in 10,000 $500 $2,500 $10,000*
* OBSIDIAN jackpot pays from the progressive pot; while the pot is below max, the jackpot equals the current pot — always shown live. Pity: 10 consecutive zonks make the next scratch pay at least money-back, and the luck meter is displayed on screen.
Provably fair
Every roll is computed as HMAC-SHA256(serverSeed, clientSeed + ":" + nonce). The SHA-256 hash of the active server seed is published before any scratch uses it. Seeds rotate every 24 hours or 10,000 scratches, whichever comes first — the old seed is revealed at rotation.
- Your client seed defaults to a random string and can be changed any time.
- The verify page recomputes any historical roll in your browser — no API trust needed.
- Prize payouts are on-chain stock-token transfers from the public pool wallet, visible on Blockscout.
Balance, withdrawals & fees
Prizes are USD-denominated and accrue to your balance ledger. Each win is assigned a random stock from the prize pool (NVDA, TSLA, GME, AAPL, GOOGL, AMZN, META, PLTR, COIN, NFLX) at live market rate.
The X agent
Bind your wallet to your X handle once (one signed message on the web app — the agent never holds your keys). Then commands are tweets, and reveals are public replies with a verify link.

- Limits: 50 scratches per day via X, 30s cooldown between command tweets.
- Minimum X account age: 3 months (anti-bot).
- The same commands work in the Telegram bot.
$SCRATCH & THE CLUB
Odds are identical for everyone. $SCRATCH buys volume, access and prestige — never probability.
Pool wallet & security
- The prize pool hot wallet and cold treasury addresses are published — audit solvency any time on Robinhood Chain.
- Withdrawals under $100 are instant and automated; the hot wallet has a daily outflow cap.
- Launch policy: 100% of pons.family creator fees seed the prize pool for the first 30 days (then 50/50 with treasury).
- SCRATCHR never custodies your wallet — deposits are transfers you sign, prizes are tokens you receive.
