What Astro does

• Play a crash game settled in USDG on Robinhood Chain
• Verify any round via a pre-committed hash chain plus a block-hash salt
• Deposit USDG into the ERC-4626 bankroll for ASTROLP shares on the house side
• Log in with email/social (embedded wallet) or connect your own wallet

The house edge is 3.03% (1-in-33 instant crash at 1.00x); bankroll LPs absorb the house's profit and loss, minus a dilution fee on deposit, an optional withdrawal fee and an operator fee on profit above the high-water mark.

Astro is a crash game: a multiplier climbs from 1x and a player cashes out before it breaks, or loses the stake. Fairness comes from a hash chain rather than a VRF: ten million seeds are pre-generated so that each is the hash of the next, the terminal hash is published on chain before any play, and the block hash of the closing transaction becomes that round's public salt. The protocol part is the open bankroll, an ERC-4626 vault taking USDG deposits and issuing ASTROLP shares that absorb the house's profit and loss, with exposure capped so a single bet can win at most 2% of the bankroll and a round at most 2.5%. A 2% fee is charged on deposit and an operator fee applies above a high-water mark. That vault is what DefiLlama counts, about $83k in September 2026. Caveats matter here: it is unaudited gambling by an anonymous team, the site requires an account rather than only a wallet, and round orchestration happens off chain between commit and reveal. Its docs now list the crash game, bankroll vault, provably-fair and access-controller contracts.
