The Trustless
On-Chain Lottery
for HYPE
Pick 5 numbers and a gold position. Win the progressive jackpot. Every draw is cryptographically verifiable — no server, no middleman, no trust required.
Why LiquidLottery
Built for trust,
designed for everyone
Every lottery decision — numbers, prizes, distribution — happens on-chain and can be independently verified by anyone, anytime.
Provably Fair — Chainlink VRF
Draw numbers are generated by Chainlink's Verifiable Random Function. The randomness is tamper-proof and verifiable on-chain by any third party.
Progressive Jackpot
50% of every ticket sold feeds the jackpot directly. Unclaimed jackpots roll over to the next round — prizes only grow.
Non-Custodial
Your HYPE stays in your wallet until you buy. Prizes are claimable any time — no one can freeze or confiscate your winnings.
Hyperliquid L1 Speed
Runs on HyperEVM (Chain ID 999) — Hyperliquid's blazing-fast EVM layer. Transactions confirm in milliseconds at near-zero gas cost.
Audited & Time-locked
UUPS upgradeable contract with a 72-hour upgrade timelock and 48-hour admin timelock. Emergency cancel protects players at all times.
How it works
Four steps,
fully transparent
STEP 01
Connect your wallet
Use MetaMask, Rainbow, Coinbase Wallet or any WalletConnect wallet. Switch to Hyperliquid L1 (Chain ID 999) — one click.
STEP 02
Pick your numbers
Choose 5 white numbers (1–90) and a gold number with a specific position (0–4). Each combination is stored permanently on-chain.
STEP 03
Wait for the draw
When the round closes, Chainlink VRF delivers a verifiable random seed. Drawn numbers are computed deterministically — anyone can verify.
STEP 04
Claim your prize
Prizes sit safely in the contract until you withdraw. No deadlines, no expiry — claim whenever you like.
Prize tiers
