Show HN: ETHShot – an Ethereum test‑net "take‑your‑shot" jackpot game Hi HN, I’ve been tinkering with ultra‑simple blockchain games and built ETHShot.io, a tiny dApp where each “shot” at a jackpot costs 0.0005 test‑ETH and has a 1 % chance to win the whole pot. It’s live only on the Sepolia/Goerli testnets, so no real ETH is involved. How it works - Connect a testnet wallet (MetaMask, Rabby, etc.). - Each transaction (“shot”) sends 0.0005 test‑ETH to the contract. - On every shot there’s exactly a 1 % chance the contract pays the entire pot to the sender. - Non‑winning shots add to the pot minus a small maintenance fee. 0 Contract is under 80 lines of Solidity; front‑end is plain Svelte. Source code: https://ift.tt/Rlcywv8 . I’m looking for feedback on - Usability and onboarding (is the flow obvious?). - Contract design, gas savings, and any attack surface you spot. - Whether the 1 % odds feel right or should be dynamic. Quick start - Grab a little test‑ETH from any Sepolia faucet. - Visit https://ethshot.io and take a shot. - If you win, you’ll see the transaction immediately; if not, you’ll see the pot grow. - Bug reports and ideas welcome here or as GitHub issues. Thanks for taking a look. — Anthony (cranberryturkey) July 23, 2025 at 10:07PM
