Hey Product Hunt! I'm Gareth, the maker of Gauntlet. The idea came from a simple frustration: fitness accountability is broken. I've made verbal bets with friends a dozen times — "loser buys dinner if I don't hit 50km this week" — and they never actually happen. Nobody tracks it, nobody pays up. Gauntlet makes those bets real. Connect Strava, pick a challenge (run/cycle/swim), set the distance, stake some USDC, and your friend accepts. Strava data auto-verifies the result. Winner gets paid on-chain. No manual settlement, no "I forgot", no awkward chasing. The tech: on-chain USDC on Base, Strava webhooks for automated verification, non-custodial so we never hold your money. The whole payout flow runs on-chain — we just trigger it. I've been running it for a few months. The behavioral effect is real — even a $10 stake changes how seriously you take a run. Loss aversion is a more powerful motivator than any fitness app streak. It's free to join. You only put money in when you enter a challenge. Happy to answer any questions — ask me anything about the tech, the design decisions, or what's coming next. And if you try it, I'd love feedback. gauntlet.bet
