How does staking work?+
You commit real money to your own performance. Every participant in a challenge puts funds into a shared pool held in escrow. When the challenge ends, athletes who successfully completed it split the pool from those who didn't. Complete — you get your stake back plus a share of what the losers left behind. Quit or fail — your funds are forfeited to the winners. No exceptions.
How exactly do winners make money?+
Winners collect their original stake back in full, plus a proportional share of the forfeited funds from everyone who failed or quit. The more people who drop out, the bigger the payout for those who finished. Your cut is calculated based on your stake relative to the total winning pool. The platform takes a small service fee — the remainder goes entirely to the athletes who earned it.
What happens to losers' money?+
When an athlete fails to meet the challenge requirements by the deadline, their staked funds are forfeited. Those funds are distributed among the verified winners at the end of the challenge period. There is no partial refund, no grace period, and no appeals process. If you didn't complete it to spec — you didn't complete it.
What if something happened outside of my control?+
That's on you. Mr Syn is built on accountability and discipline — not sympathy. Whether it's an injury, a family emergency, a car accident, or anything else — the outcome is the same. Your staked funds will only ever be returned in the event of a successful, verified completion that meets the challenge requirements. Life happens. That's exactly the point. The stakes are real because the commitment has to be real.
What types of challenges are available?+
Mr Syn supports running, weight-loss, strength, cycling, and custom performance challenges. You set the goal, the duration, the proof requirements, and how much you want on the line. Challenges can be head-to-head, group, or solo time trials.
How is completion verified?+
Verification depends on the challenge type. GPS-tracked activities are verified via live route data. Weight and body composition challenges require app-connected weigh-ins or photo submissions. AI-powered checkpoints flag inconsistencies automatically. Manual review is available for disputes, but the burden of proof is always on the athlete.
Is my money safe while the challenge runs?+
All staked funds are held in escrow for the duration of the challenge. Your money is never at risk of loss due to platform issues — payouts are processed within 1–3 business days after challenge close.
Can I withdraw my stake once a challenge starts?+
No. Once a challenge begins and your stake is committed, it is locked. Withdrawing is not an option — that would defeat the purpose. If you leave or stop participating, your funds go to the winners at the end.
What's the minimum stake?+
Challenges start from $5. There's no upper limit — high-stakes challenges are available for serious competitors who want real skin in the game.
Is Mr Syn available in my country?+
Mr Syn is currently available in Canada and the United States. More regions are coming. Check the app store listing for current availability.
