- Claimed winnings go to your Overtime Account, which is controlled by your own wallet.
- Winnings not claimed within 90 days of a market being resolved are forfeit.
Fees (as published)

Key risks
- You can lose the full stake of a bet.
- The terms state that use involves smart contract risk and that the platform is provided as is, at your own risk.
- Sending tokens on an unsupported network to your Overtime Account address might lose your funds.
- Winnings not claimed within 90 days of resolution are forfeit.
- Each market has a risk limit, so liquidity on one side can run out.
