Deposits and withdrawals

Deposit testnet ETH once to create a trading balance. Orders use that balance, so your wallet does not need to submit a transaction for every order.

You can withdraw available funds to the wallet that owns the balance, including while the exchange is paused. There is no administrative withdrawal path.

Payouts and voided markets

A winning share pays 0.001 ETH; a losing share pays zero. If a market is voided, Above and Below each receive 0.0005 ETH per share. A balanced pair therefore receives its full 0.001 ETH value.

The contract records balances in whole gwei. One ETH equals 1,000,000,000 gwei; the application handles this conversion automatically.

Trading fees

Makers trade without a fee. Takers pay a fee based on the smaller side of the price, and the fee can never exceed 2%.

fee basis = min(price, 100 − price)
