Fees

A protocol fee applies to buys and sells, and a small sell fee stays in the market’s pool. The Kash web app shows the exact fees before you confirm. Creating a market costs at least $20. This provides the market’s initial liquidity and is not returned to the creator.
Every Solana transaction has a small network fee in SOL. ZeroID pays it for you, so you never need SOL. On web trades and claims, a small amount is charged back in USDC, and the web app shows it before you confirm. Trades placed on X skip it.

Trades

You trade against the market’s automated market maker, so there’s no counterparty to wait for. Each trade is quoted before you confirm and executes on Solana from your own self-custodial wallet. See Custom AMM.
A trade can’t be cancelled once it executes. To change your position, sell some or all of it, or buy more, any time before trading closes.
Common reasons:
  • The price moved past your quote before execution (slippage protection stopped the trade)
  • Trading has closed: the market froze, resolved or was cancelled
  • Insufficient USDC for the amount plus fees
  • Trading isn’t available in your region
A failed trade doesn’t take your USDC. Refresh the quote and try again.

Claims and refunds

When a market resolves, winning positions appear under Claimable in Portfolio. Claim a position, or use Claim all. For cancelled markets, tap Claim refund. See Redeeming positions.
When a market resolves, the winning outcome’s positions can be redeemed. The trade ticket’s estimated payout if your outcome wins is your best guide.

Withdrawals

Crypto withdrawals complete once the transfer confirms on Solana, and you can follow the status in the web app. An exchange may take longer to credit you.
It clears automatically and you can try again.

Tracking and problems

Portfolio → Transactions lists your trades, claims, deposits and transfers, and Portfolio → Withdrawals tracks withdrawals. Each on-chain transaction links to its details, so you can verify it on Solana.
On-chain transfers can’t be reversed. If you sent to an exchange on the wrong network, contact the exchange, as they can sometimes recover it. If you sent the wrong token or network to your self-custodial wallet address, report it from the info button in the web app → Feedback → Report a bug with the transaction details.
Report it from the info button in the web app → Feedback → Report a bug with the time, amount and transaction link, or ask in Discord.
