Email support@koini.io — we read everything and reply as fast as we can, usually within one business day. Include the address you were watching (public address only — never send a seed phrase or private key; we will never ask for one).
No. Watching an address is read-only and structurally unable to move anything. A sale happens only when you sign it yourself, in your own wallet, after seeing the full quote.
Never. There is no seed screen, no key import, and no in-app signer. You connect your existing wallet with WalletConnect and approve there. Anyone asking for your seed phrase is trying to rob you — including anyone claiming to be us.
When the purchase is visible — a swap in your own wallet history, or a fill from your read-only exchange data or CSV — we use that real fill and label it high confidence. When it isn't visible, we show an estimate clearly labeled as the market price when the tokens arrived, not your fill, and you can enter your real cost. A missing record is shown as unknown — never as zero.
0.20% of the sale, shown in dollars on the confirm screen before you sign. That is the only revenue we take. No subscription, no custody, no hidden spread.
No. Before you sign, you can discard the quote freely. After your wallet confirms the transaction on-chain, it is final and cannot be reversed by KŌINIsell or anyone else.
Ethereum and Base today. Other chains show as not yet supported — never as a wrong balance. Solana is next.
Only so your real fills can price your positions. The key you create must be read-only; the app refuses trade or withdrawal permissions, the key is stored encrypted on your device only, and you can delete it any time in Settings.
No. KŌINIsell is informational — not tax advice and not a recommendation to sell. For tax filings, talk to your tax professional.
