Frequently asked

Is KŌINInft really self-custody?

Yes. Your keys are created and stored on your device only. We never hold them and cannot access your funds. That also means you — not we — are responsible for backing up your recovery phrase.

What happens if I lose my recovery phrase?

Your recovery phrase is the only way to restore your wallet. If it is lost, no one — including us — can recover it or your assets. Back it up and keep it offline and private. We will never ask you for it; anyone who does is trying to steal from you.

Which chains and marketplaces are supported?

At launch you can view and send NFTs across Ethereum, Base, Solana, and more, and buy and sell on Ethereum, Base, and Solana through leading marketplaces. More tradeable chains are added over time.

What does KŌINInft cost?

A flat 0.5% fee on buys, always shown before you confirm. No fee on sells or sends. Marketplace fees, royalties, and network gas are set by third parties and shown separately.

Can I buy crypto with a card?

Yes, through our licensed partner MoonPay, where available. Some regions are excluded by the provider; where that applies, you can still fund your wallet by receiving crypto to your address.

How do I stay safe?

Never share your recovery phrase. Review every signing prompt — KŌINInft decodes approvals and transfers into plain language and warns you before collection-wide approvals. If something looks wrong, cancel.

Still need help?
