FAQ

Common questions

Is Queen One available now?

Queen One is currently in early access. Sign up for a free account to get immediate access to wallet management, NFT browsing, and basic DeFi features.

Which blockchains does Queen One support?

We currently support Ethereum, Solana, Polygon, Arbitrum, Optimism, Base, Avalanche, BNB Chain, and several others — with more being added monthly.

Does Queen One hold my crypto?

No. Queen One is non-custodial. You retain full ownership and control of your assets at all times. We provide the interface, not the vault.

Is there an API for developers?

Yes — API access is available on our Enterprise plan. Contact our partnerships team to discuss integration options and licensing terms.
