Frequently asked questions
Clear answers before you connect a wallet address.
The practical details about how Cryptanio handles blockchain events, payments, access and risk signals.
Does Cryptanio hold funds or private keys?
No. Cryptanio reads public blockchain data and sends operational events. Payments go directly to wallets you control, and Cryptanio does not require private keys.
Which networks are supported?
Cryptanio currently lists 23 networks: Bitcoin, Litecoin, Dogecoin, Bitcoin Cash, Dash, Ethereum, BNB Smart Chain, Base, Polygon, Avalanche, Optimism, Arbitrum, Solana, TRON, XRP Ledger, Stellar, Cosmos Hub, Osmosis, Injective, Celestia, Noble, TON and Cardano. Where marked “+ tokens”, supported assets on that network can also be monitored.
Does Cryptanio charge a percentage of each payment?
No. Cryptanio uses fixed plans and volume allowances rather than a percentage fee on turnover. The exact allowance and optional overage rules are shown on each service page.
How does Cryptanio decide that a transaction is confirmed?
Confirmation follows the rules of each network. Cryptanio exposes pending, confirmed and rolled-back states so your product can make decisions from explicit events rather than from silence.
Are crypto subscriptions automatic debits?
No. A customer approves each renewal payment in their own wallet. Cryptanio tracks the period, payment status, reminders and access events.
Does sanctions screening make the compliance decision for me?
No. Screening returns a signal and its data source to support your process. Your organisation remains responsible for the legal and compliance decision.
Can I use Cryptanio without building an integration?
Yes. Donation and one-off payment links can be created without code. API and signed webhooks are available when you need product integration.
Which website languages are available?
The marketing site is available in English, French, Spanish, Russian, German, Portuguese, Korean, Japanese and Simplified Chinese. English is the default language.
