Frequently asked questions
Accounts, isolated addresses, on-chain payments and fees.
Getting started
What can I do with Coinkun?
Create accounts with dedicated addresses, track balances and on-chain payments, send single or batch payouts and receive callbacks. Invoices include payment links and embedded checkout.
Which cryptocurrencies are supported?
Accounts, wallets and invoices support Bitcoin, Litecoin, TRX and USDT TRC20. Check the currency reference and your dashboard for enabled currencies and payout modes.
Do I need an email address to create an account?
No email or password is required. Account creation returns an Account ID and a one-time Transfer Key. Save the key securely.
Accounts and keys
What is the difference between an Account ID and a Transfer Key?
The Account ID lets you view balances and history. The Transfer Key authorizes protected actions and must stay private.
What if I lose my Transfer Key?
The Transfer Key is shown once and cannot be retrieved. Keep a secure backup; self-service recovery is not available.
Why does my account appear in the dropdown?
Remember accounts in Cookie settings saves up to 20 Account IDs in this browser. The list does not authorize payments. Clearing it does not delete accounts.
How long does dashboard unlock last?
Unlock lasts up to 10 minutes. Lock ends access immediately. Remembered Account IDs do not extend authorization.
Addresses and payments
Does each account have its own receiving addresses?
Yes. Each address belongs to one account. Addresses and balances are kept separate between accounts.
Is an address a private key?
No. Share a receiving address to request payment. Coinkun holds the signing keys; transfers require your authorization.
How are payments detected?
Bitcoin and Litecoin payments are detected in the mempool and new blocks. TRX and USDT TRC20 payments are detected in TRON blocks and become final after solidification. Detected payments appear in History and trigger configured callbacks.
What do History statuses mean?
For Bitcoin and Litecoin, Pending means seen in the mempool; Recorded means included in a block. Not seen means a transaction left the mempool and may return; Orphaned means its block was replaced. TRON uses pending and final states tied to block solidification. Outgoing transfers have separate statuses. Unverified balances show as unavailable, not zero.
Can I automate withdrawals?
Instant, Recurring and Threshold Auto Transfer are available where enabled. Your dashboard shows the activation requirements and supported settings for each currency.
Integration and fees
Which API version should I use?
Use /api/v1. The API reference lists supported endpoints and request and response examples.
Can I share or embed a payment page?
Yes. Create an invoice, share its payment link or embed checkout. Customers see a receiving address, QR code and payment status.
What are the service fees?
Receiving payments is free. Payouts use percentage or fixed pricing, where enabled; network fees are separate. Pricing lists current rates and free thresholds.
How do payment callbacks work?
Coinkun sends callbacks to your URL and retries unacknowledged deliveries. The dashboard shows delivery attempts and responses. Receipt and invoice callbacks have different acknowledgement rules; verify payment state through the API before fulfilling an order.
