Frequently Asked Questions

Everything you need to know about exchanging with OneChainCrypto.

Getting Started

Yes. A free account takes less than a minute to create and lets you track orders in real time, save wallet addresses and keep a full history of every exchange.

Minimums depend on the currency pair but generally start around the equivalent of 20 USD. The calculator shows you the exact minimum as you type.

We support 24+ assets including BTC, ETH, USDT (ERC20 and TRC20), BNB, SOL, XRP, TON, ADA, DOGE and many more.

Orders & Delivery

Most orders complete within five to twenty minutes after your payment confirms. Network congestion on the sending side can occasionally add delays.

Once your deposit transaction is broadcast on-chain, orders cannot be cancelled because blockchain transfers are irreversible. Contact support immediately if you sent a wrong amount and we will do our best.

Do not worry. If the amount is higher than quoted we deliver the extra value at current rates. If it is lower we deliver what arrived minus fees, or refund if below our minimum threshold.

Your deposit goes directly to our liquidity provider which sends the destination coin straight back to your wallet. We never hold user funds longer than the order takes.

Fees & Rates

Never. The amount shown in the calculator already includes our service fee of roughly 0.5%. What you see is what you get.

Rates are aggregated in real time from multiple global liquidity sources so you always receive a fair market price with no artificial markup.

Crypto markets move continuously. Your final amount reflects the rate at the moment your deposit confirmed on-chain, not the moment you clicked Exchange.

Security & Privacy

Small transactions require no identity verification. For larger amounts or when required by our providers, verification may be requested in line with AML regulations.

All traffic is encrypted with bank-grade SSL, card data is handled under PCI DSS by our payment partners, and we never sell personal information.

Addresses are used solely to process your order. They are never shared with third parties for marketing purposes.
