Bitcoin on Spark. One clear starting point.
Spark BTC means bitcoin held and transferred on Spark. ChangeSpark lets you exchange supported crypto for BTC on that network and exchange back. Start with what Bitcoin on Spark is, then choose a direction from the exchange catalog.
How a Spark BTC swap works
Prepare a Spark receiving address, enter at least $100 worth of the sending asset and review your quote. Your output amount becomes fixed when you create the order. Send the exact payment and follow its status through confirmation and delivery. The Spark BTC swap guide walks through each step.
Rates, fees and supported networks
BTC and BTC on Spark use a 1:1 conversion before fees; cross-asset directions use market conversion. The displayed service fee and outgoing network charge determine your receiving amount. The fees and limits page explains the calculation and reserve-based maximum.
Wallet transfers, bridges and Lightning
A Spark transfer, a Bitcoin mainnet deposit and a Lightning payment use different instructions. Compare Spark Bitcoin bridge options, prepare a compatible wallet and check Spark vs Lightning before sending. Spark’s payment speed does not replace the confirmation steps of an exchange order.

Clear answers.
Networks, fixed quotes and help with your payment.
Read the Spark Bitcoin guide ↗What is Spark BTC?
Spark BTC is bitcoin held and transferred on the Spark network. It is not a separate investment token issued by ChangeSpark. For a Spark receiving route, use a Spark mainnet address from your wallet.
What is the minimum exchange amount?
The minimum is $100 USD worth of the sending asset, before the service fee. The calculator checks its current USD value. The maximum depends on the available receiving reserve.
Which assets and networks can I exchange?
Choose Bitcoin on Spark, Bitcoin, Ethereum, BNB on BNB Smart Chain, Solana, TRON, and the supported USDT and USDC networks. The exchange catalog lists each enabled direction. Always match the asset and the network.
When is my exchange rate fixed?
The calculator previews your exchange. The rate and receiving amount are fixed when you create an order, with the service fee and displayed outgoing network charge included. Send the exact payment within the 60-minute payment window.
How long does an exchange take?
Your order moves from awaiting payment to processing, then completed. Processing starts after payment receipt is confirmed. Network confirmations and payment checks affect completion time. Follow your private order page or contact our 24/7 support team.
Do I need an account?
No account, email address or Telegram username is required to create an order. Save your private order link to return to its status. If you need help, give support the CS order ID rather than the private link.
What if my payment is late or the amount is wrong?
Contact [email protected] or live chat with your order ID. Do not send a second payment until support reviews the first. An expired order does not prove a late blockchain transfer failed.
Is ChangeSpark a DEX or a trustless bridge?
ChangeSpark is an exchange service: you send the selected asset to the service, then receive the chosen output after payment confirmation. It does not provide a decentralized exchange or a trustless bridge contract.
