changeHow to buy Spark BTC with crypto: exchange and swap guide
Swap BTC, USDT, ETH or SOL for Bitcoin on Spark. Follow the $100 minimum, receiving-address checks and fixed-order payment steps.
1. Prepare a Spark receiving address
Copy the Spark mainnet address from the wallet that will receive your BTC. Use the wallet preparation guide if you are unsure which Receive option to select. ChangeSpark converts supported crypto assets; this order form does not accept bank transfers or card payments.
2. Choose the asset you already hold
Select the exact asset and network. BTC to Spark BTC uses Bitcoin mainnet for payment; USDT TRC20 to Spark BTC uses TRON. Ethereum ETH, Solana SOL and other supported USDT or USDC networks have their own directions. Your wallet’s withdrawal network must match the selected route.
3. Enter at least $100 worth of the sending asset
The minimum is checked in USD before the service fee. It is not a fixed number of SOL or BTC, and 100 units of a stablecoin are not assumed to equal exactly $100. If the input is below the threshold, the form says “Minimum exchange amount is $100.” The maximum depends on the available receiving reserve. Choose a slightly larger amount if price movements leave an estimate close to the minimum.
4. Review the quote and create the order
The standard service fee is 1%; a direction may have its own fee. Check the displayed outgoing charge and the receiving address. The calculator is a preview until the order is created successfully. The created order saves the rate and receiving amount. For the complete calculation, read exchange fees and limits.
5. Copy the payment details
Use the amount and deposit address from the new order. They can be copied on the payment page. Its QR code contains the address only, so enter the amount separately. Allow for your sending wallet’s own fee so the full requested amount reaches the destination. Pay within 60 minutes and save the private status link.
6. Follow confirmation and delivery
The order begins as Awaiting payment. After receipt confirmation it changes to Processing, then Completed when the outgoing transfer is marked sent. Arrival can depend on the receiving network and wallet. For a wrong amount, late payment or a review, use payment help and contact support with the CS order ID before sending again.
