Spark (SPK) is available on both Ethereum and BNB Smart Chain, giving users flexibility in how they move the asset between wallets and platforms. Traders often swap SPK to consolidate holdings across networks or to reposition into other assets without going through a centralized exchange. Because SPK exists on two separate networks, selecting the correct network at the point of swap is an essential first step.
Before swapping Spark, confirm which network your receiving wallet or platform supports — SPK runs on both Ethereum and BNB Smart Chain, and sending to the wrong network can result in unrecoverable funds. Ethereum and BNB Smart Chain have different fee structures and settlement characteristics, so your choice of network can affect both the cost and the speed of the exchange. No memo or destination tag is required for SPK on either supported network. Confirmation times vary depending on network congestion at the time of the swap; Zest shows the estimated rate before you confirm so you can review all details, including the destination address and network, before committing.
