Q: What is "Slippage"?

During the execution of an asset flash swap, the execution price may differ due to market volatility. "Slippage" represents the maximum price fluctuation that a user is willing to accept to complete the transaction. High slippage increases the probability of the transaction successfully executing, but it also causes the user to pay a higher cost to buy assets or sell assets at a lower price.

Q: Does OneKey App Flash Swap support cross-chain asset exchange?

Yes, OneKey App Flash Swap supports cross-chain transactions. You can select your target cross-chain network from the supported network list. OneKey App Flash Swap will help you optimize your transaction fee rate and select the best cross-chain asset flash swap path.

Q: Why did my transaction fail?

There can be many reasons for your transaction failure, such as network congestion, insufficient miner fees/gas fees, incorrect slippage settings, insufficient liquidity depth, etc. We recommend that you check the reason for the transaction failure, make adjustments according to the prompts, and try again. If you encounter any problems that require assistance, please do not hesitate to contact our Customer Support Team immediately.

Q: If the transaction fails, do I still need to pay network fees?

When you perform a OneKey App Flash Swap transaction, even if the transaction fails, you still need to pay the necessary network fees (also known as "miner fees" or "gas fees"). Regardless of success or failure, every transaction needs to be recorded and broadcast to the blockchain network by network validators/miners. The network fees you pay compensate the miners/validators for the computing resource consumption in bookkeeping. To avoid unnecessary fee consumption (failed transactions), before initiating a transaction, it is recommended to check the usage status of the network, set reasonable network fees and transaction slippage, and ensure that your wallet has sufficient balance to pay the network fees.
