Why did a swap or transfer fail in KriptoK? The most common reasons and how to fix them.
Blockchain transactions don't always complete instantly, and sometimes they fail. No need to panic - your funds aren't lost, the transaction just reverts. Here are the most common reasons and how to fix them.
When swapping, the difference between the quoted price and the price at execution is called slippage. If this difference exceeds your set tolerance, the transaction automatically cancels.
Fix: Increase your slippage tolerance in the Swap screen (try 1% or 2% instead of 0.5%). But be careful with highly volatile tokens.
Every blockchain transaction requires a gas fee paid to validators. If you don't have enough native token to cover it, the transaction won't go through.
Fix: Keep a small amount of the chain's native token in your wallet: ETH for Ethereum, SOL for Solana, BNB for BNB Chain, etc.
When swapping a chain's native token (like ETH, SOL, or BNB), don't tap "Max." The maximum amount leaves nothing for the gas fee, so the transaction fails.
Fix: Enter a slightly lower amount than max. For example, if you want to swap 1 ETH, try 0.99 or 0.98 ETH. You need to keep some balance for gas.
Swaps between different chains take longer than single-chain transactions and require higher gas fees. They can take anywhere from 5 to 20 minutes.
Fix: Don't panic. Check your transaction history - if it shows "Pending" or "Processing," wait a few more minutes. You can track the TX hash on a block explorer.
On chains like Ethereum, transactions can queue up or fail during peak periods. If gas prices are momentarily very high, waiting for a quieter period can be more economical.
A failed transaction doesn't lose your funds. They stay in your wallet. However, any gas fee spent on the attempt (if any) is not returned - that's the cost paid to the network for attempting the transaction.
