Why did a swap or transfer fail in KriptoK? The most common reasons and how to fix them. Learn the key concepts, practical steps and risks to check before.
Blockchain transactions can remain pending, be rejected before submission, revert after execution, expire, or encounter a cross-chain issue. The outcome and any fee charged depend on the network and the stage at which the problem occurred.
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: Review the quote, price impact, token liquidity, and current market conditions before changing slippage. A higher tolerance can increase the risk of receiving a worse execution price.
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 an amount below the maximum and leave enough native token for the fee estimate shown by the app. The required buffer changes with the network and transaction.
Cross-chain swaps involve more than one network or service and can take longer than a single-chain transaction. Completion time and fees vary with the route, bridge or provider, network conditions, and required confirmations.
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.
If a transaction is rejected before being submitted, a network fee may not be charged. If an onchain transaction is included but reverts, the transferred amount generally remains under your control, but the gas used for execution may still be charged. Cross-chain transactions can have additional intermediate states, so check the transaction hash and route status before taking further action.
