Crypto Transaction Failed — Understanding Gas Errors
Common Crypto Transaction Failure Types
Four main failure categories: insufficient gas, incorrect network, token approval failures, and smart contract errors.
“Out of Gas” Error
You set a gas limit too low for the transaction to complete. The transaction is reverted but you still pay for gas used. Fix: set a higher gas limit — use the “High” estimate in your wallet.
“Execution Reverted” Error
The smart contract rejected the transaction based on internal logic. Common causes: insufficient liquidity, slippage tolerance too low, or interacting with a paused contract. Fix: increase slippage tolerance for DEX swaps.
“Insufficient Funds for Gas” Error
You do not have enough native token (ETH, BNB, SOL) to pay the transaction fee. Even when sending ERC-20 tokens, you need ETH in the same wallet to pay gas.
Wrong Network Error
Sending USDT on BSC to an ETH-only wallet address will fail or result in inaccessible funds. Always confirm both the token standard AND the network before sending.
Can You Recover Failed Transaction Gas Fees?
No. Gas fees for failed transactions are non-refundable — validators still processed your transaction before it failed. This is by design on all EVM-compatible chains.
