Why did my crypto transaction fail?

Why Did My Crypto Transaction Fail?

Common reasons: (1) Not enough native coin (e.g. ETH) for gas. (2) Wrong network (e.g. sending ERC-20 on BSC). (3) Slippage too low on a swap (price moved). (4) Smart contract reverted (e.g. limit not met, approval missing). (5) Insufficient balance. Check the error message in your wallet or on the block explorer. If gas was too low, try again with higher gas. If you used the wrong network, the funds may be on another chain; check the correct explorer. You may still pay gas even for failed transactions on some chains.
