Why did my transaction fail?

Though there are several possible reasons:

  • Not enough ether on origination account to perform transfer and pay for gas
  • Nonce is too high or too low
  • Signature is incorrect
  • Transaction gas consumption exceeds block gas limit

Tell me more about “gas”

Ethereum Gas – is the lifeblood of the Ethereum ecosystem, there is no other way of putting that. Gas is a unit that measures the amount of computational effort that it will take to execute certain operations.

Every single operation that takes part in Ethereum, be it a simple transaction, or a smart contract, takes some amount of gas. Gas is what is used to calculate the amount of fees that need to be paid to the network in order to execute an operation.
