Out of gas issue (ERC20) - Failed transactions

Out of gas issues can happen when Ethereum miners run out of gas while processing your transaction. This issue mainly affects ERC20 tokens transactions.

You can learn more about gas, gas limit and how fees work on Ethereum here.

What is Ledger doing to prevent "out of gas" issues?

  • Ledger Live automatically estimates the optimal fee required for your ETH and ERC20 transactions.
  • However, Ethereum transactions might still fail because of network congestion. Besides, some smart contracts involved in transferring ERC20 tokens consume lots of gas and might also cause your transaction to fail if the gas limit is set to low.
  • This can be prevented by using custom Ethereum transactions in Ledger Live. You can learn how to create custom transactions here.
