Hi Etheremon trainers,

To make transaction success with low fee, you need to understand about gas price and gas limit, there is a very good document about that at https://myetherwallet.github.io/knowledge-base/gas/what-is-gas-ethereum.html. If you do not have time to read it, here is a quick note from me:

Transaction fee = (Gas limit * Gas price) Gas limit: If you reduce gas limit, your transaction can be fail and you will see the error “Out of gas”. You can set gas limit higher than normal to ensure it can go through. All unused gas is refunded to you at the end of a transaction. “Cash out” function on our website requests higher gas limit when you have more Etheremons. Hence, please increase gas limit to a higher value if you have a lot of Etheremons (some users need to use 3000000, in the next update we will try to fix this issue). Here is an example of fail transaction due to out of gas:

3. Gas price: the price you pay for each unit increases or decreases how quickly your transaction will be mined. If you set it too low, it can take forever. To ensure that you do not set it too low, you can check what a safe value is at https://ethgasstation.info/.

Conclusion: you can increase Gas limit to ensure you don’t get “out of gas” error, please reduce Gas price to reduce your transaction fee (but do not set too low, check https://ethgasstation.info/ to get a suitable value).
