error_36 Input address is not checksummed
(error_36) Input address is not checksummed when sending from MEW or an Exchange
Sometimes you will get the following error when Ether or ERC20 tokens from MEW (MyEtherWallet) to an other Address.
This error appears because the ETH address you would like to send coins to is not checksummed.
What does that mean? Is it dangerous?
Don’t worry. The answer and solution is very simple.
‘What Does ‘Not Checksummed’ Mean? Why are Some Letters Capitalized?
Every Ethereum address has two versions. One version has some letters as uppercase characters and the other version doesn’t.
As an example:
- Non-checksummed version: 0xdecaf9cd2367cdbb726e904cd6397edfcae6068d
- Checksummed version: 0xDECAF9CD2367cdbb726E904cD6397eDFcAe6068D
Even though both addresses use the same charachters and lead to the same place, the checksummed address is more accurate in determing if the address is a correct one.
Even though you can still use the non-checksummed address, it is recommended to use a checksummed address so that the payment gateway (MEW or an Exchange) can determine if the address you want to send the funds to is real.
4 Simple Steps to transform an ETH address into a Checksummed one
Step 1: Head to etherscan.io
Step 2: Input the address you’re interested in viewing into the search field
Step 3: You will be taken to a page for the address, with balances and a list of transactions
Step 4: At the top of the page, see the checksummed version with capital letters included
Now you can copy your newly checksummed address and paste it into your address field where you want to perform the transaction.
Hint: Always check the address you want to send the funds to.
