Recover Ethereum Presale: Locked Out of ETH Wallet?
In short
An Ethereum presale wallet from 2014 normally requires its original JSON file and password. A private key exported earlier is a separate route and can remove the need to decrypt that file. A password alone cannot replace missing wallet data.
- Preserve the original file, often called ethereum_wallet_backup.json. Check its public ethaddr address without exposing the password or encrypted contents.
- Use tooling that explicitly supports the presale format; it is not the same as a standard Ethereum keystore, and generic JSON import may fail.
- If the password is forgotten, remembered patterns and the original keyboard layout help scope a search. If the file is missing, check old mail and backups and preserve the original drive before attempting data recovery.

You bought ETH in the 2014 presale and want to open the wallet again. Two things decide whether you can: the presale JSON file you were sent (usually named ethereum_wallet_backup.json) and the password you chose when you bought. With both, the wallet opens in software that still reads the presale format; with the file but not the password, the file becomes the target of a password search; and with a private key you extracted from the file years ago, you can import the key and skip the file. Without the file, the password on its own opens nothing.
People usually come to us at Crypto Recovers saying:
“I bought Ethereum presale in 2014, and now I want to access my old presale JSON file wallet, but I forgot the password to the file.”
What the presale was, and why the wallets are hard to open now
The Ethereum Foundation sold ETH for 42 days from July 22, 2014, before the network launched. The rate started at about 2,000 ETH per bitcoin and fell as the sale went on; 60 million ETH were sold at roughly $0.30 each. Every buyer received an encrypted JSON wallet file and set a password for it.
The difficulty today is age, not the format. Over more than a decade, passwords have been forgotten, files have disappeared with old computers and closed email accounts, and early wallet software such as Mist has been discontinued. Which of those pieces you still have decides whether the wallet can be opened.
What you Need for Ethereum Presale Recovery
Three items decide the route: the presale JSON file, the password or whatever you remember of it, and any private key you extracted from the file in the past. Check which of them you have before you install anything.
Ethereum Presale Wallet File
Participants received the JSON file after completing their purchase. It holds the encrypted seed from which the wallet’s private key is derived, together with the wallet’s Ethereum address. Copy the file before you do anything else, and keep the original untouched.
Password / Passphrase (or hints)
You set the password when you generated the wallet in 2014. If you no longer know it, write down what you do remember: its length, the kinds of characters the presale form required, and the words, dates and names you used at the time. A password search is built from exactly that.
Private Key(s)
Whenever no wallet file is available but you do still have the private key(s), recovering the funds might even be easier. You can just import those private keys into a compatible wallet.
The Methods to Recover Ethereum ETH Presale
The correct recovery method depends on what you still have:
- Using the .json file + password (the original method most people use).
- Using the private keys extracted from the decrypted .json file (an alternative or fallback method).
- Using help from crypto recovery services if you forgot the password or the file got corrupted.
Recovering an Ethereum presale wallet is easiest when you still have the original JSON file and know the correct password. Compatible software may then be used to decrypt the wallet. If you already have the corresponding private key, you can use it to migrate the ETH to a newly created wallet. Do not use Mist Wallet, as it has been discontinued.
Recover Your ETH Presale
How to Restore Your Ethereum Presale Wallet (Using Password & Json File) Step-by-step
During the Ethereum presale in 2014, participants received a JSON (usually called ethereum_wallet_backup.json) wallet file and created a password to encrypt it. These are normally the two main components needed to access the presale wallet. Because the format is now more than a decade old, you must use trusted software that specifically supports Ethereum presale JSON files like MyEtherWallet.
Follow the restoration steps:
Step 1: Locate Your Presale Wallet File.
It is usually named something like:
ethereum_wallet_backup.json
It may be found in old emails, USB drives, external hard drives, or cloud backups. If you cannot find it, try searching your computer for .json files.
Step 2: Install an Ethereum-compatible wallet
You need trusted software that supports the original Ethereum presale JSON format. MyEtherWallet may support compatible JSON files, but you should confirm current support before proceeding. Wallets such as Trust Wallet, MetaMask, Exodus and hardware wallets do not necessarily accept the original presale file directly. In those cases, the file must first be securely decrypted before the funds can be migrated.
Step 3: Import the JSON file
Important: never upload your wallet file to an unknown website or send it to someone without first verifying their identity and security procedures. Always confirm that you are using the official wallet software. For wallets containing substantial value, the recovery should preferably be performed in a trusted offline environment.
Using MyEtherWallet:
- Go to MyEtherWallet — always check you’re on the correct website.
- Click “Access my wallet” → Choose “Software” → Select “Keystore / JSON File”.
- Upload your ethereum_wallet_backup.json file.
- Enter your presale password when prompted.
Step 4: Unlock and verify
Once entered correctly, you’ll see your ETH wallet address. You can now see your balance and move ETH to a new, safer wallet.
Complications While Recovering Ethereum Presale?
When trying to access your ETH, you may notice that the software doesn’t let you in, even though all the components seem to be available or intact. Below are the most common reasons why your balance might appear empty.
You have the file, but the password will not come back
The presale form enforced complexity rules, so most 2014 passwords mix upper- and lower-case letters, numbers and symbols, and many were built from personal details, dates or phrases that meant something at the time. Two things to note before any search: the keyboard layout and language settings you used in 2014, and which of your other passwords from that period the presale one might have copied. Write both down; they are the raw material for the search described further down.
Here is more about how to recover the password for a .json file.
The file was on a computer you replaced, or in an email account you closed
Missing presale files usually went one of two ways. The computer that held the file was replaced or its drive failed, and no copy had been made. Or the file only ever existed behind the download link in the email from the Ethereum Foundation, and that account was closed years ago. Check every place a copy could have ended up before concluding it is gone: old laptops and external drives, USB sticks, cloud folders, and the mailbox of any address you used in 2014, including its archived and deleted mail.
The password looks right, but the file will not decrypt
If you typed the password on a non-English keyboard in 2014, the characters the presale form received may differ from the ones you remember: accents, special characters and a changed layout all produce a different password from the one you think you typed. Type the password into a plain text field on the layout you used then (QWERTY, AZERTY or QWERTZ) and compare it character by character before you conclude it is wrong.
The wallet was phished, or you bought more than once
Scammers went after presale buyers from the start: phishing sites, fake recovery services and malware took email logins and wallet files from people who had done nothing wrong. Before any search, look up the address in the file’s ethaddr field on Etherscan. If the ETH was moved out years ago, no password will bring it back, and no service can either.
Buyers who purchased more than once sometimes overwrote an earlier wallet file with a later one of the same name. If that may be you, look for files with the same name in different folders, emails and backups, and check the ethaddr of each one: the file you have may not be the one that holds the earlier purchase.
The only copy was on a drive that has since failed
Some participants kept a single copy of the file on one machine, and that machine has since been damaged, lost or stopped working. If the drive still exists, a deleted or unreadable file can sometimes be recovered from it, provided nothing has overwritten the data since. Stop using that computer or drive, do not reinstall or format it, and have it imaged before anyone tries anything else.
What Happens If You Forget Ethereum Presale Password?
If you have forgotten the presale password, the file will not decrypt until the exact password is entered. You can still try likely candidates by hand, one at a time, on a copy of the file.
Before you start trying, we recommend creating a list of password hints to make the process easier and faster. It may be one of the passwords you used for other wallets, apps or websites at the time. You may include symbols you mostly use when setting passwords, important dates, names and occasions.
If you get your password wrong:
- Check your keyboard settings. Caps Lock might be on, or your keyboard layout might have changed (for example, from QWERTY to AZERTY).
- Check your password managers.
- Look through old notes, devices, or files. In our experience, we’ve had multiple clients who found their passwords in old notes already after reaching out to us, even when they thought they were lost forever.
- Check if you saved the password in a browser or a password vault.
Often, creating a password hint list helps trigger your memory, and the correct password comes to mind. But if you still can’t enter it correctly, password recovery services may be the remaining route.
When you need password-recovery tools
Open-source password recovery tools exist for this search, but they require technical configuration and are easy to misconfigure. If that is not your world, this is exactly the case we take.
Successful password recovery usually relies on targeted password candidates, known patterns, dictionaries, rules and masks. Blindly trying every possible password is generally impractical, especially when the password is long or complex.
When the search is no longer a home job
Professional work makes sense in three situations, and each of them needs the file or the device that held it. The first is a forgotten password once your own candidates are exhausted: the search is then built from what you remember — the character classes the presale form required, the keyboard layout you typed on, the words, dates and substitutions you used elsewhere in 2014 — and run with rules and masks against a copy of the file. The second is a deleted file on a drive that still exists: the drive is imaged and searched for the file, which works only if nothing has overwritten the data. The third is a file that current software refuses to open because of its age.
Without the file there is nothing to search: the encrypted seed sits inside it, and a remembered password opens nothing on its own. If you still have the file, or the device it was on, an assessment can tell you whether a search is realistic before you commit to anything. Our guide to finding a legitimate crypto recovery company explains what to check before you hand the file to anyone.
FAQ: Ethereum Presale Recovery
How to recover Ethereum presale wallet?
Recovery starts with the original presale JSON file, which holds the encrypted seed the private key is derived from. If you also have the password, compatible software such as MyEtherWallet can decrypt the file and you can move the ETH to a newly created wallet. If the password is forgotten, the route is a targeted search built from what you remember — patterns, dictionaries, rules and masks — run against a copy of the file. Without the file there is nothing to decrypt.
What information do I need to recover my ETH presale funds?
Three things help: the presale JSON file (usually named something like ethereum_wallet_backup.json), everything you can still describe about the password — length, character types, dates and names you used, and the keyboard layout and language settings you had in 2014 — and any private key you may already have extracted from the file. A private key on its own can simply be imported into a compatible wallet. The password on its own is not enough, because the encrypted data lives in the file.
What happens if I enter the wrong password too many times while recovering Ethereum presale?
Entering an incorrect password does not normally lock or damage an Ethereum presale wallet. However, always preserve the original JSON file and perform recovery attempts using a verified copy. This protects the original data if software or hardware problems occur.
How can I verify if my presale wallet actually contains ETH?
The presale JSON file normally contains the Ethereum address in its ‘ethaddr’ field. You can check this public address using a blockchain explorer such as Etherscan without decrypting the wallet or moving any funds. Never enter your password or private key into a blockchain explorer.
Can I recover my wallet if I only have the password but lost the JSON file?
The password alone is not enough because the JSON file contains the encrypted data needed to derive the private key. If the file was deleted but the original storage device is still available, data recovery may sometimes be possible. Success cannot be guaranteed, especially if the data has been overwritten or removed by SSD TRIM.
Can I recover ETH presale funds without technical expertise?
Yes, but only if the required recovery material still exists. Follow the current instructions for the software you use carefully. If the file, password or restore process is unclear, get technical help before experimenting with the only copy.
