In July 2014, Ethereum’s core developers opened a historic presale of their new ether (ETH) cryptocurrency to interested investors. At the time, anyone who wanted to invest in the Ethereum Foundation’s vision of a “decentralized internet” could have visited the official website, created an Ethereum presale wallet, and purchased ETH with Bitcoin (BTC).

According to news reports, it only took one day for early Ethereum adopters to trade over $2 million worth of BTC. At the end of the 42-day sale, the Ethereum Foundation raised an impressive $18.3 million and recorded 6,670 transactions with 51,000,213.9 ETH sold. Considering Ethereum is now the second-largest cryptocurrency, it’s safe to say the ETH presale was one of the most lucrative investment opportunities in crypto market history.

However, since the Ethereum developers encrypted each presale investor’s private key to a JSON file with a unique password, people who didn’t store this info properly couldn’t claim their crypto once the Ethereum blockchain went live in 2015. Sadly, there are many unfortunate stories of people still struggling to access a ton of ETH stuck in their Ethereum presale wallets.

If you’re having issues with Ethereum presale wallet recovery, know there are troubleshooting strategies and expert wallet recovery services to regain access to your cryptocurrency. Keep reading to learn the methods you can use to recover your ETH.

The Basics of ETH Wallet Set-up

The Ethereum presale wallet is an encrypted JSON file that the Ethereum Foundation offered to crypto investors in 2014. Each of these files contains the essential private key for a new Ethereum address, which users could use to import the ETH they purchased during the presale to the Ethereum blockchain once it went live. The only way to decrypt the private key on an ETH presale wallet’s JSON file is to use the password users created during the presale wallet set-up process.

To better understand how the Ethereum presale wallet works, let’s quickly run through what people had to do to claim ETH when this wallet came out. Between July 22nd and September 2nd of 2014,’s homepage had a few countdown clocks and a button on the bottom to “Buy Ether.” For the first 14 days, one BTC equaled 2,000 ETH, and this figure gradually diminished until 1,337 ETH equaled one BTC at the end of the presale.

If users clicked the “Buy Ether” button, they had to read and agree to the Terms & Conditions statements.

From here, users entered how much BTC they wanted to trade for ETH, with the minimum set at 0.01 BTC and the max at 500,000 BTC. Users then needed to enter an email address and create a password for their account. The Ethereum Foundation warned users they would need their password to recover their presale wallet.

Common Reasons for Losing Access to Ethereum Presale Wallets

As we’ve helped people regain access to their Ethereum presale wallets, we’ve run across a few common issues people have accessing their ETH. While there could be dozens of potential problems with your presale wallet, chances are you’re having trouble with one of the following situations.

Misplaced or Forgotten Password

Arguably, the most common reason people can’t get into the Ethereum presale wallet is that they don’t know their password. Whether you forgot where you stored the password, you can’t remember it, or the info you have isn’t correct, you can’t decrypt your wallet’s private key without this crucial info.

Lost JSON File

Along with the password, the JSON file associated with an Ethereum presale wallet is essential to claiming your ETH. Remember, each JSON file contains the private key for your wallet, so you need this information to access your ETH on the Ethereum blockchain. Unfortunately, some people deleted this file from their email or lost access to it on the computer they downloaded it on.

A Bug In The ETH Wallet’s Software

Working with various clients, we’ve identified a few bugs, glitches, and other issues with Ethereum’s code which make it impossible for early investors to access their presale wallet. For instance, in one case, an ETH presale wallet owner couldn’t get into their account because of foreign characters they used during setup. Even though this client knew their password, the presence of these foreign characters prevented the decryption process.

Hard Drive Corruption

In addition to software issues, a few investors have trouble because there’s a problem with the computer they used to download their JSON file. If there’s an issue with the computer’s hardware, like a damaged hard drive, then there’s a risk you can’t reclaim the crypto you downloaded during the set-up process.

Phishing Scams or Hacks

Since the Ethereum presale was a major success, it attracted many scammers into the crypto industry. Indeed, during the presale, the Ethereum developer community pointed out the rise in fraudulent social media profiles and sites claiming to offer premined ETH. Some early investors might have lost their presale Ethereum wallet due to a cyberattack or a scam.

Recovering the ETH in your presale wallet depends on how much info you have to start with. Ideally, you’ll have both your JSON file and the correct password to your account to import the private key to an Ethereum-compatible crypto wallet. However, even if you’re missing one of these elements, there are alternative techniques and crypto recovery services which can get into Ethereum presale wallets.

Ethereum Presale Wallet Recovery With the JSON File and Password

  • Include upper and lowercase letters
  • Include symbols
  • Screened against frequently used and insecure passwords
