A decade after Ethereum’s preliminary coin providing, which raised $18.5 million in Bitcoin by promoting roughly 60 million Ether, debates about whether or not completely different types of manipulation ways had been concerned nonetheless swirl in social media.
One principle questions whether or not the Ethereum founders double-spent traders’ funds to artificially inflate the success of the ICO whereas permitting them to shut the sale with a bigger share of Ether underneath their management.
Journal performed a joint investigation with Canada-based blockchain forensics specialists at Grey Wolf Analytics to find out whether or not the ICO included double-spending of Bitcoin, an exercise deemed fraudulent by the presale’s phrases and circumstances. The investigation particularly seemed for any Bitcoin that entered the presale pockets, was withdrawn after which looped again in.
Three batches of withdrawals happened through the sale. The Ethereum group pulled roughly 3,800 Bitcoin from the ICO deposit tackle, often known as the exodus pockets, claiming to make use of them to cowl operational prices and loans. Upon examination, some subsequent transactions associated to those outflows appeared to create loops wherein comparatively small portions of Bitcoin returned to the deposit tackle.
Nonetheless, the investigation discovered that though some transactions initially displayed double-spending traits, additional evaluation decided that the funds in query didn’t originate from the presale tackle.
“We concluded with a excessive diploma of certainty that this was not the identical BTC withdrawn from the exodus tackle, ” Chedi Mbaga, head of forensics at Grey Wolf, tells Journal.
Nonetheless, the investigation discovered some funds with illicit origins, suggesting that unhealthy actors used the Ethereum ICO to launder soiled Bitcoin for clear Ether.
In 2014, it was fairly simple to take part within the Ethereum ICO. All you wanted to take action was have some Bitcoin and an electronic mail tackle.
In a single instance, Grey Wolf’s forensic evaluation traced 499 Bitcoin — the second largest single buy within the ICO — to BTC-e, a now-defunct alternate infamous for serving illicit actors and laundering prison proceeds.
Though the investigation discovered no double spending in Ethereum’s presale, it was clear that no measures had been taken to restrict the sale of Ether to illicit actors.
The Ethereum Basis didn’t reply to requests for feedback.
Right here’s the place double-spending allegations can happen
Roughly 3,800 Bitcoin had been withdrawn from the presale pockets through the 42-day ICO in three batches. The path of certainly one of these outflows exhibits Bitcoin dispersed to a number of wallets, and inside a number of transactions, a pockets is seen transferring 53 Bitcoin into the exodus pockets “36PrZ1KHYMpqSyAQXSG8VwbUiq2EogxLo2.”
Moreover, there are a number of trails from the three batches of Bitcoin outflows that share these traits.
However Mbaga says that these trails could possibly be mistaken as double-spending incidents, and blockchain information unveil an opposing narrative.
First, the “1L1JRVExeKiqBU1pmvoyzCfRzCfEP64pBJ” tackle is recognized because the recipient tackle of the three batches of withdrawals. The primary batch was a 1,150 Bitcoin switch from the exodus pockets to 1L1J on August 11. From right here, the Bitcoin seems to disperse to numerous wallets.
Most of these Bitcoin had been despatched to a second pockets, which then transferred 592 Bitcoin to a 3rd pockets, and from there, 93 Bitcoin had been despatched to a fourth pockets.
The subsequent transaction is the place recycling allegations come up.
The next transaction by pockets 4 comprises deposits from seven completely different addresses and two receiving addresses: Recipient A and Recipient B.
Recipient A is subsequently seen sending 53 Bitcoin to the exodus tackle. With out context, this might seem as if the 53 Bitcoin circled again into the ICO pockets.
However Grey Wolf’s evaluation discovered that these Bitcoin hint again to the six different deposits inside the transaction involving pockets 4.
In the meantime, nearly all of the Bitcoin from pockets 4 was finally deposited to an Ethereum Basis pockets via Recipient B.
“These outflows (62.93 of the 93.313 BTC) traced from [wallet four] had been deposited to an Ethereum Basis pockets [and] we finally attributed the BTC deposited by [Recipient A] to completely different deposit paths within the backward hint,” Mbaga says.
He provides that the habits of the funds that moved from the exodus pockets through the presale mirrors that of funds and working prices moderately than nefarious actions.
Why was the Bitcoin withdrawn?
It’s not as if the Ethereum group secretly took out some funds through the sale to cowl present prices.
In truth, Ethereum co-founder Vitalik Buterin introduced the withdrawals earlier than they occurred to repay loans and working bills.
“The intent is to withdraw 4,150 BTC from our exodus tackle inside the subsequent 48 hours. We reserve the proper to withdraw as much as 850 BTC extra if wanted earlier than the top of the 42 day period of the sale, however at this level it’s doubtless that the rest of the BTC within the tackle will stay unused till the sale ends,” Buterin wrote in an August 8, 2014 weblog publish.

Blockchain transaction information exhibits that the Ethereum Basis withdrew lower than the introduced quantity (roughly 3,800 Bitcoin) through the presale interval, with the 1L1J pockets used to handle the funds.
Outdoors of what seems to be a $3 trial transaction, 1L1J has solely ever obtained funds from the exodus pockets through the presale. This tackle seems to have been created to facilitate operational outflows through the sale, as all funds had been rapidly emptied, and it was by no means used once more.
Of the overall 3,800 Bitcoin, Grey Wolf’s evaluation discovered a minimum of 1,000 Bitcoin had been both parked, deposited to exchanges or transferred to Ethereum group wallets in 15 transfers. The remainder of the Bitcoin continued transferring past 15 hops.
Phrases of the Ethereum ICO
The Ethereum presale was performed underneath Ethereum Switzerland (EthSuisse). Operations had been handed over to the Ethereum Basis after the ICO, with EthSuisse finally liquidated.
The ICO kicked off on July 22, 2014, and ran for 42 days, concluding on September 2. By the top, round 31,600 Bitcoin had been deposited into the exodus tackle for a complete sale of round 60 million Ether. Of that complete, an extra 9.9% of the presale was allotted to early contributors, and one other 9.9% was given to the Ethereum Basis.
The choice to allocate pre-mined tokens to the founding members was controversial, because it pushed the beginning provide of Ether to 72 million, with the group controlling a minimum of 16.7% of your entire provide. Because of this, about 60% of the 2024’s circulating provide of about 120 million Ether was distributed in its genesis block.
For the primary two weeks of the sale, 1 Ether was priced at 0.0005 Bitcoin, that means a single Bitcoin may purchase 2,000 Ether. Over the following 22 days, the quantity of Ether obtained per Bitcoin decreased by 30 Ether per day. Within the closing six days, 1 BTC would buy1,337 Ether.
To stop a single investor from buying a big portion of the token’s provide, EthSuisse restricted particular person purchases to 2 million ETH, although the phrases and circumstances state that giant purchasers may contact EthSuisse immediately for clearance.

Regardless, there was no strict strategy to implement these limits.
Any single entity may hypothetically make limitless purchases with a number of electronic mail addresses and repeat this as many occasions as they may afford to.
In the meantime, traders had been discouraged from immediately depositing to the presale pockets.
As an alternative, the ETH presale web site would generate a proxy pockets for ICO members to ship their Bitcoin. The funds had been then moved to the exodus pockets on behalf of traders. Which means that most traders didn’t management the wallets that immediately deposited the Bitcoin to the exodus pockets.
Grey Wolf discovered 9,000 complete inflows into the exodus pockets on the Bitcoin community.
Of these inflows, smaller purchases of 25 or fewer Bitcoin dominated the presale with 8,814 transactions. The second most frequent quantity vary was 26 to 50 Bitcoin in 98 transactions. The very best single buy was recorded for 699 Bitcoin and the second-highest for 499, which might be traced again to BTC-e.

Guests can nonetheless observe the presale prompts to generate a totally functioning Bitcoin pockets.
Journal generated a pockets via the Ethereum 2014 presale web page in June 2024 and despatched a really small quantity of Bitcoin to substantiate that the pockets is certainly useful. Journal has no management of the pockets.
Soiled Bitcoin, clear Ether
A case of illicit fund flows within the Ethereum ICO was revealed in November 2023 when the US Division of Justice seized 30,000 Ether ($54 million) from darknet drug seller Christopher Castelluzzo.
A few of the proceeds from Castelluzzo’s narcotics enterprise (which had been in Bitcoin) had been allegedly used to purchase Ether within the 2014 ICO. At the very best charge, Castelluzzo would have traded 15 Bitcoin for his 30,000 Ether.
The Justice Division acknowledged that in 2016, Castelluzzo obtained an extra 30,000 tokens of Ethereum Basic, a cryptocurrency representing the Ethereum blockchain that features information of The DAO hack, from which the present Ethereum blockchain forked to revert its damages.
Supporting this development, Journal and Grey Wolf’s investigation discovered trails that recommend illicit actors used the Ethereum ICO to clean their soiled Bitcoin in alternate for clear Ether.
Particularly, the second-largest single buy of 499 Bitcoin was tracked again to BTC-e, an alternate that was shut down by regulation enforcement in 2017. Launched in 2011, BTC-e was “one of many major methods by which cyber criminals transferred, laundered and saved prison proceeds,” based on the US Justice Division.
US authorities declare that the alternate was used to launder funds from the Mt. Gox hack.
In June 2023, the Justice Division charged Alexey Bilyuchenko and Aleksandr Verner with involvement within the Mt. Gox hack and with conspiring to launder the funds. Moreover, Bilyuchenko was charged with conspiring with Alexander Vinnik to function BTC-e from 2011 to 2017. Vinnik pleaded responsible in Could 2024.
The Mt. Gox hack got here to a crescendo in early 2014, and it’s potential that because of the lack of Anti-Moneuy Laundering or Know Your Buyer controls within the Ethereum presale, the proceeds from the theft might have been laundered, Mbaga says.
“It’s the priority that because of the lack of those controls, somebody may have put in soiled cash and obtained out clear ETH on the different finish,” he says.
Along with the second-largest single buy order within the Ethereum ICO, the investigation additionally discovered different Bitcoin deposits that path again to BTC-e, although these cases occurred in smaller volumes, akin to 5 to 10 Bitcoin, based on Mbaga.
Within the earlier days of the ICO, 10 Bitcoin would have purchased traders 20,000 Ethereum. That’s price about $68 million, as of June 28, 2024.
The place did all the opposite Bitcoin go?
The remaining proceeds from the Ethereum presale both ended up in dormant wallets or despatched to exchanges whereas a majority circled again to Ethereum Basis-linked wallets.
Other than the 1L1J tackle, three different wallets had been used to facilitate main outflows from the exodus pockets.

The remaining deposits occurred after the presale concluded and behavioral patterns recommend that every one three wallets belonged to the Ethereum group, Mbaga says.
The primary withdrawing pockets obtained about 1,202 Bitcoin from the exodus pockets. Grey Wolf traced these Bitcoin inside a 15-hop search depth and located that 428 of these cash had been both parked at a pockets that stayed dormant, despatched to exchanges or circled again to Ethereum-controlled addresses.
A second withdrawer, additionally belonging to the Ethereum Basis, was recognized as the most important direct recipient of the presale proceeds. It obtained 17,219 Bitcoin from the exodus account.
“From a habits evaluation perspective, the wallets performed noticeably completely different roles. The 1L1J tackle appeared to have been for upfront operational bills, with smaller alternate deposits and smaller particular person distributions throughout subsequent hops,” Mbaga says.
“[The first] was extra for smaller distributions, with a major proportion of these funds going again to group wallets. And [the second] was largely a pass-through pockets used for short-term storage.”
Lastly, a publicly identified Ethereum Basis tackle emptied the presale pockets by receiving 9,359 Bitcoin. It additionally obtained 14,888 of the 17,219 Bitcoin within the second pockets and, by September 2015, held 24,214 of the presale BTC proceeds.
Into the Ether
The success of Ethereum’s presale kicked off what is understood as we speak because the ICO growth of 2017, a interval the place cryptocurrency tasks efficiently raised tens of millions of {dollars} via the presale course of, although the strategy was additionally favored by scammers.
A decade later, Journal and Grey Wolf’s joint investigation discovered that Ethereum’s ICO might have created an surroundings for illicit actors to launder prison proceeds on the Bitcoin blockchain to current themselves with a contemporary alternative on Ethereum.
Some illicit actors that held on to their Ether noticed astronomical positive aspects prior to now decade, with Ether buying and selling at $3,380 on June 25, 2024. On the time of the presale, they had been bought for about $0.31 per coin.
In the meantime, the investigation concluded that the presale didn’t include double-spending of Bitcoin.
Three batches of outflows from the exodus pockets that had been withdrawn to cowl a backlog of prices raised considerations that among the token’s closing vacation spot could possibly be the identical as its origin.
Such double-spending would have allowed the founding group to get a head begin on Ether accumulation on prime of the 12 million tokens that they already obtained on the genesis block as a part of the challenge’s allocation technique.
The transactions on the Bitcoin community had been discovered to visually current potential double-spending actions, however nearer evaluation of the paths squashed such suspicions.
