Replace Energy Coin was an ERC-20 token which was offered in May 2019. And closed sometime in late June 2019/ The goal was to raise $610,00 USD in funding. The ICO completed and apparently traded on a few obscure exchanges. In September of 2019 it lost all of its value on the fexpro exchange.
As they were touting their IPO they made some very bold claims about the future of this organization: Here are a few:
- Let’s help to save our planet from Global Warming, Air Pollution, Water Pollution, Hazardous Waste, Resource Mining etc by applying solar panel everywhere. Or by supporting our project of solar energy generator.
- Replace Energy Coin is going to help our planet by using solar panel to generate energy. Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.
- Replace Energy makes a tremendous amount of profit. 60% will be shared with all REC Token holders and directly transferred to the holders’ account.
- The main applications of solar energy technologies in Mexico have been for non-electric active solar system applications for space heating, water heating and drying crops. As in most countries, wind power development preceded solar power initially, due to the lower installation cost. Since solar power is not available during the night, and because wind power tends to be complementary to solar, a mix of both can be expected. Both require substantial storage to compensate for days with no wind and no sun. Batteries provide short term storage, and pumped hydroelectricity provides longer term storage. Mexico has been already in solar energy and we’ll make profit here.
Some of the claims were particularly alarming such as the company’s claim that they make a “tremendous amount” of profit. And that they would share 60% transferred directly to the holders account. And clearly from the source code which is included there is no such language in the actual smart contract.
The people behind this ICO is also somewhat mysterious. Some of them just used names like Mr. Michael or Adnan. Some didn’t even list their names at all. They did post some pictures though:
Their advisory board was kind of the same. People hiding behind nicknames like Mr. David, Mr. Fahman. The only one with something that looked like a real name was Mario Krenmayr who actually had a facebook page with photos that matched what was on their promotional site.
The company said, “REC mission is to make use of the transparency and fairness of the blockchain to solve these problems, making the flow of investment intended to improve the world more transparent“
on CoinCodex it was described as “Replace Energy Coin will help our planet generate energy through the use of solar panels. Solar energy is radiant Sun light and heat harnessed using a variety of ever-changing technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.“
The source code consisted of one solidity contract file. With one commit on github. It was 178 lines of code mostly comments. The source code was as follows:

}Their old website is permanently offline. The github repository is not being updated. Their coin lost almost all of its value 3 months after it started trading, and we don’t know for certain but something tells us to advise holders of the token not to hold your breath on profit distributions from the “tremendous amount” of profits this company has.
