A Syntethics (SNX) token transaction carried out on the Ethereum 13/03/2020 network had a fee of 656.04 ETH, equivalent to over $76,720.

The most impressive thing, however, is that the value of the tokens sent was zero.

The high rate was later announced in a CoinOne report as a consequence of a human error made by an exchange official.

The company has denied any connection with illegal transaction attempts and money laundering.

"It was a mistake due to recent changes in the system. We reorganized the protocols of the transaction testing process to avoid the same error," says the statement.
