Ethereum vulnerable to frontrunners: Researcher

Published

on



Ethereum may be vulnerable to frontrunners according to Dan Robinson, a research partner with the crypto-asset investment firm Paradigm. 

Robinson said in a blog post, the design of Ethereum’s mempool, or a set of unconfirmed transactions, is where the vulnerability lies. He said arbitrage bots monitor pending transactions in the Ethereum mempool and attempt to exploit profitable opportunities created by them.

Arbitrage bots typically look for specific types of transactions in the mempool (such a DEX trade or an oracle update) and try to front-run them according to a predetermined algorithm. Frontrunners look for any transaction that they could profitably forward trade by copying it and replacing addresses with their own. They can even execute the transaction and copy profitable internal transactions generated by its execution trace.

The rescue plan

Robinson explained that he devised a plan to extract the money in cooperation with a team of smart contract engineers and another team of Ethereum security engineers. The plan was to confuse the transaction so that the bots could not detect that there was a connection to the Uniswap spouse.

But despite the efforts made, the plan did not succeed, and the money was seized by the frontrunners.

He concluded his post by stating the lessons he learned from the experience and also warning miners of a similar fate if they do not pay close attention.

Bitcoin hits $35K after Biden reveals infrastructure deal, Paraguay proposes BTC bill

Published

By


Bitcoin (BTC)  price received a boost as news that lawmakers in Paraguay plan to present a bill to make BTC legal tender spread across Twitter. Shortly after the unconfirmed news surfaced on Twitter, Bitcoin price rallied to $35,289 before slightly pulling back below the key short-term resistance level. 

While the cryptocurrency Fear and Greed Index still indicates a sentiment of Extreme Fear, it’s worth noting that the measure has risen from 14 on June 23 to 22 on June 24 as traders begin to view the drop below $29,000 and Bitcoin’s rising open interest as signs that the current corrective phase may have ended.

While traders’ sentiment may have improved slightly, Cointelegraph analyst Marcel Pechman suggested that investors could be waiting for the $6 billion in Bitcoin and Ether (ETH) quarterly futures and options to expire on June 25 before making a more decisive move.

Stocks reach new record highs, altcoins rally

The crypto market wasn’t the only market to rally today. Traditional markets also rose to new highs after U.S. President Joe Biden revealed that he had reached an agreement on a $953 billion bipartisan infrastructure spending plan with the Senate.

Following the announcement, the S&P 500 and Nasdaq each rallied to new record intraday highs and closed the day up 24.65 points and 97.98 points respectively, while the Dow gained more than 322 points on the day.

As one would expect, altcoins also surged higher as Bitcoin price and traditional markets moved higher. Ether (ETH) rallied back above the psychologically important $2,000 level, while Tron (TRX) and Celo gained 26% and 28% respectively. CELO’s move appears to be driven by the listing of its Celo Euro (cEUR) stablecoin on KuCoin exchange.
