Buying and selling ETHPoW tokens might open customers to danger of dropping Mainnet $ETH


Warning: There’s a danger of relay assaults on particular person customers’ wallets if the ETHPoW ChainID isn’t up to date as deliberate. Such assaults will trigger customers to lose $ETH equal to the ETHPoW offered.

Latest issues over The Merge have been exacerbated after discovering that the Ethereum proof-of-work chain had not up to date its ChainID to a novel quantity. The staff behind ETHPoW up to date its GitHub on Friday morning to state that it could use the ChainID ‘10001’ after the Merge.

Nevertheless, the staff asserted that the ChainID would stay at ‘1’ (the identical as Ethereum Mainnet) till the day of The Merge in response to Coinbase requesting or not it’s up to date.

“The code you talked about within the above feedback has to maintain as a result of chainID 1 is required to validate chain knowledge for blocks earlier than the merge, and all chain knowledge after the merge can be chainID 10001.”

Ought to ETHPoW retain the identical ChainID and nonce as Mainnet, customers might danger dropping funds after they attempt to commerce any ETHPoW tokens they might obtain.

CryptoSlate spoke to Temoc Webber and Igor Mandrigin, CEO and CTO of Gateway.fm respectively in regards to the potential for relay assaults by way of the ETHPoW chain. Gateway.fm is a web3 infrastructure firm centered on constructing decentralized RPC options that don’t depend on centralized providers comparable to AWS.

Throughout the dialog, Mandrigin acknowledged that there’s “no cause” for the ETHPoW staff to not replace the code earlier than The Merge. “They might fork it immediately,” he asserted earlier than suggesting a easy resolution:

“You possibly can merely add some code that permits ETHPoW to make use of ChainID till the TTD of The Merge is reached after which routinely revert to a ChainID of ‘10001.’”

Including just a few easy traces of code would enable the Ethereum group to loosen up, figuring out that ETHPoW isn’t making ready to create chaos on Mainnet post-merge. Nevertheless, the other seems to be confirmed as a core Ethereum developer, Lefteris Karapetsas, was blocked by EthereumPoW’s Twitter account after mentioning the problems with not altering the ChainID in good time.

If the ChainID and nonce of ETHPoW usually are not up to date, then any trades that happen on the ETHPoW chain may very well be replicated on Mainnet. Right here is an instance of how this may very well be exploited.

  1. A malicious actor units up an empty upgradeable proxy good contract on Ethereum Mainnet previous to The Merge.
  2. After The Merge, the malicious actor upgrades the ETHPoW good contract to permit customers to promote their ETHPoW at a premium of $500 per ETHPoW.
  3. On Ethereum Mainnet, the malicious actor upgrades the good contract to ship any ETH it receives to Twister Money.
  4. The ETHPoW good contract is marketed as the most effective DEX to commerce ETHPoW, and customers promote their ETHPoW for USDT for $500 per ETHPoW.
  5. The commerce additionally goes by way of on the Ethereum Mainnet, on condition that the identical ChainID, nonce, and personal keys are an identical. Nevertheless, the Mainnet contract has been up to date to ship the ETH to Twister Money and never return any USDT.
  6. The consumer now has USDT on ETHPoW and nothing of their Mainnet pockets. On condition that USDT doesn’t help ETHPoW, the consumer has basically been rugged of their ETHPoW and ETH.

A phrase of warning for anybody planning to dump any ETHPoW tokens they obtain after The Merge.

Take note of whether or not the ChainID of ETHPoW has been up to date earlier than you transact. The ChainID ought to NOT be ‘1’ however ‘10001.’ If the ChainID is ‘1’, you danger dropping funds out of your Mainnet Ethereum pockets.
