Flow verifiers are asked to stop working after the chain is returned.
DeBridge founder Alex Smirnov has urged validators on the Flow blockchain to stop processing transactions until the Flow Foundation comes up with a remediation plan for users affected by the chain's controversial return.
The refund is in response to a $3.9 million theft on December 27, when an attacker exploited a flaw in Flow's execution layer to withdraw funds through multiple chain bridges.
DeBridge is one of Flow's main bridge providers and asked Smirnov to explain plans to resolve duplicate balances for users who have terminated Flow during the return window.
While Flow validators have yet to accept Smirnov's call, data from Flowscan shows that the Flow blockchain is stuck at block height 137,385,824, as of 11:24 pm UTC on Saturday.
At the same time, the Flow Foundation said the blockchain is expected to restart in the next four to six hours. The exploit and Flow's roll back caused the FLOW token to drop 42% after the attack, according to CoinGecko data.
Raises a roll argument.
Off-chain reversion is controversial because it undermines trust in the network's decentralization and security by reversing verified transactions and creating uncertainty in user account balances.
Smirnov protested the “hasty decision” that Flue failed to inform Economists that he would return the chain, and argued that the return of the chain would cause more financial damage than the initial exploitation.
“The rollback introduces strategic issues affecting bridges, maintainers, users and partners who have worked faithfully during the affected window.”
This flow includes crypto exchanges that list the token, which Smirnov said could put them in a difficult position when it comes to deposits and withdrawals during the waiting window.
Gabriel Shapiro, general counsel at crypto investment firm Delphi Labs, argued against the flu's approach, saying they're “creating non-backed assets to cover their asses and waiting for bridges and issuers to take the hit or do their own separate recovery.”
Dapper Labs, the creator of the Flow blockchain, responded to the widespread criticism by saying that no user balances or assets, including the Dapper Labs treasury, were affected.
Cointelegraph reached out for further comment but did not receive an immediate response.

Flow was launched in 2020 by Dapper Labs, and the team received $725 million in funding from the likes of Andreessen “a16z” Horowitz and Union Square Ventures to advance the ecosystem.
Flow fell short of expectations, with $85.5 million in value locked up in the blockchain, while FLOW fell short of the top 300 tokens in the market at $167.3 million.
