The long-anticipated transition of Ethereum from Proof-of-Work (PoW) to Proof-of-Stake (PoS), commonly referred to as "The Merge," is drawing near—expected around September 10, 2025. As this pivotal upgrade approaches, speculation around a potential hard fork has intensified. Will Ethereum split into two chains? And if so, who will support which version?
With major exchanges, influential projects, and crypto thought leaders beginning to declare their positions, the stage is set for what could become one of the most consequential moments in blockchain history.
The Exchange Landscape: Diverging Strategies
As user-facing gateways to digital assets, cryptocurrency exchanges play a critical role in determining the legitimacy and liquidity of any forked chain. Their responses vary widely—from proactive support to cautious neutrality.
Gate.io: Early Support with Flexible Redemption
Gate.io has emerged as one of the first major platforms to openly prepare for a potential Ethereum split. In an official announcement, the exchange revealed it would enable ETH holders to convert their holdings into either ETHS (representing the new PoS chain) or ETHW (representing a potential PoW continuation) at a 1:1 ratio between August 9 and the successful completion of the upgrade.
Crucially, Gate.io added a safety net: if the hard fork fails, ETHS tokens will automatically revert back to standard ETH, and all related trading markets will be delisted. This approach balances opportunity with risk mitigation, giving users options without locking them in prematurely.
Poloniex: Backing Both Chains with Futures Support
Poloniex, operating under the Tron ecosystem, has taken a more aggressive stance by pledging full support for both the upgraded PoS chain and any viable PoW fork. The exchange confirmed that users holding ETH at the time of the fork will receive an equal amount of the new forked asset.
Moreover, Poloniex is preparing infrastructure ahead of time—announcing plans to list futures contracts for the potential PoW chain, signaling confidence in its tradability and market demand.
Huobi: Setting High Standards for Legitimacy
Huobi Global has adopted a principled yet neutral position. While respecting community consensus, the exchange explicitly discourages forks lacking genuine innovation or technical improvements. It opposes pre-mining and insists on strict criteria before recognizing any new chain:
- Advance notice and formal communication with Huobi
- Built-in two-way replay protection
- Chain immutability (cannot be overwritten by the original)
- Distinct transaction formats requiring wallet upgrades
- Publicly tested client software released prior to activation
These standards aim to filter out speculative forks and promote long-term network stability.
OKX: Monitoring Demand Closely
OKX CEO Jay Hao emphasized the platform’s commitment to supporting The Merge. However, regarding potential forked tokens, OKX remains flexible—stating it will evaluate listing decisions based on user demand and ecosystem adoption. This wait-and-see strategy allows OKX to respond dynamically while avoiding premature endorsements.
BitMEX: Betting on PoW with Derivatives
BitMEX made headlines by launching an ETHPoW perpetual futures contract (ETHPOWZ22) settled in USDT (ERC-20), offering up to 2x leverage. By creating financial instruments tied to the hypothetical PoW chain, BitMEX is effectively enabling traders to speculate on its survival—even before it exists.
Notably, giants like Binance, Coinbase, and KuCoin have remained silent so far, likely waiting to assess developer sentiment, stablecoin alignment, and overall network continuity before taking sides.
Project Sentiment: Strong Preference for PoS
While exchanges weigh market opportunities, core ecosystem projects are largely unified in their support for the PoS transition—and opposition to a PoW split.
Chainlink: Full Alignment with The Merge
Chainlink reaffirmed that its oracle network will continue operating exclusively on the post-merge Ethereum blockchain. The team stated clearly: they do not support any PoW fork, aligning with the broader Ethereum community’s vision.
Argent & DeBank: No Plans to Support Forks
Popular smart contract wallet Argent expressed enthusiasm for The Merge but confirmed no intention to support alternative chains. Similarly, DeBank, a leading DeFi dashboard, warned that a hard fork could bring "massive disaster" to the Web3 ecosystem and pledged no support for PoW derivatives.
Frax Finance: Governance-Driven Clarity
Frax Finance co-founder Sam Kazemian proposed a governance vote urging FRAX DAO to recognize only the PoS Ethereum chain as legitimate post-merge. Given Frax’s significant footprint—ranked among top stablecoins with deep integration across Curve and Uniswap—this move adds substantial weight to the pro-PoS camp.
“As a key pillar of the Ethereum ecosystem, it’s vital we use governance to express clear intent,” the proposal noted.
Expert Opinions: Is a PoW Fork Viable?
Crypto analyst Jack Niewold, founder of Crypto Pragmatist, calls the idea of a successful PoW fork an "Ethereum civil war"—one likely doomed by lack of consensus.
He argues that without developer activity, media attention, or real-world liquidity, a PoW chain would quickly become a “ghost town.” Most critically, he highlights the stablecoin dilemma—a point echoed by Vitalik Buterin.
If USDT or USDC were to back both chains, issuers would face double liability for every token in circulation. Alternatively, choosing one chain over another could trigger massive arbitrage plays—such as shorting PoS ETH while redeeming on the PoW side for billions in profit.
While theoretically possible, such actions would risk legal consequences and ecosystem collapse. Still, Niewold warns: "With billions at stake, you can afford a great lawyer—or a private island."
Market Signals: stETH Discount Hints at Uncertainty
Even before any fork occurs, markets are reacting. stETH, Lido’s liquid staking derivative, currently trades at a 3.7% discount to ETH. This reflects investor caution about withdrawal timelines and potential fragmentation risks during The Merge.
Frequently Asked Questions (FAQ)
Q: What is the difference between ETHS and ETHW?
A: ETHS represents the token on the upgraded PoS Ethereum chain; ETHW refers to a potential continuation of the legacy PoW chain. Only one may survive long-term.
Q: Will I automatically receive forked tokens?
A: If a hard fork occurs and your exchange supports it, you’ll typically receive 1:1 forked tokens based on your ETH balance at the snapshot time.
Q: Are PoW forks dangerous for stablecoins?
A: Yes. A split creates dual liabilities for centralized stablecoin issuers like USDT/USDC. Their choice of chain will heavily influence which network gains dominance.
Q: Can I lose money during an Ethereum fork?
A: Direct loss is unlikely if you follow proper security practices. However, price volatility, smart contract risks, and replay attacks (without protection) can pose threats.
Q: Why do most projects oppose a PoW fork?
A: Because it fragments liquidity, weakens network effects, and undermines years of progress toward scalability and sustainability via The Merge.
Q: What happens if no one supports the PoW chain?
A: It may continue mining briefly but will likely suffer from low hash rate, poor security, minimal DeFi integration, and eventual irrelevance.

The Ethereum hard fork debate isn’t just technical—it’s economic, social, and political. While some players see profit in division, most of the ecosystem is rallying behind unity under PoS. As September approaches, all eyes will be on stablecoin issuers, core developers, and whether speculation turns into reality.
One thing is certain: whichever chain retains developer momentum, DeFi liquidity, and community trust will be recognized as the Ethereum.
