The Ethereum network’s long-anticipated transition from proof-of-work (PoW) to proof-of-stake (PoS)—commonly known as "the Merge"—has prompted major shifts across the decentralized finance (DeFi) ecosystem. Among the most notable responses is a governance proposal initiated by the Aave community to temporarily suspend ETH lending in anticipation of potential network volatility. This strategic move underscores the protocol’s commitment to risk mitigation, user protection, and long-term stability during one of the most significant upgrades in blockchain history.
Why Pause ETH Lending Before the Merge?
As Ethereum prepares for its consensus overhaul, DeFi protocols are proactively addressing risks associated with potential chain forks and market instability. Aave, one of the largest decentralized lending platforms, is no exception. In response to concerns raised by risk analysis firm Block Analitica, the community launched a formal governance vote to pause ETH borrowing on the platform prior to the Merge.

The core concern? High utilization rates in the ETH lending market could trigger a cascade of negative outcomes, including:
- Difficulty or impossibility of liquidations
- Negative annual percentage yields (APYs) for stETH/ETH positions
- Mass withdrawals by ETH suppliers seeking to avoid exposure
Block Analitica warned that unchecked demand could destabilize the lending pool, putting both borrowers and lenders at risk. To prevent this, they recommended an aggressive adjustment to Aave’s interest rate model—specifically, raising the variable borrow rate to 1,000% at 100% utilization. This steep curve would act as a natural deterrent against over-leveraging, effectively discouraging excessive borrowing just before the network transition.
While the full pause proposal gained traction, Gauntlet Network—a key contributor to Aave’s risk framework—suggested a two-phase approach. Their alternative strategy involved splitting the decision into separate votes: one for pausing ETH borrowing and another for adjusting interest rates. This method allows for more granular control and community input on each component of the risk mitigation plan.
Aave DAO’s Stance: Supporting Ethereum PoS Exclusively
In a landmark decision earlier this month, the Aave community formally declared its support for Ethereum’s proof-of-stake chain—effectively rejecting any potential PoW fork that might emerge post-Merge.
This position was solidified through an Aave Request for Comments (ARC) proposal, which established that:
- Aave DAO will operate exclusively on the PoS version of Ethereum
- Any forks running on alternative consensus mechanisms (e.g., PoW) will not be supported
- Guardian roles within the DAO are authorized to disable Aave deployments on non-PoS chains
This strategic alignment ensures that Aave’s total value locked (TVL) remains secure and unified on a single, widely adopted chain. By rejecting fragmentation, the protocol avoids diluting liquidity and mitigates risks tied to competing networks with uncertain futures.
With Aave V3 already deployed and tested on Ropsten and Goerli—testnets that have successfully undergone their own Merge simulations—the development team has confirmed full compatibility with Ethereum’s new consensus mechanism. Developers agree that a PoW-based fork would lack the infrastructure and community support needed to sustain a viable Aave market.
How Centralized Exchanges Are Responding
While DeFi protocols like Aave take governance-driven actions, centralized exchanges are implementing operational safeguards to ensure smooth transitions.
Binance and Coinbase Issue Pre-Merge Updates
Binance announced a temporary suspension of ETH and ERC-20 token deposits and withdrawals during the upgrade window—initially expected around mid-September 2025. The exchange emphasized that these measures are precautionary, designed to protect user funds during periods of network uncertainty.
Crucially, Binance confirmed it would support any forked tokens resulting from a chain split. In such a scenario:
- The PoS chain will retain the ETH ticker
- Users will receive forked tokens (e.g., ETHW or similar) based on a snapshot of their balances prior to the upgrade
- These new tokens must pass Binance’s rigorous listing review process before trading begins
The exchange also reserved the right to adjust its approach based on evolving conditions—a reminder that outcomes remain uncertain despite careful planning.
Coinbase echoed similar sentiments in its own announcement, stating it would evaluate potential forked assets using the same standards applied to all new listings. Other platforms—including BitMEX and Poloniex—have also shared their contingency plans, reflecting industry-wide coordination ahead of the Merge.

Addressing Concerns About Decentralization and Censorship
Recent events have intensified debates around decentralization, particularly after Aave implemented transaction screening in compliance with U.S. Office of Foreign Assets Control (OFAC) guidelines. Following sanctions on Tornado Cash, Aave began blocking access to its front-end for addresses flagged by TRM Labs’ API—even affecting dormant wallets with no active transactions.
This move sparked controversy, impacting high-profile users like Tron founder Justin Sun. In response, Aave founder Stani Kulechov clarified that these restrictions apply only to the front-end interface, not the underlying smart contracts.
He emphasized that:
“Aave’s smart contracts are fully decentralized. No individual or entity can unilaterally alter, control, update, or terminate them without DAO consensus.”
Any changes to the protocol’s core functionality require approval through the Aave DAO governance process. This ensures that censorship-resistant principles remain intact while allowing the community to respond responsibly to regulatory developments.
Frequently Asked Questions (FAQ)
Q: Why is Aave pausing ETH lending before the Merge?
A: To prevent market instability caused by high utilization rates, which could lead to failed liquidations, negative yields, and mass withdrawals. The pause is a risk mitigation strategy endorsed by top analysts.
Q: Will I lose access to my funds if ETH lending is paused?
A: No. Users can still deposit and withdraw ETH. The restriction only applies to new borrowing activity. Existing loans remain unaffected.
Q: Does Aave support both Ethereum PoS and PoW chains?
A: No. The Aave DAO has officially committed to supporting only the Ethereum proof-of-stake chain and will not recognize or support any PoW forks.
Q: Can Aave censor transactions?
A: While the front-end may block certain addresses for compliance reasons, the core smart contracts are immutable and permissionless. Changes require full DAO approval.
Q: What happens to my assets if there’s an Ethereum fork?
A: On centralized exchanges like Binance or Coinbase, users may receive forked tokens based on pre-Merge snapshots. In DeFi, holding ETH in self-custody gives full control over both chains post-fork.
Q: Is the Merge happening in 2025?
A: While planning continues into 2025, the final timing depends on network conditions and validator coordination. Most estimates placed the Merge completion in late 2022; ongoing upgrades refine post-Merge functionality.
The Ethereum Merge represents more than a technical upgrade—it's a systemic shift requiring coordinated action across developers, protocols, and users. Aave’s proactive governance decisions highlight how DeFi can balance innovation with responsibility.
