The Ethereum mainnet's transition to Proof-of-Stake (PoS) consensus continues to prompt updates from DeFi protocols and exchanges preparing for potential disruptions. Aave has joined this wave with a proposal to temporarily halt ETH lending services before the Merge.
Temporary Suspension of ETH Borrowing
Aave's risk analysis team, Block Analitica, recommended pausing ETH borrowing to prevent catastrophic events that could impact the broader decentralized finance (DeFi) ecosystem. Key concerns include:
High ETH utilization rates potentially triggering:
- Difficult or impossible liquidations
- Negative APY for stETH/ETH positions
- Mass ETH withdrawals by suppliers
Proposed mitigation measures include:
- Implementing a 1,000% variable borrow APR at 100% utilization
- Adjusting interest rate curves to 103% post-"kink" (vs. 1,000%)
Gauntlet Network suggested splitting the proposal into two parts, with voting open until September 2nd.

Ethereum PoS as the Canonical Chain
Aave recently affirmed its commitment to Ethereum's PoS chain via an Aave Request for Comment (ARC), stating:
- No support for alternative consensus forks (e.g., Proof-of-Work)
- Aave V3 already tested on merged Ropsten/Goerli testnets
- Community guardians authorized to shut down non-PoS fork deployments
This protects Aave's TVL by preventing protocol fragmentation across chains.
Exchange Updates on the Merge
Binance and Coinbase Preparations
- Deposit/withdrawal pauses scheduled September 6-15 during upgrades
- Support for potential fork tokens (subject to listing reviews)
- ETH futures and auto-invest products remain active
Fork Token Policies
Exchanges will:
- Snapshot ETH balances pre-Merge
- Credit forked tokens (e.g., ETHPoW) if chains split
- Evaluate fork tokens using standard listing criteria

Aave's Approach to Chain Censorship
Following Tornado Cash sanctions:
- Front-end blocks implemented via TRM Labs API
- Smart contract changes require DAO approval
- Founder Stani Kulechov emphasized protocol immutability without validator consensus
FAQ Section
Q: Why pause ETH borrowing before the Merge?
A: To prevent liquidation failures and negative yields from extreme utilization rates.
Q: Will Aave support Ethereum forks?
A: No—only the canonical PoS chain will receive official support.
Q: How long will ETH withdrawals be paused?
A: Most exchanges anticipate 1-2 weeks around the Merge dates (September 6-15).
Q: Can Aave's smart contracts be censored?
A: Only front-end access can be restricted without DAO-approved contract changes.
Q: What happens to my ETH during the Merge?
A: Holders retain assets on both chains if a fork occurs, but only PoS ETH has exchange support.
