Aave has halted ETH lending until the Merge has gone through, while 
Compound Finance has opted to cap the number of loans and introduce a 
“jump” interest rate model. 
The growing number of speculators taking out Ether (ETH) loans to 
maximize their potential to earn forked Ether Proof-of-Work tokens 
(ETHPoW) has been causing headaches for decentralized finance protocols.
 
The issue has been gaining traction over the past month or so, 
given that a significant number of Ether miners are expected to continue
 working on a forked PoW chain, or possibly even multiple chains post the long awaited Merge. 
In
 the event of a fork, on-chain ETH hodlers such as those using 
non-custodial wallets or those holding on exchanges that are supporting 
ETHPoW will be airdropped the equivalent amounts of the new tokens to 
their ETH holdings. 
This is because your ETH balance on the existing chain will be duplicated on the forked PoW chain.
On Sept. 6, the Aave governance community overwhelmingly voted in favor of halting ETH lending “in the interim period leading up to the Merge.”
This
 proposal was initially put forward on Aug. 24 as result of the demand 
for Aave ETH loans surging to levels that were starting to put pressure 
on the liquidity supply. 
Aave has a complex structure for issuing
 interest rates, and utilizes algorithms to determine percentages taking
 into account the liquidity and demand for borrowing on the platform. 
“Once
 the ETH borrow rate reaches 5%, which happens shortly after 70% 
utilization rate (we are at 63% right now), stETH/ETH positions start 
becoming unprofitable,” the proposal stated as of Aug. 24. 
It was
 added that if these positions do start to become unprofitable, users 
would likely race to “unwind their positions up until the ETH borrow 
rate reverts to a stable level where the APY [Annual Percentage Yield] 
becomes tolerable.” As such, this would put even more pressure on 
liquidity supply of ETH on Aave. 
The vote yesterday polled 77.87%
 in favor (528,290 people) and 22.13% against (150,170 people), and the 
proposal was executed on the same day. 
Earlier this week another 
DeFi lender Compound Finance also had a forked Ethereum risk 
mitigation-related proposal that was voted through, and notably had zero votes in opposition to the 347,559 in favor. 
Compound’s
 idea, which went live as of Sept. 5, was to set the borrow cap at 
100,000 ETH until the dust from the Merge has settled. 
Additionally
 the protocol updated its interest model to a “jump rate model with much
 higher rates after exceeding 80% borrow utilization” which bumps to a 
maximum rate of 1000% APR if 100% utilization is reached. 
The hope is that this will deter users from overwhelming Compound with borrowing and withdrawals from the platform.
Proposal 122 prepares for the Merge and a potential POW fork by protecting cETH user liquidity.
— Compound Labs (@compoundfinance) September 2, 2022
It imposes a borrowing cap of 100,000 ETH, and introduces a new interest model with very high upper bounds.

ETH outflows on exchanges
Users
 are certainly positioning themselves to get free tokens,despite 
numerous stablecoins and projects distancing themselves from a PoW 
chain. 
Delphi Digital’s latest report notes that despite 
declining price of ETH of late, exchanges saw outflows totaling 476,000 
on Aug. 29. 
This marks the third largest amount of ETH 
withdrawals since March, and the firm attributed this to Merge and 
investors repositioning to collect ETHPoW tokens:
“To
collect the most amount of ETHPoW tokens, users are likely withdrawing
ETH balances from centralized exchanges to non-custodial wallets,
leading to an increase in the net outflow of ETH from exchanges.”
While
 it is unclear if the forked chains will attract strong enough interest 
to develop a lasting ecosystem and community, in the short term crypto 
degens at least seem keen to gobble up free forked tokens.
