Changes to ETH and ERC-20 tokens during the Ethereum Merge

Changes to ETH and ERC-20 tokens during the Ethereum Merge

On Thursday September 15 at around 2:30 pm (AEST), Ethereum will undergo its highly anticipated transition from Proof-of-Work to Proof-of-Stake.

Known as the Merge, the switch will cause a hard fork in the Ethereum chain and may result in temporary outages for both ETH and ERC-20 tokens.

Here’s what you need to know about your CoinJar and the Merge.

Withdrawals, deposits and trading

Withdrawals for all ETH and ERC-20 tokens will be paused for a brief period either side of the Merge event. We will let you know when withdrawals have resumed on our Status page.

You will still be able to make deposits, although they may be delayed. Trading will be unaffected.

When exactly will the Merge happen?

The Merge is scheduled to occur when the total network difficulty reaches a certain level. The best estimate for when this will happen is September 15 at 2:35 pm (AEST), but it could commence anywhere within a three hour window around that time.

Do I have to do anything?

No. All your ETH and ERC-20 tokens will continue on in the same amounts with the same addresses after the Merge.

Be vigilant: anyone telling you that you have to take action to upgrade your tokens or move them to the new chain is trying to scam you.

Will I receive tokens on the ETHPOW chain?

After the Merge, there is a chance that the old Ethereum Proof-of-Work chain will continue operating, meaning two sets of Ethereum tokens will now be in existence – ETH and ETHPOW.

CoinJar is fully committed to the Merge and will not be supporting ETHPOW at this time. Any ETH and ERC-20 tokens sent to your CoinJar account on the ETHPOW chain will be lost permanently.

It is highly unlikely that ERC-20 tokens and stablecoins on the ETHPOW chain will have any value after the Merge, so always make sure you are buying or trading tokens on the new ETH mainnet.
