Update on the Ethereum Merge

As previously communicated, Ethereum's main network will be transitioning from Proof of Work to Proof of Stake soon. To prepare for this event, Zero Hash successfully migrated our CERT environment to the Goerli test network which is the officially supported testnet due to the prior Ropsten testnet being deprecated.

The mainnet merge is expected to happen September 15th at approximately 05:00 - 06:00 UTC.
Here are a few 3rd party links that are tracking the timing to the merge (note that these services are not affiliated with Zero Hash):

Zero Hash has opened a maintenance window for our Production environment (CERT will remain operational) 30 minutes prior to the merge and closing approximately 2-4 hours after. The exact timing of the window will fluctuate depending on network factors leading up to the merge event.

As a precaution, Ethereum and EVM related assets will be available for trading but deposits and withdrawals will be queued until the maintenance window is completed. It is recommended that platforms refrain from submitting deposits and withdrawals until after the maintenance window is completed. Any withdrawals submitted during this window will be queued and processed automatically once blockchain activity resumes.

For Zero Hash Liquidity Services, there may be some instability from our liquidity providers although they have communicated pricing shall be continuous through the maintenance period.

Production assets restricted from trading during the maintenance window:

• Ether
• All ERC20 tokens (USDC, Chainlink, Wrapped ETH, ApeCoin, etc)
• All ETH level 2 chains and side-chains
  • Arbitrum
  • Optimism
  • Polygon

Note that any production deposit addresses, wallets, asset symbols, and API functionality are not changing and will remain the same post-merge. This update only impacts Zero Hash's production environment.

Please reach out to your Zero Hash team with any questions or concerns.
