Impact on testnets

Goerli

Available

Goerli is a proof-of-stake testnet, and is the recommended default testnet for testing of staking and validating.

Sepolia

Available

Sepolia is a proof-of-stake testnet, and is the recommended default testnet for application development.

Ropsten

Decommissioning Q1 '23

Official Ropsten support has been deprecated by the Ethereum Foundation. QuickNode will be decommissioning support for Ropsten in Q1 '23. Please move your testing to Goerli or Sepolia.

Kovan

Decommissioning Q1 '23

Official Kovan support has been deprecated by the Ethereum Foundation. QuickNode will be decommissioning support for Kovan in Q1 '23. Please move your testing to Goerli or Sepolia.

Rinkeby

Decommissioning Q2 '23

Official Rinkeby support will be deprecated by the Ethereum Foundation. QuickNode will be decommissioning support for Rinkeby in Q2 '23. Please move your testing to Goerli or Sepolia.

What is The Merge?

The Merge is the transition of Ethereum from Proof of Work (PoW) to Proof of Stake (PoS).

The transition to POS will remove the need for energy-intensive mining process while also securing the network using staked ETH. This transition will lay the foundation for better security, scalability, and sustainability.

For more detail, you can go to the Ethereum Foundation.

How is QuickNode handling The Merge?

Methods

We added support for Ethereum Mainnet Beacon REST APIs. You can already see the methods available in our docs, they start with eth/.

Read docs

Testnets

We have outlined the impacts to testnets above, where we will continue to support Goerli and Sepolia in the long term. We are decommissioning support for Ropsten and Kovan in Q1 '23 and Rinkeby in Q2 '23.

Client

We are using Lighthouse as our client. In our internal testing, we found that Lighthouse provided the most consistent REST API performance across a wide variety of methods. In case of failure, we have Teku as a backup. We will continue to run Geth, Nethermind, Erigon nodes.

Frequently Asked
Questions

Still have unanswered questions? Please reach out to support and we can help you find answers.

How should I prepare for The Merge?

Goerli and Sepolia testnets are the best long-term testnets for Ethereum. We are decommissioning support for Ropsten and Kovan in Q1 '23 and Rinkeby in Q2 '23.

When is The Merge happening?

The Merge was successful on September 15th.

How will this affect the JSON-RPC responses from QuickNode?

The Merge will happen between blocks and all current JSON-RPC methods will behave in nearly identical ways, with only slight modifications to the parameters returned.

If you would like to know more about these changes, we recommend reading the official Ethereum Foundation blog post here: https://blog.ethereum.org/2021/11/29/how-the-merge-impacts-app-layer/.

Will there be new methods after The Merge?

We added support for Ethereum Mainnet Beacon APIs. You can already see the methods available in our docs, they start with eth/.Read docs

What testnet should I move to?

Goerli and Sepolia testnets are the best long-term testnets for Ethereum.

What testnets will be decommissioned?

We will stop supporting Ropsten and Kovan in Q1 '23 and Rinkeby in Q2 '23. Please move your testing to Goerli or Sepolia.

What clients are you using?

We are using Lighthouse as our client. In our internal testing, we found that Lighthouse provided the most consistent REST API performance across a wide variety of methods. In case of failure, we have Teku as a backup.
