The Merge | ethereum.org

Ethereum Merge is the most significant upgrade in the history of Ethereum.

As Mainnet gets merged with the Beacon Chain, it will also merge the entire transactional history of Ethereum.

Any funds held in your wallet before The Merge will still be accessible after The Merge.

The Merge has been designed to have minimal impact on smart contract and dapp developers, but there are a few small things devs may want to be aware of heading into The Merge.

Not before The Merge, not after The Merge, not ever.
