Ethereum’s London hard fork launched on the Ropsten testnet on June 24 in preparation for the mainnet rollout in July.
The upgrade will usher in the implementation of the highly anticipated EIP-1559 modification that will adjust the Ethereum transaction fee calculation mechanism.

The next phase in the London hard fork rollout is deployment on the Goerli testnet, which is scheduled for June 30. Following that, it will be launched on the Rinkeby testnet on July 7 and then mainnet later in the month.
