Access to pre-regenesis history
Because of our final regenesis on 11 November 2021, older transactions are not part of the current blockchain and do not appear on Etherscan.
However, you can access transaction history between 23 June 2021 and the final regenesis using a number of different tools. For detailed instructions, see Regenesis History.
