 ## Abstract
 
-A standard format for transferring a key's signing history allows validators to easily switch between clients without the risk of signing conflicting messages. While a [common keystore format](https://eips.ethereum.org/EIPS/eip-2335) provides part of the solution, it does not contain any information about a key's signing history. For a validator moving their keys from client A to client B, this could lead to scenarios in which client B inadvertently signs a message that conflicts with an earlier message signed with client A. The interchange format described here provides a solution to this problem.
