 When the `isOperationReady` method is called, the endorser must return this information:
 
 * **readiness:** when returning`true`, it means the transaction WILL be executed correctly and the bundler WILL be paid the offered gas fees (even if the underlying intent of the operation fails).
+* **blockDependency:** maximum values for block values; once the block reaches these values, the `readiness` result MUST be re-evaluated.
 * **dependencies:** a comprehensive list of addresses and storage slots that must be monitored; any state change in these dependencies MUST trigger a re-evaluation of the operation's readiness.
 
 The information provided by the endorser helps the mempool operator maintain a pool of "good" AA transactions that behave correctly; it DOES NOT guarantee that such transactions will be able to be executed correctly. Bundlers must always simulate the result of the execution before including a transaction in a block. They can alternatively monitor the dependencies for changes induced by other transactions in the mempool.
