+# Bump Footprint Expiration
+The `BumpFootprintExpirationOp` operation is used to extend a contract data entry's lifetime.
+
+A contract instance, wasm hash, and data storage entry (persistent/instance/temporary) can expire, so you can use this bump operation to extend its lifetime.
+Read more about it:
+- https://soroban.stellar.org/docs/fundamentals-and-concepts/state-expiration#bumpfootprintexpirationop
+- https://docs.rs/soroban-sdk/latest/soroban_sdk/storage/struct.Storage.html
+
+In this example, we will bump the contract instance of an already deployed contract in the network, adding 1000 ledgers to it.
+
+> **Warning**
+> Please note that Soroban is still under development, so breaking changes may occur.
+
+> **Note**
+> All this actions require to use `simulateTransaction` and `sendTransaction` RPC endpoints when specified in the code comments to achieve the bump footprint expiration.
