 # stellar-extended-merge
-Fully merges a stellar account, copying all custom assets and offers
+The Stellar network account merge function will fail if the source account has sub entries; i.e custom assets or offers.
+This app fully merges a stellar account, copying all custom assets and offers.
+
+#How it works
+Here is a brief algorithm
+- Check if source account has custom assets/pending offers(sub-entries)
+- If custom assets
+  - for each asset:
+    - create trustlines for the assets on the destination account
+    - transfer funds to destination account
+    - remove trustlines from source account
+- If offers
+  - create matching offer on destination account
+  - delete offers on source account
+- call regular merge funtion
+
+#Notes
+- The transaction fee will be higher because of all the extra operations carried out before the merge
+- The secret seed of the destination account is required for this to work
+- All operations are grouped into one transaction so if any operation fails the whole merge fails
