 For each unique `key`, the sequence must be incremented by 1 for each transaction. This means that if you send multiple transactions in parallel, you can use different `keys` for the parallel transactions.
 
+### Parallel Transactions Ordering
+Important thing to note is that parallel transaction's ordering is not guaranteed. So execution of random `key` on chain could be:
+
+- [key-C][sequence-0]
+- [key-A][sequence-0]
+- [key-B][sequence-0]
+
+While execution of `sequence` for a specific `key` will always be in order. So the following is a valid order of execution:
+1. [key-C][sequence-0]
+2. [key-A][sequence-0]
+3. [key-C][sequence-1]
+4. [key-B][sequence-0]
+5. [key-A][sequence-1]
+6. [key-B][sequence-1]
