HelloWorld-IconBlockchain

My first project on the IconBlockchain

How to use

1. Clone the repo
2. Deploy the hello_world_score (e.g. to your local testnet)
3. Update the keystore_test1 to match your credentials
4. Execute TestMain and don't forget to update the score address

Example Output

= All Score functions =================================================================================

hello
increment
