Running the Program

Leo provides users with a command line interface for compiling and running Leo programs. Users may either specify input values via the command line or provide an input file in inputs/.

Configuring Accounts

The program.json/.env file contains a private key and address. This is the account that will be used to sign transactions and is checked for record ownership. When executing programs as different parties, be sure to set the private_key and address fields in program.json to the appropriate values.

See ./run.sh for an example of how to run the program as different parties.

The Aleo SDK provides a command line interface for generating new accounts. To generate a new account, run

leo account new

Using an input file.

1. Modify inputs/shib.in with the desired inputs.
2. Run

leo run <function_name>

For example,

leo run issue
leo run monopoly_buy
leo run monopoly_rent
leo run monopoly_sale
leo run mystery_card
leo run mint_reward => test
