Quick start for TVM SDK

Prerequisites

This demo app implements the following logic:

  1. Creates and initialize an instance of the SDK client;

  2. Creates a giver contract instance (will be used for send tokens to helloWorld contract);

  3. Deploys the helloWorld contract:

    3.1 Generates key pair for the contract;

    3.2 Calculate future address of the contract;

    3.3 Sends to the future address of the contract some tokens required for deploy;

    3.4 Returns instance of the helloWorld contract;

  4. Calls some methods (getter and setter) of the contract.

Important

After you have created and deployed the wallet and helloWorld contracts, you should to place their ABI files in the resources folder.

CONTRACT_CODE=PATH_TO_HELLOWORLD_CONTRACT_CODE    # helloWorld.tvc
GIVER_ADDRESS=YOUR_WALLET_ADDRESS
GIVER_KEYS=PATH_TO_YOUR_WALLET_KEYS_FILE

Run it

cargo run

You will see a result similar to the following:
