To deploy a smart contract using a tronbox, you need to write a smart contract file, compile the smart contract, and finally migrate and deploy the smart contract. After that you can then use the script to test.

## Smart Contract Development

All smart contract files need to be placed in the `./contracts` directory. By default, there will be a contract file with a suffix of `.sol`. But if you need to write a smart contract, you need to create a new `.sol`. Tronbox requires the smart contract name to be the same as the file name. For example, if the file name is `Test.sol`, we can write the contract as follows:

## Configuring migration scripts

Configuring migrations/2_deploy_contracts.js as follows:

The deploy function in this file also supports the contract constructor arguments.

## Configuring compilation and deployment parameters

The tronbox.js file holds configurations the contract will deploy to. To specify the network, use --network _NETWORK_NAME_ when migrating or testing.

Solidity Support To set up a specific compiler version, use the typical Truffle approach in tronbox.js, using the `networks.compilers.solc.version` property. For example:

Solidity compiler versions supported by TronBox:

  • <a href="" target="_blank">**0.4.24**</a>

  • <a href="" target="_blank">**0.4.25**</a>

  • <a href="" target="_blank">**0.5.4**</a>

  • <a href="" target="_blank">**0.5.8**</a>

## Compiling smart contract

To compile the contract, use:

By default, tronbox compiler only compiles modified contracts since last compile, to reduce unnecessary compiling. If you wish to compile the entire file, you can use `--compile-all`.

The compile output is in `./build/contracts` directory. If the directory doesn't exist, it will be auto-generated.

## Contract Deployment

Script migration is with a JavaScript file composed to broadcast onto Tron network. The script migration caches your broadcast responsibility. Its existence is based on your broadcast needs and will adjust accordingly. When your work incurs significant change, the migration script you created will propagate the changes through the blockchain. Previous migration history records will undergo a unique `Migrations` contract to be recorded on the blockchain. Below is a detailed instruction.

To initiate the migration, use the following command:

This command will initiate all migration scripts within the `migration` directory. If your previous migration was successful, `tronbox migrate` will initiate a new migration and use the `development` network by default.

If there is no new migration script, this command will have no operation. Instead, you can use --reset to re-deploy. You can also use --network _NETWORK_NAME_ to specify a network. Eg. `tronbox migrate --reset --network production`

## Trigger Contract

The testing scripts are in the `./tests` directory. TronBox will ignore all other extensions except for .js, .es, .es6, and .jsx Below is an example testing script for test.js:
