Deploy-a-Smart-Contract.md

To deploy a Smart Contract, you'll either need to make a Steem post, post a custom_json operation or transfer funds with a memo on Steem (this will depend on how big the code of your contract is), for all the different solutions you'll need to send a JSON like this:

{
    "contractName": "contract",
    "contractAction": "deploy",
    "contractPayload": {
        "name": "MySmartContractName",
        "code": "BASE64EncodedJavascriptCode"
    }
}

• name: this is the name of the Smart Contract you want to deploy, it has to be unique on the sidechain
• code: this is the code of your Smart Contract, it is basically your Javascript code encoded on Base64 (you can easily encode your code via this tool: https://www.base64encode.org/)
