<code>hash</code> is the script hash of the contract. It is encoded as a hexadecimal string in big-endian.

<code>entryPoint</code> is a Method object which describe the details of the entrypoint of the contract.

<code>methods</code> is an array of Method objects which describe the details of each method in the contract.

<code>events</code> is an array of Event objects which describe the details of each event in the contract.

===EntryPoint===

It is strongly recommended that each contract have the following entry point:

<pre>
{
"name": "main",
"parameters": [
{
"name": "operation",
"type": "String"
},
{
"name": "args",
"type": "Array"
}
],
"returntype": "Any"
}
</pre>

In this way, the caller can easily access the methods through the entry point, specifying the name of the method to be invoked with the first parameter, and specifying the parameters of the method with the second parameter.
