<h3>Handling Contract Objects</h3>
|

The variable <code>MyContractInstance</code> is a <code>web3.eth.Contract</code> object pointing to a deployed contract address. You can use a DApp framework like <a href="https://embark.status.im/docs/contracts_javascript.html" target="_blank" rel="noopener">Embark</a> to easily import that contract instance: <code>import { MyContract } from './embarkArtifacts/contracts';</code>, or use web3.js directly (just like in the example <a href="https://github.com/embarklabs/subspace/blob/master/examples/redux/src/MyContract.js#L36-L42" target="_blank">source code</a>)
