Account observer:
```javascript
import { web3 } from '@hicaru/bearby.js';

/// To avoid memory leak don't forget unsubscribe!!!
observer.unsubscribe();
```

import { web3 } from '@hicaru/bearby.js';

/// Emit everytime when network been changed.
const observer = web3.wallet.network.subscribe((net) => console.log(net))

/// To avoid memory leak don't forget unsubscribe!!!
observer.unsubscribe();
```

  emitter_address: null,
};
const response = await web3.contract.getFilteredSCOutputEvent(eventsFilter);

if (response && response.result && response.result[0] && response.result[0].data) {
  const contract = String(response.result[0].data).replace('Address:', '');
