address := "myaddress"
timestamp := time.Now().Unix()
sum := sha256.Sum256([]byte(fmt.Sprintf("%s%d", address, timestamp)))
id := fmt.Sprintf("0x%x", sum)
```

## JaveScript

```javascript
const { createHash } = require('crypto');

const address = "myaddress"
const timestamp = Date.now()
const content = address + timestamp
const id = "0x" + createHash('sha256').update(content).digest('hex');
```
