### Notice

* if `pre` > `max`, only `max` amount of tokens will allocate to `to` address.
* If `to` field is not configured,  it defaults to the transaction sender address.
* In "Issue Mode", Use the deployment transaction ID as the token contract address (CA).
* Use API to check whether the corresponding `tick` is available before deployment to avoid loss of transaction fee.
