Manage Contract

Deploy a compiled contract to a network, or update one in place. On Neo N3 an update keeps the same script hash — it is not a redeploy. Both actions build, sign and broadcast a transaction with your active wallet account, so that account needs some GAS.

Usage

From the home screen choose Manage Contract, then pick Deploy or Update.

Deploy

  1. Network: switch between TestNet and MainNet (or a custom RPC).
  2. Contract files: click Select .nef and pick your compiled .nef. The matching .manifest.json next to it is detected automatically; use Select manifest if it lives elsewhere.
  3. Click Deploy and enter your account password when prompted.
  4. On success you get the new contract hash and the transaction id.

Update

  1. Network: choose the network the contract lives on.
  2. Contract hash: paste the deployed contract's script hash (0x...).
  3. Contract files: select the new .nef (and manifest) the same way as for deploy.
  4. Click Update and enter your account password when prompted.

The target contract must expose an update method. The script hash is unchanged after a successful update.
