const soulboundIdentity: SoulboundIdentity = SoulboundIdentity__factory.connect(
  <address>, // address of the deployed contract

Generation of a new release

From a clean main branch you can run the release task bumping the version accordingly based on semantic versioning:

yarn release

The task does the following:

• Bumps the project version in package.json
• Creates a Git tag
• Commits and pushes everything
• Creates a GitHub release with commit messages as description
• Git tag push will trigger a GitHub Action workflow to do a npm release

For the GitHub releases steps a GitHub personal access token, exported as GITHUB_TOKEN is required. You can add this environment variable to the .env file. Setup
