Issues three university diplomas on-chain using the UVerify diploma template. All certificates are submitted in a single Cardano transaction.

• Python 3.9+
• uv

# macOS / Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

uv run main.py

uv reads the dependency list embedded at the top of the script and installs everything automatically. No virtual environment setup or pip install required.

On first run a new wallet is generated, funded from the UVerify testnet faucet, and the mnemonic is saved to wallet.txt. Subsequent runs restore the same wallet.

Keep wallet.txt private — it holds your private key phrase.

1. Creates or restores a wallet from wallet.txt.
2. Issues diplomas for three fictitious TU Munich graduates via client.apps.issue_diploma().
3. Waits for on-chain confirmation and prints a verification URL for each diploma.

Targets the Cardano preprod testnet. Verification links open at https://app.preprod.uverify.io/verify/….
