How to run examples (script mode as default) + +All examples are expected to be run **from `examples/from_go`**. + +#### 2-1. Run as scripts (recommended) + +```bash +cd toolbox/py-wallet-toolbox/examples/from_go +source .venv/bin/activate + +# Example: create a data transaction (OP_RETURN) +python wallet_examples/create_data_tx/create_data_tx.py + +# Example: check wallet balance +python wallet_examples/get_balance/get_balance.py + +# Example: show faucet receive address +python wallet_examples/show_address_for_tx_from_faucet/show_address_for_tx_from_faucet.py +``` + +> Note: You can also run them as modules, e.g. `python -m wallet_examples.create_data_tx`, +> but for day-to-day usage the simple β€œrun the script file” pattern above is usually enough. + +Every script uses `from internal import setup, show` to share common setup and logging helpers from `internal/`. + +--- + +### 3. Recommended execution order (scenario-based) + +There are many samples under `wallet_examples/`. +If you want a guided path, **start with the following order**: + +> Assumption: You have already done +> `cd toolbox/py-wallet-toolbox/examples/from_go` and activated `.venv`. + +#### 3-1. Get test funds from a faucet + +1. **Show faucet address** + + ```bash + python wallet_examples/show_address_for_tx_from_faucet/show_address_for_tx_from_faucet.py + ``` + + - Copy the address printed to the console. + - Use a testnet faucet (e.g. a public web faucet for BSV testnet) to **manually send** coins to that address. + +2. **Internalize the faucet transaction into the wallet** + + ```bash + python wallet_examples/internalize_tx_from_faucet/internalize_tx_from_faucet.py + ``` + + - Before running, edit the script and set `TX_ID` at the top to the transaction ID of the faucet payment + (as seen in your block explorer). + +#### 3-2. Inspect balance and UTXOs + +3. **Check balance** + + ```bash + python wallet_examples/get_balance/get_balance.py + ``` + +4. **List UTXOs (outputs)** + + ```bash + python wallet_examples/list_outputs/list_outputs.py + ``` + +5. **Inspect action history** + + ```bash + python wallet_examples/list_actions/list_actions.py + python wallet_examples/list_failed_actions/list_failed_actions.py + ``` + +#### 3-3. Create and broadcast transactions + +6. **Create a data transaction (OP_RETURN)** + + ```bash + python wallet_examples/create_data_tx/create_data_tx.py + ``` + + - This requires that the wallet already has funds (from the faucet step). + - You can change `DATA_TO_EMBED` in the script to embed arbitrary text. + +7. **Create a P2PKH payment** + + ```bash + # Edit the script first: set RECIPIENT_ADDRESS and SATOSHIS_TO_SEND + python wallet_examples/create_p2pkh_tx/create_p2pkh_tx.py + ``` + + - Set `RECIPIENT_ADDRESS` to the destination address and `SATOSHIS_TO_SEND` to the amount you want to send. + +#### 3-4. Encryption / decryption samples + +8. **Encrypt / Decrypt** + + ```bash + # Encryption sample + python wallet_examples/encrypt/encrypt.py + + # Decryption sample + # -> First, take the ciphertext produced by the encrypt example + # and paste it into the CIPHERTEXT variable in decrypt.py + python wallet_examples/decrypt/decrypt.py + ``` + +#### 3-5. Advanced samples (optional) + +9. **Internalize a wallet payment (BRC-29 style)** + + ```bash + # Fill in ATOMIC_BEEF_HEX / PREFIX / SUFFIX / IDENTITY_KEY + # according to your actual BRC-29 payment flow before running + python wallet_examples/internalize_wallet_payment/internalize_wallet_payment.py + ``` + +10. **Batch send using NoSend + SendWith** + + ```bash + python wallet_examples/no_send_send_with/no_send_send_with.py + ``` + + - This demonstrates creating multiple transactions with the `noSend` option + and then broadcasting them together with `sendWith`. + -
