### Build Cardano Testnet Address

Source: https://docs.cardano.org/cardano-testnets/getting-started

Constructs a Cardano payment address using the generated payment and stake verification keys. The `--testnet-magic INTEGER` flag specifies the testnet network (e.g., 2 for Preview, 1 for Pre-production).

```bash
cardano-cli address build \
--payment-verification-key-file payment.vkey \
--stake-verification-key-file stake.vkey \
--out-file payment.addr \
--testnet-magic INTEGER  

```

### Query Cardano Testnet Address Balance

Source: https://docs.cardano.org/cardano-testnets/getting-started

Queries the Unspent Transaction Output (UTXO) balance of a given Cardano testnet address. It requires the address to be provided, typically by reading from a file, and the testnet magic integer.

```bash
cardano-cli query utxo \
--address $(cat payment.addr) \
--testnet-magic INTEGER  

```

### Generate Cardano Payment Keys

Source: https://docs.cardano.org/cardano-testnets/getting-started

Generates a pair of payment keys (verification and signing) required for sending and receiving transactions on Cardano testnets. This process creates two files: payment.vkey (public key) and payment.skey (private key).

```bash
cardano-cli address key-gen \
--verification-key-file payment.vkey \
--signing-key-file payment.skey  

```
