Each network has mainnet and testnet variants. Network objects configure transaction parsing and building behavior for specific cryptocurrencies.

```javascript
// Network | Mainnet | Testnet
// Bitcoin | utxolib.networks.bitcoin | utxolib.networks.testnet
// Bitcoin Cash | utxolib.networks.bitcoincash | utxolib.networks.bitcoincashTestnet
// Bitcoin Gold | utxolib.networks.bitcoingold | utxolib.networks.bitcoingoldTestnet
// Bitcoin SV (Satoshi Vision) | utxolib.networks.bitcoinsv | utxolib.networks.bitcoinsvTestnet
// Dash | utxolib.networks.dash | utxolib.networks.dash
// eCash | utxolib.networks.ecash | utxolib.networks.ecashTestnet

### Creating UTXO Transactions with @bitgo/utxo-lib

Source: https://www.npmjs.com/package/@bitgo/utxo-lib/package/%40bitgo/utxo-lib_activetab=versions

Use bitgo methods to create transactions from buffers, hex strings, or builders based on network configurations. Interfaces match bitcoinjs-lib Transaction type. Supports altcoins like Bitcoin Cash and Litecoin; inputs are buffers/strings/transactions, outputs are UtxoTransaction or UtxoTransactionBuilder objects.

```javascript
utxolib.bitgo.createTransactionFromBuffer(buffer, network): UtxoTransaction
// (similarly `createTransactionFromHex(string, network)`)

utxolib.bitgo.createTransactionBuilderForNetwork(network): UtxoTransactionBuilder

utxolib.bitgo.createTransactionBuilderFromTransaction(tx): UtxoTransactionBuilder
```

--------------------------------

### Create and Build Bitcoin Transactions

Source: https://www.npmjs.com/package/@bitgo/utxo-lib/package/%40bitgo/utxo-lib_activetab=readme

Create transactions from buffer or hex format, and build new transactions using the transaction builder. The UtxoTransaction and UtxoTransactionBuilder classes provide the same interface as bitcoinjs-lib's Transaction type. Returns UtxoTransaction objects and UtxoTransactionBuilder instances for multi-coin support.

```JavaScript
utxolib.bitgo.createTransactionFromBuffer(buffer, network): UtxoTransaction
```

```JavaScript
utxolib.bitgo.createTransactionFromHex(string, network): UtxoTransaction
```

```JavaScript
utxolib.bitgo.createTransactionBuilderForNetwork(network): UtxoTransactionBuilder
```

```JavaScript
utxolib.bitgo.createTransactionBuilderFromTransaction(tx): UtxoTransactionBuilder
```
