Creating an account

In order to create a libra account, you would need to instantiate the LibraWallet as shown in the following code example:

// Create a new wallet
var wallet = new LibraWallet();

// Create a new account
var account = wallet.NewAccount();

// Mnemonic words (secret) for recovering wallet
var mnemonic = wallet.Mnemonic;
Console.WriteLine(mnemonic);

// Get your account address
Console.WriteLine(account.Address);

Recovering an account

In order to create a libra account, you would need to instantiate the LibraWallet as shown in the following code example:

// Recovering a wallet with mnemonic words (secret)
var mnemonic = "elite kidney kangaroo enhance list mule paddle arrange popular frown ahead carry endorse thunder toy broken absorb level surprise arrow analyst segment wave fat";

// Create a wallet
var wallet = new LibraWallet(mnemonic);

// Recover an Account
var account = wallet.NewAccount();

// Get your account address
Console.WriteLine(account.Address);

Minting an amount

To mint an amount, you would need to create a LibraClient and use it to mint

// Currently minting only works for testnet and uses the faucet service.
var client = new LibraClient(LibraNetwork.Testnet);

// Mint amout in Micro-Libra. (1 Libra = 1000000 Micro-Libra)
var sequenceNumber = await client.MintWithFaucetService(account.Address, 1000000);

Checking an address balance

// You can use parameter array for checking multiple addresses.
var accountState = await client.QueryBalance(account.Address);
Console.WriteLine(accountState.Balance);

Transferring Libra coins

// You can use parameter array for checking multiple addresses.
var sender = wallet.Accounts.ElementAt(0).Value;
var receiverAddress = "face4412ab3325cf6e26624cff089eb1bf8ec6da489f05aad72a81de5ff7b5d1";
var amount = 10000000UL;
var success = await client.TransferCoins(sender, receiverAddress, amount);
Console.WriteLine($"AC Status: {success}");
