About

BitcoinCashClient makes it trivially easy to integrate native (non-custodial) Bitcoin Cash transactions into any C# .NET application with internet access.

This library provides a simple interface enabling on-chain sending and receiving of Bitcoin Cash by abstracting away as much complexity as possible. Wallet (private key and public address) creation, fetching wallet info from a block explorer, fetching up-to-date price data, managing utxos (hashes and indexes), inputs and outputs, network fee calculation, transaction signing, and broadcasting to the network are ALL handled by this library behind the scenes.

Private keys are never exposed. Don't trust. Verify.

How to Use

Instantiate

using BitcoinCash;

var client = new BitcoinCashClient();

Create new wallet

Generate a new Bitcoin Cash private key and its associated public address.

var wallet = client.GetWallet();

Get existing live wallet

Use a private key to get a live wallet. This operation retrieves all utxos, calculates the wallet balance (and fiat value), and enables sending funds.

var privateKey = "<your-private-key>";
var wallet = client.GetWallet(privateKey);

Note: Again, the private key is never exposed. The key is used to compute the public address, which is then used to fetch the wallet info from a block explorer.

Send

Send the specified amount of Bitcoin Cash to the specified address.

// send one dollar's worth of BCH to the destination address
wallet.Send("<destination-address>", 1m, Currency.USDollar);

Send All

Send the entire wallet balance to the specified address.

wallet.SendAll("<destination-address>");

Get existing read-only wallet

Use a public address to get a read-only wallet.

var publicAddress = "<any-valid-bch-address>";
var wallet = client.GetWalletByAddress(publicAddress);
