Breadcrumb

Breadcrumb takes away the complexity that you normally encounter when working with other Bitcoin, or Blockchain libraries.

With minimalistic interfaces you can quickly get started working with Bitcoin, and the Blockchain.

Explore the capabilities of the block chain by publishing, and building custom transactions, and scripts.

Making a wallet is so easy you can start sending, and receiving Bitcoin in less than 15 lines of code.

How to get started

Include Breadcrumb.framework, and CommonCrypto.framework into your Xcode project.

Add #import <Breadcrumb/Breadcrumb.h> to one of your applications' source files.

Make a wallet, and start sending Bitcoin.

  NSData *password = [@"password" dataUsingEncoding:NSUTF8StringEncoding];
  BCWallet *wallet = [[BCWallet alloc] initNewWithPassword:password];

  [wallet mnemonicPhraseWithPassword:password
                       usingCallback:^(NSString *mnemonic) { 
    NSLog(@"Brainwallet Phrase: %@",mnemonic);
  }];

  BCAddress *address = [@"3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy" toBitcoinAddress];
  NSNumber *amount = @20000; // Satoshi
  [wallet send:amount to:address usingPassword:password withCallback:
  ^(NSError *error) { 
       if ( [error isKindOfClass:[NSError class]] )
            NSLog(@"Transaction Failed: '%@'",error.localizedDescription); 
  }];
