SPV bitcoin C library

breadwallet

bitcoin done right

The simplest and most secure bitcoin wallet on any platform

The first standalone iOS bitcoin wallet:

Unlike other iOS bitcoin wallets, breadwallet is a real standalone bitcoin client. There is no server to get hacked or go down, so you can always access your money. Using SPV mode, breadwallet connects directly to the bitcoin network with the fast performance you need on a mobile device.

The next step in wallet security:

breadwallet is designed to protect you from malware, browser security holes, even physical theft. With AES hardware encryption, app sandboxing, keychain and code signatures, breadwallet represents a significant security advance over web and desktop wallets, and other mobile platforms.

Beautiful simplicity:

Simplicity is breadwallet's core design principle. A simple backup phrase is all you need to restore your wallet on another device if yours is ever lost or broken. Because breadwallet is deterministic, your balance and transaction history can be recovered from just your backup phrase.

Features:

• "Simplified payment verification" for fast mobile performance
• No server to get hacked or go down
• Single backup phrase that works forever
• Private keys never leave your device
• Import password protected paper wallets
• "Payment protocol" payee identity certification

Translations managed by:

PhraseApp - Start localizing software the simple way

URL scheme:

breadwallet supports the x-callback-url specification with the following URLs:

bread://x-callback-url/address?x-success=myscheme://myaction

This will callback with the current wallet receive address: myscheme://myaction?address=1XXXX

The following will ask the user to authorize copying a list of their wallet addresses to the clipboard before calling back:

bread://x-callback-url/addresslist?x-success=myscheme://myaction

WARNING:

Installation on jailbroken devices is strongly discouraged.

Any jailbreak app can grant itself access to every other app's keychain data and rob you by self-signing as described here and including <key>application-identifier</key><string>*</string> in its .entitlements file.

breadwallet-core's Issues

A serious logic error that frees BRPeer twice in BRPeerManagerConnect

This error will cause app crash

I will give some illustations to show it.

Step 1

In BRPeerManagerConnect, we do BRPeerConnect

Step 2

We assume that everything is ok in BRPeerConnect. Then, we will go into _peerThreadRoutine

Step 3

In _peerThreadRoutine we run to 1090 line. Here we assume we got the lock, then we run to 1091 line. OK, let's look back at BRPeerManagerConnect. Which line does it run ? Go to Step 4

Step 4

In BRPeerManagerConnect, we now at BRPeerConnectStatus. Let's look at BRPeerConnectStatus.

Step 5

When we want to get BRPeer status, we firstly need to get the peer's lock. You know, currently, the lock has been got in _peerThreadRoutine which at 1090 line. On the other hand, in _peerThreadRoutine we run at 1091 line. So BRPeerConnectStatus will be blocked until get the lock.

Step 6

OK, it's time for _peerThreadRoutine releasing the lock. BRPeerConnectStatus returns the BRPeerStatusDisconnected. Then we get into a situation that _peerDisconnected will be called. Switch to Step 7 to see what does it do.

Step 7

Ignore others, just look at BRPeerFree(peer); that frees BRPeer.

Step 8

Finally, let's switch back to _peerThreadRoutine. At line 1109, disconnected which is _peerDisconnected will be called again. So everyone will know its result(crash).

Solution

Actually, we can use another Status to make a difference from BRPeerStatusDisconnected

BSV Fork

Hi I have written a fork of your code that supports BSV
Please shout if you want to get in contact
to see the changes; clone
https://github.com/edwardbr/breadwallet-core
and checkout the bsv branch
I have only spent about 5 hours on it so I am sure that there are some issues!
I am not interested in the Java and Swift tests, however I do not think I have broken anything, only the isBtc flag in your tests is now a tri state, btc 1, bch 0, bsv 2
I have also compiled for ubuntu fixing/suppressing a few warnings and compile errors

Master branch is still using `core-4.0.0-beta.2`

Master branch contains a sub-module pointing to core-4.0.0-beta.2 with hash: bb2024b

Could someone explain me why this sub-module was not updated from Dec 5, 2019?

Libraries for Android

Hi Guys -

I am working on forking this wallet for LTC and running into issues compiling the core. Is this the version that is also used for android, and if so, are there any instructions on how to compile in Android studio?

Also would you all be interested in porting this to LTC at all? Given all the recent developments into LTC, this may be great. I can lend a hand as much as possible. Currently the bitcoinj implementation is downright dangerous and your wallet is more of a public service to keep folks and their crypto safe!

p.s. I got the gradle build working, but the c libraries have issues with android studio.

Where is the source code for Breadwallet's Ethereum integration?

I see Ethereum in the latest IOS Breadwallet, but cannot find code for Ethereum in any of the common breadwallet repositories.

Where can I find it, or is this no longer an open source project?

Binance Smart Chain

I sent my ETH from Binance (Binance Smart Chain (BSC) BEP20 (BSC)) to BRD. I don't see my money in BDR!
TxID:
https://bscscan.com/tx/0xb6766a4466d4ab6fc130dc9f777aad72731430aea37968551ba7484eadc3b28c

I lost my 200$! I think that a lot of people lost they money too, because BRD does not support the Binance Smart Chain!

I hope you will add support the BSC soon! And I will take my money back!

How to compile

Hey I am a beginning c programmer and I can't compile this project.
I cloned this project and tried to compile the project with:" gcc test.c" but it had a lot of errors.
What am I doing wrong?

Thanks in advance
Daan

unable to add nodes

In the advanced settings I'm unable to add nodes by hand.
reason is because of locale the keypad only show a , for entering the ip instead of a .

Please send me money

Please send me money

The mnemonic does not match the address

When I create a new account, write down the papar key,then I import the mnemonic in eth website,the address is different with brd address.

$

Please change this string to "Bitcoin Cash"

breadwallet-core/Swift/BRCrypto/BRBitcash.swift

Line 15 in 8eb0545

public static let currency = Currency (code: "BCH", symbol: "₿", name: "Bitcash", decimals: 8,

"Bitcash" (BITC) is a completely different currency.

Testing Suite

Any pointers how to run test.c?

I got to the point that I'm able to compile on android using gradlew but then I'm not sure how to run test.c.

gradlew :app:externalNativeBuildBrdTestnetDebug

From there I copy my library from app/build/intermediates/cmake/brdTestnet/debug/obj

But when I'm using it on test.c it doesn't link property, I'm sure I'm missing something simple.

Bitpay Bitcoin invoices broken on IOS Breadwallet 3.0

I went to pay a Bitpay invoice with Bitcoin. Scanned the QR code, loaded the request, no issues. Tried to pay and it says "Invalid Bitcoin address".

App also doesn't embed the version into the about screen. This must be 3.0 according to the app store.

Cash Account Integration

I am currently working on a specification for on-chain aliases that look like this: James#577821; to help convey payment information in a more convenient manner, particulary in verbal contexts.

The specification has undergone reasonable peer-review so far (by wallet developers, token developers, coinbase engineeers) but more feedback is always welcome.

Here's a link to the draft spec: https://gitlab.com/cash-accounts/specification/blob/master/SPECIFICATION.md

SegWit

Will Breadwallet support and signal SegWit on its transactions?

MISSING BTC

Hello, i were using multibit hd and Breadwallet together. I used both of them with 1 wallet opened on both. Suddenly my pc broke and i tried to restore my wallet on new pc. When i restored one btc address with money on it was missing. i tried to generate private addresses from BIP39 mnemonic but i couldnt find that recieving addres in the list of 50000 address. Money is still unspent. Help me to get it back i know wallet words and everything. If someone helps me i will gift him/her a bunch of a beer on btc address :)
I reinstalled mac os everything is deleted. I know what was the wallet words 100% but there is not that addres everywhere i try. In electrum bread or etc.
When i restore wallet every other transactions are visible but the address is missing only that address.. Multibit had bugs that moment and said wrong password and etc..
If someone helps bounty will be 1000 euros.

iOS connection issues

Hey guys, I was able to compile and successfully run this lib on iOS and then created a fresh Bitcoin wallet but I'm getting tons of network connection issues, like:

134.119.20.251:40428 connecting
109.235.255.34:40428 connecting
18.205.18.126:40428 connect error: Connection refused

69.61.93.240:40428 connect error: Connection refused
69.61.93.240:40428 disconnected
....

As a result, my SPV client is unable to connect to the Bitcoin peer-to-peer network at all.

This same issue happens when running on the iOS simulator or an actual iOS device, on both testnet or maintest networks. (BTW, not sure if that matters at all, but my macOS firewall is currently disabled as well.)

Any thoughts? Thanks a lot for the lib!

Please send me y

Building as static iOS/macOS library

Hi! I'm trying to attach your perfect library to my project but I have some various issues in linking it via Xcode target.

How can I prebuild it to just importing like ".framework"? Is it possible at all? Maybe there are some tutorials I missed.

Thanks!

Modifying derivation path producing unexpected keys

I am attempting to support bip 49. I seem to be correctly deriving keys, but the address does not match what I am expecting.

Leveraging this site for comparison. https://iancoleman.io/bip39/

My test seed is
abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about
With a darivation path of m/49'/0'/0'/0

The first public and private keys are correct and matching whats in the test site, but the address is correct instead of the address:
37VucYSaXLCAsxYyAPfbSi9eh4iEcbShgf

I get:
1PkaFBUcyAccDp2Xo2K8MqduVMgMB792r2

Is there something else that needs to be changed to get the correct address?

[Question] Is this free software?

Question: Is BreadWallet completely Free Software?

Build error when compiled with C++ 11

Hi, I try to use bread wallet core as SDK of my C++ app compiled by Clang on macOS, but encountered some compile errors in the following code in BRInt.h.

inline static void UInt16SetBE(void *b2, uint16_t u)
{
    *(union _u16 { uint8_t u8[16/8]; } *)b2 = (union _u16) { (u >> 8) & 0xff, u & 0xff };
}

error: '_u16' cannot be defined in a type specifier
[build]     *(union _u16 { uint8_t u8[16/8]; } *)b2 = (union _u16) { (u >> 8) & 0xff, u & 0xff };

rror: non-constant-expression cannot be narrowed from type 'int' to 'uint8_t' (aka 'unsigned char') in initializer list [-Wc++11-narrowing]
[build]     *(union _u16 { uint8_t u8[16/8]; } *)b2 = (union _u16) { (u >> 8) & 0xff, u & 0xff };

note: insert an explicit cast to silence this issue
[build]     *(union _u16 { uint8_t u8[16/8]; } *)b2 = (union _u16) { (u >> 8) & 0xff, u & 0xff };

Even after I insert casting as following, it still shows _error: 'u16' cannot be defined in a type specifier

inline static void UInt16SetBE(void *b2, uint16_t u)
{
    *(union _u16 { uint8_t u8[16/8]; } *)b2 = (union _u16) { (uint8_t)((u >> 8) & 0xff), (uint8_t)(u & 0xff) };
}

I am not familiar with the syntax. Can someone help me?

Restore not finding transactions

Restoring a wallet with a modified derivation path does not restore transactions.

Where in core would I need to modify to ensure transactions are found in the Merkle blocks?

same seed, create address by bip32 ,the address not same

`
UInt512 seed = UINT512_ZERO;

Derivation Path

Is is possible to modify the derivation path and if so would that be done in BRBIP32sequence.c?

Memory crash when calling BRPeerManagerFree after new tx happen

I have a thread to monitor wallet, the thread code is copyed from test.c with little modifications,
After a new transaction happens and I let threadExit to 1 to quit the thread, the program crashed, the debug info is:
***** Error in `/data/breadwallet-core/test': free(): invalid pointer: 0x00007fffe4061520 *****

Can somebody know how to handle this problem?

RSK integration

I'm interested in integrating RSK network to Breadwallet.
RSK is a fork of Ethereum and, therefore, I assume that cloning and adapting ethereum folder should be necessary (but not sure if enough). Am I right?
Any guidance you can offer will be very helpful.

Any plan to start developing for EOS token?

same like title, does have any plan to start developing for EOS token?

Scrypt support?

paper key restore race condition

Under certain conditions, in particular, in a paper key restore, the merkleblock can arrive before the transaction. In this case, the transaction will not receive blockheight and timestamp in BRWalletUpdateTransaction as called by _peerRelayedBlock. When BRWalletRegisterTransaction is later called, BRWalletUpdateTransaction is never called again.

I'm trying to figure out if there is a way to look up stored merkleblocks for the transaction, or cache the UpdateTransaction info... maybe a map of txhash to block? or a BRSet of blocks to check for txs? I need a hash table!

[Feature Request] add TRON support

Hi breadwallet team, will you add support for TRON(TRX) and also all TRC10/TRC20 tokens?

Bitcoin Cash: Support aserti3-2d DAA

On November 15 there will be a planned network upgrade on the Bitcoin Cash network that will activate a new and non backwards compatible Difficulty Adjustment Algorithm called aserti3-2d. Breadwallet needs to implement it since the wallet is verifying the block headers and thus verifying the difficulty.

Specifications can be found here:
https://www.bitcoincash.org/spec/2020-11-15-upgrade.html
https://upgradespecs.bitcoincashnode.org/2020-11-15-upgrade/

Please note that there will also be an additional soft-fork as specified in the "Coinbase Rule" by Bitcoin ABC and most certainly a chain split since no other full node software is implementing it. Not implementing the soft-fork will let the wallet follow the chain with most Proof-of-Work.

Integration of other Algorithms

Is there a library available to have this fully compatible with Lyra2REv2?

How to compile the Android library?

I want to add a new token of my own chain, how should I operate? How to compile it? please help me

blocks received cannot be written to disk by saveBlocks callback

I can receive a bunch of block from peers, but the saveBlocks callback didn't be called in _peerRelayedBlock function. The printing is as followers:
