Overview

🏦 AnyLedger Embedded Wallet for Internet of Things

C crypto libraries to safely manage, generate and store private keys, to generate blockchain addresses and to sign transactions.

Additionally, it contains a RTOS app (Zephyr). The current implementation uses Ethereum and HyperLedger, but the same architecture will be used for all the other chains. The current implementation supports 100+ hardware platforms and is mainly bug tested on Nordic nRF52840.

Any IoT device flashing the embedded wallet can safely connect to a given blockchain, do transactions and interact with smart contracts.

Compilation

Dependencies

Linux (Ubuntu)

On a fresh Ubuntu:18.04 docker image. Adapt as appropriate to your distro.

apt-get update
apt-get install libgtest-dev g++ make cmake wget build-essential clang clang-tidy ninja-build git python3-pip protobuf-compiler python-protobuf -y

# Ubuntu's libgtest-dev is only the source. You have to compile them manually.
cd /usr/src/gtest; cmake .; cmake --build . --target install 

# Install Ethereum Solidity compiler
apt-get install software-properties-common -y && add-apt-repository ppa:ethereum/ethereum -y && apt-get update
apt-get install solc -y

# without this, you will get a Python 3 ASCII/UTF8 error on Ubuntu
export LC_ALL=C.UTF-8
export LANG=C.UTF-8
cd /
git clone https://github.com/AnyLedger/anyledger-wallet

alias build='rm -rf build; mkdir build; cd build; cmake -GNinja ../; ninja; cd ..'

cd anyledger-wallet; pip3 install --user -r requirements.txt; build

macOS

GTest:

git clone https://github.com/google/googletest 
cd googletest  
mkdir build  
cd build  
cmake ..  
make  
make install

Additional dependencies (installed using Homebrew):

brew install gcc make cmake wget ninja nanopb-generator protobuf pkgconfig

Python (this is required for ABI compiler)

pip3 install --user -r requirements.txt

solidity compiler

A working solc should be available in your $PATH. See the Installation instructions.

x86 build

This build is used to develop and test the wallet library on your desktop.

1. clone wallet repo git clone git@github.com:AnyLedger/anyledger-wallet.git && cd anyledger-wallet

2. create build directory and generate build targets mkdir build && cd build && cmake -GNinja ../

3. compile the library & run the tests ninja && ctest

zephyr build

Prerequisites: a working zephyr SDK (at least v0.9.5), see here for instructions. Please make sure you can compile and flash at least blinky example before building the wallet.

1. clone wallet repo to the zephyr's samples directory mkdir samples/anyledger/ && git clone git@github.com:AnyLedger/anyledger-wallet.git

2. create build directory and generate build targets cd samples/anyledger/anyledger-wallet/build && cmake -GNinja -DBOARD=nrf52840_pca10056 -DBUILD_XCOMPILE=1 ../

3. compile & flash the firmware ninja && ninja flash
