Elk is the easiest way to start building decentralized hardware projects.

With our development board, SDK, and companion app, you can do the following:

Build Blockchain-Connected Devices

Let your hardware accept and send payments, call and listen to events on smart contracts, and more.

Interact with your Hardware Privately

Communicate and interact with your hardware remotely without relying on a third party service or central servers.

Learn Blockchain Development

Explore and learn about blockchain technologies without the complexity through interactive hardware projects.

Build blockchain-connected devices in a snap!

Our development board is bundled with an Arduino-like SDK that provides an intuitive and simple interface for Ethereum, Bitcoin, and other decentralized technologies.

With only a few lines of code, you’ll be able to build blockchain-connected devices to do things you never thought possible.

Technologies supported in our SDK:

  • Ethereum
  • Bitcoin
  • Whisper (decentralized messaging)
  • Swarm (decentralized storage)
  • Status IM
  • And more to come!

Accept crypto payments

Build hardware projects that accept and send payments in Ethereum, Bitcoin, DAI, or any ERC20 token.

Call smart contracts

Build hardware projects that call and listen to events in Ethereum smart contracts.

Communicate Privately

Communicate privately with your devices using Whisper (decentralized messaging)

Store data in Swarm

Upload sensors data to Ethereum’s Swarm (decentralized storage)

Interact with your hardware privately and remotely with the Elk app.

We extended Ethereum’s Whisper protocol and built the Elk mobile app, an app that makes it trivial for you to interact with your hardware remotely and privately via Whisper through any mobile device.

Here’s all the code you need to be able to control a lightbulb remotely using our development board and the Elk app:

bool bulbState = false;
void setup() {
pinMode(A0, OUTPUT);
Elk.expose("Toggle", &toggle);
}
void toggle() {
digitalWrite(A0, !bulbState);
bulbState = !bulbState;
}

Features

Simple SDK

Our SDK is Arduino compatible and requires no setup and no prior knowledge in decentralization or how it works.

Blockchain Agnostic

While our SDK ships with Ethereum and Bitcoin support, Elk is designed from the ground up to be blockchain agnostic and support for more platforms will continually be added.

Truly Decentralized

By default and when possible, Elk runs a light node and communicates directly with the blockchain and not through a hosted service. Elk pushes decentralization to the edge!

Open Source

Our hardware and SDK will both be 100% open-source. Hack away!

Breadboard Compatible

We want to make your hard hardware life easy. Easily connect Elk with your sensors and actuators using your breadboard.

Frequently Asked Questions

  • Do you only support Ethereum and Bitcoin?

    No, Elk is meant to be a development board for multiple decentralized technologies. While Elk will initially ship with support for Ethereum and Bitcoin, support for additional blockchain technologies will continually be added.

    Also, our board is 100% open-source and we welcome contributions from the community to support more technologies.

  • Do I need to own crypto to use Elk?

    No! When building out projects that integrate with payments, you can always use test networks to test and play with your prototypes.

    Additionally, some protocols that we support, like Whisper, Swarm, and our Elk app, don't rely on crypto payments at all and you can use them without ever owning crypto.

  • How secure is the board?

    Elk doesn't have any form of hardware security and shouldn't at any point in time be used to hold significant amounts of (real) crypto assets. Our current focus with Elk is for prototyping and personal applications.

    For enterprise applications where security is paramount, please contact us.

  • When can I buy Elk?

    We will be launching our Kickstarter campaign in June 2019. Sign up on this page to stay tuned with updates and to get your early bird discount.

  • Is this an ICO?

    No.

Brought to you by the creators of 1Sheeld and the winners of ETHDenver 2018.

Elk (formerly Elkrem) was born out of the ETHDenver 2018 Hackathon when we won first place for presenting a prototype of a development board to ease building decentralized hardware applications.

We are also the creators of 1Sheeld, a hardware that turns your smartphone into 40+ Arduino shields. Since its inception 1Sheeld has powered tens of thousands of makers in 120+ countries.
