In case you didn't know, OpenRelay the company is powered by OpenRelay the software! OpenRelay (the software) is an open order book built on a powerful open source microservice architecture that makes finding orders and filling them via the 0x Protocol fast and efficient at any scale. We run our own instance of the software to power our business, but because it's open source, you can stand up your own instance and independently operate a relay tailored to your specific needs. Want to see how it works? Check it out on Github!


Embiggen (MBGN) is the ERC20 token that grows in your wallet! It offers a way to introduce new currency by providing it to all MBGN holders at once, proportionally to the amount of MBGN they hold (at a rate of 10% per annum, compounded hourly). You can think of it like a stock split; the total supply of the token is increased while each holder's share of the pie stays the same size.


NotCoin is an ERC20 token that enables "one-sided" exchanges. In otherwords, if you want to use an exchange contract to offer a token (such as Embiggen) without asking for a different token in return, NotCoin gets the job done. OpenRelay invented NotCoin to facilitate the Embiggen Airdrop, because we literally wanted to give away Embiggen. Hypothetically though, it could be used in any exchange where a token is being offered in exchange for something other than a token (like payment via fiat currency, for example).

Embiggen Airdrop dApp

We developed the Embiggen Airdrop dApp to enable users to claim Embiggen. The dApp is meant to prepare people for token trading by walking them through the process of setting up a web3 enabled browser, acquiring the necessary ETH, and claiming Embiggen in just a few easy steps. By the time they have claimed some Embiggen, they have everything they need to get deeper into the decentralized trading ecosystem.


Fling is a dApp for sending tokens to a lot of different addresses at once in just two transactions. The smart contract powering Fling was originally created to help us prepare for the Embiggen Airdrop, but after others expressed interest in a GUI-driven interface to the contract's functionality, we created the Fling dApp. More a love letter to the Ethereum community than a product, Fling demonstrates what is possible when clever smart contracts meet easy-to-use interfaces. (Also, it has a pretty sweet trebuchet graphic.)

Affiliate Portal

The OpenRelay Affiliate Portal dApp is a GUI-driven gateway that developers can use to 1) sign up for the OpenRelay Affiliates Program, and 2) view and redeem fees shared when affiliate-created dApps generate fees (we share 80% of fees generated by affiliates, with affiliates). The dApp allows developers to sign up, and then once they do, provides a dashboard interface to view and redeem fees. Simple, no?
