Dether (DTR) - BREAKING BARRIERS TO ETHEREUM MASS ADOPTION
WHAT IS DETHER?
Dether provides a decentralized peer-to-peer ether network that enables anyone on Earth to buy ether with
cash and spend it at physical stores nearby. No bank account is needed, just a mobile phone with internet
access. Our belief is that the beauty and power of the Ethereum technology should be easily accessible to
We’ve decided to put all of our energy and that of the Ethereum community into helping us build the first
trustless solution that will allow anyone to be able to interact with the Ethereum blockchain no matter who
you are, where you are, and without the need for a middleman.
BREAKING BARRIERS TO ETHEREUM MASS ADOPTION
As Satoshi Nakamoto envisioned the first blockchain use case as a “peer-to-peer electronic cash system,”
people all over the globe have been increasingly using not only bitcoin, but also cryptocurrency, as a means
With cryptocurrency you can now:
Buy a Subway sandwich in Buenos Aires.
Buy a painting in Paris.
Pay your children’s tuition fees in New York City.
Buy a deli sandwich in Melbourne.
Buy a camera in Tokyo.
And that’s just the beginning.
In this context, mobile phones are the new banks. And cryptocurrency is the new money. That’s the reason
we’ve also shaped the Dether map as a decentralized solution for any physical store willing to accept ether
as a means of payment.
No credit or debit card is needed to spend ether at physical stores.
CUTTING-EDGE APP FOR ETHEREUM MASS ADOPTION
Dether is the world’s first peer-to-peer ether network. It enables anyone who has a smartphone to buy and
sell ether using cash and spend it at physical stores listed on the Dether map.
Dether creates a worldwide ecosystem of ether buyers, sellers and physical stores willing to trade ether
for fiat cash and accept it as a means of payment. Dether provides the infrastructure for people to embrace
Ethereum technology in their everyday lives. Dether is available on any smartphone. No bank account is
needed to buy and sell ether. No credit or debit card is needed to spend ether at physical stores.
BUY AND SELL ETHER. ANYWHERE. ANYTIME. WITH CASH.
Dether offers the unique ability to let anyone safely buy and sell ether anywhere, anytime, with cash.
Because we believe that Ethereum won’t know mass adoption until it’s easily and quickly accessible to
anyone on Earth, we decided to create the first Dapp that brings the key solution in order to interact with
the Ethereum blockchain from anywhere in the world.
• The fastest and easiest way for anyone to buy ether
Dether offers the unique opportunity to have access to ether within
minutes by using a phone and spending cash.
Users are able to discover ether sellers, called tellers, near them on
the Dether map, their ETH/fiat rate, the fees that they take, and chat
anonymously with them. Buyers are free to engage a conversation
with the seller they want to trade with in order to agree on the trading
conditions and the meeting point to exchange ether for cash.
Any individual that has cash is able to buy ether on Dether. Cash is used
in all countries across the globe whether or not a person is unbanked.
And the adoption of smartphones is increasing all over the world. At the
crossroads of cash usage and increasing smartphone adoption is Dether.
Its unique solution gives anyone the opportunity to access ether, and
thus Ethereum blockchain, by spending cash. Dether aims at unleashing
the potential of Ethereum technology by providing a quick, easy and
secure gateway to the decentralized future.
• A cross-border market for ether tellers
Any ether owner can officially become a seller on Dether and benefit from a new, profitable activity.
Ether sellers can now become mobile “PTM” (People Teller Machine) by being on the Dether map and selling
ether for fiat currency anywhere in the world at any time. Sellers are free to set up their own ETH/fiat rate
and their own fees.
USE YOUR ETHER IN PHYSICAL STORES ALL OVER THE WORLD
• Spend ether at local stores, shops and businesses
On Dether, users discover physical stores near them that accept ether.
As Ethereum popularity is quickly increasing throughout the world,
more and more businesses are accepting ether.
Today, buying a Subway sandwich in Buenos Aires with cryptocurrency,
a deli sandwich in Melbourne or a camera in Japan, is now possible.
Tomorrow, the Dether map will give everyone the opportunity to
discover all of the places nearby where ether is accepted.
Dether users are able to discover shops near them that:
- accept ether as a means of payment
- are willing to buy or sell ether for cash
Users are able to spend their ether without the need for a bank account or a credit/debit card. For specific
needs, users are able to type the kind of physical stores they are looking for (e.g.: “restaurant”) in their city
to see which ones are accepting ether.
• Adding their own shops to the Dether map and expanding their businesses
Shop owners can let the whole world know that they’re now accepting ether! As the number of ether
buyers and tellers that use the Dether map will grow rapidly, physical stores are also able to be part of the
ecosystem by being listed on the Dether map.
Thanks to an auction mechanism, shops will compete with other businesses nearby for better visibility on
the Dether map. Similarly, like on any search engine or promotional marketplace, physical stores are able to
bet on specific key words and expressions to be more visible to Dether users on the map.
In addition, Dether will offer a complete back-office system to any shop wishing to accept ether, in order to
manage their liquidity and keep up with cryptocurrency fluctuations, thus having the possibility to directly
convert received ether into fiat currency.
In order to embrace our vision of creating the world’s first decentralized application for ether buyers, sellers
and physical shops, Dether introduces the ÐTR token.
1 WHAT IS THE ÐTR TOKEN?
ÐTR is the ERC20 token that allows people from all over the world to participate in Dether’s development.
Dether proposes a freemium model, where users are incentivized to use ÐTR tokens to unlock additional
features on Dether as a seller or a physical shop and have more visibility on the Dether map. Moreover,
Dether proposes a model where the quantity of ÐTR in circulation will be deflationist throughout time
thanks to the ÐTR Token Buyback Program.
2 WHY LAUNCH THE ÐTR TOKEN?
Dether relies on ÐTR token holders for its future development. ÐTR tokens will enable the Dether ecosystem
ÐTR tokens serve two main goals:
• ÐTR is the key token needed to unlock additional features and ensure better visibility on the Dether
map. As a teller or a physical store, staking ÐTR tokens is required in order to increase his or her
visibility on the Dether map to buyers. When multiple sellers or physical shops who have ÐTR tokens
are competing for a trading zone on the Dether’s map, an auction system chooses the winner for a
certain period of time.
• Launch a buyback program of ÐTR tokens in order to decrease the quantity of ÐTR tokens available on
public markets over time as Dether’s success worldwide increases and add liquidity to the market.
3. USING ÐTR TOKENS FOR VISIBILITY ON THE DETHER MAP AND ZONE INDEXING SYSTEM
Using ÐTR tokens in the Dether app will allow tellers and physical shops to have better visibility. They are
given the possibility of owning a zone through an auction system.
The Dether map will be divided into small areas of square meters (zone indexing system) in order to precisely
locate each area on Earth. Therefore, it will be possible to identify and categorize each crypto-related
service. In order to increase accuracy and avoid spam, different referencing systems will be available: one
organic, and one premium system accessible through the ÐTR token.
The Dether map aims at referencing the worldwide ecosystem of ether sellers (called tellers) and physical
stores. Therefore, there are two types of ether seller entities on the app: tellers and physical shops. Each of
them has their own registration process and a user cycle.
Tellers: a teller represents a legal entity (a human being, firm etc.) willing to sell ether at a given price and
in accordance with the legal limitations of the country from which he or she operates.
Physical stores: A physical store represents a legal entity registered in its country, willing to be visible on
the Dether map as a store accepting ether as a means of payment. Said store will also be able to broadcast
commercial advertisements regarding its location.
Organic indexing system
• For tellers: The more a teller trades, the greater organic visibility they will have on the Dether map.
The radius of his trading location point will expand, as well as his visibility on different zoom views on the
• For shops: Shops are organically visible through keyword searches, according to the payments they
5.3.2 Premium indexing system
Directly linked to the zoning system, tellers and shops have the ability to own a zone in which they have
• For tellers: Tellers will have exclusivity if they own a zone. All of the other tellers on that zone will
• For shops: If a shop owns a zone, it has exclusivity on said zone. All of the other shops around will
only be visible on the smallest zoom level, with limited information shown. Once a sufficient number of
physical stores are listed, Dether will set up a keyword system, enabling every physical store to add “tags”
that match the business’s description. For competitive areas, a keyword auction system will be set up for a
given geographical area. Thus, physical stores will be able to appear in priority over a given area, according
to the keywords entered by users in the search bar of the Dether map.
How will the auction system work? An entity opens a bid for an area by making a deposit. For the next
24 hours, any other entity can bid to appear on this area. After 24 hours, the entity that made the largest
deposit takes possession of the area. At any time, an entity may reopen an auction to take possession of
the zone. From then on, entities have 24 hours to bid to appear on this area. In the meantime, the current
owner of the area keeps it until the auction is over. A monthly fee between 0.05% and 0.1% of the deposit
will be taken in order to feed the ÐTR Buyback Program Fund, which intends to constantly buy ÐTR tokens
back and burn them.

Dether Development Transparency — Part 1
Unveiling Dether’s P2P network of Ether traders and shops.
This blog post is the first in a series of articles describing the technical choices of Dether, and our long term vision. In this first article, we will answer all the major questions we’ve received up until now about our major choices thus far.
1/ Why Ethereum?
People often ask us why we’ve chosen to help cryptocurrency reach mass adoption using Ethereum and not the first cryptocurrency (in term of marketcap) which is Bitcoin. There are different reasons for that.
The first is that today, Ethereum is the most reliable blockchain for smart contracts. And this is crucial as we see Dether and its protocol to be fully decentralized, and reachable everywhere by everyone. Also, as true Ethereum believers, we strongly believe there will be a growing demand for an easy access to ether, and also tokens. Moreover, ether can be an easy entry to get other cryptocurrency in general, as in most exchanges, ETH is paired directly with all other major cryptocurrency.
2/ Why do you have a token instead of taking a fee?
Having an easy access to get ether using cash is a need shared by a lot of decentralized applications (Dapps). We have verified this assertion after the launch of Dether’s alpha, as we have been contacted by many teams working on Dapps. That’s the reason why Dether will have an API to enable an easy access to all information we have gathered.
Using a private paying API through Ethereum makes no sense. However, it makes more sense to develop a protocol based on a token instead of a centralized application taking fees.
In order to succeed in creating a reliable protocol with an incentive for using it, you need your own token to keep and share the value created in your ecosystem.
The drawback of having a token is that you create friction and add hidden costs to your users’ interactions (conversion cost etc..). That’s why we will have a freemium token system based protocol, where it will be possible to use the protocol without tokens, but users will be incentivised to use it. We will go in depth in Dether’s token system in further articles, but it aims with multiple mechanisms to incentive everyone in the app, without creating friction for new users.
For more information about the use of the ÐTR token, you can find all the explanations related to our token model in Dether’s whitepaper: http://whitepaper.dether.io
3/ Why have you chosen to use a PWA (progressive web app) instead of a native app?https://alpha.dether.io
We launched Dether’s alpha on October 2017 on Ethereum Kovan testnet.
We have chosen to use a PWA because it facilitates a lot of things. First, you don’t have to go through any AppStore validation. And currently, for a crypto-related mobile app, it can be challenging to be validated by the AppStore.
Also your app is platform agnostic. A progressive app may run normally like a website, but we chose to encourage people to add it on their phone home screen, to recreate the mobile experience. So we put in place a system where we detect if the users are using their browser and show them a very simple installation process to follow. And once we detect that the app is running through the home screen link, we launch the real app. Thus, we recreate a mobile app experience, with an easy version management, and AppStore censorship resistant.
As a result, in less than a month, more than 3.000 people all over the world have installed Dether on their mobile phone and used it.
4/ Do you really have no back-end?
Yes, the alpha runs without any back-end, as we just need some external API, like mapbox for the map, and our own Ethereum provider. That’s it! For the rest, it’s just web3 to Ethereum node communication. This architecture has some drawbacks: loading a lot of data from an Ethereum node, can be a struggle, so for example, in the first version of alpha, we were loading all the ether sellers on the map.Ether sellers located on the Dether map
But as more and more ether sellers were added, it’s too long to handle this data. Now, we load only the ether sellers from the country where you are. And for the first mainnet beta version, we will load only the sellers from your postal code and the ones closest to you.
5/ How do you handle a user’s private key?
We create the mnemonic phrase with entropy generated by the user’s phone move, and generate one private key. Once created, we encrypt it all with the password provided by the user and store it in the local storage of the app.
For every transaction in the app, we decrypt the private key with the password provided by the user to sign the transaction (but never keep the private key in memory), and broadcast the signed transaction through our Ethereum node.
This way, the private key is never stored decrypted in the system, and it never leaves the user’s device.
6/ Do you plan to add other cryptocurrencies?
We will add ERC20 tokens in Dether’s future version. It will be possible for users to buy and sell token using cash anywhere in the world. For other cryptocurrency, we are looking for solutions to bridge the Ethereum ecosystem and other cryptocurrency.Rootstock (RSK) <> Dether @Devcon3
For now, we are thinking about Cosmos, which will be soon available, and Rootstock (RSK) which will be an EVM side chain to Bitcoin. Our main concern about that is that layer should be pegged in some way with our token. And it’s definitely something we would like to add for 2018.
