Melis Wallet

We are glad to introduce you to Melis, the revolutionary multi-account, multi-user, multi-device, multi-OS, user friendly and feature-rich wallet, for Bitcoin and Bitcoin Cash.


How to use it?

Android: search “Melis Wallet” on the play store.
IOS: search “Melis Wallet” on the Apple app store.
Desktop: you can download it here: https://melis.io/download.html
Web: https://wallet.melis.io/


Testnet

If you want to test Melis without using real bitcoins, you can use the Testnet version.

Android: search “Melis testnet” on the play store.   
Desktop: you can download it here: https://www-test.melis.io/download.html
Web: https://wallet-test.melis.io/


Why another wallet?

Other existing wallets focus on safety or ease of use, but not both. There are simple wallets for smartphones without security features or very secure desktop wallets for managing your savings that are quite unpractical to use.

Melis offers the best of all worlds: simplicity and security for desktop and mobile, in the same application.


How is it done?

With Melis you can create as many single or multi user accounts as you want. An account is a “sub-part” of your wallet, customized for your needs. You can choose the level of security, and the number of co-signers. Accounts are completely independent from each other, as if they are different wallets. Every account has its own balance and addresses.

A wallet can be configured on more than one device (Home computer, smartphones, tablets..). An important concept in Melis is the “primary device”. The primary device, which can be your home computer or another computer dedicated to the management of bitcoins and nothing else, is always able to access to all the configured accounts. The first instance of the wallet is considered the primary device but it is possible to elect any other instance (but only one at once) as primary device. Each account can be configured as “secure”, which makes it visible only on the primary device.
 
For example you can create an account with maximum level of security (protected by server signature, with spending limits) for your savings and flag it as secure (it will be displayed only on the primary device), or a simple account (single signature) for day to day spending, available on all the devices.

In the image below are represented some use-cases. Anyway there are endless possibilities:


There are already other wallets that can create multi-signature accounts pretty easily, but the key schemes are fixed and not configurable. With Melis you can create a multi-signature account between N people, where up to N signatures are required to sign a transaction, choosing if any of those should be mandatory.

In the image below you can see an example. To send a transaction Paul and another co-signer must sign the transaction.




Is it safe?

While Melis is still a Release Candidate and there could be possible bugs, we worked hard to avoid putting user funds in danger.

At beginning of 2017 we released a beta version to a number of testers and no dangerous issues have been found so far.

It is possible to configure spending limits in a time period, by account. Even if a thief gets access to your private keys or to your wallet, he would not be able to spend more than the limited amount, and gives you enough time to prevent further thefts disabling the compromised device or securing (hiding) the accounts.


Who knows/handles the private keys?

Melis and its servers never handle user’s private keys. Each user is in total control of their own keys. It is user’s responsibility to secure at least one backup of the credentials (mnemonics).

On GitHub it is possible to examine the source code ( https://github.com/melis-wallet ), and possibly rebuild the application yourself.


The future

We have a rich roadmap with lots of exciting features to be added. Follow us to get updates. You can subscribe to our newsletter through our website https://melis.io/ (very low traffic).

Melis is and will always be a free wallet.


Who are people behind Melis?

Melis is a company made of skilled developers with a deep passion for Bitcoin since the early days.


Why should I test it?

Melis has a common goal with members of the community: build a free, trustless wallet for everyday (personal and professional) use and to securely keep the savings.

The project is huge, our team is working full time since almost 3 years, and any feedback from bitcoin users from all over the world is both useful and highly appreciated.

What’s new in v1.1

  • Introduced the advanced send function: it allows “coin control” (choose which UTXO are involved in the transaction), multiple destinations, manual fee settings.
  • Signing a multi user transaction now requires one confirmation step.
  • Error messages about exceeded spending limits have been translated/localized.
  • The transaction details on transactions log now displays both the current fiat value of the transaction and the value at the time the transaction has been made.
  • Fixed several graphical interface layout glitches.
  • Improved two-factor authentication management.
  • In the account settings it is possible to show the list of every transaction, every generated address and every UTXO. From there it is now possible to sign messages and to export the private key.
  • Reconnection to Melis servers has been greatly improved.

The Apple IOS version is awaiting to be approved, and it will be available on the Apple Store soon.

Are you sure this wallet is safe? i just downloaded the windows version of Melis wallet and before i started to install I try it first to scan with virustotal scanner and here is the result.
https://www.virustotal.com/#/file/232f999a5cc155230e966e137fa51f07c88db03127673056f9f1b36a8d6cfee0/detection
It shows "2 engines detected this file"
Can you explain why this wallet detected by Yandex as a trojan.Agent!yuDtV16GIGQ?

Also would like to ask for an open source project to check if there is nothing malicious in your wallet.

Alas, it is a false positive. It is not the first time that an .exe file of a wallet is recognized as a virus. See for example the Electron case: https://github.com/electron/electron/issues/4485

Anyway, you can download our source code from Github: https://github.com/melis-wallet

Then you can execute the commands to build and run the program. This is the safest way to check if all things are all right. Specifically, the web page where you can build the wallet is the following: https://github.com/melis-wallet/melis-cm-client

Melis, the revolutionary multi-account, multi-user, multi-device, multi-OS, user friendly and feature-rich wallet, for Bitcoin and Bitcoin Cash, adds now Litecoin support.



Key features:

  • Native support for Bitcoin, Bitcoin Cash and Litecoin
  • A single wallet is able to handle an unlimited number of accounts of different kinds, single signature, multi signature, and multi user
  • The most advanced multi user implementation available, where you can create an account for example with these characteristics:
    • 5 users, where 1 signature is mandatory and any 2 of the remaining 4 are needed to authorize a transaction
    • 2of2 signatures where one of the two signatures is handled by the server so that it can enforce spending policies like TFA and limit of expenses per period (daily, weekly, monthly)
    • multi user accounts (for example 3of5) with added, mandatory, server signature
  • The server coordinates real time messaging between users so that at any time you can know the status of an "ongoing" transaction and the list of cosigners that have already signed
  • TFA for enhanced security, available also via Telegram (very handy!)
  • The server is smart enough to detect if someone sends BTCs to a BCH address of yours and viceversa, and in that case creates on the fly a new account in order to be able to recover the (otherwise lost, or difficult to retrieve) funds
  • Multi device support with native builds for Linux, Mac, Windows, iOS and Android in addition to the web: https://wallet.melis.io
  • A single backup using standard BIP39 mnemonics is valid and sufficient for an unlimited number of transactions, address and different account types
  • A special feature able to recognize the access to the wallet by a designated primary device that is the only one able to access secured accounts.
  • Accessing the wallet from every other device would be impossible to know that there are hidden accounts, with plausible deniability
  • Capability to create advanced transactions with multiple recipients, manual tuning of the fees and complete coin control
  • RBF support (Bitcoin only)
  • Untrusted server architecture where all the keys never leave the client and are in full control by the user
  • Completely open source client with rebuildable sources hosted on github: https://github.com/melis-wallet

Melis is not perfect nor complete yet and it is very much work in progress but completely usable in its current form. We are trying our best to make it a very powerful tool for advanced users.

A testnet version is available if someone wants to play with all the features without fear of making mistakes: https://wallet-test.melis.io

You can check in details Melis potential by watching our tutorial videos on our Youtube channel: https://www.youtube.com/channel/UC-RZeDwfFE4OXlHskXvZxZg?
