    About Melon


    Our usage token is called Melon token [MLN] and is a core component of the Melon project. It is designed to enjoy a “usage right” to the Melon protocol. To use the Melon protocol one has to use MLN token. This “usage fee” will most likely be imposed on trading. All MLN token that are paid by Users to access Melon will go into a smart contract called a “Multichain fund”. The purpose of this fund is to secure trustless connectivity to other blockchains as well as redeploying the Melon protocol to other blockchains with different properties. Making it in effect a multichain capable software for asset management. A maximum of 1,250,000 MLN will be created before the final version of the Melon protocol is deployed to the live network. Following the live deployment, a fixed amount of new token will be created periodically and be distributed towards the most widely used Modules of the Melon protocol. This incentivises maintenance and development of the Melon protocol even after its final version is deployed to the live network.

    Melon Protocol

    The Melon protocol allows digital asset managers to use blockchain technology to automate a lot of processes using code embedded in smart contracts.

    Melon Portal 


    The Melon portal is an interface or portal to the Melon protocol. Its main objective is to make the interactions with the Melon protocol as easy as possible. Contact us to become an early tester of the portal.

    Open-source and Transparent

    Asset management track-records are transparent and auditable by everyone everywhere at any time. Easily grow and share your reputation in the asset management space.

    Modular and Inclusive

    Melon is built from the start to be ever-expandable and flexible. A modular framework for easily adding new functionality and features in a permisionless way that rewards developers.

    Lowers Costs and Time

    By using blockchain technology, fixed and variable asset management costs as well as time requirements are drastically reduced. This enables a never-seen-before competitive environment for asset management strategies.

    Decentralised and Reliable

    By having decentralised storage and execution one can mitigate some of today's real world inefficiencies such as custody, counter-party and settlement. Melon creates a true alternative to traditional asset management.

  • Melon Token Launch

    Hello future Melon Protocol User!

    The Melon Contribution Period will soon be over (12pm CET, March 15th, 2017) and your Melon tokens will be unfrozen.

    This post will guide you through the process of interacting with your Melon tokens created during the Melon Contribution Period.

    Please read this thoroughly before accessing your tokens.

    This guide is for educational purposes only.

    Recap — What are Melon tokens?

    The Melon token “MLN” is a core component of the Melon protocol (that is being built by Melonport), and is designed to provide a “usage right” (usage license) to the Melon software. The Melon token follows the ERC20token standard, and is available only on the main Ethereum blockchain.

    Where can I find my Melon tokens?

    Your Melon tokens will have been distributed by the Melon Contribution Smart Contract System to the same address you used during the Melon Contribution period.

    For example:

    If you sent X Ether from the (hypothetical) account 0x005f7b35e60913cF95s3F1231Cb93B5700A116a6 to the Melon Contribution Contract, that “0x005f7…” address will have received Y Melon tokens back from the Contribution contract.

    How can I see my Melon tokens?

    Some Ethereum clients like Parity automatically identify any Melon tokens held in your account, so you will see them without any additional effort on your part.

    Others, such as Mist, Ethereum Wallet, My Ether Wallet and MetaMask for example require you to add in the appropriate data to “watch” any ERC20 tokens held in your account. This data can be found below under “Token Data”.

    The MelonToken Contract has been verified on Etherscan —

    For Mist/Ethereum Wallet, go to “Contracts” then scroll down, click “Watch Token” to add MLN, then add in the data below.

    For MyEtherWallet, choose the “Send Ether & Tokens” tab, select the wallet file/private key you used in the contribution and unlock your wallet, then click the “Add Custom Token” button on the left and add MLN using the data below.

    For MetaMask, you can go to and follow the steps for the Mist/Ethereum Wallet.

    Token Data

    Token Contract Address:


    Melon Token Name:


    Token Symbol:


    Decimal Places:



    Q: I can’t see any Melon tokens in my account?

    A: Check your client is fully synced. If there are still no tokens, check you have entered the correct token data into your Ethereum client. If there are still no tokens, check you are using the address you used during the Contribution Period. If there are still no tokens, check your transaction with the Melon Contribution Smart Contract System was accepted. If there are still no tokens, try a different client than the one you are using and check again. If then you still have issues, join us on the Melonport Slack.

    Q: Where can I trade my Melon tokens?

    A: Any exchanges or platforms who wish to engage in Melon token trading will make their own announcements.

    Q: Why can’t I send my Melon tokens to another account?

    A: Melon tokens can be sent to other accounts starting 12pm CET (11am UTC) on the 15th of March, 2017. Until that point, they are frozen in the account that was used to generate them by sending Ether to the Contribution Smart Contract System.

  • Melonport The Difference Between Protocol Tokens and Traditional Asset Tokens

    By way of background, one of our biggest motivations in building the Melon protocol is the creation of an infrastructure for managing digital tokens; what we firmly believe to be a fast-emerging asset class.

    In the last two years, hundreds of digital tokens have emerged. To avoid confusion we can break up “digital tokens” into two broad sub-groups;

    Protocol Tokens (PTs)= Digital tokens that are governed by a coded
    protocol. The rules of the protocol are enforced by the underlying
    blockchain technology. They are generally not linked to any
    “centralised” entity or any “traditional” real-world assets.

    Traditional Asset Tokens (TATs)= Digital tokens that represent a “traditional” asset, such as fiat currency (e.g Tramonex’s ERC20 GBP on Ethereum, Decentralised Capital’s ERC20 Euro) or precious metals (Digix’s ERC20 token representing gold for example). These assets are still dependent on traditional financial and legal systems.

    It is important to distinguish between these two sub-groups because they
    will have different properties over time. Protocol tokens benefit from a
    very interesting collection of properties which is why we believe they
    will soon be a critical element in the achievement of diverse portfolio

    “Harry Markowitz called diversification a “free lunch.” We spend all our time in intro. econ. figuring out there is no such thing as a free lunch but Markowitz tells us that diversification is a free lunch. “ — Open Yale Courses

    Harry Markowitz — 1990 Nobel Memorial Prize winner in Economic Sciences. The secret to great portfolio management is good diversification and uncorrelated returns. It is hard to find back-tested data on protocol tokens, so we can use the chart below to illustrate that even against asset classes which are considered “safe” such as gold and U.S Government Treasuries, protocol tokens have a surprisingly low correlation.

    Seeking Alpha —

    Some of the reasons for protocol tokens having low correlation to other asset classes come about from their independence from today’s financial system. They are bound by the rules of their underlying protocol, which is supposed to be “un-corruptible”. As such, they are not so exposed to any hidden erosion in value (eg. Quantitative Easing) or traditional financial risks that have emerged over the years in financial markets.

    The way that Traditional Assets are being tokenized — the processes
    involved, how they then connect back to the “real world” — is
    intriguing, and clearly part of a growing trend.
    The underlying asset of a Traditional Asset Token is typically a “real
    world asset” which is governed by one (or more) centralised party but exists independently of the token’s existence on a blockchain.

    Adding traditional assets onto blockchain technology requires for them to first be held in custody by a centralised party. They can then be tracked via an issuance of tokens which represent the ownership of assets on chain with the security guarantees that blockchains provide. Trading and settlement can happen in a matter of seconds and at minimal cost (compared to t+3 + high fees, for example) due to the underlying technology. In theory, these assets are also divisible into smaller units, and as a consequence become more easily accessible.

    Our Vision?

    We are primarily building “Melon”, as an infrastructure to set up and manage funds built around protocol tokens — an asset class which we fundamentally believe will have a place in every single diversified portfolio ten years from now.

    Traditional asset tokens are a newer trend — Assets in the real world are fast becoming tokenizes through a variety of novel and innovative mechanisms. Some examples include art (Ed Fornieles), music (Ujo Music), intellectual property, equities (Overstock & Otonomos), fiat currencies (Santander), real estate (REIDAO) just to name a few examples.

    If you believe (like we do), that traditional asset tokens are also an emerging asset class, it will then be possible one day to apply the Melon protocol to that asset class too, enabling traditional asset managers to save costs and pass them on to their investors. In theory, there is no reason why you can’t run a truly diverse portfolio across the full spectrum of all these assets in one Melon portfolio with the efficiencies that come along with it!

    This idea is incredibly exciting to us as a means of democratizing asset management and allowing a deeper talent pool to rise, enabled through great technology. Hundreds of trillions of dollars worth of assets around the world now have the potential to be tracked, trusted and traded on your favourite blockchain, and perhaps even sooner than you can imagine!
