    PINGLEWARE Smart Contracts for Solidity

    The following is a collection of smart contracts for solidity that will help accelerate blockchain development and deployment.


    npm install @pingleware/contracts


    In your truffle project, import the appropriate smart contract in your new contract

    imports "@pingleware/contracts/contracts/finance/debt/ExemptDebtOffering.sol";
    contract MyExemptBond is ExemptDebtOffering {
        constructor() public {
            name = "My Exempt Bond";
            symbol = "MYB";

    When using, you can import directly from

    imports "";
    contract MyExemptBond is ExemptDebtOfferingBond {
        constructor() public {
            name = "My Exempt Bond";
            symbol = "MYB";

    Why Blockchain Could Prevent Another Theranos


    Before developing the Equity token smart contracts for exempt offerings, I research existing use cases and to my surprise, there were no existing use case. There were plenty of discussions without the implementation. The smart contract is open source, available for inspection by anyone. Also the smart contract can stay in compliance with the rules of an exempt offering by incorporating those restrictions whether timed or not, into the contract code. The most beneficial feature is the blockchain exempt equity token can offer liquidity of restricted securities when conditions have been satisfied to permit such transfers? The blockchain exempt equity token can also provide a future mechanism for exempt equity token conversion to public shares after an IPO/DPO has become effective. The blockchain exempt offering can be the first choice for unicorn startups, because the smart contract can be coded to restrict verified accredited investors ONLY from buying, selling and transferring the exempt equity tokens. Publishing an exempt equity token contract to the public blockchain does not violate the General Solicitation as long as no reference is made to solicitation of investors? A Defi DAPP is needed in conjunction with the exempt equity token contract to maintain the exemption of the offering through use restriction by accredited and qualified investors only! The Defi DAPP can be a mobile app which validates the investor one time on in a hosted environment and then adds their wallet to the authroized investor queue on the blockchain, further interaction is perform execlusively with the blockchain without any need to revisit the hosted environment unless changes and intervention are required?

    REMIX Webapp

    The remix desktop was rebuilt as a webapp because I found the straight-browser version to become slow and non-responsive. The webapp version can be downloaded from You should try installing the official desktop version from the Remix Team at If the application will no launch, then download the webapp version.


    Use the following command to interface with remix,

    > remixd -s ./ --remix-ide

    What's included?

    I have search for other smart contract implementations in various industries, and copied to this repository ensuring they compile cleanly without errors and warnings. There are prebuilt smart contracts

    Finance - Banking, Credit, Currency, Debt, Equity and Utility
    Real Estate
    Supply Chain Management
    Social Network

    Before launching an exempt equity or debt offering you are required to submit the appropriate form to the Security and Exchange Commission as well as to have a Private Placement Memorandum. Using a DAPP or decentralized application on the IPFS or interplanetary file system, to maintain KYC, AML and accredited investor vetting compliance for your restricted securities.

    State of the Project

    The project is currently in an alpha-beta state, which means that production use is not recommended. Production ready will be tagged as stable. NPMJS.COM repository permits the tagging of releases as stable. See the workflow.


    Skip to step #5, if deploying on a DEX like,

    1. Create the contracts for each exempt offering in accordance with SEC rules; 
       complete the Credit Report contract in compliance with the FCRA; 
       complete the Social Network contract that support community driven choice.
    2. Test the contracts on to fix implementation issues? 
       To import a contract from into remix, naivgate to the desired contract and
       press the view raw button, no copy and paste the URL of the raw file view.
    3. Implement a DAPP using HTML, CSS, and JavaScript (jQuery and vanilla - no other JS frameworks)
       that connect to each contract deployed on a local truffle-ganache configuration.
    4. Deploy on an ethereum testnet for further testing and public preview.
    5. Create a private placement memorandum with a qualified attorney review, 
    6. Register with the SEC as an EDGAR filer, obtain a CIK number, 
    7. File the appropriate exempt offering with the Security and Exchange Commission (SEC) via EDGAR, 
    8. Register as a Transfer Agent with the SEC using 
    9. Apply for a CUSIP at
    10. Prepare most recent balance sheet, profit and loss and retained earnings statements, 
        equivalent financial information for the two prior fiscal years
            Balance sheet -
            Profit and Loss -
            Retained Earnings Statement -
    11. Apply for a Ticker Symbol from FINRA using
    12. Signup at and reserve your symbol at, 
        finalized STO process on this network.
    12-A. (alternative). Deploy on ethereum mainnet using the symbol assigned by FINRA,
          integrate with a custom DAPP.
    13. Contact preselect accredited investors for participation.

    Liquidity and the Blockchain

    While a private placement has restricted liquidity, a public offering token using a S-1 filing does not have restricted liquidity, hence a CUSIP and ISIN numbers are both needed. The ideal method for unrestricted liquidity is to issue your public offering (S-1) on an established DEX, but I am discovering this to be more tedious and sometimes more costly than listing on NYSE, NASDAQ, AMEX, Pinksheets or any other brick and mortar exchange? The other option is create an alternative trading system (ATS) with an orderbook and order matching and register your ATS with the SEC. If your ATS is solely for your own company's securities, than FINRA, CFTC and NFA registration may not be needed? (check with your attorney)


    Crowdfunding is an exempt offering and highly regulated meaning, to perform a successful equity crowdfund campaign, you must use a registered SEC funding portal. A funding portal is registered with the SEC and regulated by FINRA. The list of current and expired crowdfunding portals/platforms can be found at

    One such funding portal, offering crowd funding on the blockchain through an Security Token Offering (STO). They also offer a Mini-STO. See the difference between the two at,

    "It depends on your situation.
    If a max total raise of $5 million USD is enough for your company to reach a meaningful milestone, or if you do not have up to $100,000 to spend upfront or if you have to move fast with your fundraising campaign, then Mini-STO is better. Otherwise and STO is better solution for your situation.
    Basically, the difference between the Mini-STO and STO boils down to the difference between Reg CF and Reg A+. Simple like that. ", -

    CRYPTOLAUNCH.US is the easiest crowwdfunding platform for equity offerings.


    Online Token Builder

    The following service,, a user can build a token, download the source code and launch through the platform (cost 0.1 ETH to launch)

    The available tokens include,

    - Asset Backed Currency
    - Equity Token
    - Fan Token
    - Fund
    - Game Token
    - Utility Token
    - Other Security Token

    with an option to make any offering into an ICO crowdsale.

    Asset Backed Currency


    An Asset-backed currency would be considered as an Asset-back security (ABS) as defined by the SEC. See finance/debt/

    SEC Asset-backed securities disclosure rules at

    ABS public registration uses form ABS-15G and ABS-EE ABS private registration uses form D

    Equity Token

    A Security Token represents an asset or an entitlement to an earning stream or dividends. In terms of their economic function, the tokens are comparable to equities, bonds or derivatives, and are expected to make a profit.

    Fan Token

    Fan tokens are a form of cryptocurrency that gives holders access to a variety of fan-related membership perks like voting on club decisions, rewards, merchandise designs and unique experiences.

    See more at

    Fan Tokens are typically an NFT. NFT is like a trading card or collectible, any gains made on the sale of the NFT is taxable. See


    A fund token would be a donation for a tax exempt non-profit organization, and a security for all others.

    Game Token

    An old incentive for the blockchain. User purchases a game token to be used in a game. As long as the game token is used for game play and redemption inside the game with no perceived financial gains, the game token would not be a security. See

    Utility Token

    A Utility Token provides access to the goods and services that a project launched or will launch in the future, and can be used as a type of discount or premium access to the services. A lot of tokens tend to be used specifically as a funding mechanism for companies.

    A Utility token would not be a security as long as trading/swapping with third parties is not provided. Utility token would be like a discount coupon book where you prepaid to get a future discount. See

    What is different between pingleware-contracts and other contract frameworks?

    While the other contract frameworks provide templates to help you build contracts, they fall short from real world model implementation. pingleware-contracts provide a template for real world use of smart contracts across many industries, saving you development time and expense?

    Getting Test Ether

    The following network faucet(s) give the most and permit one request per twenty four hours,

    Private Ethereum Network

    See for more information.

    1. Create a unique chainID and symbol, see to check for uniqueness. You chainID and networkID will be the same.
    2. (optional) If you want credibility for your private network, then consider taking your cryptocurrency public through an S-1, where the asset class is cryptocurrency.
        Then get a symbol assigned from FINRA ( Since you have a private network (private meaning separate from mainnet)
        you will need to register the network as an ATS (alternative trading system), as well as the issuer of the cryptocurrency, register as a transfer agent. You will
        also need to get a license as a Money Transmitter the jurisdictions that you conduct business. When you perform an S-1 the quantity is the maximum number of tokens that
        will be issued. The fee for filing an S-1 is $92.70 per $1,000,000 (, or
            total offering = token initial price * number of tokens (if you have a par value, then the minimum price is the par value)
            total_offering = $5 * 200,000 = $1,000,000
            filing_fee = (total_offering / 1000000) * 92.70 
        You can have multiple offerings of S-1, the first S-1 makes your company a public company.
        When you apply for a trading symbol from FINRA, requires a market maker (, because they will handle the KYC and AML for your clients, buying your token at a discount or par value. 

    Command line option,

    > geth --networkid <chainID>

    List Private Network on

    1. Clone the project
    2. Create a new file in ./_data/chains directory using the file convention of eip115-<chainID>.json
    3. Create a logo for your private network
    4. Copyright the logo.
    5. Publish your logo to a publicly accessible IPFS network
    6. Create a new file in ./_data/icons directory using the file convetion of <symbol>.json
    7. Check in changes to your account
    8. Create a pull request.
    9. Wait for your changes to be merged.

    End-of-Life Doctrine

    When a piece of software is useful, there should never be an EOL doctrine. The intention for this application is to achieve immoratlity ;). At some point of time in the future, this project may appear to be dead and abandon. The opposite will be true! When this project reaches that stage, this project has matured to a level where maintenance is minimal (mostly updating to latest version of Node).
