<h2>Introduction</h2>

The availability of payment systems greatly simplifies the life of our society. With their help, we can pay for many services without even leaving our own home, but along with advantages there are disadvantages. To solve existing problems in payment systems, as well as to modernize existing technologies, a Puma Pay project was created.

<h2>Project information</h2>

Puma Pay - is a universal open source protocol based on a blockbuster with a unique PullPayment archetype.

The Pull protocol (a network communication technology in which the initial data request is made by the client, and the response is generated by the server) will differ significantly from standard payment methods such as credit cards, crypto-currencies, and so on. This protocol solves existing problems by means of a set of tools designed to facilitate business processes.

<h2>Advantages</h2>

Multifunctional, scalable protocol that supports a full set of billing methods

Complete billing solution

Excluding excessive commissions for transactions from intermediaries that range from ~ 3% to 15%

Ability to make all-round payments, in any form of 
payment using Blockchain

Flexibility, this protocol can be customized for specific user needs

The project has strong partnerships.

Exclusion of fraudulent actions 

Pull protocol from Puma Pay is designed for the following purposes :

Increase the use of crypto currency in the online and offline markets at commercial levels

Decentralization of the billing industry
<h2>PullContract is used for the following operations :</h2>

Fulfillment of payments with a fixed amount;
Conducting transactions at the time of use;
Payments of regular payments in due time;
Making limited and divided payments.
Ecosystem

<h2>PumaPay Token Contract</h2>

This is the latest version of the ERC223 contract token, useful for adding flexibility to its payment and transfer protocol. It will work as a register for PumaPay and track the balances associated with each address and associated accounts with Pullcontracts and Limited. The basic notes of Token Contract will be managed through:

PullContracts Approvals

Executing PullContracts

Adding Limits to Accounts

<h2>Current enes PumaPay (the PMA)</h2>
PMA tokens will be based on a protocol ecosystem and can be used with launch partners from the date of its release. It acts as a payment mechanism used in the PumaPay protocol, and is based on the ERC233 standard. The token has the function of a comprehensive "all-in-one" billing mechanism, which makes it different from other crypto conversions.

<h2>Score</h2>
The account will be executed at a common address to track the balance of the PMA token, the Limiters, and the PullContracts associated with that particular address.

<h2>Authorizers</h2>
It will work as a modular component to set a condition for determining whether to pull PullContract or to request money from an account. Authors can be linked together in PullContract in order to make its development more simple and simple for traders.

<h2>PullContracts</h2>
It will be recognized as an intellectual contract, which is a payment relationship between accounts and allows you to transfer tokens. This will allow you to flexibly and easily implement various functions and payment mechanism.

<h2>Limiters</h2>
The account user can add this component on the chain to set a different quantitative limit for a particular account.

<h2>Purse PMA</h2>
The PMA wallet will be used to perform payment interactions between accounts. These interactions contain PullContracts, previous transactions, and display the account balance. The company develops its wallet in two versions:

The wallet is designed in the Android version, and then for iOS for mobile applications.

The second version is for applications based on Chrome

<h2>SDK and API protocol</h2>
The PMA SDK contains a set of tools for expanding the network and facilitates the adoption of the Merchants protocol. It will provide developers with the tools necessary to use the protocol. The flexibility of PullContracts is very beneficial for reducing technical failures of the contract token.

<h2>Cases of using the PullPayment PMA protocol</h2>
One of the most important features of the Protocol is its flexibility. It is carefully designed by implementing a unique solution that allows sellers and customers to use different types of billing mechanism to achieve their basic needs. Here we give examples of using the PMA protocol, which works on a block chain.

<h2>Periodic payments with a fixed amount</h2>
The protocol will allow you to create contracts that charge a fixed amount in accordance with the time, for example, subscription fees, monthly payments.

<h2>Pay-Per-Use</h2>
Using Pull Contracts to charge customers based on payment for use, for example, for a fee for expert advice


<h2>Token</h2>

The PumaPay project will release its own token PMA token , which is created on the blockchain ethereum standard ERC-223 . With this token, you will be able to feel the advantages of the platform, access to premium services. Also, the PMA token will be a crypto currency that can be sold on exchanges.


<h2>Conclusion</h2>

The PumaPay project seeks to modernize the view of billing through the tools provided by the tools of their platform to improve existing processing systems, making payments. Also, the project platform includes many components, each of which solves certain problems, but in total they form the PumaPay ecosystem.
