Polygon DApp Development

Introduction

Ethereum is a great project but currently, transaction fees are very expensive. There are many alternative blockchains with lower transaction fees. One of these blockchains is Polygon. Polygon blockchain uses the same development tools as Ethereum like solidity, web3, etc, and also maintains a connection to the Ethereum network. This means you still benefit from the network effect of Ethereum polygon is getting a lot of traction and if you are a blockchain developer you need to understand how it works.

Polygon development company

Polygon Matic started in 2017 as a Matic network. In 2017, the first conversations around scaling started because of the cryptic crypto kitties episode. At that time, it was hard to talk about the serious adoption of blockchain because the technology was not scalable and was costly to adopt. Vitallik came up with a paper citing plasma technology as a way of solving the scalability problems of Ethereum. One of the Polygon founders was a plasma researcher, he came up with his hybrid plasma chain PoS approach, a chain tethered to Ethereum which behaves like a committed chain. Three Indian developers polygon worked together to find a solution to Ethereum problems which resulted in the creation of Matic and now rebranded to the polygon network. Even though they rebranded to the Polygon Network, the coin is still called the Matic coin.

Polygon is a layer two scaling platform that allows Ethereum based applications to tackle the scalability problems of the mainchain. Although it leverages Ethereum's security and its primary focus is to increase the usage of DeFi applications. The network currently hosts over 3000 decentralized applications, 80 of which are big names that migrated from the Ethereum main chain. Since Polygon is so similar to Ethereum, many blockchain projects that develop useful tools will move them from the Ethereum blockchain network to other EVM blockchains like Polygon. In that way, they can remain on Ethereum while offering a better experience to their users. EVM stands for Ethereum Virtual Machine which runs the actual code or smart contract written by developers during blockchain development.

Polygon is EVM compatible and so are Binance Smart Chain, Fantom, and a few other blockchain networks. They all utilize the main Ethereum code since they run the same codebase, and developers can simply move their project over to a new network.

Proof of stake

Polygon proof of stake chain is simply a side chain to Ethereum and utilizes its proof of stake consensus mechanism. Although they are quite similar and about the same, there are lots of changes that make Polygon's RPC different. A very important factor is, that it's way faster and can handle way more transactions per second. Also, Polygon is much more affordable to the end-users.

Technically the polygon network is more than a side chain. One of the core ideas behind polygon is to equip developers with user-friendly and flexible tools. That way these developers can fast-track Ethereum's transformation into a multi-chain platform. Polygon sidechain project out there working to create a better experience on Ethereum. When they achieve this, developers can easily create all kinds of different scaling solutions that they can use with Ethereum like completely separate chains or any other side chains that they desire. The polygon proof of stake chain is just one way to scale Ethereum. In reality, polygon plans to create many different solutions for its users.

So in one sentence polygon is Ethereum but with lower gas fees. Right now, to transfer your Ethereum from one account to another, you will incur about $25 in fees on average. On the polygon network, however, the same transaction will cost only a few cents.

How the Polygon Network works

Polygon is a layer2 scaling solution originally designed for the Ethereum blockchain. The proof of stake protocol serves and is connected to the Ethereum chain. The commit chain functions as a transaction network that operates close to the real chain. The chain is the same mechanism that helps Polygon to work alongside Ethereum.

Polygon's commit chain groups up clusters of transactions and processes them all together before sending the data back to the main Ethereum chain. Instead of sending the entire record of all the transactions, Polygon simply takes a single snapshot now and then, so that the Ethereum chain can still understand what is happening but without processing tons of data. This is why the polygon network can process up to 65000 transactions per second. Some experts predict that a time will come when developers will host thousands of chains and work with Ethereum to increase throughput up to millions of transactions per second.

Polygon’s architecture

Polygon’s architecture runs on a 4 layer system comprising of the Ethereum layer, the security layer, the polygon networks layer, and finally the execution layer.

Ethereum layer

The Ethereum layer is made up of different Ethereum based smart contracts. These contracts are in charge of staking, transactions approval, and interaction between the Ethereum new blockchain network and numerous polygon chains. The Ethereum layer also helps Polygon check transactions from time to time.

Security layer

It works alongside Ethereum's network effects to provide validator services giving chains an additional layer of security. It’s important to note that both the security layer and the Ethereum layer are optional. They are not required for the polygon to work.

Polygon network layer

It’s the ecosystem of projects or blockchain networks developed on the adding Polygon. Every project or blockchain technology that exists within this ecosystem has its community. Where local consensus is reached and blocks are produced.

We have developed around 50+ blockchain projects and helped companies to raise funds.

Execution layer

This is popularly known as polygons Ethereum Virtual Machine. Its main function is to execute smart contracts on the actual Polygon Blockchain. The compatibility with the EVM and the user experience for developers and programmers is smooth while using the Ethereum chain.

Polygon tokenomics:

The polygon network has a native token called Matic. Which has been trading for around 2 dollars with a market capitalization value of around 13 billion dollars. Matic tokens are distributed monthly and have a total supply of 10 billion tokens of which nearly 6.8 billion is already in circulation. Some Matic tokens are held for staking rewards and token deposits with a time-locked release. Initially, the developers sold around 3.8 % of Matic's total supply in their initial private launch back in 2017. Later, they had an initial exchange offering where they sold another 19% of their maximum supply. The development teams own 16% of the supply, the advisors have 4 percent staking rewards and up to 12%, while the ecosystem holds 23%. Around 22% of the tokens go to the polygon foundation.

Since Matic tokens are technically being minted to reward stakers, it is technically inflationary. However, Matic does have a limited supply and soon they will be implementing their version of EIP 1559 which means that base transactions fees will effectively be burned, making Matic a deflationary token.

The extra transaction fees that users add to prioritize their transactions above the base fee will be enough to incentivize staking validators to keep doing their things.

Features of the polygon

Polygon combines the best of Ethereum's internet of blockchains and sovereign blockchains into an attractive feature set that is built by developers. For developers, It’s compatible, scalable, secured, and sovereign. These are the feature and attributes that polygon has an interpretive users' experience. The developer's experience is also optimistic and modular. That's high customizable extensibility and overall ability. Short time to market community collaboration is also the feature of the polygon. The major reason a lot of businesses choose to go for Polygon development is due to low gas prices and higher transaction speed.

Smart Contracts on Polygon

What are smart contracts?

A smart contract is basically just a computer program that can execute automatically and save transactions or agreements without the need for a trusted third party. They were first proposed in the 1990s by Nick Szabo. He used the analogy of a vending machine. You put money into the machine then it does one of a few predefined things. An example of one of those things is dispensing the item you selected. If you selected an out of stock, it will ask you to make a new selection and then repeat this process. It can just give your money back if requested or it can start dispensing. In all of these cases, the machine handles the entire transaction without the need for any third-party human interaction. Smart contracts are executed on distributed blockchains, most commonly on the Ethereum compatible blockchain but also available on other blockchains including Solana, polygon, Polkadot, Avalanche, Tezoz, Cardano, and more executing. These smart contracts on a distributed decentralized blockchain have also a number of benefits. You get some security transparency and variability in the execution of the smart contract. These contracts are also immutable and cannot be changed once they're deployed.

Smart contracts on polygon:

Polygon Matic is a layer two solution that is similar to the Ethereum Virtual Machine. This means you can deploy an Ethereum smart contract to the Polygon Network. Polygon promotes all the tools Ethereum consensus, smart contracts, and staking (instead of POW) for the native Matic token.

How to deploy smart contracts on polygon:

There will be a contract folder shown on your files and there will be access shown ''ownable.solidity''. A token of all these files and folders would be there. After the solidity contract, you need to go over to remix.Ethereum.org and then upload all of the files that you had downloaded over here as well. Because it’s time to deploy contracts now.

Just upload each and every file over here ownable.solidity and make sure you are uploading everything in the right order. The right order means that the access folder should be inside deployed contracts then the token folder. The erc721 folder should be inside the token and so on. Just make sure that you're uploading it properly. Now just go over to the compiler make sure that you’re on the right file which is like nft.solidity and compile it.

When you deploy smart contracts, you may need to change particular lines if you want to and then just compile on nft.solidity. Just make sure the compiler is set to 0.8.7 and not anything else. Now you are ready to deploy your solidity files. The particular notification would pop up and make sure you’re selecting the right account, the right network, and that you are connected to the remix. You also need some Matic in order to pay for the gas fees by using this method.

First, copy your wallet address and there you can see that get free Polygon paying for gas. So you need to go over this particular faucet, select Matic token, paste the address over here, press submit, and confirm it. It will be transferred in around one or two minutes, then go to the remix and fill up all details.

So, basically in the deploy part, you'd have to fill up the name of your NFT collection. To see the deployed contract, head over the Polygon scan and search for your contract. After this, all files and folders are uploaded, do verify them, and publish your contract.

Types of Dapps smart contract you can create on polygon:

Polygon is a decentralized application, Ethereum scaling platform that enables developers of the polygon to build scalable user-friendly decentralized applications with low transaction fees without ever sacrificing security.

Polygon has emerged as a leading platform facilitating the development of scalable Ethereum solutions and various decentralized networks. The polygon ecosystem keeps growing with multiple project partners and the latest tools introduced from time to time.

As of now, 300+ decentralized applications have been built on the ecosystem, and more projects are under development. With this scope in view, let’s explore the great tool and types of decentralized networks, on Polygon.

Scale your Polygon dApp projects with us

Rarible

It is an NFT marketplace. Rarible is working on a polygon integration. Rarible wants to become a multi-chain and allow for bridging with a few different chains. So this will be coming fairly quickly and you will be able to soon trade and makes polygon NFTs on the Rarible marketplace.

D-bridge

D bridge now supports polygon along with a few other chains. This is a cross-chain bridge so you can move your assets between Ethereum and BSc polygon to BSc polygon and so on. There are a lot of different bridges out there. Whether it be layer2 to layer2 bridges or Ethereum to Polygon like Umbria network. But these bridges are bringing more opportunities to easily access the different chains which are very important.

Our network metrics

If we check weekly net flows averaged over 93 million last month over the pos bridge more impressively, there are 38 times the number of depositors as withdrawals. Finally, network revenues have recovered back to 92k daily after the implementation of ERP-1559 when stabilized adjustments were made. So users are depositing into polygon 38 times more than users are withdrawing, which is a good sign that is telling us when users are entering Polygon they tend to stick around now and tokens deposits. You can bridge out using something else, as well but regardless 38x is certainly some good retention.

Quick Swap

It is a fantastic type of exchange where you can just like swap tokens on polygon without paying incredibly high fees as you would on the Ethereum compatible blockchains.

ParaSwap

It’s also a good decentralized exchange that will find the best token rates on the polygon. If someone wants to do a few trades and balance some tokens maybe look and see. If those tokens are available on polygon as it’s much cheaper to buy tokens on Polygon. If you only got a few funds maybe only a few hundred dollars then you can bridge your funds from wherever they are onto the Polygon blockchain. As you’ll be paying less than a cent per transaction and on platforms like ParaSwap, you will find the best possible rates. They don’t have the token yet so, maybe if you do a few swaps on the ParaSwap you might get an airdrop in the future.

Own race earn

On this Polygon platform, you can own some digital racehorses and race them against each other. There are different leader boards here, where you can earn cash prizes. You can also breed horses with other horses that are available for breeding.

SushiSwap

SushiSwap is available on many different chains. It’s available on Ethereum, Fantom, Avalanche, Polygon etc. They’ve got very great farms, where you can earn rewards. On SushiSwap, you can find some incredibly lucrative farms like Wrapped Eve, Eddie, or USDCB feeder paying 123 or 75 percent. But you can suffer permanent loss with these types of farms.

Aave.com

Unfortunately, the apps rates have gone down a bit but they're still decent. So at the moment, you will get 4.79 % for die with an additional 1.86 percent APR and you will receive 2.86 for USDC with an additional 1.3% apr per year. As compared to sushi swap the rates definitely have gone quite a bit lower.

BoneSwap

It’s a huge farmer that is pretty awesome and makes sure that you understand the risks with used farms. Also understands the risks behind the impermanent loss. So we don't recommend buying the token if you're not familiar with how your farming works the idea and would be to use from the token, which means earning the token and then selling it for maybe another coin that you want to hold like magic.

Auto Farm

A very popular yield farming aggregator. It’s available on the BSc Huawei chain and polygon. The cool thing about this app is you can go down below and you can look at the best-paying APR. These are super high pay probably a bit more risky projects or tokens with super high volatility. So, pWings might have high volatility compared to metrics. It’s compensated with having a super high APY of 21000.

Polycat Finance

The app got very awesome votes. When playing around with yield farms via that on Ethereum BSC or polygon. You should not buy the tokens of these youth farms as an investment because very often the Economics behind the yield farms means that the token loses value. So now it's at six dollars 16 cents and the last few days before it was at 45. In this app, you can click on the votes and look at the different pools that you can provide some tokens want and some of them are paying phenomenal rewards like a DFYN-WETH with a 217 percent pay. The risk is too high with these types of pools but it’s good to know that they exist.

Augury Finance

It’s also a super yield farming aggregator that contains different types of pools. The platform has a decentralized exchange. It’s got some very interesting strategies such as infusions that allow you to participate in liquidity pools and then pretty high APYs depending on the pool. They’ve got votes which is more or less the same thing and you can participate in some good stable coin. The pools such as USDC-miMATIC or UST-USTD offers 17 percent APY. They’ve also got some staking which is a single asset stake, allows you to lock up a single asset and this is actually pretty Lucrative. Especially if you want to earn some passive income. For example, on your Matic, you can earn 10 APY and six percent on your BTC. Just keep in mind when you put funds onto some default apps like this, you can lose all of your funds as a smart contract hacked or a rock pool happened where the dev runs away with their money.

Dfyn

It is a multichain automated market maker decentralized exchange. It is similar to QuickSwap and ParaSwap. They offer instant cashless transactions. They also are available on many different blockchains such as BSC, HEC, Avalanche, Polkadot, Algorand, and many more.

Benefits of our polygon dApps services

Polygon's mission is to offer a wide range of secure, fast, affordable, and energy-efficient Ethereum scaling and infrastructure solutions for developers to build decentralized applications. Here are a few benefits of our polygon decentralized applications services are.

Excellent design

Excellent design and higher throughput are hard to notice because it fits our needs so well. While mass adoption and poor design scream out its deficiencies. With finite developers, the Polygon can easily customize styles and symbols, add their elements, and scale the design. Following are the symbols that developers can combine to create multiple elements.

  • Icons
  • Symbols
  • Typography
  • Spacing
  • Components
  • Color gradients
  • Template for screens and pannels
  • Imagery
  • Buttons and elements
  • Design guidelines and principles

A design system is much more than just a collection of tools, a pattern library, and a style guide. It also includes abstract elements like value and shared beliefs.

Easy integration:

Over a million Coinbase new wallet providers, customers are using decentralized finance applications such as Uniswap, Compound, and Aave, and NFT platforms like OpenSea and Zora. However, there are often high transaction fees and long confirmation times. Users with smaller transactions can be priced out of being able to participate in the open financial system. This has made the need for convenient scaling solutions even more important.

Polygon network has recently emerged as one of the leading scaling solutions. This integration will allow for faster and cheaper transactions and provide easier access to the building dApps on Polygon.

We want to enable millions of more users to engage in the world of decentralized finance and decentralized applications. In the coming months, we’ll continue to take steps to make it easier for users to access and interact with a variety of Layer 2 networks both on mobile and the web.

Cross-chain functionality:

Polygon and polygon sovereign blockchains give cross-chain functionality. This means you can either simply transfer tokens from one network to another via bridge or perform a decentralized swap of tokens between networks to use any swap. Select your wallet network currently any swap platform supports 17 networks. After then you can connect your wallet to the application by clicking on connect to a wallet in the upper right corner. You can use a MetaMask or Coin98wallets. After switching the application to a new network any swap will automatically offer to edit and change the current network. Using any swap router you can transfer native that is not trapped tokens from one network to another via decentralized exchange. The tool is mainly used to transfer stable coins to use Anyswap router and select the source and target networks in applications. Select the token you will be transferring by finding it in the search bar and entering the amount immediately after that you will see the amount that you will receive in the target network fees. So, this is how polygon provided us with cross-chain opportunities.

Polygon’s MATIC is incredibly one of the fastest appreciating cryptocurrencies. MATIC tokens can be found over most well-known decentralized as well as centralized-based trading exchanges to be bought. Due to the solid features of Polygon, it is anticipated that MATIC is expected to be a good long-term investment option. As it allows to Polygon developers build their own unique scaling solutions in a quick and effective manner. The Ethereum Virtual Machine (EVM) compatibility mechanism in Polygon distinguishes itself from other Blockchains in terms of scaling, advanced flexibility, and interoperability for projects.

Till now, Polygon has seen an exponential amount of growth and it had been supported by various entities including major players in the DeFi ecosystem who in past supported Binance Smart Chain and Ethereum network.

“Polygon is an open-source Blockchain protocol scalability platform and framework for connecting and building blockchain networks compatible with the Ethereum network. Polygon traces its inception to Matic Network, which is an India-based network founded in October 2017 by Jayanti Kanani, Sandeep Nailwal, and Anurag Arjun — India’s first crypto billionaires.

Polygon was initially built to address the issues associated with Ethereum’s high gas fees and congested network. There is a decentralized, multidisciplinary team backing Polygon comprising Kanani as CEO, Mihailo Bjelic joined the company soon after it was rebranded to Polygon and became the fourth co-founder. Polygon as a decentralized network enables like-minded people and developers to contribute to Polygon development, where they create the vision of creating a borderless world.

Polygon is not an independent Blockchain platform, but it is a sidechain scaling solution, that strives to provide an interchain scalability solution that is intended to bring adaptability and scalability. Polygon functions as a parallel Blockchain running alongside the main Ethereum network to provide faster transactions and lower costs for users.

The Polygon functions upon the Proof-of-Stake (PoS) mechanism, which enables the Polygon chain operators to be stakers. Polygon development brings some of the best features of Ethereum Blockchain along with fast, low cost, and secured transactions that are possible on sidechains with finality.

MATIC is the native cryptocurrency of the Polygon network, which itself is a sidechain scaling solution. Polygon aims to bridge the gap among multiple scaling solutions and its Ethereum compatibility, and it brings out the best features of the Ethereum network without being slow and expensive.

The cost of adoption is quite lower in Polygon as it smartly contracts as a POS (Proof-of-Stake) framework. The native MATIC token is utilized for exchange payments in the Polygon network. As a cryptocurrency MATIC has a great potential for growth. There is an increase in demand for NFTs and more DeFi projects are developed by Polygon developers.

MATIC is certainly a good investment if you are looking to invest in cryptocurrencies, as it is one of the fastest appreciating cryptocurrencies. MATIC is the native cryptocurrency of the Polygon network that can be found over the most well-known decentralized as well as centralized-based trading exchanges to be bought. MATIC has the backing of the solid features of Polygon and, many experts are of the opinion that MATIC is suitable for those who are looking for a good long-term investment option. MATIC lets Polygon developers build their own unique scaling solutions in a quick and effective manner.

Till now, Polygon has seen an exponential amount of growth and it had been supported by various entities including major players in the DeFi ecosystem who in past supported Binance Smart Chain and Ethereum network.

Formerly Matic network, now known as Polygon works to improve the functionality of the Ethereum network by Commit chains. Polygon was developed as a Layer-2 scaling solution to bring mass adoption to the Ethereum network. Polygon network as an interoperability solution functions on the Proof-of-Stake (PoS) consensus mechanism where developers are expected to use the Matic network. The Matic network solves many problems by building a decentralized platform with the help of an adapted version of the Plasma framework. This network framework with finality on the main chain can provide solutions to the Polygon developers to build dApps that will be faster and function at an extremely low cost.
