QuickSwap lets customers keep away from Ethereum transaction charges with Polygon


As Ethereum gasoline costs rise, the chain that impressed Web3 is turning into gentrified, with excessive transaction prices pushing much less rich customers onto competing blockchains or scaling options. Which means many use circumstances have gotten unfeasible within the proverbial layer-one downtown, and suburban neighborhoods are being developed to permit for a cheap layer-two blockchain expertise. 

Since getting acquainted with Polygon across the time of its launch in late 2019, Sameep Singhania has been an avid supporter of tasks constructed on the protocol. In 2021, he created QuickSwap, a decentralized alternate (DEX) serving the wants of the budding Polygon ecosystem.

Singhania left a promising profession as a software program developer in 2017 to work as a contract developer, solely to search out himself writing code for an array of blockchain tasks within the DeFi and layer-two sector. Among the many many tasks he labored on, he spent 18 months with blockchain e-commerce website OpenBazaar, and served as lead developer for DeFi alternate ParaSwap.

Polygon is one layer-two answer constructed on Ethereum, and it provides customers decrease charges when transacting on-chain. QuickSwap is Polygon’s main DEX and capabilities as a coronary heart of the community. 





A DEX for Polygon

After engaged on maybe dozens of tasks on Polygon from 2019 onward, Singhania “realized that to develop the Polygon ecosystem, we want a DEX.” 

This was as a result of whereas “99% of blockchain tasks have a token,” listings on in style exchanges are usually not straightforward to rearrange, and plenty of customers are usually not keen to create an account at an obscure alternate simply to commerce a specific token that’s not listed elsewhere. A DEX can operate because the central market sq. of a blockchain community, giving its customers entry to all the things they want with out having to enterprise to a different chain.

Singhania remembers being inspired to create a DEX by Polygon’s co-founder, Sandeep Nailwal, who put him in contact with Roc Zacharias, a marketer with Lunar Digital Belongings. “That’s how we arrange a group — we had builders, we had a advertising and marketing group, an ideal combine, and we launched the app,” he explains.

Polygon — beforehand known as Matic Community, with MATIC remaining its ticker — is a layer-two blockchain. Meaning it’s a blockchain constructed on prime of an present chain. Whereas Lighting is an instance of a layer-two, or L2, constructed on Bitcoin, Polygon is constructed upon Ethereum. Consequently, Polygon-based tokens might be despatched to Ethereum addresses, whose customers can retrieve them just by switching to the Polygon community on a DApp resembling MetaMask.

The oft-stated benefit of L2 options is that they’re extra nimble than their behemoth dad and mom, permitting for quicker and cheaper transactions. With Bitcoin transactions costing over $10 and taking roughly 10 minutes for the primary of six confirmations, it’s clear that transacting on the mum or dad chain shouldn’t be sensible for on a regular basis transactions in El Salvador, for instance, the place laborers can earn as little as $100 per 30 days. As a substitute, Salvadorans use Bitcoin Lighting, whose transactions price as little as 1 satoshi.

The transaction prices on the Ethereum community are a lot larger, making it “unusable by the small customers” who’re successfully priced out of utilizing DeFi options or decentralized exchanges like Uniswap. In January 2021, a “regular Ethereum transaction on Uniswap price round $100,” Singhania remembers.

“If I’m a traditional consumer and I wish to do a small commerce, I can’t do it on Ethereum — the common transaction dimension on Uniswap is someplace round $50,000.”

“Polygon is there to scale Ethereum,” Singhania says, which has its execs and cons. He additional explains that whereas “Ethereum is probably the most safe answer on the market,” it comes at the price of excessive gasoline charges and comparatively sluggish transaction occasions.

That’s not precisely fascinating for an financial system — smaller denominations of foreign money exist as a result of not all the things might be performed with $100 payments. L2s are the reply for permitting smaller transactions on present networks like Bitcoin and Ethereum. On Polygon, customers can alternate Ethereum-based tokens, NFTs, and work together with sensible contracts cheaply. 





The urgent want for L2s is comparatively new, as a result of transaction prices have risen considerably previously two years together with the blockchain consumer base. On QuickSwap, transactions between the over 23,000 obtainable pairs price only some cents. “You may principally use QuickSwap to commerce any ERC-20 token which has liquidity and exists on the Polygon community,” Singhania says. Charges are naturally paid in MATIC.

Contemplating the financial savings, switching digital belongings from Ethereum to Polygon looks as if an apparent answer for a lot of customers. Nevertheless, some actions, just like the buying and selling of six-figure NFTs, stay decisively away from the Polygonian suburb. Equally, Singhania acknowledges that these making million-dollar trades have much less to realize from Polygon. 





There are two main methods to maneuver belongings to Polygon, based on Singhania: alternate withdrawals and bridges. “Quite a lot of massive exchanges like Binance help deposits and withdrawals on the Polygon community,” which implies that the Ethereum community can doubtlessly be prevented completely. As for belongings already on Ethereum as an alternative of on a centralized alternate, they are often bridged, which is successfully an inter-blockchain switch.

“Each L1 and L2 functions have their very own execs and cons and so they each have their use circumstances — now it’s as much as the consumer to decide on which platform higher fits their wants”

Studying the ropes

Singhania, 31, grew up in India’s capital, New Delhi. He had an early ardour for coding since highschool, describing the method of coding “like magic taking place,” whereby “great stuff” could possibly be created with only a few strains of code. He adopted his ardour in 2008 to JSS Academy of Technical Training, on the outskirts of the capital, the place he accomplished a bachelor in pc science and served as a campus IBM Ambassador.

Graduating in 2013, he started his profession in software program testing and automation at Dell, however quickly realized that he needed to “focus extra on improvement” as an alternative of remaining a software program tester, a task with much less alternatives for inventive enter, for the rest of his profession. He made the change to software program developer in 2015 at Drishti-soft Options, the place he labored on customer support software program and arranged net improvement coaching classes.





Nonetheless not fairly settled within the position and looking for “one thing the place I don’t get bored,” Singhania converted to software program freelancing in 2017. “While you do freelancing, you get to know lots of people and study a variety of new industries and domains,” he remembers, noting that he was lastly curious about his work. One in every of these new industries was blockchain, which he had beforehand heard about whereas working as a developer. 

“I once more got here throughout this blockchain and Bitcoin stuff whereas trying to find a venture, so I made a decision to present it some extra time and do some extra analysis — to determine ‘what is that this Bitcoin? What is that this blockchain?’”

By mid-2018, Singhania was a full-time blockchain engineer for various tasks, together with Akila Labs, Bitgrit, and Toptal, the place he developed ERC-20 tokens and sensible contracts for issues like airdrops, token vesting and crowdsales. Notable amongst this was 18 months spent working with the decentralized market startup OpenBazaar, “which was attempting to construct one thing similar to Amazon — however on blockchain” utilizing the peer-to-peer InterPlanetary File System (IPFS), Singhania remembers with pleasure.





Compounding data

“When DeFi was simply beginning” in 2018, Singhania labored because the lead developer and first worker of ParaSwap, an aggregator DApp which brings collectively a number of DEXs in order that customers can seamlessly commerce cryptocurrency pairs which don’t exist collectively on any alternate. All of this buying and selling is completed by way of Singhania’s sensible contracts, which “deal with thousands and thousands of {dollars} on a regular basis,” he says proudly, including that the platform noticed 3.3 billion {dollars} in quantity previously month.

“That venture allowed me to make an entry into DeFi — it principally launched me to all the things on the market like Uniswap, Bancor, Kyber Community, as a result of to construct ParaSwap we would have liked to be taught all the things about DeFi.”

With DeFi below his belt, Singhania encountered layer-two blockchain options whereas engaged on a cube recreation for one among his purchasers, a blockchain on line casino.

He quickly realized that “it was too costly to do it on Ethereum” — despite the fact that 2019 gasoline charges had been a fraction of what they’re right this moment. One thing new was wanted, and Singhania “began exploring for layer-two options,” he recounts. He first constructed his cube recreation on the now defunct layer-one Loom Community which shut down shortly thereafter, Singhania scouted out Matic Community, which was in late 2019 “very new and their mainnet was not launched.” Working with the Matic Community group, now known as Polygon, Singhania acquired the cube recreation up and working, turning into acquainted with the Polygon community within the course of.

Ethereum cube video games are usually not the primary to undergo from scaling points. Erik Voorhees’ SatoshiDICE, for instance, was launched in 2012 and shortly accounted for over half of Bitcoin transactions. With transaction costs rising, making small on-chain bets on Bitcoin’s fundamental layer has since develop into impractical.





Onboarding the subsequent technology

Now that Polygon is a low-cost choice to L1 and has a dependable DEX, Singhania believes that the subsequent step in scaling the layer is to enhance the consumer expertise to be able to make it user-friendly for thousands and thousands of people who find themselves new to cryptocurrency. As QuickSwap is a central level of the Polygon ecosystem, a lot of the duty falls to his shoulders.

“The way in which that issues are designed proper now, it’s not for a novice —  it’s for a well-trained crypto consumer.”

In Singhania’s view, the value of MATIC might be anticipated to comply with the adoption of the Polygon layer. If the group continues to execute, “it’s only a matter of time” as to when costs would possibly start a gentle climb. One factor is evident: Singhania is not bored along with his work and is “not doing any sort of freelancing as a result of I don’t have time.”
