How to deploy Smart Contract to Polygon/Matic Chain or any Ethereum based chain

[@SumeetChawla]

Wah! What timing. I just wrote my first contract on ETH and my next step was to deploy it on Polygon chain 😂😂 🔥🔥🔥

[@SumeetChawla]

Quick question: Where did you configure the deploy method to deploy on matic chain? How does it know that by default it is supposed to deploy on Polygon?

[@Web3_Club]

Because metamask is connected to polygon, so it sends transaction to polygon

[@SumeetChawla]

@@Web3_Club ah! D'uh 🤦🏻‍♂️ That was simple. 😂

[@kurtpluto7201]

hey bro, did you figure out how to transplant eth smart contract to ploygon?

[@SumeetChawla]

@@kurtpluto7201 As Shobhit said above, you just choose web 3 injected in remix and deploy it to the current network you are selected in metamask. If you are using hardhat, you need to configure your hardhat config for the respective network and use it while deploying the contract

[@boringdevjs]

Amazing Tutorial bruh!!!! finally saw a real working example.

[@mooot768]

Dude seriously you’re so generous for sharing all of this, thanks. Can I ask you please to post a video about deploying ERC721 upgradable contract on polygon, thanks in advance 🙌

[@pradyumncs]

yesss is this possible

[@agr_]

This is extremely helpful. Thank you for creating this video! Goodbye gas fees!!!

[@astronotyet]

Great explanation! Just an fyi, you don't have to initialize the int variable to 0. In solidity all state variables are assigned a default value(the default value for a bool is false. The default value for the uint or int types is 0)

[@Web3_Club]

Yes, you are right, I was just making sure 😅

[@Andrembramwell]

do you know how to connect to local host 800 on windows 10?

[@SuperSaiyanT]

Hi Shobhit, this is a great video and so are your other ones. I'm a complete newbie to programming in general and cannot thank you enough for the content you're uploading! I am working through this video and have come across an error which says that Metamask no longer injects web3. Going through the Metamask documentation, it says that window.web3 has been replaced window.ethereum and ethereum.request. I was wondering if you can help by telling us what needs to be replaced in your coding above for it to work with the latest changes? Thanks!!

[@WebDevCody]

How does this code potentially change with the erc1559 change? Do you have to provide different arguments to your send cal? How do you estimate the gas price with this change?

Cool video. Buy man you live in the jungle or something ? Those bird noises 😅

please how will i open sublime text on remix widows 10 i really don't know how you did it

[@sam_making_games]

Could you please create a repo on Git and paste the link in the description? Saves time for the peeps just looking to get the pre-written code.

I try to do a polygon arbitrage trading bot in javascript, that can trade on uniswap, sushiswap, quickswap and so on. Do I need a smart contract? If I want to add a flashloan, does it change anything? Thanks!

while trying to deploy meta mask transaction a error popped up "Uncaught ReferenceError: deploy is not defined at :1:1"

You haven't written the deploy function

Is there a smart contract for polygon 1150 eth on opensea where we can create for ppl to claim their own tokens ?

[@TheDoktorot]

What is the difference in code deploying to polygon vs ethereum ? What is the difference in writing contracts for polygon vs ethereum?

[@Web3_Club]

There is none

[@Oneofonebrand]

Running into an “Uncaught Reference Error: Web3 is not defined at :1:1 error when trying to input “Web3 into the console any idea why this may be? I’ve followed your steps exactly yet keep getting an error.

[@Web3_Club]

Web3 library URL might have changed, refer to their documentation.

God bless you for this

How are you opening console in the localhost server? Anyone?

Hi bro but where to upload the nfts file 🙄bro I have 10 k images to ulpoad using polygon matic

[@Andrembramwell]

do you know how to connect to local host 800 on windows 10?

[@RA-hb9jw]

how people buy your token after you deploy it?, I believe uniswap dosn't accept matic network

[@Web3_Club]

There are other exchanges on matic network, like quickswap, sushiswap, etc.

[@elblogdejoelrizos]

Hi, thanks for the tutorial, but I do not understand something... What I see is that you are deploying under Ethereum... so what Polygon is??? I mean, you are following the same steps for deploy to Ethereum, so I do not understand the difference with deploying over Polygon.

[@Web3_Club]

The network that Metamask is connected to, that's the network where we deploy our code. Polygon and Ethereum have same virtual machine (EVM) so same code works on them

[@elblogdejoelrizos]

@@Web3_Club aham ok. Deploy or transactions over Polygon are free?

[@Web3_Club]

@@elblogdejoelrizos Of course not. You have to pay gas on polygon, which is cheaper but not free

[@elblogdejoelrizos]

@@Web3_Club OK thanks!

[@elblogdejoelrizos]

@@Web3_Club Do you know any ethereum blockchain platform compatible with free gas for deployment and transactions?

Hi, can you help me? I deployed a smart contract to Polygon chain for my NFT collection, I used remix.ethereum. Now the contract is verified and it works well but I want to change the mint price. How can I do it, can you help me? If I change the price only on the Minting Dapp and mint an NFT with a different price of the smart contract it will fail. I don't know how to modify :(

[@Web3_Club]

Did you add a method to change price?

[@SagarGopale9989]

First of all great tutorial. I have a query though. How can you automate acquiring the abi and bytecode process? I mean copying and pasting is fine in tutorial but cant I get it through code?

[@Web3_Club]

Checkout truffle, it provides tools to do this via cli

[@bitcoinroc3020]

Hi, how much does it cost to deploy 10000 nfts on polygon ?

Hi shobbit , i have a message error when i try to deploy(abi, bytecode) : "Uncaught ReferenceError: account is not defined ; at deploy ; at async :1:1 ". Can you help me ? Thank for the video and your respons you help me a lot !

You don't have any value in account variable

@@Web3_Club Okay thank you, but how can i add value to the account variable ? Sorry for all this question but i’m really want to learn. Thank you for your time.

LOVE YOUR CHANNEL! Hey, can you please share if there is any way to purchase matic or any crypto using Fiat, outside of exchanges like WazirX or Binance? Transak has temporarily banned INR. Thanks in advance!

[@kingbandz5390]

Do you have a email so people can get in touch with you to be able to develop smart contracts polygon Network

[@MrMarcoone23]

Thanks a lot for this video. I managed to write my first working NFT minting dapp on Rinkeby and you made things way easier to understand. I set the minting price to 0.01 ether but I want it to be available only on Polygon to have it 100% live and save on gas fees, so what do I need to do to charge users WETH instead of ETH? Is this process handled automatically when the smart contract is deployed to poligon?

[@Web3_Club]

ETH is actually the native token of chain, so on polygon, accepting ETH means you're minting with MATIC

[@MrMarcoone23]
