Very noobie here. I'm sorry,
Does anybody know what happens on OpenSea when you actually CREATE an item?
I know it doesn't mint one but what it does? (As it signs a transaction tho).
I've been trying for weeks to understand the "gasless" proxy thing they have but I don't know how they actually transfer an NFT to your Wallet, even if it's not minted.
I also managed to deploy and mint a Creature with the example contract (open sea creatures, https://github.com/ProjectOpenSea/opensea-creatures) but how can I let Users mint their own item on this factory contract?

I am making a smart contract and want to know the bitcoin balance of a metamask address.How can I do this? Since BTC is not ERC-20.
Have you considered using a block explorer (something like blockstream.info)
All you need to know is the address you want to query.
I assume want to do automate this, and in this case you can search for an api - http://blockchain.info/api
You will have to implement the API, but that's the only way as far as I know from a smart contract running on Etherium.
It's a music website, the idea is to record on the blockchain every time a song is played.
Since we don't want to force users to install metamask so they can sign transactions, the idea is to store in an array, so that the smart contract sends it to the blockchain every 100 plays for example.
What's the best way to achieve this?
Please explain better, what technology do you use for your website? .net asp?
when you say "send to the blockchain" do you mean to a smart contract?
and an array of what do you want to send?
If you want to send something from a website to a smart contract on the blockchain you can use Nethereum thru .net asp.
Shouldn't be hard to write a c# code to send something every X times.
Just remember that storing new data on the blockchain cost gas (money).
I am trying to see if there is any way to create a smart contract and deploy a Rinkeby test faucet from scratch. I could not find any tutorial talking about this! Does anyone have an idea of the technology behind creating such a faucet, for example, https://rinkebyfaucet.com/ or https://faucets.chain.link/rinkeby ? How do these companies develop their Rinkeby fauces, and do they pay actual money when they send us 0.1 ETH?
Hi super basic question as I am new to NFT dev (currently learning solidity). Looking to make a super basic NFT project with website, art, and link to Opensea in secondary market (no roadmap, just a learning experience for me and probably giving NFTs for free). I understand that you can make a candy machine that allows users to mint on website, but I'd like them to be able to view and trade their nfts on a secondary marketplace like Opensea. How would I go about doing this? Thanks.
After minting nfts, they can be view and trade on Opensea and do not need additional actions.
As stated before, you don't need to do anything to actually have them in Opensea, except to deploy your SC.
I think this could be very useful to you https://buildspace.so/p/mint-nft-collection if you are just beginning and new. It's a well explained tutorial, and you can see there how this would work for you to see it in opensea.
Hope that helps.
University is out for summer and I am attempting to develop a smart contract on binance smart chain.
I have followed a youtube tutorial and made a very basic token which allows buys and sells, however I would like to add a burn function i.e a tax is placed on every transaction, and I would like x% to be added to liquidity on pancakeswap, x% to be burned and x% to be redistributed to holders of my token.
The internet seems to be pretty scarce on information on how to implement this, so if anyone would mind giving me a hand it would be great!
I am creating the token on remix.ethereum.org
