KozukiOdenGas Prices & Nonces
If you have interacted with a smart contract on Ethereum Mainnet, you have probably heard of gas or had to pay gas for your transaction. Gas is typically measured in gwei. Demand for block space on Ethereum Mainnet currently outpaces its supply, so the richest users tend to pay a premium to put their transactions through first. Many believe this will likely be an end-state for many of the monolithic blockchains existing today that claim to solve scaling. Block space will continue to be a prem...
KozukiOdenHow to create a token URI
Creating an NFT using the ERC721 standard means that the token created also needs a token URI Things you’ll need. This list is not extensive and will depend on how much metadata you want your token to haveThe image fileThe image nameThe image descriptionAn IPFS path for the image e.g. ipfs://QmVDae8m3X6HZf9v2Jnyqe53Xpj64vEvQDUci1NpX1KrcsThe first thing you’ll need to do is upload the image to an IPFS node. You can create a pinata account to do this. Once the image is uploaded and pinned on Pi...
KozukiOdenHow to 'backup' your NFT
While a blockchain can cryptographically prove which address a token belongs to, if this token represents a digital image then it is likely the file displayed is stored on a server that may not have/keep having the data availability of a mature, socially distributed blockchain.Punk 8694 File URLTo prevent losing this image due to unforeseen reasons the simplest way would just be to right-click + save to your computer. Another way would be to also setup an IPFS node and pin the images. To do t...

A typical Ethereum Classic web application has two main parts. The first is the client side which is what you see when the website loads in a browser. The other is the back end or server side which is typically written in solidity and lives on the blockchain.
There are two ways I know of that you can interact with a smart contract on Ethereum Classic without the client side.
The First - Blockscout
In blockscout find the contract address for the application and then go to the write section of the contract address e.g. the write section of this NFT smart contract. All of the write functions available on the client side will be accessible.
The Second - MyEtherWallet
You can also interact with the smart contract using its ABI and the contract address. To do this:
Connect your Ethereum Classic wallet to myetherwallet
Go to the contract section and click on interact with contract
Enter the smart contracts ABI and contract address
On the next screen you will have access to all the available write functions in the smart contract
