Are RPCs generally safe?
I don't care if my transaction is leaked as long as my secret phrases are safe. Is it possible to leak your SP through a RPC? For example, there are many RPCs on https://chainlist.org/ And they have a security score for each one. Should I be worried about a low score?

So I accidentally sent USDC over the Optimisim network instead of the Eth network, is there anything i can do to get it back?
3: You now need to add the Optimism network into Metamask. Go to chainlist.org, "connect wallet" (connect with Metamask), search for Optimism, click add to Metamask, approve, switch network. You'll now be on optimism.

Is Ethereum's network traffic fully centralized, or am I wrong?
Infura provides what's called an RPC endpoint. RPC is the way you expose a node to people who want to talk to it from a web browser etc. You can run your own node, using a normal computer, but it needs a big SSD drive (around 2TB) which costs a couple of hundred dollars. If you want to use a node hosted by somebody else, there are lots of other companies providing them. A good one is Alchemy. You can see a long list of publicly available RPC nodes for Ethereum (and also similar lists for other chains) at https://chainlist.org/

Build an AI-powered NFT generator with TS, GPT, Polygon and CASE (Part 1/2)
That's it for the first part ! Then we will use Hardhat to deploy our Solidity Contract on the Polygon testnet, and then overload our mintNFT() function with the actual minting. If you want to see the Part 2 quickly, give us some love and we will execute ! ❤️❤️❤️

Upgradeable smart contracts
To keep things simple and visible (in case you cant deploy), we will use Sepolia testnet blockchain and Hardhat as development environment, so to configure hardhat to use sepolia we need to add the following configuration to the hardhat.config.js file:

How do I deploy an ethereum contract with hardhat and my Trezor wallet?
The documentation has no mention of Trezor wallet support. According to this GitHub issue I could try out this Frame application, but I was wondering if there was a simpler solution that didn't require installing some 3rd party application.

Advancing dApp development with Hardhat Indexing: A Game-Changer for Ethereum Devs
The hardhat-ethers plugin adds the ethers.js library to the Hardhat node, making it possible to use its functionalities. It's possible to use it to deploy the contract, but since our goal is to create transactions, we can also add some code to do that as well.
