Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

I turned my open-source project into a full-time business
Plenty of projects are source-available, but not open source, and get tons of issues, and even contributions (https://github.com/MetaMask/metamask-extension off the top of my head)

Understand Attestations! Ultimate Guide📚
You can create an attestation based on an existing schema or create your own. Schemas define the format in which attestations will be made, and in this case, we will use the Is Human schema to attest that the owner of a certain address is human. For this example, you only need to connect your Metamask wallet (or any wallet) to Scroll Sepolia, then enter the address you want to attest and click Make attestation. You can choose whether you want the off-chain attestation, i.e., free, obtained only by signing a transaction. Alternatively, you can choose to make it on-chain and pay for the transaction to make it public and connect it to smart contract logic. In this case, you will need to obtain funds in Scroll Sepolia through a Scroll Sepolia Faucet.

Fe or Solidity, which is better?
For this tutorial you will need Metamask or other wallet of your choice, with Scroll Sepolia funds that you can get from a Sepolia faucet and then bridge them to L2 using the Scroll Sepolia bridge. Alternatively, you can use a Scroll Sepolia Faucet to get funds directly on L2.

Why Bother with uBlock Being Blocked in Chrome? Time to Switch to Firefox
> I get a 3-5 sec lag on launch [0] as it prepares the browser to block ads.
uBO is typically ready in a fraction of second, so "3-5 sec" is not normal. In Firefox all extensions sit in the same process, so it's possible another extension is preventing uBO to be ready in a timely manner, this has happened[1].

Optimize Your Web3 DevOps with User Feedback Forms
That’s where the Form xChange open source tool comes in. It gives you the ability to easily create and use feedback forms on Web3. And it’s pretty easy to implement and use. The solution connects to a MetaMask wallet (which users most likely already have) and allows application users to vote anonymously using one or more forms — with each form allowing for multiple questions.

Blockchain transactions decoding: making wallet activity understandable
Lets look the events of Open Zeppelin’s ERC20 token contract:

I get an "ambiguous primary types or unused types" error when trying to mint an NFT requiring 2 signatures via EIP712
I modified my code to use EIP712 to require an authorized wallet to also sign in order for an NFT to be minted. I based this off of this: https://github.com/OpenZeppelin/openzeppelin-contracts/blob/7e814a3074baa921db584c180ff6e300cdec8735/contracts/token/ERC20/extensions/ERC20Permit.sol. This is an example of someone calling a smart contract containing this ERC20Permit.sol code https://github.com/Uniswap/v3-periphery/blob/main/test/shared/permit.ts. This particular ERC20Permit.sol code is designed to allow an account to approve ERC20 spend limits without spending gas fees but the same underlying mechanisms could be applied to my use case.

What is the current best practice for badges / soulbound / nontransferrable tokens?
In the next step of my journey, I went to Github to see what other people were building. I didn't fine much. My heros [OpenZeppelin](https://github.com/OpenZeppelin/openzeppelin-contracts/tree/master/contracts/interfaces) don't seem to have any examples in their repository. Github's search yielded no results. Some Google searches finally did land me on two repositories. One is [an implementation of ERC-5114](https://github.com/TeamSHARKZ/soulbound) - horray!. The other one one of those traditional [awesome lists](https://github.com/attestate/awesome-soulbound-tokens). Great resource and introduced me to a standard I previously missed, [ERC-4973](https://eips.ethereum.org/EIPS/eip-4973). Of course, having completely missed a token reinforced how easy it is to miss something obvious along the way and encourages me to reach out and ask the community for more information.

Now create a folder named IERC20.sol inside your contracts folder and paste the following code into it. This is the ERC20 interface we will need to interact with the USDC contract. You can also find this code here

Generating Decentralized identifier using ERC725 and ERC735
You're trying to import a markdown (text) file that describes the ERC721 spec, not an actual ERC721 compliant smart contract. I believe what you're trying to import is https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC721/ERC721.sol

Question about implementing a UUPS proxy
Look at TransparentUpgradeableProxy.sol, but the actual delegation happens in one of the contracts it inherits: Proxy.sol.

A look into formal verification of smart contracts using Certora
Let's grab some examples from OpenZeppelin's TimelockController spec. In a Timelock, operations can have different states. We can write a rule that checks, for instance, that calling execute is the only way for moving an operation from ready to done state.
