It is a collective failure of our community that we kept using ERC-20 and its silly allowance mechanism.

The Pioneer's Dilemma The impossibility of distinguishing true novelty from failed repetition. As an entrepreneur, you can't know whether something failed because it’s fundamentally flawed—or because no one has done it properly, or at all, before.

Are there any EVM chains that do NOT use the standard ETH denominations (wei, gwei, szabo, etc.)?

It'd be pretty cool if Chainlink offered a user-defined value type for their 8-decimal price feeds. Similar to how PRBMath offers UD60x18 and SD59x18.

I wrote this little Git helper called `git done`: 1. You're on the feature branch `feat/foo` 2. The PR for `feat/foo` has been merged into `main` 3. With the alias below, running `git done` will: Switch back to main. Pull the latest changes. Delete `feat/foo` locally.

If a web3 product deploys smart contracts for users, but those contracts are not open-source, there's zero accountability. Neither customers nor the broader public can verify whether there have been any bugs in those contracts.

If your product doesn’t make it easy for users to request features or suggest improvements, you’re leaving a goldmine of feedback on the table.

I just found out about Biome — a dev tool that is both a formatter and a linter. Bye, bye ESLint + Prettier setup 👋😊

Some chains (e.g., Polygon) created a 'dual' ERC-20 representation of their native token (e.g., POL) to avoid a separate wrapper contract (e.g., WPOL). Bad idea. It's an unsafe design and it will 100% lead to exploits.

I wish I had Claude 3.7 when I started coding 12 years ago. It would’ve saved me so many hours of debugging.

I didn't expect Base (the L2) to grow so much. A nice success story of an 'inside' startup created within a larger company.
