cmp.setup({
  ...other stuff
  preselect = cmp.PreselectMode.None,

  })
})

ERC4337 Account Abstraction is a significant development for Ethereum and EVM-compatible chains. What's remarkable is that it's already live for developers and didn't necessitate any changes to Ethereum's core protocol. So, what's changing?

I asked ChatGPT to explain the blockchain using a candy store as an example and this is what it said. I think it's pretty good! These kind of prompts could be helpful for newcomers to understand blockchain and other complex technical topics.

The cashier then creates a "transaction" that records the details of the purchase, including the type and quantity of candy that you're buying, the price, and the date and time.

*The transaction is then added to your "ledger," which is a record of all of the transactions that

Browser wallets have long been discouraged in this sub, but I think the risks are blown way out of proportion. Here are some myths about browser/mobile wallets like Metamask, Coinbase, and Rainbow wallet:
