A place for talking about the Ethereum Virtual Machine on Farcaster.

With the advent of L2s, by far, the most common issue in dApps is lack of chainId check in transactions.

If you are authoring a dApp, make everyone a favour and *always add chainId* to all transactions you are initiating.

For instance in Wagmi: https://wagmi.sh/core/api/actions/writeContract#chainid

Cryptoartist focusing on dynamic and fully on-chain artworks.

Tweets are not financial advice.

Pronouns: they/them

When chainId is set, wallets will not allow you to sign and complete a transaction in wrong network

Without chainId, nothing prevents that

Could make a difference between someone keeping and losing thousands of dollars by sending a tx in wrong network
