https://weekinethereum.substack.com/p/listen-to-evans-new-podcast-and-win

I’ve started a podcast: Week in Ethereum News web3 Builders. Let’s cut to the chase: podcasts are a game of accumulating subscribers. New podcasts don’t have them so…it’s giveaway time!

So I’m doing two giveaways. You can enter both.

To win 1 Ether:

1. Email web3builders@protonmail.com and put IN THE SUBJECT what Austin Griffith thinks is the worst part of building in web3. There are several acceptable answers and will be obvious if you listen to the show. You’ll be subscribed to our Substack to get new show notifications – though you can always unsubscribe after you win.

2. RT or quotetweet:

   https://www.twitter.com/web3builderspod/status/1691145997076803584

3. Follow @web3builderspod on Twitter.

To win the Lattice1 (the best hardware wallet in crypto!):

1. Email web3builders@protonmail.com with the name of the US cell phone carrier that you absolutely must avoid if you don’t want to get sim swapped. (The answer is in the last episode)

2. RT or quotetweet:

   https://twitter.com/web3builderspod/status/1690445780492914688

3. Follow @web3builderspod on Twitter.

That’s it. I realize you may dislike the giveaway element of it, but if have you appreciated 7 years of Week in Ethereum, could you do me a favor and retweet as well as subscribe on Apple, Spotify or RSS?

I’ll be looking through to see who RTd, I hope to see you on there. 🙏🏻🙏🏻🙏🏻

Thanks,

Evan
