Stake DAO partners with Alchemy to power user-friendly DeFi applications.

Even for seasoned crypto enthusiasts, DeFi can seem overwhelming. The sheer number of options seem to be growing by the hour. Some platforms have worked hard to make their user experience (UX) simple, but other more experimental platforms are only accessible to the most daring of savers and investors. To make things even more daunting, maximizing DeFi income can be a full-time job in and of itself due to the constantly shifting landscape of offers, opportunities, and risks.

This is why the creators of Stake DAO, a non-custodial DeFi platform built on Ethereum, decided to launch their service in early…

Yesterday marked my 1 year anniversary working full time at Alchemy.

With this milestone, I thought I’d take time to reflect and share my thoughts on why there isn’t a single job that I’d choose over the one I have right now.

I know, that’s a pretty absurd statement, but I truly feel that way and I’ll tell you why.

It’s hard to condense all the things I love about working at Alchemy into one piece, but when I boil it down, it really reduces to 3 primary factors: the people, the impact, and the mission.

1. The People

My co-workers are friends…

What are Internal Transactions?

To understand what internal transactions are, it’s helpful to take a step back and look at the types of transactions we have on Ethereum. Transactions are state changes to the Ethereum chain, meaning they aren’t reading data, they are writing data to the chain.

There are a handful of state changes that…
