Isolating Crypto Assets and Access
For the last couple of years I’ve done all of my Ethereum activities using my thingelstad.eth address with the associated identity. I’ve used this for storing value, holding NFTs, collecting POAPs, and everything else. I decided that it was time to create some isolation of access and identity.
I’m still using thingelstad.eth as my primary address and means of authenticating with various services. It also holds a number of my NFTs and crypto assets. But I’ve also now created two activity-specific addresses.
mint.thingelstad.eth is the address that I’m using specifically just to mint NFTs. When you mint NFTs you have to authenticate with a new smart contract and usually provide some form of limited access to your assets. By using a dedicated address just for minting I can limit the risk of a malicious smart contract.
vault.thingelstad.eth is the reverse of the minting address. This address is specifically to hold NFTs or other assets that I have no intent of selling or transferring. This address will never be used to authenticate to any website. All activities here will be done using wallet transfers.
Additionally, I decided to create some specific addresses for applications that I use a lot. This was inspired in part from Vitalik’s conclusion:
That said, it is my view that wallets should start moving toward a more natively multi-address model (eg. creating a new address for each application you interact with could be one option) for other privacy-related reasons as well.
I love the idea of wallets automatically associating a unique address with each application. I do this today by using a masked email addresses with Fastmail and passwords managed by 1Password.
ens.thingelstad.eth is the address I’m using to hold my Ethereum Name Service registrations. ENS has built in capability for one address to register a name, and the control of that name to be delegated. So all of my 21 registered ENS names are now owned by this address, and control of them is delegated to thingelstad.eth. The only app that will ever connect to this address is ENS itself, which protects my name registrations from malicious actors.
POAP.thingelstad.eth is an address I’ve made just for collecting POAP tokens. I currently hold 90 different POAP tokens in this address. This allows me to have a specific identity and address just for POAP usage. Most activity for this address is on Gnosis Chain since that is what POAP uses natively.
niftyink.thingelstad.eth is an address just for using Nifty Ink. I’ve collected 736 “inks” on this site and now I have them isolated into an address that I only use for that purpose. 🤩 This is again a way to limit access from a malicious smart contract.
Technically I also have reddit.thingelstad.eth but was created by necessity since Reddit Vaults are managed differently. However, it serves the same pattern as the other application specific addresses.
We went on a tour of St. Olaf today as Mazie works through her decisions on where she wants to go to college. It is a really pretty campus.
Nordic Village at Riva Terrace
Tammy and I enjoyed a delicious 7-course Nordic Village experience. The food was great and the individual cabins were really cool with downtown in the background. It was a lot of food though!

I gave the “Always On Display” feature of the iPhone 14 Pro several weeks to get used to, but have finally turned it off. When the display is on it catches my attention every time I see it. It leaves me wondering if there is something I need to check. No good.
Mason Jennings at The Dakota
I don’t remember exactly when I heard Mason Jennings first album but it wasn’t long after it was out and I played it a lot. It was a real treat that he played a number of those songs at the Dakota this evening, and I was surprised to realize that I still knew the words to nearly all of them after so many years. This show was a real treat. 🎶
Scene from Potluck MN Food Hall.
I minted Cat #2230 of the Ukraine Cats Division. This NFT project is raising funds to help Ukraine defend itself. I think I’ll mint a few more and get a Ukraine Cat Platoon going. 😸🇺🇦
The Bad Guys
We finished our “snowpocalypse” movie series tonight with The Bad Guys. We watched three movies in three nights! That is a very rare thing for the Thingelstad family. This was a fun movie with multiple callbacks to other heist movies like Oceans 11. I may have nodded off a couple of times. 🥱
Family game of Five Crowns tonight. Tyler won with just 66 points! Tammy had 86, Jamie with 108, and Mazie with 178.
From The Economist, World in Brief, February 24 2023.
Sam Bankman-Fried, a former billionaire and founder of FTX, a collapsed crypto exchange, was charged with four new criminal offenses, including conspiracy to commit bank fraud and securities fraud. Prosecutors allege that Mr Bankman-Fried developed a “series of systems and schemes” through which he could “access and steal” billions of dollars of customer deposits. Mr Bankman-Fried has pled not guilty to all of the eight original charges against him.
Bankman-Fried was a criminal mastermind more than any crypto mastermind.
Who Invited Charlie?
We continued our “snowpocalypse” movie series tonight. This evening a bit more justified with over a foot of fresh snow on the ground. We watched Who Invited Charlie?. The movie revisits the COVID-19 lockdowns following a wealthy family as they escape New York City to the Hamptons, and their visitor Charlie joins them.
MnTech Leadership Forum: Generative AI
Today I hosted the MnTech Q1 2023 Tech Leadership Forum. The organization is changing the format of this event to have technology leaders run these quarterly forums. I thought it would be fun to focus on the topic that is making so much press lately — Generative AI: Harnessing Disruption into Innovation.
I was lucky enough to get three others to join in the dialog:
- Todd Van Nurden, Principal Developer Cloud Architect and Mad Scientist, Microsoft Technology Center’s
- Sam Pierson, Chief Technology Officer, Talend
- Tammylynne Jonas, Global CIOGlobal CIO, Donaldson
Some of the topics discussed:
- Why now? AI has been in the works for a long time. Has there been a technological breakthrough recently?
- How does Generative AI affect how we build software.
- How does Generative AI benefit from these early releases.
- Opportunities technologists see to use this capability in their organizations.
- What are some of the risks to keep an eye on?
- AI as a coach or mentor?
Since it was an invite only event for members there isn’t a video to share. 😕
Of course there is a POAP for the event! And even more exciting, the POAP is also held by POAP.MnTech.eth which is the first POAP that MnTech is officially producing.
Dog Gone
With the “snowpocalypse” bearing down on us we decided to make it a movie night. We all love movies about dogs, especially Tyler. Tammy had Dog Gone on her “to watch” list for a while. Then I saw the Walker family had watched it and suggested we would like it.
Good movie about growing up and the, the relationship between parents and their kids, and of course about a great dog.
We had fun watching Amazing Race S34 E11 as they raced through Iceland and visited so many places that we were at this summer! 🇮🇸
Ukraine Stamps
One of our team members from Ukraine was able to visit us here in Minneapolis for the first time since before the pandemic. The team sent three of the Ukrainian postage stamps as a gift. I have these safely stored away until I can get them framed. 💙💛
The events from left to right in the image are: Russian Warship on Snake Island, the Crimean Bridge blast, and “Kherson is Ukraine!”. 🇺🇦
Florida Man may be the strangest board game I’ve ever played. With that said, a large group of adults having a few beverages would have a lot of fun with this somewhat silly game.
I Adopted Thinking Face Emoji
I ran across this Adopt a Character campaign from the Unicode Consortium and felt like a donation made sense. But what emoji to pick? After thinking through a few I decided Thinking Face. 🤔
This is fun, but I think it would be so much cooler if this program worked by selling NFTs. It has all the right characteristics with Gold and Silver levels being limited, and Bronze being “open editions.” It would be really fun to have this in my wallet as proof of participation.
Macaron Class
We drove an hour out to Buffalo, MN this morning to take a macaron class at Abundant Kitchen led by owner Becki Melvie.
Melvie shared that the recipe was taught to her by Nikkolette of Nikkolette’s Macarons, which we have had before and thought were amazing! The recipe had a lot of precision with all ingredients in grams. I didn’t find the macarons that complicated, but they are definitely very fussy. I tend to like things that are fussy, like fancy coffee. 😁
Our blue macaron shells came out well but had a pretty wide variety of sizes. Not bad though for our first try!
The orange shells were made by the instructor and we filled them. This was my very first macaron that I made, and it was all gone in just two bites. 🤤
To Kill a Mockingbird
We went to the Orpheum to see To Kill a Mockingbird with new screenplay by Aaron Sorkin and directed by Bartlett Sher. It was an incredible and powerful performance. Richard Thomas was so engaging as Atticus Finch. Some may remember him as “John-Boy” from The Waltons.
