I've created a simple landing page, I still have to figure out a proper name for this crypto portfolio app. Will continue working on the main dashboard, let me know if you are looking for specific information as portfolio TVL, allocations, assets list...?
Still working on a portfolio dashboard. Here is an idea of what it would be (just took another wallet address here for demo)
Will now work on transaction history. For the DeFi part, let me know which DeFi app I should display first. I am thinking of starting with lending protocol
After using so many chains, it is still a nightmare for me to easily track my assets. I have decided to tackle this by creating a platform to visualize everything in one place.
This is my new side project of the moment. Stay tuned, time to cook.

Ever entered a Twitter giveaway wondering: "Was the winner actually chosen fairly?"
Or tried running one but struggled to prove it was legit?
We wanted to tackle down this problem at @ETHGlobal Prague and create TrustGiveway. ⚖️
In our approach, we use:
- @vlayer_xyz to verify your Twitter account and ensure you have participated in the contest.
- @PythNetwork Randomness, to randomly and fairly pick the winner.
- @blockscout to verify smart contract automatically and ensure the rules are clear to all.
With TrustGiveaway, we’re building contests you can truly trust.

Is it normal that boarding passes have no digital signature?
Meaning: anyone can modify or generate one? 😳
That’s my discovery of the day. Let me explain how I got there:
This is 2025, and no cryptographic integrity on airline tickets? That blew my mind.
