Hello everyone 👋

I’m excited to introduce Paperweight, a local-first open-source desktop app I’ve been building to help people understand and reduce their digital footprint.

The core idea: your inbox is a paper trail of every company that has ever had your data. Every account you created, every service you tried, every online purchase. It’s all connected to your email. Most people have 100+ accounts they’ve forgotten about, each a potential security, or privacy risk. For me the final push was the Odido data breach in the Netherlands. I hadn’t been a customer for more than 8 years, but all my data was still in their systems.

What it does:

• Account inventory — Maps every company that has ever emailed you, with risks classifications and recommendations for action.

• Bulk unsubscribe — Find and unsubscribe from any marketing and mailing lists (auto RFC 8058 where supported).

• Breach alerts — Alerts when any company you’ve been in contact with has been breached (via HaveIBeenPwned).

• GDPR requests — Generates pre-filled GDPR requests in multiple languages.

Privacy approach:

Everything runs on your machine. Email content, credentials, and connection details never leave your device. No telemetry, no cloud sync, no analytics. The code is fully open source and auditable on GitHub.

• Website https://www.paperweight.email/

• Github https://github.com/wslyvh/paperweight

Would love to hear any feedback. Thanks!

Wesley

I haven't posted here in a long time but, as I'm transitioning into a new role, it seems like a good time to start writing again. Moving forward, this newsletter will be migrated to Paragraph, with a focus on keeping track and exploring privacy on Ethereum. I hope you will continue to follow me over there!

🗞️ News

There’s been a lot of debate lately about people paying for Goerli testnet Ether. While I don’t think there’s anything wrong with an incentivized testnet, this has not been the best way to go. Please be aware that you should NOT have to pay for using a testnet. Goerli is often used for stakers running their test validators. For everything else, use Sepolia. Sepolia is the recommended network to test smart contracts and application application development.

useful-solidity-patterns - This repo is an ongoing collection of useful, and occasionally clever, solidity/EVM patterns that actually get used in the wild. These bite-sized guides are written in approachable terms so engineers of all skill levels can understand them. Every guide comes with a concise, self-contained, working code example and tests to demonstrate the pattern. New patterns are added regularly.
