Projects, notes, and experiments.
The project
This is Nadav's place for projects, notes, and small web apps.
The blockchain engraving tool was built by three security researchers, led by Nadav.
The blog has personal notes and comic reviews. The playground is for small apps and experiments.
Blockchain engraving
The tool writes a public message to Bitcoin, Ethereum, or Solana. You choose the chain and design, then pay with PayPal. A crypto wallet is optional.
The message is written to the selected blockchain. The site also keeps account, order, and engraving details in Neon so you can browse and share a link to the result.
