The core idea: connecting your addresses Every bitcoin transaction is written into a public ledger that anyone can read, forever.

How to Store a Seed Phrase for Inheritance Planning To store a seed phrase for inheritance planning, you need a setup where your heirs can recover your bitcoin after you die, but nobody can touch it while you are alive.

The $200,000 Morse Code Heist In May 2026, an AI agent gave away roughly $200,000 because someone talked to it in Morse code. The target was Bankrbot, a crypto trading agent operating on X.

Wallets in safes and safety deposit boxes were drained while their owners slept. The story did not end there. September brought three real developments: hardened firmware releases, a white-hat recovery…
A few days after its much-discussed “can’t see vs won’t look” post, XYZVault announced its launch on Stacker News in June 2026: a privacy-focused multisig vault platform with a 30-day free trial. The announcement repeats the architecture from the discussion post and adds one useful conceptual frame: wallet-metadata privacy is a separate problem from private-key…
