XRP Healthcare to shut down, XRPH and XRPHAI set for delisting amid flawed wallet row

XRP Healthcare has formalised a halt to operations and started delisting procedures for its XRPH and XRPHAI tokens. It cited a prolonged bear market and failed exchange listing efforts, but attention has focused on technical weaknesses in its wallet code that were raised from the project’s early stages. A July 3 attack stole funds from 4,011 wallets, and former Ripple-related developers later publicly criticised the project’s structure and management.

Bitcoin community stirred by puzzle wallet built on Satoshi\'s genesis block data

A puzzle wallet designed to help infer a private key using public data from Bitcoin’s genesis block mined by creator Satoshi Nakamoto has appeared on the Bitcoin blockchain. Galaxy Research analysts spotted related on-chain activity in block 963,629, including a 255-byte text in an OP_RETURN field and a 250-satoshi mining fee. The creator said the entropy is extremely low and also offered paid hints in return for bitcoin transfers.

Ledger CEO says crypto wallets have no total safety, design to prevent mistakes is key

Ledger CEO Pascal Gauthier said hardware wallet security cannot be solved by user vigilance alone and that “total safety” does not exist. He said makers should design systems that remain secure even when users make mistakes, citing incidents in the hardware wallet industry including CoinKite’s Coldcard and a subsequent bitcoin theft tally. He also pointed to a Trezor customer data exposure and urged continuous testing rather than accepting security claims at face value.
