The 683M ZIL figure gets the headline, but the seven-year survival of the bug inside a Ledger-signed application is the real read for any token still relying on native hardware-wallet signing.
A seven-year-old flaw in XRP Ledger's signature library would have let an attacker derive a private key from as few as five signed transactions, putting wallets at risk before maintainers patched it.
The flaw lets private keys be recovered from any affected onchain signature; EVM transactions and SDKs are unaffected, narrowing the blast radius.
A nonce-reuse bug in the Zilliqa Ledger app let attackers reconstruct private keys from roughly five native signatures, and Upbit's cautionary-asset designation now puts ZIL trading support itself in…
Transaction sign-off stays on a physical device, so an autonomous agent can read balances and draft swaps but can never broadcast one without a human tap.
The open-source toolkit lets AI agents read balances and prepare transactions, but every sensitive action still needs physical approval on a Ledger device.
The on-chain investigator singled out Ledger and pitched an iPhone-as-signer workaround, reigniting a long-running debate over whether hardware wallets actually keep self-custody safe.
The onchain investigator argues current hardware wallets aren't fit for signing critical transactions or storing large balances, and floated a dedicated iPhone as a stronger alternative.
Both vendors agree the bug is real on a lab bench; Tangem argues it stays academic because resetting the PIN needs a laser, the card in hand, and rare know-how.
Eric Larchevêque frames a seven-figure BTC not as a victory lap for the asset, but as a tell that the world around it has broken.
Ledger's security research team has disclosed a vulnerability in the chip used by Trezor's Safe 7 hardware wallet…
The vulnerability lives on a single chip inside Trezor's new Safe 7, but the device's multi-layer architecture means attackers would still need physical access, lab equipment and deep expertise —…
The $4B-valuation deal the company lined up with Goldman, Jefferies, and Barclays in January is now on ice, with insiders flagging private fundraising as the alternative path.
No S-1 was ever filed, the banks were never paid to push through, and the $4B valuation Ledger explored in January is now sitting on the shelf alongside Kraken's shelved listing — the IPO market for…
