Ledger SDK queries transaction information from the server when signing... states it does not store it

Not investment advice. Muhabbit scores how much a story may matter, not which way to trade.
Ledger’s hardware-wallet SDK queries a Ledger server during transaction signing, a practice the company says is required for clear signing and involves no data storage. The issue was raised on X by Ambire developer Kaloyan Kosev, who argued privacy should be the default and that wallet developers must change settings to stop each signature from sending data to Ledger’s servers. Kosev listed the transmitted items as the transaction network, contract or recipient address, device model and firmware version, app version, and whether blind signing was used. The disclosure matters because Ledger devices are widely used to secure crypto holdings, so any per-signature server call touches a large share of self-custody users. Watch whether Ledger changes SDK defaults or adds opt-outs, and whether other wallet integrations follow suit.
