D'CENT's biometric wallet uses a fingerprint sensor for signing, which is unique among hardware wallets. Ledger relies on a PIN and physical buttons.
D'CENT's biometric approach is convenient but adds a different trust surface. Ledger's PIN plus secure element model is well understood and battle-tested.
Ledger Live supports more assets and integrations than D'CENT's app, though D'CENT covers the majors well.
Fingerprint signing is genuinely quick. If convenience is your top priority, D'CENT is worth a look. If you want the most complete ecosystem, Ledger wins.
D'CENT is a solid niche pick. Ledger is the safer default for most crypto holders.
