Ledger

Ledger builds hardware wallets and companion software for people who want to keep private keys under their own control instead of leaving assets on custodial platforms.

Its official materials center on secure signing devices, the Ledger Wallet and Ledger Live experience, and support for buying, swapping, staking, and managing a wide range of assets.

Within the TON ecosystem, Ledger is most relevant as a security layer for holding Toncoin and approving transactions through self custody hardware rather than a wallet that is built only for TON users.
