Do Ledger hardware wallets support IOTA?
The IOTA Foundation announced on November 2, 2018 that Ledger hardware wallets now support the storage of IOTA tokens.
To do this, the IOTA app must be installed on the Ledger hardware wallet to manage MIOTA with the official Trinity wallet. The IOTA app is developed and supported by the IOTA community. How to use your ledger with the Trinity Wallet is described on their website: https://trinity.iota.org/hardware.
