COZ has updated the Neon Wallet with support for Ledger Nano S/X devices on N3, enabled by the recent addition of the Neo N3 app to Ledger Live’s app store. Currently only available in “developer mode,” users will be able to install the new N3 Ledger app alongside the Legacy app on their devices in order to migrate assets.

Update September 15th: The Neo N3 App is now fully approved by Ledger and available on the Ledger Live store without switching to developer mode.

Step-by-step instructions on completing the process of moving NEO and GAS tokens to the new network have been provided by the team. Users will need to download the latest version of the Ledger Live software for their operating system and toggle on developer mode from within the experimental features settings tab.

Nano X and S devices will require at least firmware version 1.3 and 2.0.0 respectively. Once both the Neo Legacy and N3 apps are installed, users can visit the Neo Legacy Ledger login page to begin the migration process. After following the steps and waiting for the migration process to complete, which can take from as little as 5 minutes to potentially as long as 24 hours, migrated assets can be accessed by logging in with the Ledger N3 app.

Some Ledger users may encounter issues signing transactions. These issues originate from the Neo Legacy UTXO model, where each transaction of NEO or GAS is made up of multiple unspent outputs (UTXOs), like in Bitcoin. Ledger devices, with their limited memory capacity, can only process a limited number at a time.

This can affect users that perform large numbers of small transactions, such as frequent GAS claims. COZ published information on how to rectify the issue by consolidating UTXOs on its Medium. In short, users are recommended to send small amounts of the token to their own receiving address, or use one of the provided tools available from O3 or Splyse.
