Ledger Nano App for Kusama CC2
Now that Kusama CC2 version 1007 is out.. we have updated the Ledger Nano app and are ready for the community to start playing with it! Please test and send any feedback! This is the first step towards supporting a wide range of Substrate based chains! We have released an npm library to simplify integration into existing wallets. A compatible rust crate is coming very soon… (subkey integration anyone?) Using the npm package, amazing Jaco Greeff did already integrate things into Polkadot-U
Now that Kusama CC2 version 1007 is out.. we have updated the Ledger Nano app and are ready for the community to start playing with it! Please test and send any feedback! This is the first step towards supporting a wide range of Substrate based chains!
We have released an npm library to simplify integration into existing wallets. A compatible rust crate is coming very soon… (subkey integration anyone?)
Using the npm package, amazing Jaco Greeff did already integrate things into Polkadot-UI! In order to enable, you need to go to Settings and set manage hardware connections to Attach Ledger via WebUSB.
Then you can use a Ledger Nano S in most places :)
Installing the app
We are finalizing some details and we will soon send the app to Ledger for review.
If you have time, In the meantime, you will need to compile and install the app yourself. Please follow the instructions here and skip setting the test mnemonic. Use your own mnemonic!
Some Notes
- Subkey and Ledger Nano mnemonics are not compatible. Ledger derives using BIP44 path 44'/434'/x’/x’/x’ ( Thanks Afri Lastname for the registration!)
- The app supports Spec 1007
- Apache 2.0 — USE AT YOUR OWN RISK! This is Kusama = Chaos!
- Only Ed25519 is supported for now.. but Kusama not allows Ed25519 everywhere!
What’s next for Kusama / Polkadot?
- Remote signer support in substrate + a great TEE-based validator software+hardware stack.
- Automatic code generation for Substrate-based Ledger apps
- Sr25519 support in Ledger devices
