This allows you to recover the private key that is normally locked in the Ledger hardware.\n\n\n## Installation\n\n- Clone the repo via `git clone https://github.com/jacogr/substrate-ledger-ed25519.git`\n- Change into the folder `cd substrate-ledger-ed25519`\n- Install the dependencies via `npm install` (or `yarn`)\n\n\n## Usage\n\n`npm start \u003cpolkadot|kusma\u003e \u003cmnemonic\u003e \u003caccount\u003e \u003caddress\u003e`\n\nWhere the 4 arguments are:\n\n- app type - Either `polkadot` or `kusama`, e.g. `kusama`\n- mnemonic - The full quoted 24-word/25-word mnemonic (enclose it with \" at the start and end), e.g. `\"abandon ... about\"`\n- account - The index of the account you are using, e.g `0`\n- address - The index of the address you are using, e.g. `0`\n\nMac OS / Linux:\n\n- `history -c` once completed to delete terminal history\n\nExample:\n\n  `npm start kusama \"abandon ... about\" 0 0`\n\nFull example (known seed):\n\n```\nnpm start \"kusama\" \"abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about\" 0 0\n\n\t ed25519 seed\t 0x98cb4e14e0e08ea876f88d728545ea7572dc07dbbe69f1731c418fb827e69d41\n\n\taddress (DOT)\t 15F8gp3or2mLW8yiJAZ9C3ZFpvEA8SPJDq4RXVpVjcXtdxJq\n\taddress (KSM)\t GpTCo8cccWnpFne7EKBwr677tWkEoeLbiAgks76fKisCUWP\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjacogr%2Fsubstrate-ledger-ed25519","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjacogr%2Fsubstrate-ledger-ed25519","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjacogr%2Fsubstrate-ledger-ed25519/lists"}
