This project's goal is to create a new metadata protocol friendly to offline devices and implement it in the most critical tools available: Ledger and Kampela, as well as create tools to port it to other wallets and key management devices, including Polkadot Vault. This will involve changing the runtime code to support a new method of transaction signing that would include a proof of metadata used for transaction rendering to the user.
