  2. imKey-core is a cross-platform SDK developed based on the rust language. It supports integration with mobile applications, PC applications, and web pages, and can be well integrated with the imKey hardware.

  3. imKey cos provides algorithm support of Keccak256, ecdsa (secp256k1), and ed25519, and has launched a firmware upgrade function to better support new algorithms and new services.

  4. imKey applet, used to parse the incoming data of SDK, verify the validity of the data, assemble the signature serialized data and execute the signature, can be updated in a dynamic way to facilitate new features and fix bugs.

  5. imKey-core is for open source. According to the plan, imKey will open source its imKey-core and applet in the near future, leveraging on the power of community to continuously improve the product to better serve the entire ecosystem.

Additional information:

  1. SDK: add CKB signature, address and other functions. Involves data verification, serialization of signature data, etc.
  2. Applet: add support for CKB.

Timeline

  1. At present, imKey hardware already supports the algorithms of Keccak256, ecdsa (secp256k1), and ed25519. New algorithms can be added through cos upgrade.
  2. imkey-core sdk that we have begun research and development is expected to be completed by the end of March.
  3. SDK and applet can support CKB, which will take about 2 months to complete.
