Keyring implementation for arbitrary JSON data designed to be used by MetaMask for managing accounts isolated by snap origin.
Accounts for each snap are isolated by identifier so callers should ensure that the identifiers are stable and safe to use for isolation purposes.
yarn setup
yarn test
The dist build is not the same as the build used for testing as the requirements differ; the distribution build requires an ES2016 target so that class member variables are stripped as they are not supported by the MetaMask build system:
yarn dist
This script is always run in prepare so that publishing includes the latest dist and not any test artifacts.
