Account Store

Class Name	AccountStore
Implements	KeyStoreInterface
Extends	Logger
Source	account-store.ts

The AccountStore implements the KeyStoreInterface and is a wrapper for a storage, where evan.network account ids are stored. The default AccountStore takes an account –> private key mapping as a pojo as its arguments and uses this to perform lookups, when the getPrivateKey function is called. This lookup needs to be done, when transactions are signed by the InternalSigner (see Signer).

Note that the return value of the getPrivateKey function is a promise. This may not be required in the default AccountStore, but this allows you to implement own implementations of the KeyStoreInterface, which may enforce a more strict security behavior or are able to access other sources for private keys.
