pub struct Signer<T: SigningTypes, C: AppCrypto<T::Public, T::Signature>, X = ForAny> { /* private fields */ }
Expand description

Provides an implementation for signing transaction payloads.

Keys used for signing are defined when instantiating the signer object. Signing can be done using:

  • All supported keys in the keystore
  • Any of the supported keys in the keystore
  • An intersection of in-keystore keys and the list of provided keys

The signer is then able to:

  • Submit a unsigned transaction with a signed payload
  • Submit a signed transaction

Implementations

Use all available keys for signing.

Use any of the available keys for signing.

Use provided accounts for signing.

Note that not all keys will be necessarily used. The provided vector of accounts will be intersected with the supported keys in the keystore and the resulting list will be used for signing.

Check if there are any keys that could be used for signing.
