Required Methods§

Source

fn sign_frost( &self, signing_jobs: Vec<FrostSigningJob>, ) -> Result<SignFrostResponse, SparkSdkError>

Signs a message using FROST threshold signature scheme

§Arguments
  • request - The request to sign the message
§Returns

The FROST signature

Source

fn aggregate_frost( &self, request: AggregateFrostRequest, ) -> Result<AggregateFrostResponse, SparkSdkError>

Aggregates multiple FROST signature shares into a complete signature

§Arguments
  • request - The request to aggregate the FROST signatures
§Returns

The aggregated FROST signature

Source
