 Overview Contract catalog Choose by use case Permissions & operations Agreements, credentials & debt MultiTrustCredential .sol @hazbase/kit @ 0.9.0 
 Role and use
 Use for metrics such as operational assessments or eligibility, separating metric updates from proofs about those metrics.
 Integration considerations Define authorized metric issuers and proof types. Match proof-generation circuits and public inputs to the verifier.

 Key SDK operations
 These operations are exposed by MultiTrustCredentialHelper in @hazbase/kit@0.9.0. The signatures below are type definitions; see the SDK reference for parameter structures and the complete interface.
