hopper-multisig

M-of-N signer threshold checks for Hopper programs. Duplicate-signer prevention, zero heap allocation, and a fixed stack footprint.

Part of the Hopper framework.

Pass the account views that are allowed to satisfy the threshold. Hopper checks that each address is unique, counts real transaction signers, and returns MissingRequiredSignature or InvalidArgument when the set is not valid.

use hopper_multisig::check_threshold;

check_threshold(&[admin_a, admin_b, admin_c], 2)?;
