Organizations Implementing Chain-Signatures for Cross-Chain Authentication, Threshold Multisignature and Interoperable Key Management
Discover organizations—projects, wallets, infrastructure providers, and research teams—that implement chain-signatures to enable secure cross-chain authentication, atomic swaps, off-chain signing flows, and interoperable key management. This curated list highlights real-world implementations, SDK integrations, on-chain verification patterns, security artifacts (audit reports and bug-bounty results), and deployment notes so you can compare cross-chain signature schemes, threshold and multisignature protocols, cryptographic primitives, threat models, and maturity levels across teams. Use the filtering UI to narrow results by protocol, programming language, security audit status, deployment environment, or integration type; then review technical docs, SDKs, and audits and contact maintainers to accelerate evaluation, integration, or collaboration.
