cacti

Hyperledger Cacti is an open-source framework designed to enable secure, scalable interoperability between different blockchain networks. It targets developers and enterprises needing to connect disparate ledgers (e.g., Hyperledger, Ethereum, Corda) for asset transfers, data sharing, or atomic swaps. Its pluggable architecture and focus on both legacy and modern systems make it uniquely interesting for solving real-world, multi-blockchain integration challenges.
