Hyperbridge Protocol
Hyperbridge is a secure system that allows different blockchains to communicate with each other. This communication facilitates the transfer of assets on the blockchain. Unlike older methods that relied on groups of people (multisig committees) to approve transactions, Hyperbridge uses a more robust approach. It leverages the collective agreement of the entire network (consensus) and verifiable proofs (state proofs) to ensure that all communication is fully secure, just as if it were happening on a single blockchain. This decentralized method removes the main point of weakness that has led to billions of dollars in losses in the past. Hyperbridge is the first of its kind in the world.

Multipli Smart Contracts
Multipli is a ZK-based yield protocol that enables yield generation on traditionally non-yield-bearing assets (XAUT, BTC, etc.) and boosts the yield efficiency of any asset by 4–12%. This bug bounty program focuses exclusively on on-chain smart contract code, including vault logic, financial computations, token accounting, upgrade paths, ZK-integrated contract logic, and overall protocol integrity. Researchers are invited to uncover vulnerabilities that may compromise fund safety, protocol correctness, or economic soundness.
