Zynk Protocol
Zynk is a just-in-time liquidity and settlement infrastructure layer for cross-border payment companies. Payment companies often need to pre-fund transactions to provide fast settlements — this ties up capital, slows growth, and makes treasury operations unnecessarily complex. Zynk removes that bottleneck by providing liquidity on a transaction-by-transaction basis, allowing companies to settle faster without locking up idle capital.

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.
