# zkBridge Expansion (Cross-Chain Integration)

### **zkBridge Expansion (Cross-Chain Integration)**

While zkShine is native to Solana, it is **architecturally designed for cross-chain interoperability**.\
Through the upcoming **zkBridge** system, zkShine will extend its privacy proofs and relay capabilities across other major ecosystems.

#### **Phase 1 — Ethereum & Arbitrum**

* zkProof relaying for Ethereum-based dApps
* Anonymous transaction bridges
* zkVault mirroring for private data portability

#### **Phase 2 — Sei & Sui**

* Integration with high-performance chains for AI and trading privacy
* zkML interoperability for cross-chain compute validation

#### **Phase 3 — Cosmos / IBC**

* zkProof messaging layer compatible with IBC networks
* zkReputation portability across multiple DePINs
