Asset and Context Transfer
1. Private Cross-chain Transfer of Assets & Logic
Xythum enables the private movement of both assets and execution logic across chains. We go beyond traditional bridges to support:
- Asset transfers (ERC-20, native tokens, NFTs)
- Smart contract contexts (state and execution logic)
- User intents (limit orders, swaps, governance votes)
2. How It Works
Instead of publicly exposing data on a source chain and replicating it on the destination, Xythum uses a darkpool gateway model:
- Source chain user submits a request to a private gateway node.
- The gateway performs secure multi-party computation (SMPC) or FROST/ZK-based validation off-chain.
- Only the final commitment is sent to the target chain.
- No sensitive data (like amounts, user addresses, or origin chain) is exposed.
This allows us to move both value and context/state across chains privately and non-interactively.
3. Supported Use Cases
- Cross-chain DeFi: Privately execute a swap from Arbitrum to Monad without revealing routes or amounts.
- NFT Migration: Move NFTs from Ethereum to Avalanche while preserving metadata and ownership under zero-knowledge.
- RWAs: Transfer real-world asset representations across chains without compliance data leakage.
- Smart Contract Context Transfer: Move governance rights or staking states privately across chains.
4. Architecture
We use a three-layer architecture:
a. Gateway Layer
- Serves as entry point for users
- Accepts intent payloads
- Runs SMPC/FROST/TEE/ZK-based validation
b. Aggregation Layer
- Bundles user intents
- Prioritizes based on gas, latency, and confidentiality
- Routes intents to destination chains
c. Settlement Layer
- Executes committed actions on the target chain
- Uses privacy-preserving primitives to hide source and route
- Issues proof receipts to the user
5. Benefits Over Bridges
| Feature | Traditional Bridges | Xythum |
|---|---|---|
| Privacy | ❌ | ✅ |
| Smart Contract Context Transfer | ❌ | ✅ |
| Non-interactive UX | ❌ | ✅ |
| Intent-based Routing | ❌ | ✅ |
| Composable Aggregation | ❌ | ✅ |
6. What is Context Transfer?
Context includes not just the data (like token balances) but also execution rights, contract states, voting power, etc.
With Xythum, you can:
- Move a partially executed DeFi contract to another chain
- Transfer staking states without reinitialization
- Migrate DAO rights with full fidelity
We achieve this via ZK-state proofs and contextual commitment schemes embedded in our aggregation layer.
7. Example Flow
Use Case: Alice wants to swap ETH (Ethereum) → USDC (Polygon) without exposing it to public mempools or bridges.
- Alice submits an intent via a gateway node.
- The gateway computes validity privately.
- Her request is bundled with others.
- Aggregation layer determines best route.
- USDC is delivered to Alice’s address on Polygon.
- ETH is debited via a ZK commitment on Ethereum.
Throughout the process:
- Her addresses are obfuscated.
- Routes are hidden.
- Final settlement proofs are auditable but private.
8. Why This Matters
Traditional bridges expose:
- Liquidity flows
- User addresses
- Arbitrage routes
- Intent front-running opportunities
Xythum eliminates all of the above, enabling private capital formation, stealth DeFi strategies, and compliance-aware cross-chain actions.
9. Technical Foundations
- Zero-Knowledge Proofs (ZK-SNARKs/STARKs)
- Secure Multi-party Computation (SMPC)
- Threshold Signatures (FROST)
- TEE-based Commit Chains
- Intent-centric Execution Graph
10. Summary
Xythum is not just a bridge — it's a darkpool aggregation layer for private, secure, and programmable cross-chain actions, unlocking next-gen DeFi, gaming, RWA, and governance flows.
