RiskRelay is an omnichain decentralized hedge and risk management protocol built on ERC-4626 standard vaults across EVM-compatible chains. This initiative aims to assess the feasibility of a cross-chain protocol that uses generalized message passing bridges like LayerZero, Hyperlane, and Chainlink's CCIP for message passing. The protocol taps into each chain's unique strengths: for example, Flare offers inbuilt Oracle solutions, Base provides liquidity, and Fhenix, Oasis and Inco has shielding capabilities - good for hiding bet amounts in prediction markets.

Decentralized Risk Hedge Protocol

This project is a Solidity-based decentralized risk hedge protocol designed to combine the best features of multiple blockchain ecosystems. It leverages Chronicle, Flare's FTSO Contracts, and PYTH for oracle data and uses Hyperlane and LayerZero to enable seamless message passing across chains. Vaults holding hedge and risk assets are deployed on chains like Morpho, Mantle, Linea, and Base, each selected for its unique strengths.

Core Components

1. MarketCreator
   The MarketCreator contract creates and manages risk and hedge vaults for each market.

   • Market Creation: The createMarketVaults() function allows creating a pair of risk and hedge vaults for a market.
   • Market Lookup: The getVaults() function retrieves the addresses of the vaults for a specific market.

   It maintains a mapping of market IDs to their corresponding vault addresses.

2. RiskVault & HedgeVault
   These contracts represent the "risk" and "hedge" sides of a market, respectively.

   • Deposit and Withdrawal: Users can deposit funds into the vaults and withdraw their shares later.
   • Asset Transfer: Assets can only be transferred to the "sister" vault as controlled by the MarketCreator.
   • Standardization: Both vaults are built on the ERC4626 standard for tokenized vaults.

3. Controller
   The Controller retrieves data from oracles and determines whether to mature or liquidate the vaults based on market conditions.

Experimentation with Configurations

We explored various configurations to combine the best features of multiple chains:

• Single-Chain Deployment: In one setup, all contracts were deployed on a single chain, showcasing simplicity and direct oracle integration.
• Oracle Flexibility: Different oracles, such as Flare’s FTSO and PYTH, were used to assess compatibility and data quality.
• Cross-Chain Setup: The controller was deployed on one chain, such as Base, to access premium oracles like Chronicle. Vaults were placed on other chains like Mantle or Morph to leverage liquidity or privacy features.

Leveraging the Best of Different Worlds

By experimenting with deployments across various chains, we aimed to create a system that combines:

• Robust Oracle Data: Accurate and reliable price feeds from Chronicle, PYTH, and Flare's FTSO.
• Liquidity Access: Deploying vaults on chains like Base ensures access to high liquidity.
• Privacy Features: Chains like Oasis offer confidentiality for sensitive data.

This modular and flexible design demonstrates the potential of a decentralized risk management system capable of adapting to the strengths of different blockchain ecosystems. While there’s room for deeper analysis, the groundwork is set for a powerful, cross-chain solution.
