Oracles and Cross-Chain Interoperability

a. Oracles for minting/redeeming

• Arbitrum Pricefeeds: Chainlink for wstETH and rETH, contract variable for gmdETH, and LayerZero-based oracle for sfrxETH

• ETH Pricefeed: directly from native contracts

b. Cross-chain minting

Using layer zero tech, we will enable users to mint directly on Ethereum to receive gETH on Arbitrum and vice-versa

As ease of use has been one of the unique selling points of projects on GMD Ecosystem, we will strive to make gETH as accessible to commercial users as possible.

c. Built-in instant bridging

As such, ETH minting will be made easy with a contract that works on Ethereum mainnet, using Layer 0 to instantly bridge gETH to Arbitrum in your wallet. This function is also available for LSD holders on Arbitrum too.
