Staking Options on Metis with DIA Price Oracles

Introduction

Dopex is a decentralized options protocol which aims to maximize liquidity, minimize losses for option writers and maximize gains for option buyers. Dopex’s Single Staking Option Vaults allow users to lock up tokens for a specified period of time and earn a yield on their staked assets. Users will be able to deposit assets into a contract which then sells your deposits as call options.

Challenge

The Dopex team was looking to go multi-chain and launch a new Single Staking Option Vault on the Metis Andromeda network and list the network’s native token METIS in the vault. To do so, Dopex required a reliable price feed for Metis/USD, supplied as an oracle on the Metis network. The price oracle was required to be resilient to price manipulations and middleman attacks, avoiding putting users’ funds at risk.

Solution

DIA deployed a dedicated METIS/USD price oracle for Dopex. In order to ensure the feed’s resilience to bad actors, its value is determined by leveraging trade data from 10+ markets and applying a MAIR methodology. As a result, the feed is not reliant on a single market, avoiding a single point of failure. The oracle is set to push updates on-chain when a price deviation of 5% from the last reported value happens, following the specifications that Dopex provided via a DIA CDR.
