Invitation to Tender: Oracle for MCDEX DAO Pool

We are about to launch MCDEX V3 on Arbitrum rollup. The permissionless nature of our protocol shifts the power of flourishing the ecosystem to our dear community. The liquidity pools and perpetual markets are run by `operators’, who are the creators and managers of perpetual markets, and the market could be anything with an index. Therefore, a price feed is required. Operators are in charge of finding and choosing an appropriate oracle for their market.

Approved by the community in proposal 21, The MCDEX foundation will lead the process of searching for and integrating an oracle for the pool operated by MCDEX DAO.

The MCDEX DAO will create and operate a USDC pool. Initially, we will have mainstream markets like ETH and BTC and gradually expand to other assets through the governance of the DAO. Thus, we are initiating the first round of tender. The subsequent tender will come up when we plan to add new markets to the DAO pool.

  1. As an exchange for perpetual trading, a precise index price helps decrease the spread, which is essential to optimizing the trading experience
  2. To protect our markets from price manipulation, we seek an oracle solution that is as decentralized as possible
  3. To ensure the quality and stability of our platform, the oracle service has to be stable and strong

1st round Oracle tender: ETH and BTC price
