What is Meridian?

Meridian is an onchain trading venue on Robinhood Chain. It has two main products:

Perpetual futures

The perpetual futures exchange uses a central limit order book. Traders submit signed orders to an offchain matching system. The system matches orders and sends the resulting state changes to the exchange contracts. An external, verifiable price oracle supports margin checks, funding, and liquidations.

mPerps can remain available when the reference market is closed. During these periods, Meridian freezes the mark at the last accepted oracle price and can charge a position fee. mPerps use isolated margin pools. See Mutualized Perps and Position Fees.

Prediction markets

Meridian Predict is a prediction markets venue built on Robinhood Chain and settled in USDe.

Product Overview

  • Prediction markets - build and trade prediction singles, combos, and much more across a deep and expanding set of markets.
  • RFQ auctions - market makers compete to take the other side of each prediction at the best available odds.
  • Onchain settlement - collateral, settlement, and payouts are handled by smart contracts.

Meridian Predict's purpose-built architecture enables deep liquidity and fair price execution through its unique RFQ-based auction system. This design dramatically streamlines event pricing and risk modeling for market makers compared to traditional CLOB-based systems.

With Meridian Predict, users can make generalized single and combinatoric predictions or provide RFQ liquidity across a wide range of markets. Alongside Predict, Meridian also supports mPerps & other perpetual instruments and other core DeFi primitives.
