Morpho Midnight launches $400,000 audit competition for fixed‑rate

Morpho, the second‑largest DeFi lending platform by total value locked, has opened a public audit competition with a prize pool of up to $400,000 for its upcoming fixed‑rate protocol, Morpho Midnight [1]. The contest, hosted on Cantina, is intended to serve as the final security test before the protocol is deployed to users.

Key takeaways

• Morpho Midnight introduces intent‑based fixed‑rate and fixed‑term markets, a departure from the variable‑rate model of Morpho Blue [1].
• The bug‑bounty prize pool is $400,000, double the $200,000 offered in Morpho’s previous Cantina contest [1].
• The codebase and whitepaper were released simultaneously on GitHub around May 28 after two years of development [1][4].
• Institutional partners include Apollo Global Management, which plans to acquire up to 9% of the MORPHO token supply, and the Ethereum Foundation [1].
• Morpho Midnight’s architecture is non‑custodial, requiring airtight smart‑contract logic [1].

Fixed‑rate innovation and public testing

Morpho Midnight is designed to address the limitations of variable‑rate lending by creating isolated, immutable markets with fixed maturities. Participants trade credit and debt units that settle like zero‑coupon obligations at market maturity, and offers do not lock capital until settlement [4]. This “intent‑based” approach contrasts with Morpho Blue’s pool‑based, open‑term variable‑rate markets, which externalize risk management differently [2]. Co‑founder and CEO Paul Frambot described Midnight as “the hardest and most ambitious thing” the team has built, noting that the protocol manages roughly $7.7 billion in TVL across its existing products [1].

The audit competition, now accepting submissions on Cantina, offers up to $400,000 for anyone who discovers vulnerabilities in the Midnight codebase [1]. This bounty is twice the amount of Morpho’s prior contest, underscoring the platform’s commitment to security as it prepares for public deployment. The competition follows the open‑source release of the code on GitHub, which includes formal verification using CVL and testing frameworks such as Forge [4].

Institutional backing and market context

Beyond the bug bounty, Morpho Midnight benefits from notable institutional interest. Apollo Global Management intends to acquire up to 9% of the MORPHO token supply over a four‑year period, while the Ethereum Foundation remains a partner in the protocol’s development [1]. These relationships signal confidence in Morpho’s long‑term strategy and its non‑custodial design, which requires rigorous smart‑contract security [1].

The launch of Midnight and its audit competition coincided with other positive developments for Morpho, including a Trezor integration that allows users to earn yield on USDC and USDT through Morpho vaults [3]. Together, these announcements contributed to a modest price uptick for the MORPHO token, reflecting market around the new product and its security focus.
