Over the past six months, Morpho’s Gauntlet Prime vault on Base has grown into Sierra’s largest source of yield and recently exceeded $15M in deposits. Despite several notable incidents across DeFi platforms throughout this period, Sierra has experienced zero issues, reinforcing the unique advantages Morpho provides. Read this blog to learn about why Sierra has chosen Morpho, the unique benefits it provides and how it fits into the institutional-grade infrastructure powering SIERRA.

Why Morpho?

Morpho has grown into the second-largest decentralized lending platform in the world and is pioneering vaults as a superior lending primitive. Through fostering an extensive ecosystem of risk curators, Morpho vaults combine isolated markets into customized risk profiles that suit the goals of lenders like Sierra. This isolated approach enables the segregation of risk in lending against collateral, in contrast with pool-based protocols where lenders are exposed to all eligible collateral types. 

This resilient architecture has translated into nearly two years of consistent performance without any drawdowns, despite several periods of heightened market stress across October 10th, the subsequent crash of Stream Finance and more recently the compromise of Resolv protocol. Here is the performance of the Gauntlet Prime vault on Base since its inception in July 2024:

In addition to its resilient architecture, Morpho has implemented an extremely friendly user experience for institutional suppliers of liquidity like Sierra. As newly minted SIERRA results in idle USDC in the liquidity buffer backing SIERRA, we can immediately deploy the USDC into the OpenTrade vault representing the Gauntlet Prime vault on Base. This instant deployment minimizes cash drag, which is further improved by no fees on deposits into Morpho vaults. 

Similarly, redemption requests by Authorized Participants for SIERRA can be seamlessly met through instant, free withdrawals from the vault on Morpho. Using Morpho for yield complements the investment-grade RWAs backing SIERRA, as we can provide 24/7/365 redemptions outside of banking hours, which improves the secondary market liquidity. The Gauntlet Prime vault on Base has proven resilient through multiple periods of heightened market fear, with consistently more than $100M in available liquidity. 

Lastly, Morpho has built an impressive ecosystem of institutional users, most notably with the “DeFi Mullet” partnerships with platforms like Coinbase. Through these partnerships, Morpho has onboarded a diversified, durable user base of borrowers that provide consistent demand for capital supplied by lenders like Sierra. As Morpho continues to expand its partnerships and integrations with similar platforms, Sierra benefits from increased capacity to deploy capital, higher yields received as a lender and an increasingly diversified pool of borrowers.

“Morpho has seen tremendous growth in DeFi lending market share over the past few years through building an innovative approach with isolated lending and dedicated risk curation. Sierra’s allocation to Morpho as part of its reserve management strategy highlights the benefits to institutional allocators that Morpho is uniquely positioned to provide. We look forward to seeing Sierra continue along its growth trajectory and expand its TVL deployed into Morpho throughout 2026 and beyond”, Liam McDonald, Growth at Morpho.

Resiliency of Isolated Architecture

As mentioned, Morpho has pioneered the approach of isolated lending in DeFi. Sierra has specifically underwritten the Gauntlet Prime vault on Base, which nearly exclusively lends USDC against cbBTC at conservative risk parameters. This approach has enabled Sierra to deploy capital throughout multiple periods of heightened market stress, volatility and uncertainty around collateral quality, without experiencing any losses, gaps in liquidity or risk of undercollateralization. 

“We’re extremely proud of the demonstrated resilience of the Gauntlet Prime vault on Base throughout the past six months, as it has consistently highlighted the unique advantages of isolated lending. We look forward to working more closely with Morpho as the industry-leading platform for isolated lending, as Sierra begins to expand eligible collateral beyond cbBTC. Onchain, overcollateralized lending provides unique benefits to SIERRA’s liquidity profile, which will be essential as TVL expands and new forms of adoption are unlocked” Kevin Mills, Core Contributor at Sierra.

We view major market events as real-time stress tests, which helps improve our ongoing underwriting of Morpho as a yield source. During these events, institutional suppliers of liquidity like Sierra can observe protocol performance, the occurrence of loan liquidations and bad debt, as well as the potential gridlock of market utilization and liquidity. Throughout the market crash on October 10th, subsequent collapse of Stream Finance and Elixir, and most recently with the compromise of Resolv protocol, we have been consistently impressed with the performance of the Gauntlet Prime vault on Base. Despite some issues on Morpho with some collateral assets (i.e. xUSD, deUSD, wsUSR and RLP), Sierra has never experienced any degradation, market risk or periods of illiquidity. Given these events, we are confident that the Gauntlet Prime vault on Base will continue to be a secure allocation strategy and core component of the portfolio of reserves backing SIERRA.

Sierra’s Institutional-Grade Infrastructure

The Sierra Protocol has been developed on an end-to-end institutional-grade foundation. All custody of reserve assets backing SIERRA is managed on Fireblocks, which includes address whitelisting, transaction policy enforcement, high quorums for signing, and disaster recovery supported by Station70. Each yield source is managed as a unique vault provided by OpenTrade. All of the DeFi yield sources, including the Gauntlet Prime vault on Morpho, are monitored 24/7/365 through Hypernative.

In addition to security, Sierra aims to enable sufficient transparency for all SIERRA holders. This is achieved through a multi-step process, including:

• Real-time monitoring of onchain reserves held in Sierra’s Issuer Vault

• Real-time Transparency Dashboard hosted on Sierra’s app

• Weekly Vault reports published by Five Sigma Finance, which are published on the Transparency Dashboard

SIERRA holders can take an additional step towards transparency by examining the Gauntlet Prime vault directly on Morpho’s user interface, which provides real-time data on vault liquidity, utilization and allocation across underlying markets like cbBTC/USDC. Altogether, these sources of transparency provide SIERRA holders with assurance of the underlying reserves backing SIERRA.
