Overview

This episode of 0xResearch features Sam MacPherson, co-founder and CEO of Phoenix Labs, the main contributor to Spark, alongside Luke from Blockworks Research and host Pocachio. Sam delves into the recent rebranding of MakerDAO to Sky and the subsequent restructuring of its governance, explaining the shift from a monolithic DAO to a system of prime agent subdows like Spark. He highlights the challenges of previous DAO structures, emphasizing their lack of scalability and strategic direction, and how the new Sky framework aims to foster decentralized, competitive growth while maintaining robust risk management.

The conversation also explores Spark's conservative approach to DeFi lending, particularly its liquidity layer and how it navigated recent market incidents like the Kelp exploit. Sam details Spark's focus on blue-chip collateral, its preference for isolated markets for higher-risk products, and its commitment to providing the safest possible ETH yield. He also touches on the decision-making behind offboarding certain assets and winding down exposure to platforms like Ethena, always prioritizing risk-adjusted returns.

Furthermore, the episode unpacks Spark's risk framework, which evaluates collateral, custodians, facilitating entities, and borrowers, contrasting DeFi's anonymous nature with TradFi's legal obligations. Sam introduces Credora's independent risk ratings for Spark's savings vaults, emphasizing the importance of external validation for industry maturity. He also discusses Spark's liquidity intents for institutional depositors, the rationale behind SPK token buybacks, and Spark's competitive landscape, positioning itself against fintechs and eventually traditional banks. The discussion concludes with insights into Spark's future focus on growing its USDT balance sheet and developing prime brokerage solutions for crypto hedge funds.

Key Concepts

01

Sky Ecosystem & Subdows

Sky is the rebranded MakerDAO, acting as a wholesale credit and stablecoin issuer (USDS). Spark is one of its 'prime agent subdows,' operating as a commercial lending arm. Sky defines the overarching risk framework, while subdows pursue growth opportunities within those guidelines, with junior capital requirements ensuring 'skin in the game.'

Why careThis new structure aims to address the scalability and efficiency issues of previous DAO governance models, fostering decentralized competition and innovation.

02

Spark Liquidity Layer & Sparkland

Spark's internal lending market, Sparkland, is designed for conservative, blue-chip collateral like ETH and LSTs (Lido, Etherfy ETH). The Spark liquidity layer primarily allocates to Sparkland, but also to Morpho, ensuring full control over risk management.

Why careThis layer provides a robust and secure foundation for ETH yield generation, attracting users seeking low-risk, liquid staking derivatives.

03

E-mode (Efficiency Mode)

A high-leverage mode (92-93% LTV) in lending protocols like Aave, allowing for 10-15x leverage. Sparkland restricts E-mode to Lido staked ETH only, aiming to provide the safest possible construction for ETH yield.

Why careCareful management of E-mode is crucial for mitigating risk, as high leverage can amplify losses during market volatility.

04

Isolated Markets (e.g., Morpho Blue)

Lending markets where risk is contained to specific collateral types, allowing for better pricing controls and easier unwinding of positions compared to pooled lending markets.

Why careThese markets are preferred by Spark for higher-yield, higher-risk products, as they offer greater flexibility and risk isolation, crucial for institutional-grade operations.

05

Four Pillars of Risk Framework

Spark's credit underwriting framework evaluates four key areas: the collateral asset, the custodian (governance in smart contracts, or qualified custody off-chain), the entity facilitating the lending, and the borrower.

Why careThis comprehensive approach helps assess and manage the unique risks associated with both DeFi and traditional finance credit instruments.

06

Liquidity Intents

An asynchronous request mechanism for large depositors in Spark Savings to signal their intent to withdraw significant amounts. The automated allocation system then fulfills the request, often in the next block, improving user experience for institutional clients.

Why careThis feature addresses the limitations of synchronous withdrawals for large sums, ensuring high liquidity for institutional depositors without dragging down overall yield.

07

Prime Brokerage (Spark Prime)

A future initiative by Spark to enable crypto hedge funds to collateralize and margin across exchanges, qualified custodians, and DeFi protocols. This aims to drastically improve capital efficiency for various trading strategies.

Why careThis will unlock significant market opportunities by providing a robust, overcollateralized lending venue for hedge funds, scaling to billions in volume during bull markets.

Quotes

"The goal is actually to make this the safest possible construction for ETH yield because I think this is actually what most people want. They have their ETH and they want to get a yield on it. They want to remain liquid and so they just want to toss it into the lowest risk yield generation."
Sam MacPherson Explaining Sparkland's strategy for ETH yield and E-mode restrictions.
"It's not like is it good, is it bad, is it too risky. It's like what is the risk adjusted yield? This is always the calculus that you're going for. And so this will be taking the absolute yield and then discounting it based on the perceived risk."
Sam MacPherson Describing Spark's philosophy for evaluating and allocating capital to various opportunities.
"We increasingly feel is necessary, we see the way the market has been evolving over the years and I think without this sort of like independent check on who is doing the risk curation, you kind of have this tendency due to competition for people to just keep risking on."
Sam MacPherson Highlighting the importance of independent risk ratings like Credora's to prevent a 'race to the bottom' in DeFi.
"We just want to focus at what we're good at and we do not do consumer at all. And I think it's, you know, we want to break our team is not particularly big."
Sam MacPherson Explaining Spark's strategic decision to focus on backend collateral and institutional clients rather than direct consumer fintech.
"The D5 mullet thesis, we're big believers in that. So these consumer apps are going to hook into the blockchains through these lending markets or yield products. And so we don't necessarily have to be directly attached to the users there."
Sam MacPherson Discussing how Spark will integrate with consumer-facing platforms without directly building them.
"Unlike a corporate structure where there's kind of like a leader, there's a hierarchy and leadership, the structure of the workforce within MakerDAO was segmented by function... there's no leadership on top. So every it's like choose your own adventure."
Sam MacPherson Illustrating the inefficiencies and paralysis of the previous MakerDAO governance model.
