DeFi Protocols in 2026: A Founder's Perspective

Federico Sendra, the CEO and co-founder of SpaceDev, a consultancy that specializes in blockchain and Web3 technologies, shares insights on the advancements in decentralized finance (DeFi) as we look towards 2026.

Redefining DeFi Beyond Ideology

For a significant duration of the last cryptocurrency cycle, decentralized finance grappled with an unusual challenge: its technological benefits were often expressed through ideological perspectives rather than practical business rationale. While the phrase “remove the middleman” sounded revolutionary, entrepreneurs still faced the realities of acquiring customers, adhering to regulations, and maintaining profit margins.

Over my experience with various blockchain and Web3 initiatives, my focus has shifted from the mere idealism of decentralization to an understanding of how it transforms business economics. One of the most significant shifts in the DeFi landscape has been the transition of protocols from mere destinations to comprehensive financial infrastructure.

The Unbundling of Financial Services

Traditionally, banks and financial institutions have bundled services such as accounting, liquidity management, and risk assessment under one umbrella. However, smart contracts now allow these functions to be disaggregated, enabling them to be offered as reusable services. This evolution permits founders and developers to concentrate on specialized areas where they possess expertise, compliance knowledge, or robust distribution channels.

Take lending protocols, for example. Early versions often centralized liquidity, risk management, and user interactions within isolated markets. The latest designs, however, increasingly fragment these functionalities. For instance, Aave’s V4 architecture distinguishes between shared liquidity managed through Liquidity Hubs and specific market logic via Spokes, enabling multiple lending environments to utilize a common liquidity pool. Conversely, Morpho isolates its primary lending markets while using vaults that empower curators to allocate capital across these markets and set tailored risk parameters.

This transition signifies that startups no longer need to create every financial component—capital formation, settlement systems, and customer-facing products—simultaneously. Elements can now be integrated from existing infrastructures.

Focus on Competitive Edge

In the realm of software, the emphasis is primarily on code, but the same cannot be said for financial services. An exchange devoid of buyers and sellers is ultimately ineffective. Financial marketplaces face a recurring dilemma: users seek liquidity before they engage, yet liquidity providers want users onboard before investing their capital.

Open DeFi protocols provide a refreshing alternative. Entrepreneurs can construct products around pre-existing liquidity and financial activity on-chain instead of starting from scratch. As a result, the pivotal question shifts from “How do we build every aspect of this financial solution?” to “Which aspects truly give us our competitive advantage?”

Often, this advantage could be in areas like distribution, compliance, risk assessments, customer experience, or specific market access. The necessity to own every layer of the underlying infrastructure can become an unnecessary burden.

The Growing Role of Stablecoins

The rise of stablecoins is enhancing this infrastructure’s effectiveness. As of early September 2026, stablecoins have an astounding circulating value around $304 billion, while the total locked value across DeFi platforms is approximately $85 billion, according to DefiLlama. Though these figures illustrate different aspects of the market, they collectively point to the movement of blockchain activity beyond mere speculative assets towards assets designed to function as currency.

With programmable money, the array of products that can engage with DeFi expands significantly. Innovations in payments, lending, treasury management, and cross-border settlements can now operate using shared infrastructure.

Furthermore, tokenized real-world assets (RWAs) extend these capabilities even further. Traditional assets such as treasuries and private credit are increasingly represented on-chain, leading to potential linkages between traditional cash flow mechanisms and DeFi markets. Research from CoinGecko reveals that stablecoin capitalization exceeded $300 billion by the end of March, highlighting the upward trend in tokenized assets.

Rethinking Trust in DeFi

The long-standing promotion of a “trustless” financial ecosystem in crypto may not be entirely helpful. While a smart contract removes one point of trust, it may introduce dependencies on oracles or other risk assessments. Essentially, trust simply shifts within the network rather than evaporating altogether.

The edge that DeFi provides lies in its modular nature. In traditional finance, many dependencies are tightly interconnected, whereas protocol-driven finance allows businesses to analyze, mix, and sometimes swap components without the need to rebuild complete offerings from scratch. However, this modularity also presents new risks, as each contract or protocol adds a layer of dependency.

Evaluating DeFi Applications

Merely launching a product on-chain to conform to a Web3 narrative rarely meets customer expectations. Public blockchains come with operational costs, smart contracts require careful security assessments, and regulatory frameworks can impose restrictions contrary to ideals of unrestricted access.

Therefore, my evaluation would start by examining the economics: Does the product derive significant advantages from collaborative liquidity, programmable settlement, or transparent financial operations? If a DeFi protocol provides real value through these characteristics, it deserves serious attention. If not, traditional software solutions may offer more straightforward benefits.

The most successful applications will likely strive to conceal the underlying DeFi mechanisms from users, allowing them to engage with lending products, treasury platforms, or financial markets without needing to understand the protocols facilitating these transactions. Mature infrastructure seamlessly supports user needs without drawing attention to its complexities.
