DeFi as a Service (DaaS) is a broad market label for services that help businesses offer decentralized-finance features, often through APIs, wallet tools, or integrations with on-chain protocols. The label is also used for intermediary-managed strategies that put customers’ assets to work in DeFi. Those models differ in who controls the assets and bears responsibility for them. DaaS can make on-chain functions easier to access through familiar apps, but current evidence does not show that it is replacing banks or reshaping global finance at a quantified scale.
What is DeFi as a Service?
DeFi as a Service describes ways for a business to connect customers or its own operations to decentralized-finance functions without building every component itself. It is a market label, not a standardized technical product or legal category. A provider might supply a wallet SDK or API, connect an app to protocols, or manage a strategy on customers’ behalf. The name alone does not tell you whether a user retains control of their assets.

That distinction matters because a business integrating a wallet or protocol is not necessarily doing the same thing as an intermediary that selects investments and handles customer assets. The latter introduces a more direct intermediary role. Binance used this second meaning in a response to a Brazilian public consultation, describing an intermediary organizing lending, borrowing, or liquidity provision and returning agreed remuneration. That is Binance’s position in a consultation, not a regulator’s legal determination.

How does DeFi as a Service work?
A useful way to understand the technology is as three connected layers: settlement infrastructure, applications, and user-facing interfaces. The BIS’s 2023 Working Paper 1066 describes this kind of stack. Settlement occurs on the underlying blockchain; applications use smart contracts and cryptoassets to provide functions; interfaces expose those functions to users. An integration provider can help a business connect its app or wallet to the application layer.

Composability lets one protocol call or build on another’s functions. For example, a service can combine lending, exchange, or liquidity functions. That flexibility can support new products, but it also means a product may depend on multiple contracts and services rather than one provider. BIS Working Paper 1066 offers an analytical definition of DeFi as “a competitive, contestable, composable and non-custodial financial ecosystem built on technology that does not require a central organisation to operate.” It is the paper’s definition, not a universal standard—and a branded DaaS service may not satisfy every part of it.
Two common service models
| Model | What the provider may supply | Who may control assets | Evidence and qualification |
|---|---|---|---|
| Embedded infrastructure | APIs, wallet tools, or integrations that connect a business’s product to on-chain functions. | It depends on wallet design and permissions; an integration does not by itself establish who can sign transactions or move assets. | Cometh describes infrastructure for fintechs, asset managers, and corporates, including custody, staking, swaps, and smart-wallet functionality. Its documentation said the full DaaS API-layer documentation was forthcoming when accessed on 7 October 2026. Cryptum describes integrations for lending and borrowing, liquidity pools, decentralized exchanges, and yield farming. These are vendor descriptions, not independent verification of security, performance, adoption, or regulatory status. |
| Intermediary-managed strategy | Selection and operation of DeFi strategies such as lending or liquidity provision for customers. | An intermediary may have authority over some or all strategy decisions or asset movements; the actual arrangement depends on its terms and controls. | Binance described this interpretation in its response to a Brazilian public consultation. The submission is a participant’s argument, not an authoritative legal interpretation. |
What functions can be embedded?
DeFi protocols perform functions that have familiar financial parallels: decentralized exchanges facilitate trading, lending protocols connect borrowers and lenders, derivatives protocols provide exposure through contracts, and aggregators route or combine services. Policy research also discusses credit and portfolio-management applications. Similarity of function does not mean identical legal protections, governance, or risk to a bank product.
Who controls the money in a DeFi service?
There is no answer based on the DaaS label alone. Control depends on who holds signing authority, what wallet permissions exist, and whether a provider can move assets, pause activity, or change how a service operates. In a user-controlled wallet arrangement, the user may retain transaction-signing authority. In a managed strategy, an intermediary may have authority to deploy assets under its agreement with the customer. A smart wallet can also grant specific permissions without making every action wholly user-controlled.
Governance is another form of control. A project may appear decentralized while important powers remain concentrated among governance-token holders, administrators, upgrade-key holders, developers, or infrastructure operators. FATF’s 21 July 2026 report says its functional approach considers whether a natural or legal person exercises control or sufficient influence over a DeFi arrangement. The practical question is not just whether a service uses smart contracts, but who can change or direct its operation.
How is DeFi as a Service different from traditional banking?
DaaS may expose users to programmable on-chain functions through an existing financial or business app, while traditional banking typically relies on regulated institutions and their internal systems to hold deposits, process payments, or provide credit. The comparison is not one-to-one: DeFi protocols, their interfaces, wallet providers, and asset managers can play different roles, and the presence of an intermediary can make a service more or less similar to a conventional financial product.
Potential differences include how transactions are authorized, how services are composed, and where operational responsibility sits. A protocol may execute rules encoded in smart contracts, but customers can still depend on a provider’s interface, wallet, strategy choices, or support. Neither the use of blockchain nor a “decentralized” label alone establishes the legal status of an arrangement or the protections available to a user. Those depend on the service’s actual design and the relevant jurisdiction.
Is DeFi as a Service safe?
There is no blanket safety rating for DaaS. Programmability and open access can enable useful services, but they can also create dependencies and information gaps. BIS research identifies technological and economic complexity and financial-stability concerns; the European Commission’s 2022 policy report discusses potential innovation and inclusion benefits alongside pseudonymity, limited formal leadership, and constraints on supervision and control. FATF has also highlighted criminal use of cross-chain techniques and bridges.

These are questions to investigate, not assurances that any provider has answered them:
- Custody and transaction authority: Who can sign, move, or withdraw assets? Can the provider pause activity or change wallet permissions?
- Governance and upgrades: Who holds administrator keys or upgrade authority? Are emergency powers disclosed, time-delayed, or subject to independent oversight?
- Technical dependencies: Which contracts, chains, bridges, oracles, wallets, and third-party services must work correctly? What happens if one fails?
- Liquidity and exits: What withdrawal rules, fees, limits, or lockups apply? Can users exit during market stress? A quoted yield does not establish guaranteed returns or immediate liquidity.
- Compliance allocation: Which party performs customer checks, transaction monitoring, sanctions controls, recordkeeping, and incident reporting in each country?
- Fees and incentives: How is the provider paid? What conflicts, governance-token holdings, strategy assumptions, or responsibilities apply if a protocol or service fails?
FATF says its standards apply to qualifying arrangements where a person or entity exercises control or sufficient influence, and that financial institutions and virtual-asset service providers interacting with DeFi should comply with relevant Recommendations as appropriate. That does not decide the status of every DaaS product. Regulatory obligations depend on the specific service and jurisdiction, so a business considering deployment needs jurisdiction-specific legal advice.

The available figures describe DeFi activity and regulatory implementation, not DaaS adoption by banks or a measured transfer of global finance onto blockchain networks. FATF’s 2026 report cites DeFiLlama total value locked of USD 86.644 billion on 10 May 2026, compared with USD 46.86 billion on 10 May 2023. These are two point-in-time TVL observations; they are not transaction volume, revenue, or proof that traditional financial institutions adopted DaaS.
FATF reported that North America and Europe accounted for approximately 60% of global DeFi transactions, while the Middle East and Africa together were estimated at less than 10%. It also estimated that the top 20 DeFi protocols represented more than 70% of total DeFi activity. These are FATF’s reported estimates, not a permanent distribution or evidence that 20 firms control the sector. The concentration is relevant to questions about dependencies and supervisory priorities.
Regulatory implementation remains uneven. In FATF’s 2026 surveys on Recommendation 15 implementation, 132 of 143 reporting jurisdictions had not implemented FATF standards for qualifying DeFi arrangements; 2 of 142 had licensed or registered a DeFi arrangement in practice. The denominators differ, and these survey findings are not a complete census of national law.

FATF’s 21 July 2026 release also said two major DeFi-platform cyberattacks attributed to the DPRK in April 2026 involved combined proceeds of more than USD 570 million, which it described as approximately 76% of annual losses from virtual-asset hacking incidents. The attribution and comparison are FATF’s, and the figures concern those incidents and that report—not the safety record of every DaaS provider.
What this means for global finance
DaaS gives existing businesses a route to connect products with on-chain financial functions, potentially reducing the need to build every wallet or protocol integration from scratch. It also shifts complexity rather than removing it: the customer experience may be simple while the underlying service depends on wallet permissions, protocol governance, smart contracts, and providers whose roles can differ substantially.
FATF says institutional investors, virtual-asset service providers, and other regulated entities are participating more in DeFi, while DeFi remains a relatively small share of the broader virtual-asset market. Its president, Giles Thomson, said in a 21 July 2026 release: “We must stop emerging technologies being exploited by criminals trying to launder dirty money, whilst also supporting their wider adoption for legitimate purposes.” That captures the policy balance: participation is growing, but the evidence supports an evolving connection between DeFi and regulated finance—not a demonstrated replacement of banks or financial markets.
