Regulatory Area
DeFi
Decentralised finance, or DeFi, refers to financial products and services delivered through blockchain-based protocols and smart contracts rather than solely through traditional intermediaries.

- What it is
- Key things to know
DeFi arrangements can support trading, lending, borrowing, asset management, staking, derivatives, payments and liquidity provision. Some protocols are designed to operate with limited central control, but in practice many still involve identifiable developers, governance bodies, front-end operators, administrators, token holders or service providers.
The use of decentralised technology does not remove regulatory obligations. The legal analysis depends on what the protocol does, who exercises control, how users access it, what rights or assets are involved and whether identifiable persons carry on regulated activities.
Key things to know
Decentralisation is often confused with disintermediation and automation
Removing a traditional intermediary does not necessarily make a service decentralised. A product may be disintermediated or automated through smart contracts while control remains concentrated with developers, governance participants, administrators or other identifiable parties.
Some regulatory frameworks refer to fully decentralised services, but the threshold is unclear
Frameworks such as MiCAR exclude services provided in a fully decentralised manner without an intermediary. However, there is no settled definition of what is sufficiently decentralised, so firms need to assess the actual governance, control and operating structure rather than rely on labels.
Decentralisation is not a binary concept
A project may be decentralised in one area and centralised in another. The analysis should consider governance, voting rights, protocol upgrades, custody, balance-sheet exposure, revenue flows, front-end control, key dependencies and the ability to intervene in the protocol.
DAO structures can create legal and commercial risk
A DAO does not automatically remove legal responsibility. Poorly structured arrangements can expose founders, developers, token holders or governance participants to liability, while also creating difficulties around contracting, banking, tax, employment, ownership of intellectual property and regulatory accountability.
Programmable compliance can be embedded into the stack
DeFi protocols can incorporate controls such as wallet screening, eligibility requirements, jurisdictional restrictions, transfer limits and permissioned access. These controls can help manage regulatory risk, but they still require reliable data, governance, maintenance and clear responsibility for decisions.
Smart contracts create new operational and security risks
Automation can reduce manual processing, but it also introduces risks around coding errors, exploits, oracle failures, admin keys, upgrade mechanisms, governance attacks and unexpected interactions with other protocols. Firms need strong testing, monitoring, incident response and change-management controls.
