A coin usually runs on its own blockchain; a token is created on an existing blockchain. Either may be used for network activity, governance, trading, lending, or collateral, and its name alone does not tell you what rights it carries. Before using one, identify the network and protocol, understand the token’s actual function, and consider the technical, financial, custody, and legal risks.
What are DeFi coins?
Decentralized finance, usually shortened to DeFi, refers to crypto-asset platforms and protocols that offer activities such as decentralized exchange, lending, and borrowing. They use distributed-ledger technology and software—often smart contracts—to carry out transactions according to programmed rules.
People often say “coin” to mean any crypto asset. Technically, however, a coin generally runs on its own blockchain, while a token is created on an existing blockchain. A DeFi service may use a network’s native coin for transaction fees and a separate token for another purpose. The term “DeFi coin” therefore describes a broad context, not a uniform product category or a promise of particular rights.
Coin versus token
- Coin: The native asset of its own blockchain. It may be used to pay network fees or support network activity.
- Token: An asset created on an existing blockchain. Its functions depend on its design and the protocol that uses it.
The SEC’s 2026 crypto-asset explainer distinguishes categories such as digital commodities, stablecoins designed to maintain value relative to a reference asset, digital tools with practical functions, and digital securities represented on crypto networks. Those categories do not mean every DeFi token fits neatly into one box. Identify the particular asset and its design rather than assuming its status from the word “DeFi.”

How do DeFi tokens work?
A token’s code and the protocol’s rules determine what it can do. Smart contracts can execute actions such as exchanging assets, recording deposits, or applying collateral rules. Users interact with the protocol through compatible software and authorize transactions with a wallet. Validators or miners help process transactions on the underlying network; “decentralized” does not mean that transactions happen without anyone performing an operational role.
Common token functions
- Network activity or fees: An asset may be needed to interact with a blockchain or pay transaction fees.
- Governance: Some tokens let holders vote on proposals or otherwise participate in protocol decisions. The practical influence depends on the governance rules, voting distribution, and who can implement approved changes.
- Trading or liquidity: Tokens may be exchanged on a protocol or supplied to a liquidity mechanism, subject to that system’s rules and risks.
- Lending and collateral: A token may be deposited, borrowed, or accepted as collateral in a lending protocol.
- Reference-asset design: Some tokens are designed to track a reference asset, but the design goal should not be mistaken for a guarantee that the value will remain fixed.
Utility is not ownership. A governance or utility feature does not, by itself, give holders company equity, a guaranteed share of revenue, or effective control of a protocol. Check the token documentation and governance design to establish what holders can actually do.

What does “decentralized” mean in practice?
DeFi aims to reduce or remove traditional intermediaries, but control and responsibility can still be distributed unevenly. Developers may write or update software; administrators or guardian keys may have emergency powers; validators or miners process transactions; and large token holders may have outsized voting influence. A protocol’s governance process can also determine who proposes, approves, and executes changes.
The U.S. Treasury’s 2022 report described DeFi platforms as facilitating peer-to-peer activity without a centralized intermediary controlling users’ funds or access, while also noting that validators and miners play an important intermediation role. That is a dated description of the report’s analysis, not a blanket statement about every protocol today. To understand a specific system, look for administrator permissions, emergency controls, voting concentration, and the process for changing its code.

What are the risks of DeFi?
DeFi risks can overlap: a software flaw may cause losses during a market downturn, while limited liquidity or unclear responsibility may make recovery difficult. The CFTC Technology Advisory Committee’s 2024 report discusses risks connected to open-source software, smart contracts, governance, oracles, and bridges, as well as liquidity mismatches and automated liquidations.
Technical and security risks
- Smart-contract flaws: A bug or design weakness can cause transactions to behave unexpectedly or expose assets to theft or loss.
- Oracle and bridge dependencies: Protocols that rely on external price feeds or cross-chain bridges depend on components that can fail or be exploited.
- Governance and administrator risk: Concentrated voting power or privileged keys can affect how a protocol operates or responds to a failure.
- Information exposure: The CFTC report also identifies harmful disclosure of personal information as a possible technology or security concern.
Liquidity, collateral, and liquidation risks
Liquidity can shrink when users want to withdraw or trade at the same time. A collateralized loan may also become unsafe if the collateral’s value falls: automated rules can trigger liquidation, selling collateral and potentially contributing to further deleveraging. A protocol’s advertised function does not eliminate the possibility of losses in stressed conditions.

Accountability and compliance risks
The CFTC report notes that unclear responsibility and limited recourse can compound harm. Treasury’s 2022 report also raised concerns that some decentralized platforms may lack customer-verification and anti-money-laundering and counter-terrorist-financing measures, creating potential compliance issues under U.S. law. That report should not be read as a current legal conclusion about every platform or user; applicable obligations depend on the facts and jurisdiction.

A crypto wallet manages the private keys used to authorize transactions; it does not store the crypto assets themselves. The SEC’s wallet explainer says that losing a private key can permanently remove access to the assets it controls. A wallet choice affects custody and convenience, but it does not make a protocol safe.

| Wallet type | Typical setup | Main trade-off |
|---|---|---|
| Hot wallet | Connected to the internet | Convenient for transactions, but more exposed to online cyberthreats. |
| Cold wallet | Typically a physical device kept offline | Generally less exposed to online threats, but less convenient for frequent transactions. |
Before connecting a wallet to a protocol, check which assets it supports, how key recovery works, and whether you understand the transaction you are authorizing. Self-custody means you are responsible for safeguarding access; using a third-party custodian shifts some custody responsibilities but introduces dependence on that provider.
How should you compare DeFi assets or protocols?
Popularity or a promised yield does not establish that an asset is suitable or that a protocol is safe. Compare the mechanics and control structure using the same questions for each option.
- Identify the network and protocol. Establish whether the asset is a native coin or a token on another blockchain, and identify the service that uses it.
- Check the function and rights. Read official documentation to learn what the asset enables and what holders can do. Do not infer rights from the token’s name.
- Review supply and distribution. Look for the stated supply, distribution, and unlock terms. Consider whether voting power or control is concentrated.
- Map governance and control. Find out who can propose, approve, and execute changes, and whether administrator keys, guardians, or emergency controls exist.
- Assess liquidity under stress. Consider whether users can transact at a reasonable size and what might happen during volatility or withdrawals. Liquidity can change; a general description cannot establish current token-level liquidity.
- Trace technical dependencies. Check whether the system relies on smart contracts, oracles, bridges, or collateral arrangements, and consider how failures in those components could affect users.
- Choose a custody approach. Consider whether you will use a third-party custodian, a hot wallet, or a cold wallet, including key recovery, supported assets, access, and convenience.
- Check the legal and geographic context. Assess the asset, offering, and services in the jurisdiction relevant to you. Seek current authoritative guidance where needed.
Are DeFi coins securities?
There is no sound way to answer that question for every asset with a single ticker-level label. In the United States, the SEC’s transaction explainer describes the investment-contract inquiry as involving an investment of money in a common enterprise, with a reasonable expectation of profits derived from the essential managerial efforts of others. The analysis can depend on how an asset was offered and the circumstances around it; some crypto assets may be offered subject to an investment contract and, in specified circumstances, later separate from it.
The SEC Division of Corporation Finance FAQs dated September 25, 2026 discuss fact-specific questions involving functionality, decentralization, and issuer representations. The FAQs express staff views, are not a rule or Commission statement, and have no legal force or effect. This U.S.-specific framing does not determine treatment in other jurisdictions, and it should not be read as saying that every DeFi coin is—or is not—a security.
