TradFi stands for traditional finance, the established financial system of banks, stock exchanges, fund managers and insurers. DeFi stands for decentralised finance: financial services such as loans, swaps and interest that run without a bank as intermediary, because a program on a blockchain enforces the rules. The core of the difference is whom you trust. With TradFi you trust a supervised institution; with DeFi you trust publicly visible code, and yourself.

The orders of magnitude are far apart. According to data provider DefiLlama, around $71 billion sat in DeFi applications in mid-November 2026, down from almost $121 billion a year earlier. The traditional financial system manages many times that. Even so, the two worlds are converging: fund managers are bringing fund shares onto the blockchain as tokens, and crypto exchanges in Germany operate with a banking licence or MiCA authorisation. For investors, this means that for every crypto investment you should first establish whether you are operating in the supervised part or in open code.

What is TradFi? The traditional financial system of banks, exchanges and custodians

The crypto scene uses TradFi as shorthand for everything that existed before bitcoin: current accounts, savings accounts, brokerage accounts, stock exchanges such as Xetra, funds, insurance and payment services. What these offerings have in common is a central operator that needs a licence and is overseen by a supervisor. In Germany, that is the Federal Financial Supervisory Authority, BaFin.

An intermediary is a go-between for two parties, such as the bank between saver and borrower or the broker between you and the exchange. It checks your identity, keeps the accounts, is liable for errors within its own house and is there as your point of contact. That role costs money: account fees, order fees, the spread between deposit and lending rates. In return you get safeguards such as statutory deposit protection, a complaints procedure and, in a worst case, an insolvency administrator who separates client money.

Typical features of TradFi

Opening and trading hours: Xetra trades on weekdays, and transfers pause at weekends unless an instant payment system is used.
Identity checks: without ID and anti-money laundering checks, you do not get an account.
Reversals: a wrong direct debit can be recalled, and the bank corrects a booking error.

What is DeFi? Financial services built on smart contracts on Ethereum and other blockchains

DeFi replaces the intermediary with software. A smart contract is a program stored on a blockchain that automatically executes what it specifies as soon as the conditions are met. Nobody has to approve a transfer, and nobody can stop it unless the code provides for that. Most DeFi applications run on Ethereum, alongside Solana, Arbitrum, Base and other blockchains.

The best-known building blocks are decentralised exchanges, lending markets and staking. A decentralised exchange (DEX) swaps tokens via a liquidity pool rather than a company's order book. A lending market such as Aave lends crypto against collateral that the smart contract holds and sells on its own if prices fall too far. With liquid staking you deposit ether to help secure the network and receive a tradable receipt token in return.

Which applications hold the most capital is shown in DefiLlama's ranking of November 15, 2026: at the top is the liquid staking service Lido with around $17.6 billion, followed by the bridging solution LayerZero with $16.7 billion and the lending market Aave V3 with $13.9 billion. Access is open: you need a wallet, an app or device that manages your private keys, and some crypto for network fees. You do not need an account with a provider.

TradFi vs DeFi: custody, access, costs and trading hours

The overview below sets out the main features side by side. The table describes the typical case; hybrid forms exist on both sides.

You feel the difference most in custody. At a bank, you own a claim against the institution. In DeFi you own the token directly, and whoever knows the private key can dispose of it. If you lose your wallet's recovery phrase, there is no hotline to reset access. That freedom comes at a price: responsibility for security, due diligence and record-keeping lies with you.

Deposit protection at a bank and in a smart contract: €100,000 against zero

Statutory deposit protection covers balances in current, overnight and fixed-term deposit accounts. The compensation claim is capped at the equivalent of €100,000 per customer and institution; in Germany, special cases such as a house sale are covered at up to €500,000 for a limited period. Securities in a brokerage account count as segregated assets and do not form part of the estate if the broker becomes insolvent.

There is nothing comparable for crypto in DeFi. If a lending market is hacked or a stablecoin loses its peg to the dollar, the user bears the loss. Some protocols build a safety fund from fees, but that is a voluntary reserve with no legal entitlement. Even stablecoins issued by a bank are not automatically protected: as we reported on October 29 in a piece on a bank stablecoin, crypto assets are generally not covered by deposit protection, even when a bank issues them.

DeFi risks at a glance: smart contract bugs, oracles and liquidations

Anyone using DeFi swaps the risk of a bank failure for technical and market risks. You should know the main ones before you put capital into a protocol.

Bugs in the code

A smart contract does exactly what it was programmed to do, even if that is a mistake. Attackers search specifically for such flaws. Reviews by external security firms, known as audits, reduce the risk but do not eliminate it. A protocol with several audits and a long track record without incident is considered more robust than a new project offering high yields.

Oracles and price data

An oracle is a service that feeds data from outside the blockchain into the smart contract, such as the current ether price. If the oracle delivers a wrong price, a lending market can wrongly liquidate collateral. Manipulating price sources is among the most common lines of attack.

Liquidation of loans

Anyone borrowing in DeFi deposits more collateral than they receive. If its value falls below a set threshold, the smart contract sells it automatically to cover the loan. This liquidation happens without warning and without a reminder letter. In phases like the price slide of mid-November 2026, when bitcoin fell below $66,000, it hits borrowers whose buffer was too thin.

User errors and phishing

A wrong address, a fake website or a careless approval for someone else's smart contract is enough to lose tokens. In banking, fraud checks catch some of this; in DeFi, you are your own control body.

The DeFi market in numbers: locked capital falls from $177 billion to $71 billion

The standard measure of DeFi's size is total value locked (TVL). It measures the dollar value of all crypto assets deposited in DeFi protocols. Because the deposited tokens are converted into dollars, TVL rises and falls with prices, even if nobody withdraws capital.

Within a month, DeFi has thus lost almost a fifth of its locked value, and around 42 percent within a year. Much of this is explained by the fall in the price of ether and other collateral in autumn 2026. In practice, a high yield in a DeFi pool says little as long as the value of the deposited tokens itself swings sharply.

Tokenisation of securities: where TradFi and DeFi meet in real world assets

The most interesting point of contact between the two worlds is tokenisation. A claim on a traditional financial product, such as a money market fund holding US Treasuries, is represented as a token on a blockchain. Specialists call these real world assets (RWA), real-world assets on the blockchain. You will find a detailed overview in our explainer on real world assets and their largest providers.

According to data provider Token Terminal, tokenised funds reached a market value of $37.8 billion in early November 2026, around 941 percent more than at the end of 2023. Funds holding short-dated US Treasuries make up the largest share at $13.5 billion, Crypto Briefing reported on November 10. For BlackRock's tokenised money market fund BUIDL, various data sources cite a value of between $1.9 billion and $2.7 billion.

This is where the two logics meet: the fund itself is TradFi, with a custodian, a prospectus and supervision. The token, by contrast, can be transferred around the clock and in some cases used as collateral in DeFi lending markets. Most of these funds are, however, not directly accessible to retail investors in Germany, because they are aimed at professional investors or require minimum investments in the millions.

MiCA and BaFin: how EU regulation treats DeFi in Germany

Since the end of 2024, the EU's Markets in Crypto-Assets regulation, MiCA, has applied. It requires crypto exchanges, custodians and brokers to obtain authorisation, hold capital buffers and segregate client assets. For DeFi it contains an important exemption: under recital 22, crypto services provided in a fully decentralised manner without an intermediary fall outside its scope. Our overview of the MiCA licensing obligations for crypto companies explains exactly which providers MiCA covers.

The exemption is narrow. If a company runs the web interface, holds admin keys for upgrades or can pause functions, the offering quickly counts as not fully decentralised. According to specialist law firms, a joint report by the European supervisory authorities EBA and ESMA from January 2025 concludes that only a few DeFi systems achieve this degree of decentralisation. The debate continues: France has proposed making exchanges liable for their customers' DeFi losses, as we reported on October 22.

A simple rule of thumb follows. If you buy crypto at an exchange with MiCA authorisation, you are operating in the supervised part, even though the product itself is crypto. If you connect your wallet directly to a DeFi protocol, you leave that framework. BaFin's company database lists which providers are authorised in Germany.

CeFi as a bridge: regulated crypto exchanges between the bank and DeFi

Between TradFi and DeFi lies an area the industry calls CeFi, centralised finance. This means centrally operated crypto exchanges, brokers and custodians. These providers trade crypto but hold it for you, require an identity check and are subject to MiCA supervision in the EU. For beginners in Germany this is usually the first step: deposit euros via SEPA, buy bitcoin or ether, and decide later whether to move part of it to your own wallet. Which providers are authorised is shown in our comparison of regulated crypto exchanges.

CeFi has limits too. MiCA authorisation protects you against client money being mixed with company assets, but it is no substitute for deposit protection for crypto. You always bear price risk yourself. The advantage over DeFi lies in having a point of contact, in traceability and in the tax reports that many exchanges already produce for German users.

Who is DeFi suitable for? Experience, risk budget and time

DeFi suits investors who can operate their own wallet securely, read transactions before confirming them and deliberately set aside part of their capital as a risk budget. If you only buy bitcoin occasionally and hold it for the long term, you do not need DeFi. If, on the other hand, you want to lend stablecoins, trade on decentralised exchanges or put ether to work via liquid staking, there is hardly a way around DeFi.

A sensible approach starts with small amounts. Test a protocol with a sum you can afford to lose, record every transaction and check how fees and yield actually develop. Treat yields of more than ten percent a year on stablecoins with particular caution, because they often come from leverage, token incentives or risks that only become visible under stress.

TradFi and DeFi: without deposit protection, your own due diligence counts

TradFi offers protection through supervision and liability; DeFi offers open access around the clock without an intermediary. With tokenised funds and regulated crypto exchanges, the two worlds are growing together. Two steps help you get started:

Start with an authorised exchange: buy your first coins from a provider with MiCA authorisation and SEPA deposits. Our comparison of the best crypto exchanges shows fees and licences.
Compare before you earn interest: before lending crypto, compare the terms of centralised and decentralised providers. The crypto lending comparison sets out rates, collateral and notice periods.

Frequently asked questions about TradFi and DeFi

TradFi stands for traditional finance and refers to the established financial system of banks, exchanges, funds and insurers. Its hallmarks are central operators, a licence and supervision by authorities such as BaFin.

In TradFi, a supervised institution holds and channels your money. In DeFi, smart contracts on a blockchain take over this role; you hold your tokens yourself and bear the risk without deposit protection.

Yes, private individuals in Germany are allowed to use DeFi applications. Fully decentralised services fall outside MiCA under recital 22, whereas providers with a central operator are covered.

No. Statutory deposit protection of €100,000 applies to bank deposits, not to tokens in smart contracts or wallets. The user bears losses from hacks or falling prices.
