DeFi vs CeFi vs TradFi: how do they differ?

The difference between TradFi, CeFi and DeFi is who provides the service and where the records are kept. The BIS puts the line between the two crypto forms this way: it "lies in whether the financial service is automated via smart contracts on a blockchain or is provided by centralised intermediaries".

The deposit cover of EUR 100,000 comes from Article 6(1) of Directive 2014/49/EU. The leverage row follows BIS data from 2021, before MiCA applied. The BIS also finds that DeFi "provides users with much greater anonymity than transactions in CeFi or traditional finance".

TradFi is short for traditional finance, meaning the banks, insurers, exchanges, fund managers and payment firms that work under a license and keep client records in their own systems. This is the usual TradFi definition, and the BIS table uses it as the reference for the other two. Loans rest on a credit assessment, and the deposits of a bank client are protected up to EUR 100,000.

In the BIS comparison, TradFi is also the only one of the three with shock absorbers. DeFi "lacks internal shock absorbers, such as banks, that can provide liquidity at times of stress".

CeFi is crypto finance through a company that holds the client's assets and records, such as a centralized exchange. Centralized finance examples are crypto exchanges and crypto lending platforms. When people compare decentralized finance vs centralized finance, the difference between them is that company. In CeFi the client trusts the provider; in DeFi the client trusts the code of a smart contract.

The line also runs through stablecoins. The BIS notes that "the majority of stablecoins are CeFi" because a designated intermediary manages issuance, redemption and reserve assets. DeFi stablecoins such as DAI are managed on-chain and rest on a pool of crypto-assets worth more than the coins in circulation. To the extent that DeFi relies on CeFi stablecoins, the BIS writes, "it remains dependent on CeFi and traditional finance".

The pros of DeFi are automation and open records; the cons are the risks that come without a responsible intermediary. DeFi digitizes and automates contracts, which could reduce intermediation layers, "according to its proponents" (BIS). Every transaction is visible on the chain.

On the other side, the European Securities and Markets Authority (ESMA) sees "serious risks to investor protection" in DeFi, among them "the lack of a clearly identified responsible party" (ESMA, October 11, 2023). CeFi has that party. Under MiCA the provider needs an authorization and must keep client crypto-assets apart from its own, so its creditors cannot reach them. The price is trust in one company.

DeFi lending runs through a protocol with automatic liquidation; CeFi lending runs through a platform that holds the client's assets. In DeFi, loans are overcollateralized and the protocol sells the collateral when the collateral ratio falls below a threshold (BIS).

MiCA does not yet set specific rules for crypto lending. Article 142 asked the European Commission for "an assessment of the necessity and feasibility of regulating lending and borrowing of crypto-assets" by December 30, 2024.

In Europe, and so in Germany and Austria, the three forms fall under different rules. TradFi firms hold licenses under banking and securities law, supervised by BaFin in Germany and the FMA in Austria. CeFi providers need an authorization as crypto-asset service providers under MiCA, which applies directly. Fully decentralized services without an intermediary fall outside MiCA under recital 22; whether a service has an intermediary is a question for the single case.

The European Central Bank, based at Sonnemannstrasse 20 in Frankfurt am Main, compared DeFi with traditional finance in its Macroprudential Bulletin of July 2022: "The main distinguishing feature is that these services are provided without central intermediaries." The same article found that "1% of the total token holder addresses hold around 97% of the total governance token supply" (ECB, July 2022).

Switzerland is outside the EU, so MiCA does not apply there. FINMA supervises banks and securities firms under Swiss law and judges tokens by their "economic function and purpose" (FINMA, February 16, 2018). This page gives no legal advice.
