Making use of these properties, DeFi can mitigate counterparty risk and replicate numerous financial services without the need for intermediaries and centralized platform operators. In both cases, the assets are subject to the smart contract’s rules and can be released only if the predefined conditions are met. In the context of DeFi, smart contracts are used mainly to ensure the atomic (simultaneous and inseparable) transfer of two assets or to hold collateral in an escrow account. State changes (for example, updates to account balances) are reflected on the blockchain and can be verified by anyone. All participants can observe the rules before they engage and verify that everything is executed accordingly. DeFi protocols can be designed in a way that prohibits intervention and manipulation. The code is stored on public blockchains and executed as part of the system’s consensus rules. Smart contracts are instructions in the form of computer code. Instead, these roles are assumed by so-called smart contracts. It uses public blockchain networks to conduct transactions without having to rely on centralized service providers such as custodians, central clearinghouses, or escrow agents.
