Examples of dApps: applications and architecture
Uniswap, Compound and Decentraland illustrate exchange, lending and virtual experiences. Compare contracts, interfaces and dependencies; blockchain use does not decentralise the entire product or guarantee security.
Decentralized applications make smart contracts accessible through an interface, whether for exchanging assets, requesting loans or participating in a virtual environment. Uniswap, Compound and Decentraland illustrate different ways to connect those functions to a blockchain network.
Examining each example helps distinguish contract execution from functions that depend on the interface and other services. That separation explains user control and product dependencies; using blockchain does not make the entire application decentralized.
Applications, protocols and infrastructure
A dApp combines an interface with operations executed through contracts or programs on a network. It may depend on servers, indexers and access providers. Describe decentralisation by component rather than inferring it from a product name.
Examples for studying architecture
Uniswap documents exchange protocols and integration tools. Distinguish deployed protocols, contract versions and user interfaces. The existence of an interface does not determine every contract permission or dependency.
Compound documents collateralised lending markets. It provides a case for studying interest rates, collateral, liquidations and governance. A lending protocol is not a bank deposit and does not imply guaranteed returns.
Decentraland illustrates a virtual world with experience creation tools. Control of a digital asset must be distinguished from client rules, content, servers and intellectual property rights.
The selection contrasts three functions: exchange, lending and virtual experiences. It is not a ranking by users, volume or security. Documentation explains architecture; it does not certify suitability for every user.
Avoid mixing different roles
Chainlink supplies data infrastructure and other application services. It is not simply an end-user dApp comparable to a lending market. A browser with Web3 features does not make all its functions decentralised either.
Analysing any dApp
- Identify which operations run in contracts and which on servers.
- Review addresses, versions and administrative permissions.
- Check sources of prices, identity and other external data.
- Distinguish wallet connection, signatures and spending approvals.
- Document what happens when a frontend or provider becomes unavailable.
To build an application, start with a small, verifiable process. Blockchain development also requires integrating that architecture with the rest of the product.
