Definition ∞ Single-Contract Architecture refers to the design choice in decentralized application development where an entire application’s logic and data reside within a single smart contract on a blockchain. This approach simplifies deployment and interaction, as all operations are managed by one address. However, it can also present limitations regarding upgradeability, gas costs, and potential security vulnerabilities if the contract is not rigorously audited. It offers a straightforward deployment model for simpler decentralized applications.
Context ∞ Discussions around Single-Contract Architecture often contrast its simplicity with the modularity and flexibility of multi-contract designs, particularly for complex decentralized finance protocols. While suitable for smaller, static applications, its limitations in scalability and upgradability are frequently debated. News regarding smart contract audits, security exploits, or new protocol designs often evaluates the trade-offs associated with this architectural choice in terms of risk and development ease.
