Instadapp is a comprehensive DeFi middleware platform designed to simplify and enhance decentralized finance interactions for both users and developers. At its core, Instadapp provides a 'DeFi Smart Layer' (DSL), an upgradable smart contract wallet system that aggregates multiple DeFi protocols into a single composable and extensible interface. This architecture allows users to manage complex DeFi operations through one smart account, reducing friction and improving security by isolating interactions within a non-custodial smart contract wallet.

The platform supports a wide range of DeFi protocols across multiple EVM-compatible chains including Ethereum Mainnet, Polygon, Avalanche, Arbitrum, Fantom, and Optimism. Instadapp’s smart accounts use a modular extension system governed by the community, enabling continuous upgrades and new functionalities such as flash loans, authority management, and Layer 2 support. Developers can build on top of Instadapp’s DSL by creating custom connectors and extensions, leveraging the cast() function to execute complex, multi-step DeFi transactions atomically.

Instadapp stands out by offering a highly composable and upgradeable smart contract wallet that acts as middleware between users and underlying DeFi protocols. This reduces the complexity of interacting with multiple protocols individually and mitigates risks like front-running and flash loan attacks at the wallet level. The platform’s governance model ensures ongoing maintenance and evolution of the protocol, fostering community collaboration. Instadapp’s developer-friendly documentation, active Discord community, and open-source codebase facilitate rapid integration and innovation.

To get started, developers can follow the detailed installation and setup guides in the official documentation, experiment with the cast() function for transaction execution, and explore existing connectors for popular DeFi protocols. Instadapp also offers products like Instadapp Pro, Avocado wallet, and Fluid protocol to extend user capabilities. The platform is well-suited for DeFi developers, infrastructure teams, financial institutions, and DAO tooling projects aiming to build scalable, secure, and composable DeFi applications.
