Phala Networks pioneers DePIN for CPUs, optimizing performance. Decentralized compute enhances blockchain coprocessors, ensuring secure transactions. The future entails AI-Web3 synergy, with Autonomous Agents providing scalable, autonomous data processing. Phala Network distinguishes itself through its [Phat Contracts](https://docs.phala.network/developers/phat-contract), a paradigm-shifting concept in decentralized off-chain computation. The key uniqueness of Phat Contracts lies in their role as decentralized computation units, surpassing the limitations of on-chain smart contracts. These contracts run off-chain, facilitating complex computations seamlessly and cost-effectively. Unlike traditional on-chain solutions, Phat Contracts enable connections across diverse blockchains, supporting EVM and Substrate-based chains like Ethereum, Polygon, Polkadot, and [more](https://docs.phala.network/developers/phat-contract/supported-chains). Phat Contracts empower developers with a range of tools—such as the Rust SDK and JavaScript and TypeScript—providing flexibility based on their programming background. [Phat Contract applications](https://phala.network/posts/phat-contract-20-smart-contracts-now-connected) include [Zurf](https://phala.network/posts/monetizing-social-interactions-phala-and-zurf-parnership) for web3 social rewards, Phat OTP for secure on-chain authentication, Phat Strategy in GameFi, Lens Phite for [dynamic NFTs](https://phala.network/posts/Dynamic-NFT-Web3-Game-Changer), Smart Cookie for AI-driven content tailoring, and LensAPI Oracle for seamless integration of Lens data in smart contracts.

[Phala Network](https://phala.network/) is a coprocessor for blockchains. Developers deploy “[Phat Contracts](https://phala.network/phat-contract),” off-chain program for coprocessors, enhancing dApps with connectivity, internet access, and heavy computation, overcoming web3 constraints. Phala Network has one of the largest [Trusted Execution Environments (TEE)](https://docs.phala.network/developers/advanced-topics/blockchain-infrastructure/secret-key-hierarchy#key-hierarchy-management) on Intel Software Guard Extensions (SGX) hardware, which means that any code/data on Phala Network is protected from unauthorized access by users. Phala addresses developer concerns with expanded developer [language support](https://docs.phala.network/developers/build-on-phat-contract/language-basics) such as JavaScript and more, and ready-to-deploy [Templates](https://bricks.phala.network/overview) for seamless Phat Contract integration, streamlining the experience for web3 developers. Phala stands at the forefront of Web3 innovation, fostering development through its [Builders Program](https://docs.phala.network/developers/phat-contract/builders-program).
