No matter if your smart contracts are on Ethereum or Substrate, our universal compatibility ensures connection flexibility like never before, enabling your smart contracts to access a w ide range of features regardless of the blockchain they are hosted on. Phala’s Phat Contracts make it possible to extend the capabilities of your smart contracts without the need for a bridge or an extra layer.
Seamless access to the Internet
Seamless access to the Internet
Phala Network doesn’t just offer unparalleled on-chain connectivity; it also bridges the gap between the off-chain world and smart contracts. The ability to send HTTP/HTTPS requests directly from your smart contracts is now at your fingertips. Take your dApp to the next level by integrating cutting-edge Web3 protocols and various Web2 API, creating a perfect fusion of old and new, on-chain and off-chain.
Advanced flexibility and performance
Advanced flexibility and performance
By offloading the computation off-chain, you don’t have to worry about costly transaction fees or network latency that hinders your progress. Experience real-time, off-chain computation at its finest, allowing you to focus on enhancing your dApp’s functionality and user experience. Run arbitrarily complex logic without any constraints, all at an affordable cost.
Computation is always verifiable
Computation is always verifiable
Phala Network is designed with multiple layers of security guarantees to provide fully verifiable computation. The network is backed by numerous decentralized workers and a significant amount of staked tokens. Phat Contracts are protected by both hardware Secure Enclaves and cryptographic evidence published and verified on the Phala blockchain, seamlessly extending blockchain-level security to the off-chain realm.

Access the unique functionalities of Phat Contract

// Send HTTP(s) requests from your Phat Contract let headers = vec![("X-Foo".into(), "Bar".into())]; let response = http_get!("", headers); assert_eq!(response.status_code, 200);
Cross-chain DEX aggregator

Cross-chain DEX aggregator

  • Cross-Chain Integration
  • Automation
  • HTTP Request

By utilizing Phat Contract, developers can create a cross-chain DEX aggregator that enables users to swap tokens between various blockchains while ensuring the best possible price and minimal slippage in one-click.

This solution employs Phat Contract to automatically search for the most efficient routes across DEXs and bridges. Then the Phat Contract initiates the necessary transactions on the target blockchains, executing swap and bridge operations on the user’s behalf. Transaction execution is further streamlined by automated schedulers and monitoring by indexers. To retrieve the status of these transactions, developers can query the indexers through HTTP requests.

It Works


Phat Contracts are deployed to the blockchain and assigned to the offchain workers, running inside Secure Enclaves. Anyone can check the signed transactions and Secure Enclave remote attestation to verify that the executed code is the one published on the blockchain.


Phat Contracts are deployed to one or more workers, grouped as a Cluster. The contracts in the same cluster are replicated to further guarantee the availability. Thanks to the redundancy by the Cluster design, the developer can further validate the states across the workers to...


Phala Network implemented end-to-end encryption during the full Phat Contract lifecycle. Secure Enclave acts as a two-way sandbox that encrypts input, output, and internet access, protecting the secrets in the enclave against software and hardware level attack.
