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.

Area of Interest

Trustless MEV

Trustless MEV refers to the concept of eliminating reliance on trusted service providers, such as Flashbot, in the Miner Extractable Value (MEV) ecosystem. Currently, 80% of Ethereum blocks are built by MEV, but the existing MEV stack depends on these trusted providers.

The problem with this approach is that it creates a single point of trust in the MEV ecosystem. Researchers have suggested using Secure Enclaves, like Intel SGX, to minimize this trust dependency.

Phala Network, an off-chain compute network powered by Secure Enclaves, can be utilized to build the MEV core stack with minimal trust assumptions. This enables a more secure and trustless MEV ecosystem for developers and users alike.

Account Abstraction

Account Abstraction is the idea of using smart contract wallets as first-class citizens instead of Externally Owned Accounts (EOAs), alongside a reliable transaction relaying infrastructure. This allows third parties to execute transactions on behalf of users, enabling features such as wallet recovery and batched transactions.

However, adoption of smart contract wallets has been limited due to the lack of a common standard for interaction between smart contracts and dApps. This results in users still relying on their EOAs for transactions.

Phala Network’s Phat Contract allows developers to create seamless user experiences by enabling registration via social accounts or gasless dApp usage. It also allows developers to sponsor transactions on behalf of users, eliminating the need for users to worry about gas fees.

L2 Sequencer

Layer 2 solutions aim to scale applications by handling transactions off the Ethereum Mainnet (Layer 1) while maintaining the decentralized security of the Mainnet. However, rollups, a popular Layer 2 solution, introduce issues like monopoly pricing, censorship, and fragmented liquidity between rollups.

Phala Network can provide a scalable and secure solution by leveraging its high-performance and confidentiality features. This enables developers to create application-tailored rollups that are fast, reliable, and maintain the composability of the Ethereum ecosystem.

Decentralized API

Decentralized APIs can enhance the trustworthiness of various services, such as Infura, Graph, Alchemy, and RPC APIs. Phala Network enables the aggregation of API services or RPC services with trustless algorithms, providing use cases like verifiable RPC aggregator switchers and trustless CDN management programs.

This allows developers to secure their websites, APIs, and Internet applications while maintaining a decentralized and trustless environment.

Web3 AI

Web3 AI refers to the integration of decentralized AI systems with blockchain technology. This enables distributed model training, ensuring data privacy while benefiting from diverse data sources. It also allows for collaborative model development, where multiple parties can work on AI models without sharing sensitive data.

Phala Network can facilitate the development of Web3 AI systems by providing a secure and transparent platform for AI model training, updates, and access. Smart contracts on Phala Network can ensure adherence to predefined rules and agreements, while the immutable nature of the blockchain provides an auditable record of these processes.

Distributed Computing

Distributed computing enables multiple computers to work together to solve complex problems, making a computer network appear as a powerful single computer. It can be used to encrypt large volumes of data, solve complex equations, and render high-quality animations.

Phala Network offers fast, cost-efficient, and secure computation by running jobs where data is generated and stored. It can streamline existing workflows without extensive rewriting by running arbitrary Docker containers and WebAssembly (WASM) images as tasks.

Gateway & CDN

Centralized CDN services can lead to issues like single points of failure, data leaks, and centralized control. Phala Network provides a decentralized content and application delivery network that accelerates the delivery of Web3 content and apps.

By connecting with decentralized storage services like IPFS, Filecoin, and Arweave, Phala Network can create a transparent, content-addressable, and publicly available CDN. This ensures a trustless, censorship-resistant, and open-source environment for content delivery.

Relayers & Validators

The relay model for cross-chain transactions abstracts data verification into a consensus problem at the relay layer. A relay chain is developed for interoperability, with relay nodes deployed in each blockchain network to monitor and synchronize transaction data.

Phala Network can help developers build inter-chain-native dApps with efficient liquidity utilization, coherent application logic, and shared states with cross-chain verifications. This eliminates the need for multiple isolated smart contract deployments on different blockchains, streamlining the development process.

How
It Works

Correctness

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.

Replicated

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...

Confidentiality

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.
