Phala Network has solidified its position as a leading decentralized compute infrastructure provider. By leveraging a global network of over 35,000 miners, known as Workers, within Trusted Execution Environments (TEEs), it delivers unparalleled security, privacy, and raw computational power. This infrastructure is fundamental to its core innovation: the Phat Contract.
Phat Contract represents a paradigm shift in smart contract technology. It overcomes the limitations of traditional on-chain contracts by enabling seamless cross-chain communication, direct internet connectivity, and the ability to handle complex, heavy computations off-chain. This breakthrough opens up a new realm of possibilities for decentralized application (dApp) developers, allowing them to build more sophisticated and user-friendly applications.
This review covers the key milestones, product launches, and ecosystem growth that defined a transformative year for Phala Network.
Major Technical Milestones Achieved
The year was marked by significant technological deployments that expanded the network's capabilities and developer accessibility.
Phat Contract Mainnet Launch
The first quarter saw the successful launch of the Phat Contract on the Phala mainnet. This initial deployment was supported by a decentralized cluster of 150 TEE workers governed by on-chain council votes. It demonstrated immediate stability and power, processing over 800,000 off-chain requests daily.
Introduction of Phat Contract 2.0
A pinnacle achievement was the release of Phat Contract 2.0 in the fourth quarter. This major upgrade introduced a JavaScript SDK, dramatically lowering the barrier to entry for web3 developers. It established seamless, verifiable connections to any API, smart contract, or blockchain, effectively making off-chain computation infinitely more accessible.
Strategic Infrastructure Partnerships
A partnership with Polygon was a highlight, involving a global DevX tour spanning multiple continents. This initiative brought Phat Contract to developer communities worldwide through guild events, hackathons, and exclusive connect sessions, significantly raising its profile within the EVM ecosystem.
Deep Dive: The Power of Phat Contract
Phat Contract functions as an off-chain program running on Phala's secure network. It is architecturally distinct from conventional smart contracts in its use of programming languages, developer toolchains, and its core conceptual framework.
Focus on Developer Adoption
A primary goal for the year was to refine Phat Contract for ease of use. The strategy focused on two pillars:
- Lowering the Barrier to Entry: Enhancements included secure configuration for EVM chains, support for popular development environments like HardHat and Foundry, expanded wallet support (including MetaMask), and crucial JavaScript/TypeScript support.
- Leading by Example: The Phala team collaborated with top web3 projects to build real-world solutions. These successful implementations were then packaged into easily deployable templates for the broader community.
Key Use Cases and Templates
Several high-value templates were launched, providing one-stop solutions for common web3 development needs:
- LensAPI Oracle: Connects smart contracts to the Lens Protocol, a leading web3 social graph.
- VRF (Verifiable Random Function): Provides a secure source of randomness for dApps.
- The Graph Trust Score: Simplifies the integration and processing of data from multiple subgraphs.
These templates demonstrate Phat Contract's versatility in powering advanced applications, particularly in the burgeoning web3 social space.
Expanding Cross-Chain Capabilities
Phala's vision extends to creating a seamlessly connected multi-chain ecosystem, primarily through its work on SubBridge and the new inDEX application.
SubBridge: A Trustless Bridging Solution
SubBridge facilitates asset transfers between EVM chains and Polkadot parachains. In 2023, it successfully enabled the trustless transfer of over 241 million PHA tokens across 1,408 transactions. A mid-year migration to the Sygma Bridge enhanced stability, reduced fees by over 80%, and cut confirmation times in half.
inDEX: The Future of Intent-Centric Trading
The preview release of inDEX represents a leap forward in cross-chain infrastructure. Built on Phat Contract, it is an intent-centric trading application that optimizes trades across liquidity pools on different blockchains. This development moves beyond simple asset bridging to a more efficient, user-centric trading experience. A trustless execution layer was also developed to further enhance security and transparency for users moving assets across chains.

Community Growth and Decentralized Governance
As a community-driven project, Phala Network thrives on active participation and decentralized decision-making through its DAO.
On-Chain Engagement Metrics
The network demonstrated strong organic growth throughout the year:
- An average of 1,429 daily active addresses across the Phala and Khala networks.
- A steady base of 42,692 $PHA holders across all supported chains.
- A significant migration of ERC-20 token holders to native Khala and Phala blockchains, indicating growing ecosystem engagement.
Treasury and Ecosystem Funding
Phala operates without a traditional foundation, relying instead on its on-chain treasury to fund development and growth. The combined treasury of Khala and Phala is among the largest in the Polkadot ecosystem. In 2023, community governance approved over 13 million $PHA in funding, with 63% allocated directly to external ecosystem builders through programs like the Phala Builders Program.
Frequently Asked Questions
What exactly is a Phat Contract?
A Phat Contract is an off-chain program that runs on Phala Network's decentralized infrastructure. Unlike traditional smart contracts, it can connect directly to the internet, communicate across any blockchain, and perform heavy computation without incurring high gas fees, making it a more powerful and versatile tool for developers.
How does Phala Network ensure security and privacy?
The network utilizes Trusted Execution Environments (TEEs), which are secure areas on a processor. Code executed inside a TEE is isolated and encrypted, protecting it from the rest of the system, including the node operator. This technology provides robust security guarantees for verifiable computation.
What is the difference between Khala and Phala?
Khala Network was an early canary network for Phala, focusing on privacy and confidential transactions. Phala Network is the main network that has evolved into a broad decentralized compute platform, with Phat Contract as its flagship product. Both chains now contribute computational resources to the ecosystem.
Who can build on Phala Network?
Any developer can build on Phala Network. With the introduction of JavaScript support and low-code templates, the platform is accessible to web2 developers familiar with JavaScript and web3 developers from ecosystems like Ethereum, Polygon, and Polkadot.
What is the purpose of the $PHA token?
The $PHA token is the native utility token of the network. It is used for paying computation fees, staking by Workers to provide resources, and participating in on-chain governance through a decentralized voting system.
Where can developers get started?
Developers can begin by exploring the official documentation, which provides comprehensive guides. The best way to start is by deploying a pre-built template, such as the LensAPI Oracle, to understand the capabilities of Phat Contract with minimal setup.

Looking Ahead: The Future of Decentralized Compute
The past year was a turning point, transitioning Phala from a platform in development to a product-focused ecosystem. The successful launches of Phat Contract 2.0 and inDEX mark the beginning of a new chapter focused on user acquisition and product-market fit.
The core vision remains steadfast: to scale Web3 by providing the critical compute infrastructure it needs to evolve. By continuing to lower development barriers, foster a strong community, and solve real-world problems for developers, Phala Network is poised to play an integral role in the next stage of the internet's evolution. The focus for the future is clear—to build great products that are genuinely useful and drive substantial adoption within the web3 space.
