Pi Network upgrades to Protocol 20, enabling smart contracts, dApps, and improved blockchain infrastructure for its growing ecosystem.
Pi Network has upgraded its Mainnet blockchain to Protocol 20, marking a key step in its development roadmap.
The update prepares the network for smart contract functionality, enabling developers to build decentralized applications while improving infrastructure, scalability, and readiness for broader ecosystem growth in the evolving Web3 environment.
Pi Network Completes Protocol 20 Upgrade
Pi Network has completed its upgrade to Protocol 20 across its Mainnet blockchain and node network.
The update aligns all major nodes with version 20.2, ensuring system-wide compatibility. This step forms the base for enabling smart contract capabilities on the network.
All major Pi nodes have now been upgraded to version 20.2 and are supporting protocol 20. Pi has also completed the upgrade of its Mainnet blockchain to protocol 20.

The upgrade follows earlier versions released in stages during early 2026. These included v19.6, v19.9, and v20.2.
Each release prepared the system for the final transition. Node operators were required to update their systems before a set deadline to maintain network stability.
The blockchain now runs on stellar-core 20.2.0, which improves performance and security.
The system remains based on the Stellar Consensus Protocol. This allows efficient validation and coordination across distributed nodes.
The development team stated that smart contracts will be introduced in phases. These phases will focus on practical use cases.
Categories such as subscriptions, escrow services, and digital assets are among the first expected features.
Smart Contracts Support Utility Driven Applications
Protocol 20 enables programmable logic on the Pi blockchain. This allows developers to build decentralized applications, also known as dApps.
These applications can automate transactions based on defined conditions. The rollout of smart contracts will follow a structured process.
Each contract will go through external audits before release. After review, it will be tested on the Testnet. Only then will it move to the Mainnet.
The network plans to prioritize applications tied to real services. Subscription-based contracts are expected early, as they reflect common business models.
Other features may include NFT support and marketplace transactions.
Pi Network stated that “smart contracts are programmable logic executed on the blockchain.”
This function allows systems to run without intermediaries. It also supports new types of digital services within the ecosystem.
The update also requires changes to supporting tools. The Pi Wallet and Pi SDK will be updated to handle smart contract interactions. These updates aim to provide a smoother user experience.

Ecosystem Expansion Supported by Launchpad Tools
Alongside the protocol upgrade, Pi Network introduced its Launchpad on the Testnet.
The platform allows projects to issue ecosystem tokens linked to real applications. These tokens are designed for product use rather than fundraising.
Projects must have working applications before launching tokens. This ensures that tokens have immediate use within their platforms.
Token functions may include payments, access, rewards, or governance features.
The Launchpad also directs Pi proceeds into liquidity pools. This structure supports trading activity and helps stabilize token availability.
It also prepares the system for future decentralized exchange operations. Developers can use the Launchpad to test products and gather user feedback.
The network’s large user base offers early access to real participants. This helps projects refine their services before wider release.
Pi App Studio now supports Mainnet integration for selected apps, enabling live Pi transactions.
This allows creators to build services within the active blockchain environment. With over 16 million users migrated, the network has a strong base for growth.
The Protocol 20 upgrade supports a programmable system, with smart contracts and ecosystem features expanding gradually.
