Pi Network nodes must upgrade to Protocol 21.2 by Apr 6, 2026, or risk disconnection. Protocol 21 prepares the network for Pi DEX, on-chain swaps, and future smart contracts. Pi coin trades at $0.174, nearly 78% below its all-time high as network upgrades continue. Pi Network has started its second migration phase with the mandatory Protocol 21 upgrade. All mainnet node operators must update by April 6. Missing the deadline may disconnect nodes from the network. The update also prepares the ecosystem for future Protocol 23.0 features, including smart contracts and DeFi functionality. Mandatory Protocol 21 Upgrade Deadline All mainnet nodes are required to upgrade to Protocol 21.2 before April 6. This ensures that nodes remain connected and synchronized with the network. The Pi Core Team stated, “Nodes that miss this upgrade risk disconnection from the mainnet.” Users are urged to follow official instructions carefully. Updating in time prevents network interruptions for operators and participants. Nodes that complete the upgrade now will be ready for future versions. This step helps maintain smooth operations and reduces downtime. Operators should ensure that their software runs the latest version. Meeting the April 6 deadline guarantees uninterrupted access to the Pi ecosystem. It allows node operators to participate fully in upcoming network features. Following official guidance ensures all nodes remain functional. Key Improvements in Protocol 21 Protocol 21 focuses on improving node performance and network stability. It allows the system to handle higher traffic more efficiently. Users can expect faster and safer transactions across the network. The upgrade lays the foundation for Pi DEX, a decentralized exchange for Pi and other tokens. It also enables on-chain swaps between PiUSD and ecosystem tokens. These features will expand the network’s utility for users and developers. The Pi Mainnet is upgrading to Protocol 21 – Deadline: Apr 6. All Mainnet nodes are required to complete this step before the deadline to remain connected to the network.
