Pi Network has launched a free RPC endpoint on its Testnet at rpc.testnet.minepi.com, enabling developers to seamlessly interact with blockchain data and build applications on its Stellar-based infrastructure. This move demonstrates a strong commitment to fostering developer engagement and accelerating smart contract innovation within the ecosystem.

Concurrently, the Mainnet's Protocol 21 upgrade was completed around April 13, enhancing network stability and laying the groundwork for upcoming features like decentralized identity. Although it missed its initial April 6 deadline, this upgrade represents meaningful, incremental progress toward Pi Network's vision of a scalable Web3 ecosystem.

Supporters commend the project's methodical development pace, while critics point to persistent delays since its 2019 launch. This ongoing tension highlights the broader industry challenge of balancing ambitious technical roadmaps with realistic execution timelines in an increasingly competitive blockchain landscape.
