The post Pi Network launches free Testnet RPC as Mainnet upgrades appeared on BitcoinEthereumNews.com.

Developers in the blockchain ecosystem are watching closely as pi network rolls out fresh infrastructure that could reshape its growth trajectory. Free testnet RPC endpoint goes live for developers This week, Pi Network activated a new, free Testnet RPC endpoint at rpc.testnet.minepi.com, opening easier access to on-chain data for builders. The endpoint lets developers query blockchain information, run smart contract experiments, and prototype apps on the project’s Stellar-based network. Moreover, the pi testnet rpc release lowers the barrier for third-party teams that want to integrate Pi infrastructure into wallets, tools, and decentralized applications. By centralizing a reliable RPC service, the project reduces friction for early-stage testing while it continues to refine its core protocol. Mainnet completes upgrade to Protocol 21 Around April 13, the Pi Mainnet finished its transition to Protocol 21, a milestone that supporters argue is essential for long-term Web3 scalability. However, the upgrade missed its initial April 6 target date, adding another delay to a roadmap that has drawn criticism since the project’s 2019 debut. The mainnet protocol 21 update is designed to improve network stability and prepare the chain for more advanced functionality. That said, the team has emphasized that the current phase still focuses on laying foundations rather than enabling full open mainnet access. Preparing for decentralized identity and smart contracts According to the project’s communications, Protocol 21 sets the stage for future decentralized identity features and expanded pi smart contract testing capabilities. Moreover, the upgrade aims to support a broader Web3 scalability roadmap, in which user-facing utilities, applications, and security layers can be rolled out in stages. In this context, the combination of the new pi developer endpoint on Testnet and the more robust mainnet protocol is seen internally as a coordinated step. The goal is to make it easier for builders to prototype…
