Pi Network will deploy v23 protocol in 2026, marking an important step towards transforming into an "usable blockchain" by supporting Rust smart contracts for the first time. Although the user base has exceeded 15.8 million, the official smart contract address has not yet been announced, and the project is still in the closed mainnet phase. Pi Network is actively promoting ecosystem development, planning to expand decentralized trading capabilities, and implementing community governance. Regarding security, investors should follow official channels to obtain contract addresses and be cautious of false information online.
