Pi Network marked Pi2Day on June 28 by closing the SLICE token test, its second testnet launchpad round and a trial of a redesigned fair-access flow before the platform moves to mainnet. A protocol upgrade labeled v26, reported by third-party outlets as targeting scalability and security for broader Web3 adoption, had not been confirmed as activated in Pi Network's official blog as of publication.

SLICE closes second launchpad test

The SLICE token ran on Pi's testnet through Pi2Day and was tied to Slice of Pi, a gaming application that integrates Pi payments and an ad network. That made it different from Pi's first launchpad round, when the IRRA token launched on Pi Day 2026 and drew 478,000 pioneers who staked a combined 36.05 million Test-Pi.

Of those participants, 198,000 committed 14.72 million Test-Pi toward acquiring 10 million IRRA tokens. Pi said 11.71 million of the committed total was applied toward the acquisition.

Pi cited three problems from the IRRA run: users had difficulty understanding the staking-to-commitment relationship, some dropped off between the two steps, and the process had too many parameters. The network redesigned the SLICE flow around commitment amounts, automatic fair-access hold calculation, and a single confirmation screen.

Pi2Day remains Pi Network's annual release window

Pi2Day, anchored to June 28 as an approximation of 2π, is Pi Network's annual release window. The 2025 edition delivered Pi App Studio, ecosystem directory staking, and node updates.

This year's event also closed the Vibe Coder campaign, through which Pi sought to draw AI-app developers into the network with raffle prizes for participants who promoted Pi on social media.

Pi Network states it has 60 million-plus engaged users. That figure is the company's own and cannot be independently verified because Pi does not operate a public block explorer.

PI price slips 0.4%

The PI token was little changed on Pi2Day. CoinGecko showed PI at $0.1269, down 0.4% over 24 hours, with a market cap of $1.37 billion and 24-hour trading volume of $9.33 million.
