Pi Network's second Launchpad testnet run ends June 28, the same day the project holds Pi2Day 2026, its annual ecosystem announcement event. SLICE is an explicit testnet token; per the official Launchpad update, it "will never go onto Mainnet." Its purpose is to test the allocation mechanic that will govern real token launches across the network's 60M+ engaged users.
SLICE tests Pi Network’s Launchpad allocation design
The update addresses a measurable failure in the first Launchpad run. During the IRRA test, staking and committing were separate steps, and participants dropped off between them: 478,000 pioneers staked 36.05 million Test-Pi, but only 198,000 followed through to commit, contributing 14.72 million Test-Pi toward 10 million IRRA tokens.
SLICE collapses those two steps into one. A pioneer selects a commitment amount, and the Launchpad calculates the corresponding hold through a deterministic curve before submitting both transactions from a single screen.
Larger commitments require larger holds
The structural change is the hold formula. According to the Launchpad update, "larger commitments require proportionally larger holds, which helps preserve access for participants with smaller intended commitments."
The held Pi is not locked permanently. It "remains the participating Pioneer's Pi and is returned after the hold duration." SLICE also differs from IRRA because it connects to a live application, Slice of Pi, a Pi Ad Network game, rather than a bare testnet demo.
Pi2Day follows the Launchpad test
Pi2Day has historically marked infrastructure milestones. Pi2Day 2025 introduced AI features, Pi App Studio, and ecosystem engagement utilities. The project has not disclosed what June 28 will bring this year.
