    Stacks (STX) Token Unlock & Vesting Schedule

    The unlock chart above provides a clear visual overview of the Stacks (STX) token release schedule, showing when and how tokens enter circulation across investor, team, treasury, and community allocations. Understanding these tokenomics dynamics is critical for evaluating potential supply pressure, inflation impact, and market liquidity over time — key factors that can influence STX price performance.

    Each color segment in the chart corresponds to a specific allocation group described in the Allocations section below. Underlying assumptions and data models used to reconstruct this schedule are explained in detail under Assumptions, while broader utility insights and token use cases are covered in Tokenomics & Utility.

    Tokenomics & Utility

    What the STX token does

    The STX token powers the network economy. It is used to pay transaction fees, deploy and run Clarity smart contracts, register digital assets, and participate in Stacking to help secure the chain and earn BTC. Developers and users need STX for gas, similar to how ETH fuels Ethereum. (stacks.co)

    Supply and emissions

    Stacks tokenomics have evolved. Historically, some sites displayed 1.81B STX as a “max supply,” but that number was an old projection of supply by 2050. The project’s official guidance now clarifies that STX does not have a fixed hard cap; issuance is ongoing and governed through SIP (Stacks Improvement Proposal) votes. In mid‑2025, the community approved SIP‑031 to fund a five‑year endowment by adjusting emissions, with on‑chain voting thresholds set high to ensure broad agreement. (stacks.org)

    Stacking: earn BTC

    “Stacking” (with an “a”) is the consensus‑aligned way STX holders lock tokens for a set number of cycles to support network liveness. In return, they receive periodic BTC payouts sent by miners through PoX. Liquid options via DeFi protocols also exist for users who want flexibility while still supporting the network. (docs.stacks.co)

    Assumptions

    • Supply is uncapped; percentages are computed vs. the modeled total through 2050 (genesis + modeled PoX issuance through 2050 + SIP-031 emissions).

      Stacks Foundation clarified STX has no fixed max; the historic 1.818B by 2050 was an estimate, and SIP-031 adds emissions.

    • PoX mining schedule modeled using 144 Bitcoin blocks/day for tenure anchors.

      Stacks coinbase events occur per Bitcoin block/tenure; actual counts vary slightly; Nakamoto introduces faster microblocks but tenure anchoring persists.

    • SIP-029 extends 1000 STX/tenure through April 2026, then halves to 500 until April 2028, 250 until April 2032, and 125 thereafter.

      Official SIP-029 approval communicates extension to April 2026 and alignment with Bitcoin halvings; post-2026 reductions modeled to align with 2028/2032 halving years.

    • Reg A App Mining 40M tokens treated as unlocked at 2019-10-18.

      Hard fork instantiates tokens and begins unlock; program later paused. Exact month-by-month payouts not fully enumerated publicly.

    • SIP-031 Endowment emissions structure: 100M immediate, 100M 24-month vest, 300M streamed over 60 months.

      Stacks.org results + forum drafts summarize final five-year mint totaling 500M with these tranches; per-block streaming simplified to linear for charting.

    • Genesis date set to 2018-10-30 for unlock anchors.

      Official blog indicates activation at BTC block 547,921 on Oct 30, 2018; some filings reference November 2018; we anchor to the dated activation post.
