Grass adds about 66M GRASS over the next 90 days — three monthly vesting unlocks of roughly 22M each on the 28th, led by the early-investor bucket — against no protocol inflation, no active burn and no real buyback on a fixed 1,000M supply. That leaves the framework at about +10.8% net. Our supply monitor reads the last 90 days at +12.36%, the same continuous vest running slightly hotter, for a gap of about 1.5 percentage points.
The verdict, in one paragraph
For the next 90-day window from June 20 2026, the MrNasdog Pressure Framework reads GRASS at about +10.8% net — supply growing steadily, driven entirely by scheduled vesting rather than by minting. Our supply monitor reads the realized last-90-day change at +12.36%, a gap of roughly 1.5 percentage points that ships a ⚠ monitor-gap chip. The gap is not a hidden flow: both the trailing window and the forward window are the same uninterrupted monthly vest — about 66M GRASS over the last 90 days and roughly 66M over the next — with no one-off cliff in either. The small difference is month-to-month variance in the linear stream, which ran a little hotter recently. GRASS is best characterised as a fixed-cap DePIN token still working through its unlocks — structurally inflationary on the active float for now, but with no perpetual issuance and a hard 1,000M ceiling behind it.
Sell pressure: where new GRASS comes from
Sell #1 — protocol inflation — is zero. GRASS has a fixed 1,000M total supply, the network mints no new tokens, and the cap cannot be raised. The roughly 45% staking yield that draws attention is paid out of pre-allocated reward buckets that already count toward the 1,000M, not freshly minted coins, so staking does not add to total supply. There is no block reward and no emission curve — the entire supply already exists and is simply unlocking on schedule.
Sell #2 — vesting unlocks — is the whole story this quarter, at about 66M GRASS. The pre-launch allocations vest on a monthly linear schedule on the 28th: the early-investor bucket (252M, 25.2% of supply) releases roughly 21M GRASS a month through its final step around October 28 2026, and the contributor bucket (220M, 22% of supply) adds a steady slice on a longer three-year vest. Three steps fall inside this window — around June 28, July 28 and August 28 2026 — for roughly 66M in total, which matches the realized run-rate of about 22M a month. Sell #3 — Foundation and unscheduled unlocks — is zero in the window: the Foundation and ecosystem bucket (228M), the future-incentives bucket (170M) and the router-rewards bucket (30M) are the standing overhang, but none has a release dated inside these 90 days. Sell #4 — long-term locked or bankruptcy — is zero, because no bankruptcy estate or court distribution applies to GRASS.
Buy pressure: where new GRASS goes
Every buy row is effectively zero, and that asymmetry is the core of the reading. Buy #1 — programmatic buyback — is carried at zero: the Grass Foundation has run a small, manual buyback funded by network revenue, about $350K disclosed across 2025 (roughly 5% of revenue), but at recent prices that is under 1M GRASS in total — a fraction of a single month's unlock. It is decision-based rather than a fixed programme, and the wallet holding the bought tokens has not been published yet, so it is tracked as scope, not booked as an offset. Buy #2 — protocol fee burn — is zero: there is no active burn, and the burn-and-mint dynamic that has been floated remains subject to governance and is not in effect. Buy #3 — Foundation buy — is zero as a separate line, because the manual open-market purchase is already captured under the buyback row. Buy #4 — new long-term lock — is zero: staking GRASS to routers and validators removes some tokens from free float, but no new fixed lockup with a disclosed amount fired in the window.
Foundation and overhang
GRASS carries a meaningful structural overhang, almost all of it on a published schedule rather than discretionary. The Foundation and ecosystem-growth bucket of about 228M GRASS (22.8% of supply), the future-incentives bucket of 170M (17%) and the router-rewards bucket of 30M (3%) are the standing reserves, none of which has a release dated inside this window. The early-investor bucket (252M) and contributor bucket (220M) are the active vesting sources behind the monthly steps; the investor bucket finishes its vest around October 28 2026, just past the window, making that the next big structural date. The buyback destination is the one opacity — the team has said it will publish the wallet addresses holding bought-back GRASS but has not yet. None of these buckets books a discretionary sell value today; each is tracked as scope. The framework re-checks the published vesting schedule, the manual buyback disclosures and the staking float on a roughly bi-weekly walk; if any reserve or buyback balance falls between refreshes, the outflow enters Sell #3 at the next refresh.
How GRASS compares to other DePIN and fixed-cap tokens
GRASS belongs to the class of fixed-cap DePIN tokens whose float is still ramping up through a multi-year vesting schedule rather than through ongoing emission. Unlike a continuous-emission proof-of-stake Layer-1 that mints fresh tokens forever to pay validators, Grass has a hard 1,000M cap and pays its staking rewards out of pre-allocated buckets — so its supply growth is purely the genesis schedule unlocking, not perpetual issuance. Unlike a halving-model coin with a fixed mining curve from day one, GRASS's near-term growth comes from unlocks, not mining, so the rate is set by a calendar rather than by block production.
Among DePIN peers, the defining feature for an inflation lens is the absence of a real demand sink. Many DePIN tokens lean on a burn — paying for the network's service destroys tokens and offsets unlocks. Grass does not burn today: dataset purchases and network usage do not yet remove GRASS from supply, and the burn-and-mint idea remains a governance proposal. That leaves the monthly vest with nothing structural pushing back against it, so the token reads as steadily inflationary on the active float even though its total supply is permanently capped. The second distinction is the buyback: where some exchange and DePIN tokens run programmatic, revenue-funded buybacks large enough to absorb unlocks, Grass's buyback is small and manual — a price-floor signal rather than a supply mechanism — and would need a large step-up in protocol revenue to matter against a 66M-per-quarter unlock.
What to watch in the next 90 days
Watch the monthly vesting unlocks around June 28, July 28 and August 28 2026, each adding roughly 22M GRASS and together forming the entire supply growth of the window. Watch the early-investor vest completing around October 28 2026, just past the window — it is the next big structural date, after which the heaviest monthly stream falls away and only the longer contributor vest continues. Watch whether the Foundation publishes the buyback wallet addresses it has promised, which would let the framework track that offset on-chain rather than via disclosure. Watch protocol revenue, since the buyback only becomes a real counterweight if revenue scales enough to fund larger purchases. And watch any governance move to activate a burn-and-mint or fee-burn dynamic, which would be the first genuine buy-side mechanism the token has.
Summary
GRASS is a fixed-cap Solana DePIN token still working through its vesting schedule. The next 90 days add about 66M GRASS — three monthly unlocks of roughly 22M each on the 28th, led by the early-investor bucket — against no protocol inflation, no active burn and only a tiny manual buyback, leaving the framework at about +10.8% net. Our supply monitor reads +12.36% over the trailing window, but that is the same continuous vest running slightly hotter, not a forward rate or a hidden flow. The key risk ahead is that there is no structural demand sink to offset the unlocks; the structural backstop is the hard 1,000M cap, which means today's inflation is a float story, not an unlimited-issuance one.
