a cellar for tokens —
Brwry.
Aged on-chain. Released by time. A vintage Solana brewery where tokens sit in oak, under amber light, until the cellar agrees.

Ithe problem
01 · The Problem
Why do tokens vanish overnight?
Straight-line unlocks are a rusted lock.
One cliff, one curve, one whale. A flat pour invites anyone with a timer to empty the barrel in a single gulp — and good liquor is never made by the impatient.
The cellar remembers every rug, every deserted chart. A vesting schedule that behaves like time itself — sometimes slow, sometimes patient, sometimes held — is the cure.
IIthe method
02 · The Method
Three rooms in the cask house. Time stitches them together.
Every cask you brew follows the same physical ritual. The code is Streamflow; the voice is ours.
Let time work
Age
Tokens sit in oak, counted by on-chain time. No keys, no override. The curve breathes for weeks, quarters, or years.
Claim
Release
At the appointed hour the cask exhales. Beneficiaries tap the barrel; unreleased liquor remains under the brewer's key.
IIIaging curves
03 · Aging Curves
Five shapes of
patience.
A straight line is one cask. We cooper four more. Pick a curve or design your own — the cellar keeps a draft of each pour.
the brewer's shelf
Each preset is derived from a parameterised function of normalized time t ∈ [0,1]. Cliff is a sealed door. S-curve is a slow breath. Exponential hoards until the last minute.

Straight Pour
Time, level and unwavering.
A constant stream from first second to last. Nothing held back, nothing front-loaded.
02 · cliffcask
Aged Cliff
Sealed, then a steady pour.
The cask stays corked until the cliff passes. After that, a straight release to the end.
03 · logarithmiccask
Early Release
Young spirits run quick.
A fast start that slows to a trickle. Most of the liquor comes out early; the tail is patient.
04 · s-curvecask
Slow Start
Patience, acceleration, patience.
Almost nothing at the beginning. A burst through the middle. A soft finish at the top.
05 · exponentialcask
Late Drop
The best pour is the last.
The barrel guards its contents. Only toward the very end does the release accelerate.
Drag your own unlock curve on the visualizer. Slider a cliff, bend an S, let the exponential breathe — and preview the release hour by hour.

Your cask,
your key.
Brwry is a façade over three boring, battle-proven primitives. We don't hold tokens, we don't hold keys, we don't hold grudges — the chain does the honest work.

pillar 01
Streamflow
On-chain native vesting
Every cask is minted with Streamflow's audited program. The curve is expressed as cliff + release rate, the barrel is a deterministic account, not a custodial promise.
pillar 02
Token-2022
Transfer hooks aware
Brwry honours Solana's Token-2022 extensions. ATA derivation, transfer fee, and permanent delegate fields are wired — no surprises when the liquor pours.
pillar 03
Solana
400ms settlement
Release happens at block time. No keepers, no off-chain crons, no cosigning. The barrel opens itself when the chain agrees.
