Sui · SUI

A fast layer-1 chain built for consumer apps and payments

4/10
balance

A fast Move-based layer-1 where you must hold SUI for gas and a large share of supply is genuinely locked in staking — but it carries the generic-L1 narrative VCs expect to underperform, and monthly unlocks still push supply up around 1.5% a quarter.

How we judge every coin · tap

You want coins with the best chance to rise. Three forces decide it: inflation (fewer new coins = less selling pressure), narrative (a strong story pulls buyers in), business model (is the token actually needed, and used). Full method →

SUI · a hard-capped coin that still hands the market new float every month.

SUI is the native coin of Sui, a Move-based Layer 1 — ~4,074.5M circulating against a fixed 10B cap (about 41%), with more SUI staked than is currently circulating because locked coins can be staked before they vest.

Sell pressure. The staking subsidy pool paid out ~27.0M SUI and the monthly release schedule added ~42.1M~69.1M in total to the float.

Buy pressure. A stablecoin-yield buyback took ~0.5M SUI off the open market — but the coins are handed back out to ecosystem programmes rather than burned, and nothing else removes supply.

Net. About 1.68% of supply to market over 90 days, easing to 1.56% next window as both the monthly release step and the staking subsidy keep shrinking.

1. Protocol inflation
~27.0M SUI

Sui pays a staking subsidy out of a finite pool, and one epoch is one day. Every one of the last 90 epochs was read individually on-chain: 27.0M SUI actually left the pool and reached stakers. The pool held about 269.9M SUI three months ago and about 242.9M today, so the schedule and the real drawdown match to the unit — the payout is forced every epoch, so nothing can pile up undrawn. The rate steps down about 10% every 90 days; it stepped on Jul 16 2026 and steps again around Oct 14 2026, which trims the coming window to about 24.3M.

2. Vesting unlocks
~42.1M SUI

Previously-locked SUI is released on a published monthly schedule, one step on the first of each month. Three steps landed inside the window — Jun 1, Jul 1 and Aug 1 2026 — and net of the staking subsidy above they added about 42.1M SUI. Three more are due inside the next window (Sep 1, Oct 1, Nov 1 2026) for about 40.2M. The monthly step keeps easing: it was about 52M SUI on May 1, which fell just outside this window, then 23.8M, 23.1M and 22.2M. The published schedule is the same figure the market uses as circulating supply, so there is no gap here between what vests on paper and what reaches the float.

3. Foundation + unscheduled unlocks
0

About 5,925.5M SUI sits outside the float: a post-2030 tranche of roughly 5,217.2M with no release calendar at all, about 708.3M still queued on the monthly schedule to 2030, and the remaining 242.9M staking-subsidy pool. Nothing fired off-calendar in the window. Bought-back SUI, about 0.5M so far, is handed out to ecosystem programmes rather than burned or held, so it flows back to the float and is tracked here. No public evidence of release in window — monitored.

Sui is a live project with no bankruptcy estate and no trustee distribution — this row is empty by construction.

Buy pressure
1. Programmatic buyback
~0.5M SUI

Sui buys SUI on the open market every day using yield earned on its stablecoin reserves. The published purchase ledger covers Jun 22 to Aug 23 2026 and shows about 501K SUI bought for roughly $359K, averaging 8.4K SUI a day and running near 9.3K a day lately — about 0.8M if that rate holds for another 90 days. The coins are not burned and not held: they go straight back out as grants, liquidity incentives and validator support, so the buy is matched by a flow-back tracked on the sell side.

2. Protocol fee burn
0

Sui destroys nothing. Every SUI paid in computation fees over the window went straight back out to validators and stakers — the two figures reconcile exactly on-chain. Storage fees enter a perpetual fund that spends only the returns on its capital, and deletion rebates are refunds back to users. Money moves between pockets; no SUI leaves the supply.

3. Foundation buy
0

The stablecoin-funded buyback counted above is the only open-market accumulation the Sui Foundation discloses. A listed company also holds about 108.8M SUI, but it bought that on the open market as an outside investor rather than as the project — so it belongs on neither side of this ledger. No public evidence of release in window — monitored.

checked · Aug 25 2026
4. New long-term lock
0

More SUI is staked than is circulating — about 7,185.1M across 128 validators — because locked coins can be staked before they vest, so staking is not evidence of float being taken away. It is holder-driven yield seeking with a one-day exit, not an announced lock of a fixed size, and nothing new was locked away in the window.
