UNI Tokenomics: How Supply, Genesis Buckets, and Mint Authority Work

When a token launches, the number on a price page and the number in a launch post are rarely the same picture. One is a live count of coins that can move, and the other is how many were created and labeled on day one, so mixing those two is how a widget becomes the supply.

That mix-up has a cost, because people size a holding from a fully diluted headline, or they treat a community percentage as coins sitting in user wallets today. A later mint right and an early mining program can share a percentage and still be different piles.

Tokenomics is the labeled split of that creation event: who received coins, when those coins could move, and whether anyone can mint more later. Circulating supply stays a dated snapshot you look up when you need it.

UNI's tokenomics is a genesis mint of 1,000,000,000 UNI, a community 60 percent that is three buckets added together, a four-year vest that ended in September 2025, and an unused right to mint up to 2 percent a year. What Uniswap is names the protocol those buckets belong to. What the UNI token is names the vote coin.

How the one billion was split

At genesis, Uniswap minted 1,000,000,000 UNI and assigned that pile to named buckets, with community members receiving 60 percent. That 60 percent is three slices added together: a treasury, an airdrop, and an early liquidity-mining program.

Suppose you buy 80 UNI on a venue as a first size. Those 80 coins are a transfer of coins that already sat in some genesis bucket, so your holding is a transfer, and the buckets below are the original split.

1 billion UNI have been minted at genesis and become accessible over the course of 4 years. 60.00 percent to Uniswap community members is 600,000,000 UNI. Team members and future employees received 21.266 percent (212,660,000 UNI) with 4-year vesting. Investors received 18.044 percent (180,440,000 UNI) with 4-year vesting. Advisors received 0.69 percent (6,900,000 UNI) with 4-year vesting (source: Uniswap Blog, Introducing UNI).

The UNI token docs split the same 60 percent into slices a reader can check. Community treasury 43.00 percent is 430,000,000 UNI. Historical users and LPs, as an immediate airdrop, 15.00 percent is 150,000,000 UNI. The remaining 2.00 percent is 20,000,000 UNI for the initial liquidity-mining program that ran from September to November 2020.

Those six buckets add to 100 percent of the genesis one billion, and the first three buckets are the community 60 percent. Docs round team and investor shares to 21.27 percent and 18.04 percent, while the genesis post shows the extra decimal, so use either rounding, because those six buckets already close the pie.

The 15 percent airdrop was claimable by historical liquidity providers, Uniswap v1 or v2 users, and SOCKS holders, from a snapshot ending September 1, 2020, 12:00 am UTC. SOCKS holders were a thin slice inside that 15 percent. The 20,000,000 UNI mining program is also inside the 60 percent, and it is a different pile from the unused annual mint in a later section.

Keep one picture: 1,000,000,000 UNI were created once, then labeled, and your 80 UNI skipped adding a bucket. Buying those coins on BloFin or swapping them in a pool moves coins that already had a 2020 label, which is why a 2026 fill is a transfer.

Vesting that ended in September 2025

Most of that one billion was spendable only after a wait. Treasury UNI, plus team, investor, and advisor UNI, sat behind a four-year vest, which here is a time lock on those buckets. It leaves your 80 UNI free if you bought them on a book in 2026, and it leaves a coming tape event as a separate headline.

Governance first gained access to vested treasury UNI on October 18, 2020, 12:00 am UTC, after a 30-day cliff. The treasury then released on a front-loaded four-year calendar: year 1 was 172,000,000 UNI, year 2 was 129,000,000 UNI, year 3 was 86,000,000 UNI, and year 4 was 43,000,000 UNI. Those four lines add to the 430,000,000 UNI treasury bucket. Team, investor, and advisor allocations used the same four-year schedule.

The UNI token docs date the end of that vest, and the technical reference names the contracts that paid treasury UNI across those years. Vested UNI to the protocol treasury over a four-year period beginning September 2020 and ending September 2025 is the technical-reference entry for those vesting contracts (source: Uniswap Docs, governance technical reference).

Airdrop UNI and the initial mining UNI sat off that vest. The genesis post says those mining UNI skip vesting or lock up. Your 80 UNI, if you bought them on a book in 2026, were already past that calendar. Vesting-ended is a fact about the original team, investor, advisor, and treasury buckets.

What matters here is the date the docs name. Genesis described a four-year vest, and current docs name September 2025 as the end, so quote both dates. Subtracting them into a fifth year is a calendar error.

The liquidity-mining 2 percent and the unused mint

UNI has two different 2 percent lines, and mash-ups treat them as one faucet. The first 2 percent is already inside the genesis one billion, and the second is a later right to create extra UNI. Only one of those ran as a program, while the other has stayed unused.

The first line is 20,000,000 UNI, which is 2 percent of 1,000,000,000. It funded the September 18, 2020 to November 17, 2020 liquidity-mining program on four Uniswap v2 pools, at 5,000,000 UNI per pool. Those coins were genesis coins, so mining them left the cap in place and moved a labeled slice to LPs.

The second line is mint authority after the four-year genesis window. After the four-year genesis window, the 2020 post described a planned perpetual inflation rate, while current UNI docs treat that plan as inactive. Governance has authority to mint up to 2 percent of total supply annually and has left that right unused to date. Team, investor, and advisor allocations vested on the same four-year schedule, and all vesting concluded in September 2025 (source: Uniswap Docs, UNI token).

Both documents can be true as dated records, because the genesis post described a 2 percent yearly inflation rate that would start after four years. The docs now describe inflation as inactive, and they describe the 2 percent mint as unused, so read that 2 percent as unused authority.

Your check is small enough to keep on one screen. If the 2 percent is 20,000,000 UNI already assigned at genesis, it is the mining bucket, and if the 2 percent is a yearly ceiling on extra UNI, it is mint authority, which makes those different piles.

UNI governance is the page for what a vote can change, including that unused mint as a knob. The ceiling still needs a passed vote before extra UNI exists.

Mint authority after vesting ended

Mint authority is real, and a calendar drip is missing, so vesting-ended leaves the unused mint off. A mint would need its own passed vote, then the same delay any other onchain action uses. Until that vote exists, total supply at launch stays the genesis 1,000,000,000 UNI, minus coins later destroyed, plus nothing from that unused ceiling.

Mint authority is a cap on extra UNI, up to 2 percent of total supply in a year. It is a different thing from a 2 percent coupon you collect, and a different thing from a refill of coins already burned. If a later vote authorized a mint, that would add new UNI up to that year's cap, and it would leave a burn address unreverted. The UNI token contract comments a cap on the percentage of totalSupply that can be minted at each mint and sets mintCap to 2, with minting allowed only by the minter address (source: Uniswap governance, Uni.sol).

The unused mint is a ceiling, and the docs' own line is that governance has left the right unused.

Burns are a different supply path, and since December 2025, protocol fees can be used to burn UNI. Protocol fees are a portion of swap fees directed to the protocol rather than to LPs, so that path can shrink supply (source: Uniswap Docs, Fees). A live burn total is a tracker figure, rather than a genesis bucket. UNI burns and the fee switch walks TokenJar and Firepit. Holders still have no pro-rata claim on protocol revenue, and a burn leaves your 80 UNI undeposited.

Tally proposal 100 is executed, and it activates v4 protocol fees on a subset of pools after v2 and v3 fees on the listed chains. Official fee pages can lag, so treat those settings as current, while they still skip being a circulating figure (source: Tally, Uniswap proposal 100).

The idea to carry forward: vesting-ended closed the original lock on team, investor, advisor, and treasury buckets, and it left a mint unstarted. Extra UNI still waits on a vote that has stayed uncalled.

Circulating supply and the genesis one billion

Circulating supply is a live tape, and genesis is a historical mint. Mixing them is how a price page's widget becomes the UNI supply. Circulating moves when coins are claimed, spent from treasury, burned, or stuck in a contract a tracker still counts. Genesis 1,000,000,000 UNI stays put because you bought 80 UNI.

The cutoff for that live tape is September 2026. CoinGecko and CoinMarketCap circulating numbers stay off the genesis table, because those figures change and baking one would go stale in the same week. If you need the tape, open a tracker at the time you care about, and remember it is a different figure from the genesis table.

Your 80 UNI can sit in three places that trackers treat differently. In a signing wallet they are usually counted, on BloFin as UNI/USDT spot they are a venue credit of the same token, and as UNIUSDT they are a price position rather than coins.

BloFin has listed UNI/USDT on spot since January 15, 2024. BloFin lists two UNI perpetuals: UNIUSDT at up to 75x, listed January 12, 2023, and UNIUSD, an inverse contract settled in UNI, at up to 20x, listed June 27, 2025.

Uniswap is a competing decentralized exchange (DEX), and BloFin is a centralized exchange that lists UNI. The generic fork of custody and matching is centralized versus decentralized exchanges. A listing date tells you when this centralized-exchange market went live. It leaves UNI unminted, and it leaves the genesis buckets in place.

Bridged UNI on another network is still UNI as a token on that network's contract. Adding chain copies into a new genesis cap double-counts coins that already sat in the 2020 table.

Hold on to one thing: circulating is a snapshot with a date, and genesis is the 1,000,000,000 UNI table, so keep the table and leave the snapshot off.

What to weigh before you treat supply as a price story

Treat UNI supply as labeled piles first, then check which figure a screen is actually showing. A fully diluted 1,000,000,000 UNI headline, a community 60 percent slide, and a circulating widget are different things. Your 80 UNI only count in the pile that actually holds them.

You can skip memorizing the six genesis buckets, so carry four checks.

• If the screen says total or max supply near one billion, ask whether it is the genesis mint, because that number is the 2020 creation event.
• If the screen says 60 percent community, ask whether it means treasury plus airdrop plus mining, because those three buckets are the 60 percent.
• If the screen says 2 percent, ask which 2 percent, because 20,000,000 UNI already mined is a different pile from the unused yearly mint ceiling.
• If the screen says circulating, ask for the timestamp, because the cutoff is September 2026 and the tape stays unpublished.

What moves the UNI price covers fee burns, listings, and how UNI often moves with ETH, and those movers skip being a substitute for the genesis table. ETH tokenomics is a different issuance path: ETH was created on a different schedule from a one-billion governance mint with a 60 percent community bucket.

Walk one screen with those checks, and if you see 1,000,000,000 UNI, you are looking at genesis. If you see a 2 percent line with no year and no 20,000,000 UNI, you still have to split mining from mint authority. If you see a circulating widget, you are looking at a live tape.

The honest close is small: size the holding after you know which supply figure you actually wanted.

Frequently asked questions

If I added UNI and ETH to a v2 pool in 2026, can I still claim the 5,000,000 UNI mining slice?

That 5,000,000 UNI per pool was paid only during the September 18, 2020 to November 17, 2020 window, on four named Uniswap v2 pairs, so later LP inventory leaves that genesis slice closed. Fees you earn now stay in the pair as extra reserves, or on a later-version position. They skip leftover mining UNI, and they skip mintCap printing coins into your wallet. A 2026 deposit is a share of today's pool.

If a former team member sends me 80 UNI in 2026, is that newly minted supply?

Vesting-ended made those genesis coins transferable, so a wallet send moves UNI that already sat in the 1,000,000,000 table. MintCap is a separate contract right, and only the minter address can call it after a passed vote and delay, so a personal transfer skips that call. The received 80 UNI raise your balance, and they leave totalSupply unchanged.

If I provided UNI and ETH on Uniswap v2 in September 2020, was that one of the four mining pools?

Those mining rewards went to four Uniswap v2 pairs only: ETH/USDT, ETH/USDC, ETH/DAI, and ETH/WBTC. A UNI/ETH deposit, even in September 2020, sat off that list. Fees on UNI/ETH accrued in that pair the ordinary way. You leave a UNI/ETH position as UNI/ETH. The program paid 5,000,000 UNI per listed pair, and only during its 2020 window.

Does closing a UNIUSD position mint or burn genesis UNI?

UNIUSD is an inverse perpetual, so PnL settles in UNI as a venue claim, then as coins only if you withdraw. Closing the position is a book fill, so it leaves mint uncalled on the genesis contract, and it leaves the 1,000,000,000 UNI table in place. A 20x cap on that market is a product setting, and spot UNI/USDT remains the product that withdraws.

If a mint vote passed, would my UNI/USDT line on BloFin increase by itself?

Uni.sol lets only the minter address mint, and those new coins land in the address the vote names. A BloFin UNI/USDT line is a venue book until you withdraw, and support leaves a governance mint outside that line. You would see extra UNI only if someone later sent you some of the minted coins, which is a transfer after the mint, so closing UNIUSDT still skips collecting it.

Are treasury UNI still part of the community 60 percent after they vest?

The 60 percent is how the 2020 split was written: treasury, airdrop, and mining. Once treasury UNI vested, governance could spend them on grants and programs. Spent UNI sit outside a treasury balance even though the original pie chart still says 43 percent, so check the allocation table for history, and check a tracker, at your own date, for where coins sit now.

If I first swapped on Uniswap in 2021, can I still claim the 15 percent airdrop?

The airdrop used a snapshot ending September 1, 2020, 12:00 am UTC. A wallet that first showed up in 2021 sits outside that snapshot, even if it later holds UNI. Historical LPs, v1 or v2 users, and SOCKS holders were the eligible sets at that date. A 2021 first swap skips a missed airdrop you can backfill, and it skips a mint. Keep the 15 percent as a 2020 claim window.
