LUNA Airdrop Calculator

What Is the Luna Airdrop Calculator?

When the Terra blockchain collapsed in May 2022, the community voted (proposal 1623) to launch a new chain. Terra 2.0 went live on 28 May 2022 with a new LUNA token. The old chain became Terra Classic, and its tokens were renamed LUNC (old LUNA) and USTC (old UST). Most of the 1 billion new LUNA were airdropped to people who held LUNA, UST or aUST at two snapshots.

This LUNA airdrop calculator rebuilds that airdrop from your balances. It uses Terraform Labs’ published ratios, the 500,000 aUST whale cap and the 1 LUNA minimum. It also applies the vesting schedule for your tier, so you can see what you got at genesis and whether any of your airdrop is still locked today. It runs entirely in your browser, with no wallet connection and no API.

How to Calculate the Luna 2.0 Airdrop

1. Find your balance at each snapshot. For a self-custody wallet, open your Terra Classic address in a block explorer such as Terra Finder or ATOMScan and look at its balances around 7 May and 26 May 2022. Count LUNC in the wallet, staked (bonded), and unbonding.
2. Add liquid staking tokens such as bLUNA, stLUNA, LunaX, cLUNA, pLUNA, nLUNA or STEAK, converted to LUNC at the rate at the time.
3. Add aUST (UST deposited in Anchor) and, for the post-attack snapshot, plain UST.
4. Multiply each bucket by its ratio, applying the 500,000 aUST cap to the pre-attack aUST bucket.
5. Add the four results. If the total is under 1 LUNA, the allocation went to the community pool instead.
6. Apply vesting to see how much was liquid at genesis and when the rest unlocked.

The formula, in Terraform Labs’ own terms:

LUNA =  1.034735071     × pre-attack LUNC (incl. staked + LSDs)
      + 0.01827712143   × min(pre-attack aUST, 500,000)
      + 0.000015307927  × post-attack LUNC (incl. staked + LSDs)
      + 0.02354800084   × (post-attack UST + aUST)

LUNA and UST Airdrop Calculation

The airdrop was split across four buckets, each with a fixed share of the 1 billion genesis supply. Each bucket’s ratio is simply that share divided by the eligible tokens in it. That’s why the ratios look so different: the more tokens that qualified for a bucket, the less LUNA each one received.

If you held in several buckets, you got all of them. A wallet that held LUNC and aUST before the crash, and bought cheap LUNC and UST afterwards, collected from all four.

Pre-Attack vs. Post-Attack LUNA Airdrop

Before the crash about 340 million LUNA existed. By the post-attack snapshot, hyperinflation had pushed the supply to about 6.5 trillion LUNC. Dividing each bucket over those very different supplies gives two very different ratios:

• Pre-attack: 350M LUNA spread over about 340M LUNC, so about 1.03 LUNA per LUNC. Holders who were in before the depeg were made roughly whole in token count.
• Post-attack: 100M LUNA spread over trillions of LUNC, so 0.0000153 LUNA per LUNC. You needed about 65,300 LUNC to earn one new LUNA, and buyers of cheap LUNC during the crash got very little.

Holding at both snapshots counts twice. 1,000 LUNC held from April to June 2022 earned 1,034.74 LUNA pre-attack plus 0.0153 LUNA post-attack.

Pre-Attack vs. Post-Attack UST Airdrop

UST holders were split differently. Before the attack, only aUST counted, meaning UST deposited in Anchor Protocol. Plain UST in a wallet or on an exchange earned nothing from the pre-attack bucket. After the attack, all UST counted, plus aUST.

• Pre-attack aUST: 0.01827712143 LUNA per aUST, on at most 500,000 aUST per wallet. The cap limited payouts to large Anchor whales.
• Post-attack UST: 0.02354800084 LUNA per UST or aUST, with no cap.

So 10,000 aUST held on 7 May earned 182.77 LUNA. The same 10,000 still held as UST on 26 May earned another 235.48 LUNA. Remember that aUST was worth more than 1 UST by May 2022, because Anchor interest had built up. The official formula counts aUST units, not their UST value.

How LUNA Airdrop Allocation Was Calculated

Terraform Labs published the calculation logic on 28 May 2022. The main rules were:

• What counted: LUNA (now LUNC) in wallets, bonded (staked) and unbonding LUNA, and liquid staking tokens: cLUNA, pLUNA, bLUNA, stLUNA, STEAK, LunaX and nLUNA. Each was converted to LUNC at its exchange rate at the snapshot.
• aUST and UST: pre-attack aUST capped at 500,000 per wallet; post-attack aUST and UST added together.
• Excluded: wallets of Terraform Labs (TFL) and the Luna Foundation Guard (LFG) were removed from the totals before ratios were set.
• Set aside: bridged assets and holdings locked in some protocol contracts couldn’t be traced to a user at genesis. They went to the community pool to be distributed later.
• Minimum: if an address’s total came to less than 1 LUNA, nothing was airdropped and that amount stayed in the community pool.
• Exchanges: for coins held on centralized exchanges, the exchange received the airdrop and credited users under its own rules and timing.

LUNA Airdrop Snapshot Dates

Only balances at those exact blocks counted. Buying the day after the pre-attack snapshot, or selling the day before the post-attack one, left you out of that bucket.

LUNA 2.0 Airdrop Ratio Explained

An airdrop ratio is simply:

ratio = LUNA allocated to the bucket ÷ eligible tokens in the bucket

Working backwards from the published ratios shows how many tokens qualified. About 338 million LUNC pre-attack (350M ÷ 1.0347). About 5.5 billion aUST after the 500k cap (100M ÷ 0.0183). About 6.5 trillion LUNC post-attack (100M ÷ 0.0000153). And about 6.4 billion UST and aUST post-attack (150M ÷ 0.0235). Those figures match the supply of each token at the time, minus excluded wallets. The ratio converter above does this sum in both directions.

Genesis Airdrop vs. Vested Airdrop

Only part of the airdrop was liquid on day one. The rest arrived gradually through vesting accounts on the same address:

The larger tiers only apply to the pre-attack LUNA bucket. A whale’s aUST or post-attack allocations still followed the standard 30% schedule. Vesting LUNA could be staked while it was locked. To get unlocked LUNA out quickly, holders had to start undelegating about 21 days ahead, because Terra’s unbonding period is 21 days.

How to Calculate Your Remaining LUNA Airdrop

For any bucket on the linear part of its schedule:

unlocked = allocation × [ genesis% + (1 − genesis%) × elapsed ÷ vesting length ]
remaining = allocation − unlocked

Here elapsed is the time since the cliff ended (zero before it), capped at the vesting length. As of September 2026, standard allocations and the 10k–1M tier are fully unlocked. Only pre-attack LUNA wallets with 1 million LUNC or more are still vesting, at about 83% unlocked, finishing on 28 May 2027. Change the “Show vesting as of” date in the calculator to see any point in the schedule.

LUNA Airdrop Calculation Example

A wallet held 2,000 LUNC and 1,000 aUST on 7 May 2022. By 26 May it had bought 100,000 cheap LUNC and still held 500 UST:

The 2,000 LUNC is under 10,000, so every bucket follows the standard schedule. 630.32 LUNA was liquid on 28 May 2022. The remaining 1,470.74 LUNA unlocked at about 2.01 LUNA per day from 28 November 2022 to 28 November 2024. Notice how 100,000 LUNC bought after the crash earned just 1.53 LUNA.
