Terra 2.0 marked a significant transition for the ecosystem, introducing a new LUNA token through an airdrop to LUNC (formerly LUNA), USTC (formerly UST), and aUST holders. This guide breaks down the LUNA airdrop calculation logic to help you estimate your allocation.
Key Airdrop Details
- Total LUNA Supply: 1 billion
- Pre-Attack Snapshot Height: 7,544,910 (May 7, 2022, 14:59:37 UTC)
- Post-Attack Snapshot Height: 7,790,000 (May 26, 2022, 16:38:08 UTC)
LUNA Airdrop Calculation Logic
1. Airdrop Ratios
Holders of LUNC, USTC, or aUST during either snapshot period received new LUNA based on fixed ratios. For example:
- Pre-Attack Snapshot: 1 LUNC = 1.034735071 new LUNA
- Post-Attack Snapshot: Different ratios applied for LUNC/USTC combinations.
2. LUNC Exchange Rates for Liquid Staking Derivatives
Derivatives like bLUNA, stLUNA, or cLUNA were converted to LUNC equivalents using predetermined rates.
| Derivative | Pre-Attack Rate | Post-Attack Rate |
|---|---|---|
| cLUNA | 1:1 | 1:1 |
| bLUNA | 1:1.5 | 1:1.2 |
3. Airdrop Allocation Formula
The final allocation was calculated using:
(Pre-Attack aUST Ratio × min(aUST Balance, 500K))
+ (Pre-Attack LUNC Ratio × LUNA Balance)
+ (Post-Attack UST Ratio × (aUST + UST Balance))
+ ... [Other derivatives]
= Total LUNA Airdropped Example: A wallet with 1,000 LUNC pre-attack and 500 USTC post-attack might receive: (1.0347 × 1,000) + (0.000015 × 500) ≈ 1,035.0075 LUNA.
FAQs
Q1: What if my allocation is less than 1 LUNA?
A: Amounts <1 LUNA were diverted to the community pool.
Q2: Were staked LUNC included?
A: Yes, bonded/unbonding LUNA balances were factored in.
Q3: How were wrapped assets (e.g., bLUNA) handled?
A: They used the rates in Table 2 (see above).
