Claiming An Airdrop Shouldn’t Expose The Wallet That Earned It 🪂
Airdrops have a strange privacy problem.
The project only needs to know that you qualified, but claiming can connect the qualifying address to everything else that address has ever done.
$ARB distributed tokens to a huge group of historical users, while ecosystems around $OP have also used on-chain activity to determine eligibility and rewards.
That works because blockchain history is easy to inspect.
The same transparency also means the claimant can reveal far more than the project actually needs.
Midnight's programmable privacy enables a cleaner model:
Wallet meets snapshot conditions
→ Private data generates a proof
→ Contract verifies eligibility
→ User claims
→ Unrelated wallet activity stays protected
The important part is what the proof says.
It doesn't need to say which assets you own, how much they're worth and everywhere you've traded.
It only needs to say this user satisfied the conditions.
Crypto has become very good at measuring on-chain behaviour.
The next step is proving that behaviour happened without forcing users to publish the entire financial history behind it.
