MEASURABLE RESULTS
Business Outcomes for NFT Projects
ZK-Rollup privacy-preserving airdrops deliver tangible advantages for NFT collections, from enhanced security to direct revenue growth.
01
Eliminate Sybil Attacks & Bot Farms
Our ZK proofs verify wallet eligibility without exposing user data, ensuring airdrops reach genuine holders and collectors. This protects token value and community integrity from dilution.

Technical & Strategic Comparison
Public Airdrop vs. ZK Privacy Airdrop
A detailed comparison of traditional airdrop mechanics versus privacy-preserving alternatives using Zero-Knowledge proofs, highlighting key differences in security, compliance, and user experience.
| Feature | Public Airdrop | ZK Privacy Airdrop |
|---|---|---|
On-Chain User Identity | Public wallet addresses visible | ZK-proofs conceal recipient identity |
Sybil Attack Risk | High (easy to detect & exploit) | Low (identity & eligibility are private) |
Regulatory Exposure | High (public distribution ledger) | Reduced (private claim process) |
User Experience (UX) | Simple claim, but public | Slightly more steps, but private |
Gas Efficiency | Standard (claim + transfer) | Higher (proof generation + claim) |
Developer Overhead | Low (standard ERC-20 transfer) | High (circuit design, prover setup) |
Time to Implement | 1-2 weeks | 4-8 weeks |
Audit Complexity | Standard token security | Critical (ZK circuits + contracts) |
Typical Cost | $10K - $25K | $50K - $150K+ |
Best For | Community building, low-value tokens | High-value distributions, regulatory-sensitive projects |

Frequently Asked Questions
Get clear answers on how we deliver secure, private, and compliant airdrop solutions for your token launch.
From kickoff to mainnet launch, a standard ZK-Rollup airdrop deployment takes 4-6 weeks. This includes 2 weeks for smart contract & circuit development, 1 week for internal security review, 1 week for third-party audit coordination, and 2 weeks for integration, testing, and deployment. Complex eligibility logic or custom privacy features can extend this timeline, which we scope during the initial technical discovery.
