Whitelist Check
Cross-chain utility for managing NFT whitelist signatures and secure allocation verification for launchpads.
- React
- Ethers.js
- Express
The Problem
Launchpads needed a reliable way to verify whitelist signatures and allocations across chains without exposing private keys or relying on manual spreadsheets.
Errors at launch time are costly; verification had to be deterministic and auditable.
Tech Stack & Architecture
React frontend with Ethers.js for signature verification and an Express backend for secure allocation checks.
Sensitive signing material stays server-side; the client only presents proofs and status.
Key Results / Business Outcome
Delivered a cross-chain whitelist verification utility used for secure allocation checks at launch time.
Teams reduced manual list handling and clearer failure messages when a wallet was not allocated.
