Deploy a verified allocation system for limited edition product drops, ensuring each verified customer can purchase only their allotted quantity. Cerulea assembles it from the DID and VC Ledger, Wallet Authentication, and ERC-721 NFT modules, enforcing a one-purchase-per-verified-identity limit that makes bulk scalping far harder.
Turn a bot-dominated free-for-all into a verified allocation where genuine customers get a fair shot.
01.
Admit real people, not bots. The DID and VC Ledger requires each entrant to prove a unique human identity before the drop, so automated accounts cannot flood the queue.
02.
Cap purchases per person. The contract enforces the allotted quantity per verified identity, so a single scalper cannot sweep stock across dozens of throwaway accounts.
03.
Tie the entitlement to the buyer. Wallet Authentication binds an allocation slot to a verified wallet, so the right to purchase cannot be resold or transferred before the drop.
04.
Defeat identity multiplication. Because entitlement rests on a human-unique credential rather than an email or IP, the classic scalper tactic of spinning up many accounts stops working.
05.
Allocate oversubscribed drops transparently. When demand exceeds supply, an on-chain draw assigns slots verifiably, so customers trust the outcome rather than suspecting insider access.
06.
Follow the product after the drop. The ERC-721 NFT records who received each unit, so a brand sees whether limited stock reached genuine fans or flipped straight to resale.
Follow a limited drop from identity verification through fair allocation to a purchase locked to one verified buyer.

Cerulea decomposes fair allocation into modular contracts. Each layer verifies identity, draws slots, gates the purchase, and records ownership without bots sweeping the drop.
Identity-verified fair allocation is a horizontal capability. Here is how different actors around limited drops put the shared ledger to work.
Get limited stock into genuine hands. Brands run drops with a one-per-identity limit, so a launch builds loyalty among real customers instead of enriching bots and scalpers.
Key Asset Types
Run drops customers trust. Platforms replace bot-dominated launches with verified allocation and a provable draw, restoring fairness to high-demand releases.
Key Asset Types
Get a fair shot at the drop. Genuine buyers verify once and enter on equal footing, no longer beaten to checkout by automated resale operations.
Key Asset Types
Whether you are bridging an existing commerce platform or running a native wallet-based drop, Cerulea enforces verified allocation on one shared record.
For brands and retailers on legacy e-commerce systems. Entrant verification and allocation are translated into gated on-chain purchases through the API gateway automatically.

Building an identity-gated allocation system with Sybil resistance, a provable fair draw, and one-per-identity purchase limits from scratch requires specialised engineers and long integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects drop-platform engineering benchmarks. Building human-unique verification, a provable allocation draw, and one-per-identity purchase gating for an average launch takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your allocation and limit rules into pre-audited WebAssembly binaries and provisions the allocation ledger instantly.
