IPO Allotment Layer

Record every application.
Prove the allotment.

Give retail investors a transparent IPO subscription record where they can verify their application was received and see exactly how allotment was calculated. Every application and the allotment logic is anchored, so investors confirm status without relying solely on the registrar.

The Foundation

The Execution Mechanics

Turn an opaque subscription and allotment process into a verifiable, investor-checkable record.

01.

Anchored Application

Confirm receipt. The Securities Lifecycle module records each subscription application as an anchored record, so an investor can prove their bid was received.

02.

Verified Applicant Identity

Bind bids to investors. The KYC and Identity Verification module ties each application to a verified identity, preventing duplicate or benami applications.

03.

Transparent Allotment Logic

Publish the method. The allotment calculation runs on-chain, so investors see exactly how shares were allocated in an oversubscribed issue.

04.

Oversubscription Fairness

Prove the lottery. Where allotment is by lottery, the draw uses a verifiable process, so no applicant can claim the outcome was manipulated.

05.

Immutable Allotment Record

Seal the result. The Audit Logs module anchors the final allotment, so the outcome cannot be quietly changed after publication.

06.

Investor Status View

End the uncertainty. Each applicant queries their own application and allotment status directly instead of waiting for a registrar announcement.

The Subscription Lifecycle

Follow a single retail application from submission through a verifiable allotment to investor confirmation.

Smart Contract Anatomy

Cerulea decomposes IPO transparency into modular contracts. Each layer anchors applications, verifies identity, runs a transparent allotment, and exposes status without an opaque registrar step.

Applicability Across the Spectrum

IPO transparency is a horizontal capability. Here is how different actors rely on a verifiable subscription record.

Registrars & Issuers

Run subscription and allotment on a verifiable record, so investor confidence rests on reproducible logic rather than a trust-us announcement.

Network & Execution Architecture

Whether you are bridging a registrar's system or serving investors from a broker app, Cerulea routes both into one verifiable subscription record.

Track A: Registrar System Bridging

For registrars on legacy issue systems. Applications and allotment runs are translated into signed on-chain records through the API gateway automatically.

Technical Methodology

The legacy timeline reflects issue management integration benchmarks. Building anchored applications, identity binding, a verifiable allotment draw, and an investor status portal for an average issue takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your application and allotment rules into pre-audited WebAssembly binaries and provisions the subscription ledger and status view instantly.
