An institutional-grade executive portfolio and digital archive template designed for modern leaders, CTOs, CAOs, and enterprise founders. Crafted under Legit Creations LTD, this template features a dark-mode, grid-based layout that fuses minimalist architectural aesthetics with robust corporate infrastructure styling. It incorporates structured components like an executive dossier, corporate governance ledger, and modular multi-entity structuring to demonstrate high-level enterprise capability.

​

Why I Built It:

To provide tech founders and executives with a production-ready, highly polished web template that eliminates the friction of building an authoritative digital footprint from scratch. It delivers a clean, low-noise presentation optimized for professional positioning and institutional leadership.

Stacks Shield

Private peer-to-peer payments on Stacks Blockchain a Bitcoin Layer 2 , powered by zero-knowledge proofs.

Stacks Shield is a privacy application that enables users to shield STX and SIP-10 assets such as sBTC and USDCx, transfer value privately, split and merge shielded notes, and withdraw funds to a transparent Stacks address.

The application addresses a simple problem: blockchain transactions are publicly visible, making it difficult for users to maintain financial privacy when sending or receiving assets.

Stacks Shield uses zkSNARKs to prove that private transactions are valid without exposing the underlying note ownership and transaction details.

WHAT USERS CAN DO

Shield STX, sBTC, or USDCx into a private pool Scan for their encrypted shielded notes Transfer assets privately to another shielded address Split shielded notes Merge shielded notes Withdraw assets to a transparent Stacks address

The application has been tested end-to-end on Stacks Testnet with STX, sBTC, and USDCx.

HOW WE BUILT IT

The privacy protocol is powered by a stack of zero-knowledge infrastructure, including zkSNARK circuits, zkVerify, Stacks/Clarity smart contracts, an API, relayer, and a developer SDK.

For this challenge, we used Bubble to design and build the frontend application, creating the user interface and interaction experience that brings the underlying privacy infrastructure together into a usable product.

The goal was to make a technically complex ZK privacy system feel simple from the user's perspective: select an asset, choose an operation, and let the application handle the underlying cryptography and blockchain infrastructure.

WHY BUBBLE

One of the reasons we chose Bubble for the frontend was to focus on product experience rather than spending the challenge rebuilding UI infrastructure from scratch.

Bubble allowed us to rapidly design and build the application interface around an already-working blockchain privacy protocol and turn a complex ZK workflow into a user-facing application.

The result is a frontend where users interact with familiar payment flows while the underlying system handles shielded notes, proofs, verification, relaying, and Stacks transactions.

Hmmm the search console shows that you didn't use Bubble as a frontend at all 🤔
