Aegis Protocol is an institutional-grade, non-custodial Web3 security and treasury application supporting 15 blockchain networks (Ethereum, Base, Arbitrum, Optimism, Polygon, Solana, Avalanche, BNB Chain, zkSync Era, Linea, Scroll, Blast, Sonic, Mantle, and Berachain). It unifies wallet hygiene, IRS/EU tax-loss harvesting, smart contract allowance firewalling, and zero-knowledge crypto inheritance into a single browser-native enclave.

ARCHITECTURE & ENGINEERING HIGHLIGHTS
Client-Side Zero-Knowledge Cryptography (InheritSafe)
Implemented native Web Crypto API (SubtleCrypto) encryption using PBKDF2-SHA256 (150,000 iterations, 128-bit cryptographic salt) paired with authenticated AES-256-GCM (96-bit IV).
Engineered a custom Galois Field GF(2^8) arithmetic engine (irreducible polynomial x^8 + x^4 + x^3 + x + 1 / 0x11B) for 2-of-2 Shamir Secret Sharing, splitting vault keys into an offline Beneficiary Share (Share A) and a Time-Locked Dead Man's Switch Share (Share B).
Multi-Chain RPC & Bytecode Security (Approval Sentinel & DustSweeper)
Built deterministic ERC-20 approve(address,uint256) (0x095ea7b3) revocation calldata encoding, BigInt wei precision math, strict Chain-ID verification guards, and independent JSON-RPC payment verification.
Engineered an automated Tax-Loss Harvesting ledger exporting CSVs (hardened against CWE-1236 formula injection) and printable IRS Form 8949 / EU MiCA certificates.
3D Holographic HUD & Aceternity UI System
Designed a custom mouse-reactive 3D perspective reactor (preserve-3d) with counter-rotating orbital telemetry rings, SVG laser conduits with animated energy packets, custom 3D isometric vector emblems, and CSS @property conic-gradient border beams.

1. Business Archetype & Profile
Business Name: Monolith Tattoo Atelier
Location: Berlin (Kreuzberg), Germany
Solo Operator: Alex Vance (Specializing in fine-line, blackwork, and sacred geometry)
Public Application Link: https://monolith-tattoo-atelier.lovable.app
2. Client Brief & Operational Quirks
Alex is a solo tattoo artist operating at peak capacity, spending 6 to 8 hours daily wearing sterile gloves with a running machine. While working, he is physically and hygienically incapable of answering calls or responding to messages.
Prior to this solution, his business suffered from three critical bottlenecks:
Instagram DM Chaos: Receiving 40+ inbound inquiries daily with vague parameters ("How much for something medium on my arm?"), creating 15+ hours of unpaid administrative back-and-forth weekly.
Unscoped Appointments: Clients cannot accurately specify dimensions in centimeters, assess placement difficulty, or identify skin contraindications (fresh scars, active eczema, moles).
Chronic No-Shows: A 28% no-show rate caused by booking calendar slots without upfront financial commitment or medical pre-screening.
3. One-Line Description of the Problem Solved
Turned vague, open-ended Instagram DMs into deposit-secured, anatomically-scoped tattoo bookings with zero manual back-and-forth from the artist.
4. Technical Architecture & Key Innovations Built in Lovable
The application solves both the "Front Door" (client intake) and the "Follow-Through" (studio management) in a synchronized dual-view architecture:
Interactive Anatomical Body Selector: Replaces vague text descriptions with a vector silhouette featuring front/back toggles, realistic contouring, and a dynamic Heatmap Pain Index that automatically flags high-sensitivity zones (ribs, neck, spine) requiring session buffers.
In-Browser Stencil Composer: Solves the primary hesitation in custom tattoos. Clients can position, scale, rotate, and preview artwork directly over their own skin using authentic 'multiply' blend modes before stepping into the studio.
Dynamic Session & Pricing Engine: Calculates exact session tiers (Quick, Half-Day, Full-Day) based on size (cm), anatomical placement difficulty, and artistic style, automatically locking compatible calendar blocks and deposit amounts.
Guaranteed Escrow & Medical Gate: Enforces a 4-point safety declaration and a non-refundable Stripe deposit checkout, reducing no-shows from 28% to 0%.
Artist iPad Back-Office & Day Sheet: A dedicated studio control dashboard displaying live synchronized appointments, escrow totals, and an iPad Day Sheet with high-res stencil specifications, medical clearances, and outstanding balances due upon arrival.
Automated DM Deflection: An integrated router configuration that deflects inbound social inquiries straight into the scoped booking funnel.
