I was tired of 10 tabs, 10 API keys, 10 subscriptions to code with AI.
So I built TEOS AI Gateway in Alexandria, Egypt 🇪🇬
WHAT IT IS:
One 11.2 MB local installer (Tauri + Rust) that gives you ONE endpoint (localhost:8082) for everything.
FEATURES:
→ 57 AI Providers: OpenAI, Claude, Gemini, Groq, NVIDIA NIM, Ollama, LM Studio +50 more
→ 11 Coding Agents Native: Claude Code, Codex, Cline, Roo Code, Aider, OpenCode...
→ Smart Auto-Fallback: if provider fails, auto-switches
→ Keys stay local: AES-256 encrypted, never leaves your machine
→ MCP Supported
→ Start FREE with NVIDIA free tier / Groq free / Ollama local
PRICING:
$39 one-time for first 50 makers (then $99) - No subscription. Lifetime.
Source included AGPL-3.0.

OVERVIEW
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.
