Daniel Edward Mwihoti
I build Bitcoin, Cardano, and AI systems — in Rust, Python, Next.js/React, and TypeScript. Fullstack, backend, and open-source contributions.
About Me
I'm a Bitcoin, Cardano, and Rust engineer based in Nairobi, Kenya. I build cryptography and consensus systems — secp256k1 wallets, Plutus smart contracts, on-chain games, and AI-augmented developer tooling.
I'm an open-source contributor to IntersectMBO's lsm-tree (Haskell, used by the Cardano node), the Cardano Foundation, and rust-bitcoin. I also ship full-stack — Next.js, Supabase, Postgres — when the project calls for it. Open to remote contracts and collaborations.

Projects
Selected work in Bitcoin, Cardano, Starknet, AI, and full-stack.
Stacks builders and founders need a trusted way to find co-builders, with partnerships verifiable on-chain rather than just word-of-mouth.
StackMate
Builder-partner marketplace on Bitcoin L2 (Stacks). Project owners post partner requests; builders browse, apply with a pitch, and get accepted — every key action (registration, application, acceptance, mutual endorsement) is anchored on-chain via four Clarity smart contracts on Stacks mainnet (Nakamoto epoch 3.4). Off-chain Postgres handles search and metadata; on-chain principals form the verifiable reputation trail.
AI agents need to sign blockchain transactions without ever exposing raw private keys.
Open Wallet Standard
Multi-chain AI agent wallet supporting 9 chains (EVM, Solana, Bitcoin, Cosmos, XRPL+). Policy-gated signing tokens — AI agents never hold raw keys. Includes Solana + EVM signature verification and live testnet transactions.
Show exactly how Bitcoin works at every layer — from key generation to signed, broadcast transactions on testnet.
Bitcoin Wallet Lab
Educational Bitcoin wallet on testnet4 built on what I learned from Bitcoin Dojo. Generate all three address types (P2PKH, Nested SegWit, Native SegWit) from a single key, receive testnet coins, build and sign a real transaction, then broadcast and watch it confirm on-chain. secp256k1 + ECDSA + RFC 6979 implemented from scratch in a vendored bitcoin_dojo crate. Includes signature malleability demo.
Give institutions a tamper-proof way to issue and instantly verify credentials without a centralised authority.
LiteCert — Blockchain Certificate Verification
Certificate verification platform anchored on the Cardano blockchain using Mesh SDK. Institutions issue digital credentials with unique identifiers (e.g. CAR_JOH_01); employers verify instantly via on-chain transaction hash. Privacy-first: certificate data is hashed before blockchain submission.
Build a fully on-chain game for the Dojo Game Night hackathon, accessible via Telegram without crypto knowledge.
Memorabilia
Fully on-chain memory card matching game on Starknet, built for the Dojo Game Night hackathon. Playable as a Telegram Mini App (@enter_memorabilia_musem_bot) — no wallet or gas fees to start. Features Account Abstraction, gasless transactions, 3 eras, 15 levels, daily challenges, and NFT minting via Cartridge.
Build exercise habits through daily accountability, community support, and on-chain proof of progress on Avalanche.
Daily Habit Hub
Modern fitness tracking app combining social accountability with Web3 rewards. Daily check-ins across gym, running, cycling, yoga and more. Visual streak tracking, community feed, professional coaching connections, and $HABIT token rewards + "Proof of Progress" NFT minting on the Avalanche network.
Real-time vehicle speed, traffic jam detection, and person tracking at the edge with zero cloud latency.
Computer Vision — Traffic & Attendance
Edge-native CV system for real-time traffic sensing and multi-class object counting. Dual-stack architecture: Python (Ultralytics + DeepFace for gender analysis) for prototyping, and Rust (ort/ONNX Runtime + OpenCV) for high-performance edge inference. Homography-based pixel-to-meter calibration for science-grade speed data. Designed to run on NVIDIA Jetson.
Telegram Bots
Bots and Mini Apps shipped on Telegram. Tap any to chat — they're all live.
Make a fully on-chain Starknet game playable by anyone, without a wallet or gas.
Memorabilia
@enter_memorabilia_musem_bot
Telegram Mini App entry point for the Memorabilia memory-card game on Starknet. Account Abstraction handles wallet creation behind the scenes; players match cards across 3 eras and 15 levels with gasless transactions and NFT minting via Cartridge.
Capture ideas, links, and notes the moment they hit — recall them later in plain language.
Second Brain
@danmwisecondbrainbot
Personal AI second-brain on Telegram. Forward links, drop voice notes, jot ideas; ask questions in natural language and the bot retrieves with context. Built around an LLM + vector store so semantic search beats keyword grep.
