Sithu Nyein

Web3 & AI EngineerYangon, Myanmar

I build software people can run for real: on-chain credit flows, confidential on-chain games, and agent accountability rails. Currently anchoring the DevConnect developer ecosystem, managing the platform's core hubs for student developers and Web3 builders. I ship on Superteam, DoraHacks, and HackQuest. Open to remote and full-time engineering roles.

Selected work

Products I shipped

03

Live products across DeFi credit, confidential on-chain gaming, agent accountability, and callable AI services.

01

Spark

Pay once. Unlock credit. Verified payment credit on Creditcoin.

DeFi · Creditcoin

Other credit apps cannot trust a payment that happened somewhere else without paperwork or a middleman. Spark verifies the payment with Attestcoin, then opens credit on Creditcoin. I built the Next.js app, Foundry contracts, and verifier path across Sepolia and Creditcoin testnet.

pi River

Confidential heads-up Hold'em where the house cannot see your cards.

Honorable Mention · Inco × Megapot

Most online poker rooms see every hole card. pi River deals them Inco-encrypted onchain: the deck is shuffled as ciphertext, hands are compared without revealing losers, and cards only open at showdown. Google sign-in and a silent play wallet mean zero MetaMask. Honorable mention in the Inco × Megapot Summer Game Jam.

Equxi

Trust layer for AI agents on Solana — bond, enforce, slash, compensate.

Agents · Solana

Nobody can safely hand an autonomous agent real money today. Equxi makes agents register, lock SOL as bond, accept enforced constraints like spend limits and allowlists, and get slashed on-chain when they misbehave — with automatic compensation to victims. Superteam Agentic Engineering grant; program live on devnet.

Notes

What I am exploring

All writing

Public drafts on systems that settle on-chain and tooling that makes Solana failures easier to read. Not peer-reviewed papers.

DeFi

Payment-verified credit without paperwork

Spark uses Attestcoin to prove a Sepolia payment, then unlocks credit on Creditcoin.

Recognition

Poker where the dealer is math, not a room

pi River deals Inco-encrypted hole cards and computes winners on ciphertext — an Inco × Megapot Summer Game Jam honorable mention.

Agents

Bonds and slashes for autonomous agents

Equxi locks SOL behind agent behavior rules on Solana — enforce, slash, compensate.

DevConnect

DevConnect developer ecosystem

Anchoring the DevConnect developer ecosystem, managing core hubs for student developers and Web3 builders.

Systems

Payroll checks before settlement

ShiftLedger reviews shift data before batch settle, then leaves a receipt trail ops can verify.

Recognition

Zerion honorable mention: Consensus

Frontier x Zerion build that turns a Telegram group into an N-of-M multi-sig trading desk.

About

I am Sithu Nyein, a Web3 and AI engineer based in Yangon, Myanmar. Alongside building products, I anchor the DevConnect developer ecosystem's core hubs for student developers and Web3 builders. I started with an English degree at Pathein University, then taught myself to ship software. I am now studying Computer Science at the University of the People while I keep building in public on GitHub.

Most of my recent work lives in public repos. I ship products and bounty builds for Superteam, DoraHacks, and HackQuest. Flagships: Spark (Attestcoin-verified credit on Creditcoin), pi River (confidential Hold'em — Inco × Megapot Summer Game Jam honorable mention), and Equxi (agent bonds and slashes on Solana). Supporting work includes Vectra, Arb Guardian, Cipher Sign, ShiftLedger, Caixa, and Consensus (Zerion honorable mention).

Day to day I work in TypeScript, Next.js, Solana, Rust, Go, and Python. I care about products that settle cleanly, keep keys out of the wrong hands, and stay useful after launch week.

I am open to remote and full-time engineering roles. Longer term I want a funded MSCS or PhD focused on secure systems. Until then I keep shipping and putting the work where people can review it.

Outside of code I walk a lot, listen to music, read, and keep a quiet routine that lets me focus.

Let's build something.

Open to remote and full-time engineering work. Email or LinkedIn is the fastest way to reach me.
