About

I’m Sunil Kumar Chavhan — a Full-Stack & Blockchain Polymath who loves building systems that scale, ship fast, and break limits. I work across the entire stack: TypeScript, Next.js, Node.js, and cloud-native infrastructure, while also crafting secure on-chain solutions using Solana, Rust, and Solidity.

I have been a 5x Hackathon Winner and Top 4 Solana Hackathon Finalist, selected as one of only 72 fellows from 3,000 applicants, and part of the GitHub Campus Expert Summer 2025 cohort. I thrive at the intersection of Web2 × Web3—where real-time systems, microservices, and decentralized architectures meet.

Impact

Live market engine with on-chain settlement

Challenge

Sports prediction UX usually feels like betting, not real-time market trading.

Outcome

Designed a probability-driven trading flow where users can enter and exit positions live before event resolution.

Outcome is a live market platform for trading real-world sports outcomes with real-time pricing.

How Outcome works:

  • Each event has a live market where prices reflect the probability of each outcome
  • Users enter a position at the current price and can exit whenever the market moves in their favor
  • When the event resolves, winning outcomes are redeemed automatically on-chain

No traditional "bet wins" flow. This is a new way to trade what happens next.

Built on Solana with on-chain settlement and a non-custodial architecture.

For the best experience, open on PC or laptop. The current build is not optimized for mobile.

Impact

Goal-based SOL staking with automatic on-chain settlement

Challenge

Habit tracking alone does not create enough accountability when users can ignore the outcome without consequences.

Outcome

Built a commitment product where users lock SOL against real-world goals and smart contract rules return or reroute funds based on verified completion.

StakeUp is a Solana-based commitment product that lets users bet SOL on themselves.

Core concept:

  • A user sets a real-world goal, such as running 100 km in a week
  • The user locks SOL into an on-chain vault tied to that goal
  • The funds create financial accountability

How it works:

  • If the user completes the goal and it is verified, the staked SOL is returned
  • If the user fails, the stake is routed to a pre-selected charity or franchise wallet
  • Settlement happens through smart contract rules, not manual custody

Why it is different:

  • It is not just a habit tracker
  • It attaches real financial consequences to goal completion
  • It combines personal discipline, on-chain custody, transparent verification, and automatic fallback routing

On-chain concept:

  • Built with Anchor on Solana
  • Each goal creates a goal PDA, a vault PDA holding funds, and recipient / verifier state
  • The program enforces deadline-based verification, condition-based release, and one-time settlement

Trust model:

  • Users can submit manual progress
  • Verified progress can come from a backend verifier flow
  • The final outcome is controlled by explicit verifier logic, not unchecked user claims alone

Impact

End-to-end token lifecycle in one launchpad

Challenge

Launching a token often requires multiple fragmented tools and high setup overhead.

Outcome

Built one workflow for minting, liquidity operations, and swaps with modular React components for fast integration.

Sol Token Launch Pad is a platform built to simplify the creation, management, and launch of Solana-based tokens.

Core backend capabilities include:

  • Creating new tokens on Solana
  • Minting tokens
  • Managing liquidity pools (create, add, and swap)
  • Enforcing secure and efficient blockchain interactions

The project also includes modular React components for each feature to keep the UI integration fast and maintainable.

Impact

Real-time AML alerting bot for blockchain monitoring

Challenge

Compliance teams needed instant, actionable risk alerts across EVM and Solana activity.

Outcome

Implemented webhook-driven alerts with Telegram delivery and Prisma-backed tracking for faster compliance response.

Settll Telegram Bot is a TypeScript-based automation tool designed to interact with users via Telegram. It integrates with blockchain providers (EVM and Solana), leverages Prisma for database management, and features robust alerting, tracking, and webhook systems. The bot streamlines AML (Anti-Money Laundering) monitoring, provides real-time notifications, and supports seamless integration with external services, making it a valuable asset for financial compliance and blockchain analytics.
