2026— Present
Junior Blockchain Developer
Block Stack
Implemented listener services to monitor and process on-chain events in real time. Built token swapping functionality integrating Uniswap on EVM and Raydium on Solana.
Portfolio / Résumé — 2026
Anirruth Santhosh
Blockchain developer & security researcher.
I build on-chain systems and break them before attackers do — shipping Solidity and Rust across EVM and Solana, and auditing DeFi protocols through Immunefi and Code4rena. Currently a Junior Blockchain Developer at Block Stack.
About
I'm a blockchain developer and security researcher with a B.Tech in Computer Science & Engineering (Blockchain Technology) from SRM University (2026). My work splits between building — smart contracts, cross-chain infrastructure, full-stack DeFi tooling — and breaking, through bug bounty programs and formal audits.
I compete in smart contract security contests and bug bounty programs across multiple platforms — see my full track record in Security research below — and completed the Cyfrin Updraft Smart Contract Security Program.
Experience
2025Aug — Nov
Blockchain Security Intern
SISA Infosec
Developed a framework for researching emerging trends in stablecoin integration within the payment industry. Conducted in-depth analysis of blockchain attack vectors to identify potential security risks.
—Ongoing
Blockchain Security Researcher
Independent
Specialized in identifying vulnerabilities in DeFi protocols through security contests and bug bounty programs. Participated in audits and peer review of blockchain applications, publishing findings on GitHub.
Security research
Code4rena
5 valid findings across contests including Arcade, Wildcat, and LoopFi, including a High-severity finding in Dopex.
Sherlock
Recurring top-50 finisher across contests including Cap, DODO, and Burve, with High-severity findings in Burve.
Codehawks
High and Medium-severity findings in the Core Contracts audit competition.
Cantina
Ranked #24 in the Symbiotic security contest with a Medium-severity finding.
Immunefi
Reported a High-severity vulnerability through the One Ring bug bounty program.
Selected projects
EasyHop — Solana
A hopper-style lending vault aggregator enabling one-click withdraw-to-deposit migration across Kamino Lend vaults. Full-stack monorepo: Express.js API with protocol adapters, React (Vite) frontend, and Jupiter Swap integration for cross-asset moves.
Cross-Chain Token Transfer
A cross-chain transfer solution using LayerZero's Omnichain Fungible Token standard to bridge tokens across EVM chains, with a mint-and-burn mechanism preserving a consistent global supply.
Decentralized Tender Management System
A secure, blockchain-based bidding system for tamper-proof tenders. Solidity smart contracts enforce transparency and prevent bid manipulation.
NFT Marketplace
A decentralized marketplace for minting, listing, buying, and selling NFTs, with on-chain listing management, ownership transfer, and payment flow.
X402 Payments Integration
An implementation around the x402 internet payment protocol handling payment-required HTTP flows, with request/response handling and payment payload verification for crypto-native pay-per-request APIs.
