Hi, I'm Bayyan

I'm a Web3 developer and open-source contributor focused on smart contracts, blockchain security, protocol testing, and AI-assisted software engineering.

My current work spans both EVM / Solidity and Solana, with a strong interest in identifying reliability and security issues, reproducing failures, writing regression tests, understanding root causes, and contributing practical fixes to open-source Web3 codebases.

🔗 Current Focus

• Smart contract development with Solidity & Hardhat
• Solana programs and protocol development with Rust
• Web3 security analysis and defensive engineering
• Transaction and authorization safety
• Oracle and protocol-state integrity
• Regression testing and failure reproduction
• TypeScript / JavaScript Web3 applications
• AI-assisted engineering workflows
• Open-source protocol contributions

🛠 Tech & Tools

Blockchain

Solidity · Hardhat · EVM · Solana · Rust · Web3

Development

TypeScript · JavaScript · Python · Node.js · Git · GitHub Actions

Testing & Security

Regression Testing · Security Analysis · Root Cause Analysis · Transaction Validation · CI/CD · Fail-Closed Design

AI-Assisted Engineering

I use AI-assisted development agents for code analysis, implementation support, testing, debugging, and technical documentation, while personally reviewing and validating the resulting changes.

🚀 Selected Work

Solidity / EVM

opn-testnet-hardhat-demo

A Solidity and Hardhat project for EVM smart contract development and testnet deployment workflows.

Solana Intent Guard

zeroclaw-solana-intent-guard

A deterministic, fail-closed Solana transaction policy gate designed to validate host-approved transaction intent while maintaining a read-only security boundary.

Percolator Ecosystem Contributions

I contribute testing, reliability improvements, bug fixes, and security-related changes across several Percolator Web3 repositories.

Areas of work include:

• Transaction authorization and signer boundaries
• Oracle integrity and price-source validation
• Account and protocol-state correctness
• PDA initialization and account validation
• Transaction confirmation handling
• Indexing reliability
• Regression testing
• CI and protocol hardening

Relevant repositories:

• percolator-prog
• percolator-nft
• percolator-oracle-keeper
• percolator-indexer
• percolator-launch

🎯 Interests

I'm interested in opportunities where I can continue developing my skills in:

• Solidity and smart contract engineering
• Web3 protocol development
• Blockchain security
• Smart contract testing
• Protocol infrastructure
• AI-assisted software engineering

I'm comfortable working in remote and asynchronous development environments, using GitHub-based collaboration, issue tracking, testing, documentation, and code review.
