Hi XDC Community!

Greetings, I'm Hamid, an ardent software engineer who has a deep fascination for blockchain technology and cryptocurrency. My interest in this captivating domain took root during my university years and it continues to direct my professional trajectory.

Over the previous 4 years, my role as a software engineer has primarily involved blockchain integration for two of the largest centralized exchanges in the MENA region. This position has enabled me to architect and produce secure and scalable "Enterprise Wallet Systems", a task that necessitated a comprehensive understanding and application of HD wallets, HSM, and MPC technology. Over time, I have gained familiarity with a range of blockchains and a profound knowledge of cryptography, which was essential for these projects.

💡 To augment my comprehension of blockchain protocols, I made the decision to investigate the source code of Bitcoin Core and Ethereum Node (geth). This practical approach has awarded me a profound comprehension of blockchain protocols and has sparked my interest to initiate research and study on:

  • Blockchain Scalability
  • Privacy
  • Ethereum layer 2 (validity proof/fraud proof rollups)
  • ZKP (zero-knowledge protocols)
  • MEV
  • Consensus Mechanism
  • Bridge and Blockchain Interoperability
  • Oracles

In the past few years, I've explored the domain of Decentralized Finance (DeFi). I've assisted companies in designing and executing various products in the web3 space, including:

  • NFT
  • Decentralized Exchange
  • Staking,
  • Account Abstraction
  • SmartWallet

🎯 Two of my most noteworthy contributions in this field include the introduction of EIP7503 ( and Private Proof of Solvency ( These achievements are a reflection of my dedication to propelling blockchain technology forward and creating a significant impact in the industry.
