A record of learning blockchain technology: building a foundation in the language, then taking questions into wallet integration, backend engineering and product security.
Currently learning TypeScript. Building the foundations step by step, with exercises and observations to follow here.
A route to work through gradually. I am at the first stage; later directions will evolve through practice.
Types, asynchronous flows and modules, followed by typed event handling.
RPC interaction, log decoding and ERC-20 event normalization.
Contract foundations and a replay-protected event registry.
Unit, fuzz and invariant testing.
Testnet deployments, transaction hashes and verification reports.
The wallet platform is a direction for future practice, currently a record of scope and architecture plans.
A planned educational platform for documenting wallet API, transaction lifecycle, backend consistency, and product-security decisions on testnets.
Read the project planRecord the questions first, then reproduce and test them against an actual implementation.
A theoretical security analysis of the gap between authentic webhook delivery and unique business processing.
Read the research noteWEB3 LAB is an independent space for learning and engineering notes. The current focus is TypeScript, with a longer-term interest in wallet integration, backend engineering, product security and solution design. Learning, planned projects and verified outcomes are labeled separately.
Projects are educational, testnet-oriented, unaudited and do not handle real funds.
