Become a sponsor to Weiliang Li

I maintain open-source cryptography and blockchain infrastructure libraries that are used by developers worldwide. Your sponsorship helps me dedicate more time to maintaining these projects, improving security, and building new tools for the community.

My Projects

ECIES - Elliptic Curve Integrated Encryption Scheme

A suite of cryptography libraries implementing ECIES for secure data encryption across multiple platforms:

  • ecies/py - Python implementation with support for secp256k1 and curve25519
  • ecies/js - JavaScript/TypeScript implementation
  • ecies/rs - Rust implementation for maximum performance

These libraries provide battle-tested encryption that's used in blockchain applications, secure messaging, and privacy-focused tools.

Blockchain & Web3 Tools

  • python-bip44 - Simple Python implementation of BIP44 for hierarchical deterministic wallets. Essential for cryptocurrency wallet development.
  • web3-input-decoder - Offline transaction input decoder for Ethereum smart contracts. Decode function calls and constructor parameters without needing a provider.

Web Development

  • fastapi-django - Integration example showing how to use FastAPI with Django ORM, combining the best of both frameworks.

Why Sponsor?

Open-source maintenance takes significant time and effort:

  • Security audits - Reviewing code, fixing vulnerabilities, and keeping dependencies updated
  • Documentation - Writing clear guides and examples for developers
  • Support - Responding to issues, reviewing PRs, and helping users
  • New features - Building improvements requested by the community
  • Compatibility - Ensuring libraries work across different platforms and versions

Your sponsorship allows me to dedicate more focused time to these projects instead of just evenings and weekends.

Thanks for your support!
