Hi, I'm Cheng Qian (钱诚) 👋

Blockchain & AI Architect · 17 years building at the protocol layer

📜 Ethereum Standards Author

I'm the sole author of 3 finalized Ethereum ERC standards:

Standard Title Summary
ERC-7743 Multi-Owner Non-Fungible Tokens (MO-NFT) Shared ownership of one NFT across multiple owners, with provider-defined transfer fees
ERC-7837 Diffusive Tokens A fungible token that mints on transfer, with a per-token native fee and a capped supply
ERC-8063 Groups — Membership Tokens ERC-20 tokens where balance is membership level, with threshold-based access control

🚀 Current Projects

Deakee — Web3 DApp

The first production application built on ERC-8063: coupon access is gated by DKG token balance, so a member's balance is their membership tier. 1,600+ brand partners including Alibaba, Chow Sang Sang and Kitco. Live on iOS, Android and the web.

Reference implementation: erc-8063-reference — the membership-token contracts, deployed on Arbitrum One.
