ERC-8063 Reference Implementation on Arbitrum One

First production reference implementation of ERC-8063 (Groups — Membership Tokens) deployed on Arbitrum One.

---

What is ERC-8063?

ERC-8063 is a finalized Ethereum standard titled Groups — Membership Tokens, authored by Cheng Qian (@jamesavechives).

A Group is an ERC-20 token extended with threshold-based membership semantics:

function isMember(address account, uint256 threshold) external view returns (bool);

Token balance ≥ threshold → membership is granted. This enables token-gated access, tiered rewards, and on-chain loyalty systems without off-chain oracles.
