LRC-6909 Minimal Multi-Token

Abstract

LRC-6909 (mirrors ERC-6909) provides a gas-efficient minimal multi-token interface.

Specification

Simplified multi-token standard with reduced gas costs compared to LRC-1155.

Motivation

This standard ensures compatibility with the broader EVM ecosystem while enabling Lux-specific optimizations.

Rationale

Mirrors the corresponding Ethereum standard for maximum compatibility.

Backwards Compatibility

Fully compatible with existing ERC implementations.
