# Basics XRBG tokens are a digital ownership certificate, where one token represents ownership of one fine gram of a 0.999 Good Delivery gold bar. The value of XRBG tokens track the real-time market price of gold, with each token's price based on the per-gram price of a 12.5kg LBMA-accredited gold bar. The XRBG token is an Ethereum-based token following the ERC-1400 protocol, making it compatible with all Ethereum and Polygon wallets that accept ERC-20 tokens. All transactions adhere to the rules of the smart contract on the Ethereum and Polygon blockchains. This smart contract eliminates human error, ensuring the XRB Gold ecosystem operates strictly as programmed. Like other Ethereum-based tokens, XRB Gold facilitates 24/7 settlement against various assets. Unlike traditional gold, which is only available for trade settlement during banking hours, XRBG tokens can be transferred anywhere, anytime. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
