Owning STAU: Gold Use, Storage and Risks

STAU is a Polygon-issued token associated with a project that aims to let customers buy physical gold products through a blockchain-based distribution system. The project identifies Starry Japan as a gold-product manufacturer and FedEx as a shipping partner. That describes the intended product and delivery model; it does not, by itself, explain what rights you receive by holding STAU.

The project has not specified whether STAU is required to purchase gold, whether it can be redeemed for gold, or whether a token represents ownership of or a claim on any metal. Do not assume that holding STAU gives you gold or a right to delivery. Before treating it as a route to buying gold, check the project’s current terms for accepted payment methods, product availability, shipping costs, returns, and who is responsible if an order is delayed or lost. Token ownership and ownership of a delivered gold product are separate matters unless the project’s terms clearly connect them.

STAU is issued on Polygon, so you need a wallet that supports Polygon and the token’s contract standard. A Polygon-compatible wallet can hold tokens on that network, but wallet support does not confirm that a token is genuine or that it can be traded or used to buy a product.

Before receiving or sending STAU, confirm the official Polygon contract address through the project’s own channels. Check that the wallet is set to Polygon, and send a small test amount first if you are unsure. A token with the same name or symbol can exist at a different contract address; selecting the wrong one may leave you holding an unrelated token. Polygon transfers also require the network’s transaction fee, generally paid in its native gas token. STAU is not listed as native to Polygon or any other chain in the project description, so do not assume a bridge or a version on another network is official.

STAU has a maximum and total supply of 10 billion tokens. About 350 million were reported as circulating on October 2, 2026—roughly 3.5% of the total. The remaining supply could affect the amount of STAU in circulation over time, but the project’s release schedule and any lockups are not specified. Check for current token-distribution and vesting details before relying on a supply estimate.

As a snapshot, STAU traded at about $0.0073 on October 2, 2026, with a reported market capitalization of about $2.6 million and fully diluted valuation of about $72.9 million. Reported 24-hour volume was unavailable. These are changing market figures, not a valuation of the gold products or a promise that you can sell at a particular price. A thin or unavailable trading-volume figure can make it harder to judge how easily you could exit a position. No price direction can be inferred from a single snapshot.

Store STAU in a Polygon-compatible wallet you control if you want self-custody. Keep your recovery phrase offline, never share it, and beware of anyone asking you to enter it to claim tokens or arrange a gold purchase. A hardware wallet can keep signing keys offline, but you still need to verify the network, contract address, and transaction details on the device before approving a transfer.

The main risks go beyond wallet security. The token’s role in gold purchases and any redemption or ownership rights are not specified by the project. Physical orders may also involve shipping, delivery, returns, and customer-service issues that a blockchain transfer cannot resolve. STAU’s value may change sharply, and a token balance may be difficult to sell if trading activity is limited. Losing your keys, signing a malicious approval, or sending tokens to the wrong address can lead to irreversible loss. Hold only what you can afford to lose, and verify the project’s terms before connecting a wallet or paying for a product.
