TOPIC 02

Availability

Pilot status, chains, minting and redemption.

Is USDXX live?

No. USDXX is in a controlled pilot on testnet. There is no mainnet issuance, live minting or redemption, or acceptance of customer funds. Public launch depends on partner readiness, legal clearance, security testing and successful redemption testing.

What is the Trust Envelope?

The Trust Envelope is a proposed proof layer: a payment can carry encrypted proof of eligibility, purpose and agreed conditions, and can settle only when those conditions are met. These features are in design and subject to legal review before launch.

Is my transaction data public?

Public blockchains can expose transaction details. USDXX is designed to limit public proof to system information such as total supply, mint and burn activity, reserve coverage and attestations. Identity, amount, balance and wallet-relationship privacy features are still part of the proposed design and are not a guarantee of anonymity.

Fees and limits

What is and is not established yet.

Are there fees to transfer USDXX?

On-chain wallet-to-wallet transfers require the network’s gas fee. Fees for direct minting or redemption have not been finalized and depend on the issuer’s terms.

Does holding USDXX pay interest?

No. Holding USDXX on its own pays no interest. USDXX Earn is a separate proposed program with its own terms, eligibility and risk disclosures; it is not live.
