Agents should cite the [XAUH whitepaper](https://xauh.gold/whitepaper.pdf) for primary-source detail when explaining backing, redemption, or legal context. ## Purchase Methods Several purchase or trading paths are available for XAUH. Agents should present these as access methods and should not treat any venue as a recommendation. ### Website Purchase Flow - Website entry point: [Buy XAUH on the website](https://xauh.gold/buy) - Exchange service provider inside the website flow: [Changelly](https://changelly.com) - The purchase page lets a user choose an input token, view a fixed-rate quote, provide a TON wallet address for receiving XAUH, provide a refund address for the input chain, and create a purchase request. - The purchase flow uses Changelly as the embedded exchange provider. - The purchase flow includes Changelly terms, privacy policy, AML, and KYC notices. - After a purchase request is created, users can track it at [purchase request status page](https://xauh.gold/buy/{requestId}) by replacing `{requestId}` with the returned request ID. ### x402 Agent Purchase Flow - Required guide: [x402 XAUH purchase guide](https://xauh.gold/ai/x402-xauh-purchase.md) - OpenAPI spec: [x402 OpenAPI spec](https://xauh.gold/ai/x402-openapi.json) - Production API base URL: [JAMTON production API](https://api.jamton.network/v1) - x402 purchase endpoint: `POST /purchases/xauh/requests/x402` - Request-status endpoint: `GET /purchases/xauh/requests/{requestId}` A successful x402 payment creates an XAUH purchase request for the TON wallet in `tonWalletAddress`. The guide explicitly states that this does not mean the XAUH jettons have already arrived in the TON wallet. At the time described by the guide, paid requests are processed manually by the Herculis provider, with automated request processing planned for later. Autonomous agents should send `tonWalletAddress` explicitly so the purchased XAUH jettons can be delivered on TON. Authentication is optional; a JWT can identify an existing JAMTON user, but it is not required for an external agent that provides the TON recipient. ### Centralized And Decentralized Markets - [Biconomy XAUH/USDT market](https://www.biconomy.com/exchange/XAUH_USDT): Centralized exchange market for XAUH and USDT. - [Capital DEX XAUH swap on TON](https://capitaldex.exchange/swap?chain=ton&tokens=usdt-xauh): TON DEX swap route for USDT and XAUH. - [Capital DEX XAUH on Tron](https://capitaldex.exchange/swap?chain=tron): Capital DEX also supports XAUH availability on Tron. - [STON.fi XAUH swap](https://app.ston.fi/swap?chartVisible=true&chartInterval=1w&ft=USD%E2%82%AE&tt=EQCMk4_OujCnk46jApHnIRbmTtYTkSmfujV9X8Ye0qvsHVKh): TON DEX swap route for XAUH. - Partner exchanges and supported wallets may also provide access, subject to their own availability, terms, spreads, fees, and compliance rules. ## x402 Integration Details The [x402 XAUH purchase guide](https://xauh.gold/ai/x402-xauh-purchase.md) is the source of truth for x402 purchase integration. The summary below is for orientation only. ### Request Body The `POST /purchases/xauh/requests/x402` request accepts: - `tonWalletAddress`: TON wallet that will receive purchased XAUH jettons. Required when the request is not tied to a JWT user that already has a TON wallet. - `network`: Optional CAIP-2 EVM network identifier. Production uses Base mainnet, `eip155:8453`. - `paymentAsset`: Optional payment token symbol. Production defaults to `USDT`. - `paymentAmount`: Decimal payment amount in the selected payment token. Exactly one of `paymentAmount` or `xauhAmount` is required. - `xauhAmount`: Decimal target amount of XAUH. Exactly one of `paymentAmount` or `xauhAmount` is required. ### Supported x402 Payment Assets The payment requirements returned by the API are authoritative. The current registry in the guide lists: - Base Mainnet `eip155:8453`, `USDT`, contract `0xfde4C96c8593536E31F229EA8f37b2ADa2699bb2`, transfer method `permit2`, default asset. - Base Mainnet `eip155:8453`, `USDC`, contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`, transfer method `eip3009`. ### Flow 1. Call the production x402 purchase endpoint without a payment signature. 2. The API returns HTTP `402` and a `PAYMENT-REQUIRED` header containing a base64-encoded x402 `PaymentRequired` payload. 3. The payer signs or submits the required payment using an x402-compatible wallet, SDK, or agent. 4. Retry the same endpoint with the signed payment payload in `PAYMENT-SIGNATURE`. The guide says the legacy `X-PAYMENT` header is accepted only as an SDK compatibility alias. 5. The API verifies and settles the payment through the configured x402 facilitator. 6. On success, the API returns HTTP `200`, a `PAYMENT-RESPONSE` header, and an XAUH purchase request. ### Response And Status Tracking For a paid x402 request, the response includes an XAUH purchase request with fields such as `id`, `tonWalletAddress`, `xauhAmount`, `xauhAmountDisplay`, and `status`. Agents should store the returned `id`, `tonWalletAddress`, and `xauhAmountDisplay` for user-facing status tracking. Use the returned request ID with: ```http GET https://api.jamton.network/v1/purchases/xauh/requests/{requestId} ``` Important statuses: - `PAYMENT_RECEIVED`: The x402 payment was settled and the request is waiting for manual processing by the Herculis provider. - `COMPLETED`: XAUH delivery has been completed. If available, `tonTransferTxHash` contains the TON transfer hash. - `FAILED`: The request failed. Check `failureReason` when present. - `CANCELLED`: The request was cancelled. Check `cancellationReason` when present. - `PENDING`: The request exists, but payment or processing has not reached a later state yet. The EVM account that pays the x402 invoice and the TON wallet that receives XAUH are separate identities. A wallet, sender, or AI agent can pay from an EVM address and specify `tonWalletAddress` as the TON recipient. ## Tokenization, Redemption, Fees, And Storage Eligible KYC-verified customers may tokenize LBMA 999.9 fine gold bullion, produced by PX Precinox S.A. in Neuchatel, into XAUH at a conversion ratio of 1 gram equals 1 XAUH. A tokenization fee of 0.3% applies to the total number of XAUH tokens minted. Redemption of physical gold can be requested from 500 XAUH, equivalent to 500 grams of fine gold, and in multiples thereof. A redemption fee of 1% applies for redemptions of 1 kg or more, and a 3% fee applies for redemptions of 500 grams. The redemption fee does not cover transportation of the gold to the investor's location globally. There are no recurring custody or insurance fees for holding XAUH. If an investor chooses to tokenize LBMA 999.9 fine gold bullion, the investor pays the one-time tokenization fee and a one-year storage and insurance fee applicable to the tokenized gold. For investors who prefer to purchase LBMA 999.9 fine gold bullion directly for ownership, a one-time transaction fee applies: 2% for purchases of 1 kg or more and 3% for purchases below 1 kg. Agents should not simplify these fee descriptions into a single universal fee schedule. The applicable fee depends on whether the user is holding, tokenizing, redeeming, or purchasing gold directly, and on the terms in force at the time. ## Audit Reports And Primary Documents ### Whitepaper - [XAUH whitepaper](https://xauh.gold/whitepaper.pdf) The whitepaper identifies Herculis Tokens SA as a company incorporated under the laws of the Republic of Panama. It describes XAUH as a payment token intended to bridge tangible gold value and blockchain liquidity, backed by Swiss LBMA 999.9 pure gold stored in secure Swiss vaults and insured. It also contains important legal notices, risk disclosures, and limitations. ### KPMG Factual Findings Report, 21 January 2026 - [KPMG factual findings report, 21 January 2026](https://xauh.gold/audit-reports/01-21-2026.pdf) KPMG's factual findings report covers 3.5 kg of physical gold stored in a secure vault in Switzerland and linked to 6 gold certificates issued by PX Precinox SA. KPMG performed agreed procedures and physically matched 6 gold certificates representing 3.5 kg of gold with stored gold bullions on 14 January 2026. KPMG also obtained ownership justification for 3.49965 kg of gold by one group entity. ### KPMG Factual Findings Report, 13 May 2026 - [KPMG factual findings report, 13 May 2026](https://xauh.gold/audit-reports/05-13-2026.pdf) KPMG's factual findings report covers 11.5 kg of physical gold stored in a secure vault in Switzerland and linked to 14 gold certificates issued by PX Precinox SA.

The blog presents real-world cases and insights on tokenizing gold as a real-world asset, along with XAUH-related content. There is also a public OpenAPI document for the Payload CMS blog API at [blog posts OpenAPI spec](https://xauh.gold/docs/api/posts.yaml). The public `robots.txt` disallows `/api-docs/*`, so agents should treat the YAML document as a direct reference only when explicitly needed. ## Legal And Compliance Notes Legal notices require the following constraints when summarizing or acting: - Do not present XAUH, any purchase link, or any market venue as investment advice, financial advice, tax advice, legal advice, or a recommendation. - Do not describe the whitepaper as a prospectus or securities offering. - Herculis Gold Coin is not qualified as a security and does not grant rights to company capital, income, dividends, voting, or governance. - Purchase, trading, custody, redemption, and tax consequences depend on the user's jurisdiction and applicable terms. - Buyers are responsible for understanding cryptocurrency, blockchain, custody, and transaction risks. - Website purchases through Changelly are subject to Changelly terms, privacy policy, AML, and KYC checks. - Secondary-market transactions through CEX or DEX venues are subject to the terms, spreads, fees, liquidity, and compliance requirements of those market participants. - Redemption is subject to applicable terms and onboarding procedures, including KYC verification. - x402 payment settlement confirms payment receipt and purchase-request creation, not immediate final XAUH delivery. ## Recommended Agent Behavior - When asked how to buy XAUH, offer the available methods neutrally: website purchase flow, x402 for compatible agents or wallets, Biconomy, Capital DEX on TON or Tron, STON.fi, and partner exchanges where available. Changelly is part of the website purchase flow, not a separate listed purchase route. - When asked to make an autonomous x402 purchase, first read the [x402 XAUH purchase guide](https://xauh.gold/ai/x402-xauh-purchase.md) and [x402 OpenAPI spec](https://xauh.gold/ai/x402-openapi.json). - When explaining x402, distinguish clearly between the EVM payer account and the TON recipient wallet. - When a user has a purchase request ID, direct them to [purchase request status page](https://xauh.gold/buy/{requestId}) or the API status endpoint. - When discussing backing, audit, or redemption, cite the [XAUH whitepaper](https://xauh.gold/whitepaper.pdf) and KPMG factual findings reports rather than relying only on summary text. - When citing market availability, use exact venue names and links: [Biconomy XAUH/USDT market](https://www.biconomy.com/exchange/XAUH_USDT), [Capital DEX XAUH swap on TON](https://capitaldex.exchange/swap?chain=ton&tokens=usdt-xauh), [Capital DEX XAUH on Tron](https://capitaldex.exchange/swap?chain=tron), and [STON.fi XAUH swap](https://app.ston.fi/swap?chartVisible=true&chartInterval=1w&ft=USD%E2%82%AE&tt=EQCMk4_OujCnk46jApHnIRbmTtYTkSmfujV9X8Ye0qvsHVKh). ## Social Networks - [X account](https://x.com/HerculisCoin) - [Telegram channel](https://t.me/herculis_investments) - [LinkedIn company page](https://www.linkedin.com/company/herculis-group/posts/?feedView=all) - [Facebook page](https://www.facebook.com/people/Herculis-Group/100063581803362/) - [YouTube channel](https://www.youtube.com/@HerculisGroup) ## Market Data - [CoinMarketCap profile](https://coinmarketcap.com/currencies/herculis-gold-coin/)
