A fractional, yield-bearing claim on verified Indonesian nickel production revenue, structured like a mining royalty. It is a real Stellar asset — not a synthetic, not a nickel price tracker, and not a claim on physical metal.

One production settlement period — roughly a month, following how official nickel data is published. Each epoch, verified production is recorded and TANUR is minted atomically, revenue is computed and funded in USDC, and holders claim their pro-rata share. Like real mining royalties, it settles in arrears, once the period’s data is final.

Each epoch pays tonnes produced × the official HPM reference price × the on-chain royalty rate (GORR), in USDC. On testnet the payout is funded from the project treasury — the amount is computed from audited public production data, and a signed royalty agreement is the mainnet step.

No — and that honesty is the point. Yield is computed from actual production and the official reference price each period, so if nickel prices fall or output drops, the payout shrinks with them. This is a claim on real commodity revenue, not a fixed-income product.

Prices come from an exchange feed (LME) and Indonesia’s government reference (HPM/ESDM); production comes from Antam’s audited, exchange-listed filings. Every epoch passes cross-validation, a deterministic plausibility gate, and an AI reasoning gate before it can reach the chain — and TANUR is minted atomically from the verified record.

Two autonomous agents on a public GitHub Actions schedule — no manual operation. An oracle agent validates official data and records each epoch monthly, when the source data is published; a settlement keeper computes royalties, funds each epoch, and sweeps expired claims every six hours. The only human step is KYC approval, and that is deliberate.

Gold tokens are asset-backed: one token equals metal sitting in a vault. TANUR is revenue-sharing: it pays a periodic USDC share of production revenue — closer to a royalty than to owning the commodity itself, so yield moves with production and price.

Three things break without it: the mint is cryptographically tied to verified data in a single transaction, so no one can insert a different number; holders prove their own yield entitlement with a Merkle proof instead of trusting an operator’s database; and USDC settles globally for cents, with a standardized anchor off-ramp to local currency.

Yes. Once your trustline is authorized, TANUR trades freely on Stellar’s built-in DEX. KYC gates holding and claiming — it is not a lock-up.

The market price lives on Stellar’s built-in DEX orderbook, so it can move with every trade. The treasury’s reference offer is repriced automatically every six hours by the keeper: average funded revenue over the last three epochs ÷ total supply × a 60-month payback. The anchor price tracks real production revenue — not an operator’s manual setting.

Just a Stellar wallet like Freighter. On testnet the app funds a fresh wallet, swaps to USDC, and a self-service demo KYC unlocks the full journey — buy TANUR, claim USDC yield, and withdraw to fiat via a SEP-24 anchor.

No. Tanur runs on Stellar Testnet as a hackathon MVP — nothing here is an offer of securities or investment advice. The contracts are open source with verified reproducible builds on StellarExpert, so you can audit exactly what they do.
