Real shares and Proof

A unit on the NYXERON contract is a claim on real stock tokens. One unit is 0.001 of a share. The tokens themselves are Robinhood stock tokens on Robinhood Chain (chain id 4663). They are held by the game's warehouse.

The warehouseCopy Anchor Link

The warehouse is an address on Robinhood Chain with no private key. A NEAR account controls it through Chain Signatures: NEAR's MPC network signs the warehouse's transactions when that NEAR account asks. Nobody holds a key that could move the shares outside the game.

When a party ends, the warehouse buys what the party owes:

1. The party's wholesale goes to the treasury, which keeps the warehouse topped up with USDG (and a little ETH for gas) through NEAR Intents.
2. The warehouse swaps USDG for the stock token through KyberSwap. It checks that the route sends exactly the pinned token to the warehouse itself, takes no fee, and returns at least 98% of the market value.
3. The swap's receipt must show the stock token arriving at the warehouse, at least what the party owes. Only then does the contract mint the units, with the swap's transaction hash as the proof. Each proof backs one mint only.

The warehouse works with safety limits. A swap is at most $50 and a day at most $500. If a swap ever comes back short, the warehouse sends no new swap for any party until a person has checked it.

Testnet: synthetic stocks on Robinhood Chain testnetCopy Anchor Link

Robinhood's stock tokens exist on mainnet only, so on testnet the warehouse buys synthetic stand-ins (sTSLA, sCRCL, …, 18 decimals with balanceOfUI like the real ones) for test dollars (tUSDG) from a small market on Robinhood Chain testnet (chain 46630). Everything else is the same code as mainnet: the warehouse is a Robinhood Chain address controlled by the NEAR account nyx-warehouse.testnet through Chain Signatures, the api checks the swap call, the exact approve, the minimum out and the token's Transfer to the warehouse, and the swap's hash is the mint's proof on NEAR.

A real example, party dfec4462-20 (2 × CRCL): the warehouse bought 0.002 sCRCL in this swap, then the contract minted the units with that hash as proof and settled them to the guest. Proof labels these holdings "synthetic (testnet)".

NEAR Intents has no testnet, so Add money and Cash out show real 1Click quotes as dry runs.

Check it on ProofCopy Anchor Link

app.nyxeron.xyz/proof needs no account. It shows:

• On NEAR: the game contract, the USDC contract and the key the contract accepts quotes from.
• Backing: for each stock, the units in circulation and the shares they stand for. On mainnet it also shows the shares the warehouse holds, and whether they cover the units.
• Party by party: each recent party's release, mints (with their proof) and settle batches, each with a link to its transaction.

The same data is public as JSON: see the API reference.

Known risksCopy Anchor Link

Robinhood's token issuer can block, pause or burn its tokens, and the Robinhood Chain sequencer can filter transactions. Purchases are kept small, and the contract can be paused: paused, it refunds new payments and stops release, mint and settle, while holders can still move their units and hosts can still claim their margin.
