Requirements

A wallet

Any browser wallet that speaks EIP-1193 works. The dashboard discovers installed wallets through EIP-6963 and lists each provider under the name it reports, rather than guessing from injected flags. That matters because more than one extension advertises itself as the same wallet, and picking the wrong one is the most common way people end up signing from an address they did not expect.

Hardware wallets work through whichever browser wallet you already use to drive them. The only operations Sitowise asks for are a message signature to sign in, a plain ETH transfer to buy a node, and a contract call to withdraw. No token approval is ever requested.

The network

Sitowise is deployed on Robinhood Chain and nowhere else. There is no testnet deployment and no address on any other chain. If someone shows you an Sitowise contract on a different network, it is not this project.

The dashboard offers to add the network for you. If you would rather add it by hand, these are the exact parameters it sends.

{
  "method": "wallet_addEthereumChain",
  "params": [
    {
      "chainId": "0x1237",
      "chainName": "Robinhood Chain",
      "nativeCurrency": {
        "name": "Ether",
        "symbol": "ETH",
        "decimals": 18
      },
      "rpcUrls": [
        "https://rpc.mainnet.chain.robinhood.com"
      ],
      "blockExplorerUrls": [
        "https://robinhoodchain.blockscout.com"
      ]
    }
  ]
}

How much ETH

A node costs exactly 0.02 ETH, sent as a plain transfer to the payments wallet. The amount is checked off chain by the watcher rather than by the contract, and it has to match: a transfer for any other amount is held for manual review instead of minting a node.

You pay the gas for that transfer, and later the gas for your own withdrawals. You do not pay the gas to mint. Minting is mintFor, and only the relayer can call it, so the operator pays for it.

Those figures were measured against this contract, and the cost in ETH depends on the gas price at the time. Budget the node price plus a little for the transfer, and keep a small amount back afterwards so a withdrawal is never blocked by an empty gas tank, which is the situation described in Troubleshooting.

Limits that apply to you

• 25 nodes per wallet, enforced in the contract. See Limits.
• Minting can be paused by the operator. Withdrawals cannot be paused; that asymmetry is deliberate and is described on Security model.
• Public API endpoints are rate limited per IP. See the API overview.
