# Thank-you wheel and bug bounty

Page: <https://scdoscan.io/bounty/>

## Thank-you wheel

* Free to play with any SCDO Shard0 EVM address. No purchase and no top-ups: there are no paid spins and the wheel balance cannot be paid into.
* Before each spin you pick **A Double** or **B Black hole** for your current wheel balance. A fair 50/50 draw on the server picks A or B: if it matches, your wheel balance doubles; if not, it resets to 0. The prize from that spin is added afterwards. Amounts already in withdrawal requests are never affected.
* Results are drawn on the server with a cryptographic random number generator before the wheel moves; the animation only shows that result. Every spin, pick, outcome and balance change is recorded with the address.
* Once an address has a wheel balance, you sign in with its wallet (a signature, not a transaction).

## Bug bounty

| Severity | Bounty     | Examples                                                                      |
| -------- | ---------- | ----------------------------------------------------------------------------- |
| Low      | 50 SCDO    | Display or text errors and minor issues that do not put funds or data at risk |
| Medium   | 200 SCDO   | Wrong data, broken features, or issues that affect many users                 |
| High     | 1,000 SCDO | Issues that could put funds, private keys or account security at risk         |

The SCDO team sets the severity based on impact; bounties are fixed, not random.

**How to report:** send a short description, steps to reproduce, the page or contract address involved, and your SCDO Shard0 EVM address to <https://t.me/SCDOLabor>. Do not exploit or publish the issue before it is fixed. Accepted reports get a bug ID and severity; the bounty is paid after the fix is released.
