# 📊 Token Allocation & Vesting

#### Token Details

| Item                   | Value                 |
| ---------------------- | --------------------- |
| **Name**               | Black                 |
| **Symbol**             | BLK                   |
| **Standard**           | ERC-20                |
| **Network**            | Base Mainnet          |
| **Max Supply**         | 1,000,000,000 BLK     |
| **Deflationary Floor** | 210,000,000 BLK       |
| **Transfer Burn Rate** | 2% (owner adjustable) |

***

#### 🔥 Deflationary Model

BlackChain is implementing a **long-term deflationary model** to reduce the circulating supply from **1B → 210M tokens**, mirroring Bitcoin’s scarcity.

Deflation is driven by token burns from:

* Transaction fees
* Premium content purchases
* Learn2Earn reward redemptions
* Staking activity and platform access

2. View USDC balance → purchase BLK
3. Verify purchase via [BaseScan](https://basescan.org/address/0xB6B6135C7Db6bF600AB5E05219d7B0e8527E189b)
4. During presale → tokens won’t auto-appear in MetaMask
   * To view:
     * Go to the presale contract on BaseScan
     * Click “Read as Proxy”
     * Enter wallet address in the **investors** field
     * Balance displays with 18 decimals (e.g., `2000000000000000000 = 2 BLK`)
5. After presale ends → tokens can be claimed through the **Claim Button** (not live until presale closes).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.blackchain.io/presale-and-token/token-allocation-and-vesting.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
