## SBT Verification Principles

TBook supports a variety of on-chain and off-chain tasks as SBT Verification criteria. Please review the following before setup:

<details>

<summary><strong>Telegram Group / Channel Tasks</strong></summary>

If you want to verify whether a user has joined a Telegram group or subscribed to a channel, please ensure the group/channel is Public.

> Due to Telegram limitations, TBook can only support automatic verification for Public groups/channels.
>
> For Private group/channel verification, this is a **Pro feature** and requires you to provide a **Verification API** and pay an additional fee.

</details>

<details>

<summary><strong>On-chain Credential Verification (Pro)</strong></summary>

To verify on-chain activities (e.g., contract interaction, asset staking, NFT claiming), custom logic will be developed by the TBook team.

> After deploying your SBT and launching the SBT Verification, our team will contact you during the review process. You’ll need to provide clear task definitions and pay for a fee to cover development costs (Pro feature).

</details>

<details>

<summary><strong>Custom Off-chain Credential Verification (Pro)</strong></summary>

If you require off-chain tasks such as in-game level contributions or topping a leaderboard in your app, you need provide the Verification API **following our format.**

> This integration also falls under Pro services and requires an development fee.

</details>

Reminder

* For simpler use cases, we recommend starting with TBook’s **native verification types** (e.g., wallet binding, joining a public Telegram group). These are quick to set up and free to use.
* For any **Pro verification tasks**, please contact the TBook team in advance to discuss feasibility. We’re here to support your efficient implementation.
