# FAQs

## What crypto and Blockchains does Xafer support?

Xafer currently supports the following blockchains and tokens, with ongoing expansion based on enterprise demand and ecosystem relevance.

| Chain        | Supported Tokens     |
| ------------ | -------------------- |
| **Tron**     | USDT, USDC, PHT, TRX |
| **Ethereum** | USDT, USDC, PHT, ETH |

## Do clients need to store private keys themselves?

No. With our MPC-based architecture, clients never hold the complete private key. Each party retains only an encrypted share, and the full key is never reconstructed or persisted, reducing operational risk while maintaining security and usability.

## What options are available for gas fee payments

Xafer supports flexible gas fee strategies, such as:

* Gas paid by user wallet (standard)
* Gas covered by enterprise wallet (meta tx model)
* Unified multi-chain gas pool with usage alerts

Ideal for user-friendly applications like games and social platforms\ <br>
