# How to contact service providers for cross-chain issues?

Transit Swap’s cross-chain functionality is currently integrated with Changelly, HifiSwap, ButterSwap, and METAPATH.

In the cross-chain transaction records, you can identify which service provider was used via the logo in the top-right corner of the transaction details. Please contact the corresponding official support channel for feedback, ensuring faster and more efficient issue resolution.

⚠️ Note: On Telegram, any account that initiates a private message to you is a scam. Please report and block such accounts immediately.
