# Cross-Chain Bridge

## Instruction

Themis will be deployed on Ethereum but also uses a third-party cross-chain bridge. Using the cross-chain bridge service allows you to use TMS tokens outside of Ethereum.

Before using cross-link bridges, you need to be aware of the following risks:

* ERC20 assets will be held by a third party once they enter the cross-chain bridge. If the third-party generates a loss resulting in the assets not being able to cross back to Ethereum, you may be compensated by the third party, but the TMS on Ethereum may not be recoverable.
* Before using the cross-chain bridge, try to make a small transfer. Test and confirm if the contract address of the assets is the officially published contract address.
