# Bridge

### Mint and burn

The Bridge burns jFIATs on the origination chain and mints the same amount of jFIATs on the destination chain, at a 1-to-1 ratio.

The fees are paid in the gas token of the origination chain.

{% hint style="info" %}
The Bridge uses the Cross-Chain messaging protocol of Chainlink (CCIP) to transfer the information from one chain to another one. When jFIATs are transferred between chains, the amount of jFIATs to be minted on the destination chain is sent through a message using Chainlink's CCIP. Once the message is received, the Bridge mints the jFIATs and send them to the recipient.

{% endhint %}

### Limits

The governance can set limits per jFIATs and per chain.
