# Relaying Request

### **Relayer**

Asset transfer across chains is based on the consensus among the local nodes which serve as the validators on Glitter Bridge. Protocol A and protocol B of both primary and secondary chain must arrive at a consensus from each side of the chain smart contract and oracle request to successfully approve the mint and burn request across two chains that assets have been transferred. The Glitter Bridge smart contract allows these two chains to communicate request and approval messages from each respective node via a Relayer.
