# Example Apps

### Single query

Refers to one-to-one queries. For example, ENS on Ethereum can be used to authenticate other Layer2s or issue new NFTs or Fungible Tokens in a more secure way.

### Multiple queries

Refers to one-to-many queries. For example, there is a cross-chain yield aggregator that queries the APY of each lending protocol for each chain, compares them, and rebalances them to the most optimal lending protocol.

**Omni-chain lending**: Deposit, withdraw, lend and borrow across any chains.

**Cross chain governance:** cross-chain voting system that allows voting from multiple chains and aggregating the voting data.
