# Interoperability and Bridging

> Explore Hedera's interoperability and bridging options: cross-chain messaging protocols like Chainlink CCIP and LayerZero, and ready-to-use bridged assets like USDT0.

Interoperability and bridging let Hedera applications communicate and move assets across other networks so a dApp is not confined to a single chain. These integrations fall into two broad groups:

* **Cross-chain messaging protocols** that carry arbitrary data and token transfers between chains, such as [Chainlink CCIP](/evm/integrations/cross-chain/chainlink-ccip) and [LayerZero](/evm/integrations/cross-chain/layerzero).
* **Ready-to-use bridged assets** that already span multiple chains, such as [USDT0](/evm/integrations/cross-chain/usdt0), the omnichain deployment of Tether's USDT.

## Choosing an integration

Match the integration to what you are trying to do, not the other way around.

| Integration                                                    | Best for                                                                  | You deploy a contract?                                      | Under the hood                                |
| -------------------------------------------------------------- | ------------------------------------------------------------------------- | ----------------------------------------------------------- | --------------------------------------------- |
| [Chainlink CCIP](/evm/integrations/cross-chain/chainlink-ccip) | Programmable cross-chain messaging and token transfers with risk controls | Yes, integrate the CCIP router and receiver                 | CCIP messaging plus supported token transfers |
| [LayerZero](/evm/integrations/cross-chain/layerzero)           | Sending arbitrary messages or bridging your own token across chains       | Yes, an OApp/OFT contract (or HTS Connector for HTS tokens) | OFT, ONFT, OFT Adapter, HTS Connector         |
| [USDT0](/evm/integrations/cross-chain/usdt0)                   | Using a dollar stablecoin that already exists on Hedera and other chains  | No, the token is already deployed                           | HTS token; LayerZero OFT                      |
