Interoperability and Bridging - Hedera

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 and LayerZero.
Ready-to-use bridged assets that already span multiple chains, such as USDT0, the omnichain deployment of Tether’s USDT.

Chainlink CCIP

Programmable cross-chain messaging and token transfers with built-in risk controls. Live on Hedera Mainnet and Hedera Testnet.

interoperability-and-bridging-layerzero

LayerZero

Omnichain messaging and token bridging via the OApp and OFT standards.

USDT0

Omnichain USDT on Hedera, built on LayerZero’s OFT standard.

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	Programmable cross-chain messaging and token transfers with risk controls	Yes, integrate the CCIP router and receiver	CCIP messaging plus supported token transfers; live on Hedera Mainnet and Hedera Testnet
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	Using a dollar stablecoin that already exists on Hedera and other chains	No, the token is already deployed	HTS token; LayerZero OFT
