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.
