caution
LayerZero Testnet Endpoints use the real Mainnet pricefeed for cross-chain transfers. That means Ethereum Sepolia uses the real Ethereum gwei price. For testing EVM <> EVM transfers, it may be cheaper to use another EVM testnet with a cheaper cost of blockspace.

info

Endpoint Id (eid) values have no relation to Chain Id (chainId) values. Since LayerZero spans both EVM and non-EVM chains, each Endpoint contract has a unique identifier known as the eid for determining which chain's endpoint to send to or receive messages from.

When using LayerZero contract methods, be sure to use the correct eid listed below:

  • 30xxx: refer to mainnet chains

  • 40xxx: refer to testnet chains

To see if a specific LayerZero contract supports another, use the isSupportedEid() method.

Contract Description​

Contract NameDescription
EndpointV2The primary entrypoint into LayerZero V2 responsible for managing cross-chain communications. It orchestrates message sending, receiving, and configuration management between various smart contract connections using message library contracts and internal mappings to track OApp specific settings.
SendUln302A message library for sending cross-chain messages. It combines functionalities from SendUlnBase and SendLibBaseE2 to ensure secure message dispatch.
ReceiveUln302A message library for receiving and verifying cross-chain messages. It integrates ReceiveUlnBase and ReceiveLibBaseE2 to maintain message integrity.
SendUln301A version of the send message library compatible with EndpointV1 for backwards compatibility with EndpointV2.
ReceiveUln301A version of the receive message library compatible with EndpointV1 for backwards compatibility with EndpointV2.
LZ ExecutorA contract responsible for executing received cross-chain messages automatically with a specified gas limit and msg.value for a fee.
LZ Dead DVNRepresents a Dead Decentralized Verifier Network (DVN). These contracts are placeholders used when the default LayerZero config is inactive and will require the OApp owner to manually configure the contract's config to use the pathway.

Checking Default Configs​

To see the default configuration for a given pathway (i.e., from Chain A to Chain B), you can use LayerZero Scan's Default Checker.
