Testnet Addresses

Supported Chains (Testnet)To send and receive messages, LayerZero endpoints use a chainId to identify different blockchains. Below is a table of the supported test networks along with their unique chainId.​Review carefully. LayerZero assigns proprietary IDs to each chain.

Official Endpoint Addresses (TESTNET)

Note: chainId values are not related to EVM IDs. Since LayerZero will span EVM & non-EVM chains the chainId are proprietary to our Endpoints.
These are the addresses of the contracts on which you would call send()
By the way, if you want to go straight to mainnet, look no further.
