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.
