Supported Networks
VIA Labs supports cross-chain communication across 140+ mainnets and 80+ testnets, including both public and private networks.
The tables below list the VIA Gateway contract address for each network with a live VG-1 deployment. Pass the gateway address for your network to setMessageGateway() when configuring your contract.
VIA uses standard EVM chain IDs — the same value returned by eth_chainId on each network. Use these as the destChainId in messageSend() and in setMessageEndpoints().

Additional mainnet gateways are being rolled out — this table is updated as each deployment goes live.
Cardano and Midnight integrations are in development and use a different client architecture — see the Cardano and Midnight pages.
