# Supported Chains

The core infrastructure of Glacis is deployed across the following chains. Each deployment undergoes integration testing to ensure that all Glacis operations function correctly on the respective chain and with the actual GMPs.

Testnet chains only communicate with other Testnet chains while Mainnet chains only communicate with other Mainnet chains.
