Networks

Reef chain's networks.

Reef mainnet

The Reef mainnet is launching in “canary” mode. Reef chain is not just an Ethereum clone - is built from ground up with new blockchain technology, and as such carries risk of potentially disruptive bugs.

While Reef chain is in “canary” mode, the chain might have to be reset in the event of catastrophic failure, and only REEF account balances at the time of the failure would carry over to the new network.

Reef testnet

Reef testnet is a common playground for deploying and testing DeFi apps. It is recommended to first deploy apps on the testnet before launching on mainnet.
