How to use the Cronos Bridge to cross-chain?

Everything you need to know about bridging from Cronos.

The native chain “gas” token on Cronos is CRO. All transactions on Cronos are paid in CRO. This includes bridging “cross-chain” transactions to the other chains “networks”.

When you bridge from Cronos to another chain, a small faucet “gas token” will be airdropped  for your first transaction on the destination chain.


What is Cronos?

Cronos is the Cosmos SDK based EVM compatible chain running in parallel to the Chain . It aims to massively scale the Chain DeFi ecosystem, by providing developers with the ability to rapidly port apps from Ethereum and EVM-compatible chains, with funding from Particle B’s $100m EVM fund and access to the 10M+ user base of the ecosystem.


How to configure MetaMask for Cronos?

You have 2 options to configure MetaMask for using the Cronos “network”:

  1. Automatic by selecting the Cronos chain in the RelayChain bridge app. This will import the network settings into metamask.
  2. Manually by adding the following Cronos network settings to Metamask:

          Network Name:  Cronos Network
          New RPC URL:
          Chain ID: 25
