The Inter-Blockchain Communication protocol (IBC) is an inter-module communication protocol that bridges different blockchains to facilitate communication and feature exchanges between networks with different infrastructure designs and consensus algorithms. IBC transfer works among the IBC-enabled chains, and it has been enabled in Cronos POS Chain.
In the following step-by-step guide, you will learn how to make IBC transfers with Keplr, and IBC transfers between Cronos POS Chain and Cosmos are demonstrated as an example in this guide.
Make sure you have CRO under Cronos POS Chain and ATOM under the Cosmos network in Keplr.
You will need your Cronos POS Chain and Cosmos addresses in Keplr, please copy-and-paste somewhere and make them handy for later use.
