Release v1.0.0

We are excited to announce the release of Version 1.0.0 of our contract suite, designed to facilitate seamless communication between the Icon and Cosmos based blockchains using the Inter-Blockchain Communication (IBC) protocol. This release marks a significant milestone for ICON in achieving cross-chain interoperability, enhancing the capabilities of both ecosystems.

Major Highlights

• Fully supports IBC protocol
• Enhanced security via Light Clients
• Now custom chains that do not have IBC module integrated can also connect via our contract suite
• Examples and Implementation projects included as well for reference
• Connect to ICON via any Cosmos based chains
