Cardano has launched its first live on-chain inter-blockchain communication (IBC) connection with layer-1 blockchain Injective on a testnet, enabling users to send ADA to Injective and move INJ back to Cardano. The Cardano Foundation and Injective called it the start of a new era of interoperability but said it remains experimental. The setup supports only Cardano Preprod and the Injective testnet using valueless test tokens.

Secret Network has proposed moving from Cosmos to Ethereum layer2 Arbitrum, citing security risks tied to AI-enabled vulnerability exploitation and a weakening Cosmos ecosystem. It has run privacy-protecting smart contracts on Cosmos since 2020, but said older code has become easier to analyze and cheaper to attack using AI. The June Axelar-Secret IBC bridge exploit was also cited as a factor.
