KROSS

Kross brings Across Protocol’s intent-based interoperability to Kadena so developers and users can move liquidity seamlessly between Kadena and top EVM chains/L2s (Ethereum, Arbitrum, Optimism, Base, Polygon, zkSync) and tap non-EVM routes where Across supports them (e.g., Solana, Aleph Zero, Lisk). Across achieves fast fills via a competitive relayer network and settles trust-minimised using UMA What we built Open-source Kurtosis package for Across: A modular package that spins up an Across stack and parameterises deployments across devnet/testnet/mainnet. Kurtosis is purpose-built for packaging blockchain infra so teams can launch complex environments consistently - even on k8s or Docker - with one-liners. (We model our approach on widely adopted packages like Ethereum CDK.) Kadena adapter: A thin integration that lets a Kadena (Pact or Chainweb EVM) app express a cross-chain intent that Across relayers can quote, claim, and fill. On fulfillment, Across settles and repays relayers on the destination chain.

I implemented a Kadena-to-EVM cross-chain bridge by integrating Across Protocol’s intent-based architecture, with deployment and orchestration automated via Kurtosis.

Built a Kadena adapter enabling cross-chain intents to EVM networks, leveraging Across Protocol for relayer-based fulfillment and Kurtosis for reproducible multi-chain deployments.

Developed a bridging solution on Kadena that emits cross-chain intents consumable by Across relayers, orchestrated through Kurtosis for automated deployment and testing across EVM chains.
