Developed and integrated WeaveVM Data Availability (DA) support into the dymensionxyz/dymint and dymensionxyz/rollapp-evm repositories, expanding data availability options and enhancing interoperability for blockchain applications. The work involved implementing new DA clients, RPC interfaces, signer components, and configuration options using Go and Shell scripting, with a focus on cryptography and blockchain integration. Comprehensive tests and updated documentation were provided to facilitate adoption and reduce onboarding friction. These enhancements enabled both Dymint and RollApp to utilize WeaveVM infrastructure for submitting and retrieving data, strengthening multi-provider support and improving data availability resilience for production deployments without introducing provider lock-in.
