Debugging and testing cross-chain and multi-chain transactions require the right tools and frameworks that can support your development process. Depending on your needs and preferences, you can choose from a variety of options, such as:
- Truffle : a popular development environment, testing framework, and asset pipeline for Ethereum and other EVM-compatible blockchains. It allows you to write, compile, deploy, and test smart contracts, as well as interact with them via a console or a graphical interface.
- Ganache : a personal blockchain for Ethereum development that you can use to run tests, execute commands, and inspect state while controlling how the chain operates. It also supports forking from any live network, which can be useful for simulating cross-chain scenarios.
- Polkadot/Substrate : a platform for building and connecting blockchains that can interoperate with each other via the Polkadot relay chain. It provides a modular framework for creating custom blockchains with various features, such as consensus, governance, or smart contracts. It also offers tools for testing and debugging, such as Polkadot-JS , Substrate-Node-Template , or Substrate-Front-End-Template .
- Cosmos/Tendermint : a network of independent blockchains that can communicate with each other via the Inter-Blockchain Communication (IBC) protocol. It enables developers to create sovereign blockchains with different applications and governance models, while leveraging the security and scalability of the Cosmos Hub. It also provides tools for testing and debugging, such as cosmos-sdk , gaia , or starport .
