After learning more about try-runtime a few weeks ago, I was thinking of a tool that could be useful for wallets/application developers. In brief, it would simulate the entire Polkadot network (including all parachains) for developers to test against, similar to Hardhat for Ethereum contract develop…

Chopsticks already supports fork relay chains and it is part of the plan to make it support multiple networks so we can test XCM with it Support multiple networks · Issue #20 · AcalaNetwork/chopsticks · GitHub . The goal of Chopsticks is to be able to one command fork the mainnets so we can run test…

The framework I have in mind is not for end users, it is for developers. The main point is that with just a Wasm host and K-V store, developers would not need to run nodes for every parachain they want to interact with. This is why I used “Polkadot simulator” and the comparison with Hardhat.* Sorry…

You are describing Chopsticks. The plan is with one config file, it can fork the relaychain + multiple parachains. All without actually running any Substrate node. Smoldot will be used to execute the wasm runtime, which itself already supports running light clients for multiple chains so we know it…

In that case, awesome. I still don’t see why you need to run a client at all, why not just an emulator? From reading the Chopsticks thread, though, I really understood that it’s a tool for parachain runtime developers, not application developers, which is why I started a separate thread. If it is f…

It doesn’t run a real client. It does use smoldot as the wasm executor but without all the real client part. e.g. there is no any p2p functionality. Chopsticks implements a test client by implementing the Substrate JSONRPC. Or in other words, it emulates a client. We have expanded the scope of Chop…

I think a great end goal that can be envisioned for Chopsticks is to run something like: chopsticks --relay relay.wasm --para para1.wasm --para2.wasm --block-time 0.1s This will be a massive unlock for Runtime builders, and JS/CAPI/SubXT developers wishing to test their offchain applications in a…

[image] kianenigma: How far is Chopsticks from this? From the chopsticks README: npx @acala-network/chopsticks@latest xcm -r kusama -p karura -p statemine I used it a while back and it worked alright.

We are already using Chopsticks to write xcm e2e tests GitHub - AcalaNetwork/e2e-tests
