README
sc-simnode 
I'm trying to free your mind, Neo. But I can only show you the door. You're the one that has to walk through it.
This library exists to allow substrate developers to:
-
Test complex pallets that require a full runtime, not a mocked runtime.
-
Test a combination of both onchain & offchain components (eg offchain workers)
-
Fork your live chain state and execute transactions from any origin.
-
Simulate runtime upgrades & migrations.
Documentation
Installation and integration guides can be found in the book. Example integrations are provided for runtimes of all different kinds:
- Standalone Chain, AURA leader election, GRANDPA consensus.
- Standalone Chain, BABE leader election, GRANDPA consensus.
- Parachain, AURA leader election, Polkadot Consensus.
Releases
sc-simnode exclusively follows the official paritytech/polkadot-sdk umbrella crate stable releases. Therefore new versions of this crate will be published for every major version of the corresponding polkadot-sdk stable release.
E.g polkadot-stable2412 is supported by the v2412.0.0 version of this crate. Subsequent stable releases will see a similar version bump in this crate.
