This repository contains Substrate's node-template configured to include Substrate's pallet-contracts ‒ a smart contract module.

This repository is tracking Substrate's master.

Follow the official installation steps to set up all Substrate prerequisites.

Afterwards you can install this node via

cargo install contracts-node --git https://github.com/paritytech/substrate-contracts-node.git --force --locked

The --locked flag makes the installation use the same versions as the Cargo.lock in those repositories ‒ ensuring that the last known-to-work version of the dependencies are used.

The latest confirmed working Substrate commit which will then be used is 3cad018bb4d8129f7ff199c3a5bb63ac78b19d6b.

To run a local dev node execute

substrate-contracts-node --dev

A new chain in temporary directory will be created each time the command is executed. This is the default for --dev chain specs. If you want to persist chain state across runs you need to specify a directory with --base-path.

To have only errors and contract debug output show up on the console you can supply -lerror,runtime::contracts=debug when starting the node.

Important: Debug output is only printed for RPC calls or off-chain tests ‒ not for transactions!

See our FAQ for more details: How do I print something to the console from the runtime?.

Once the node template is running locally, you can connect to it with the Polkadot-JS Apps frontend to interact with your chain. Click here to connect the frontend to your local node.
