Run a Substrate Node

Ask! contracts can be deployed to any substrate-based blockchain that supports the pallet-contracts.

substrate-contracts-node

The substrate-contracts-node is a simple Substrate blockchain which is configured to include the contracts module.

It's a comfortable option if you want to get a quickstart.

After successfully installing substrate-contracts-node, you can start a local development chain by running:

cd substrate-contracts-node

cargo build --release

./target/release/subtrate-contracts-node --dev -d dev

You should start to see blocks being produced by your node in your terminal once you start to send transactoins.

You can interact with your node using the Polkadot Apps.

Now configure the UI to connect to the locally running node:

• Click on the dropdown selector at top left corner.
• Choose the Local Node.

Europa

Europa is a sandbox to run and debug smart contracts for pallet-contracts module.
