Installing The Canvas Node

We need to use a Canvas node with the built-in Contracts module. For this workshop we'll use the pre-designed Substrate node client.

cargo install canvas-node --git https://github.com/paritytech/canvas-node.git --tag v0.1.8 --force --locked

Install binaryen

binaryen(version >= 99) is used to optimize the WebAssembly bytecode of the contract.

download a binary release directly

tar -xvf binaryen-version_101-x86_64-linux.tar.gz  
sudo cp binaryen-version_101/include/* /usr/include/  
sudo cp binaryen-version_101/lib64/* /usr/lib64/  
sudo cp binaryen-version_101/bin/* /usr/bin/

Install cargo-contract

cargo-contract is the ink! command line utility which will make setting up Substrate smart contract projects easier.

cargo install cargo-contract --vers ^0.12 --force --locked
