# Configure the compatible rust toolchain
rustup toolchain install nightly-2023-02-07
rustup component add rust-src --toolchain nightly-2023-02-07
rustup target add wasm32-unknown-unknown --toolchain nightly-2023-02-07

cargo +nightly-2023-02-07 contract build --release --manifest-path bucket/Cargo.toml

Note: if you are encountering errors during build process, they may be related to your specific processor's architecture. If this is the case, try out the Instalation using Docker image option, described in the official docs

Deployment

Generated artifacts will be located in the ./target/ink folder. Go to Devnet, select the Developer -> Contracts tab, and click the Upload & deploy code button. Use the .contract file for deployment.

Additionally, there are scripts that allow you to deploy contracts from your local environment to remote network. Check the guide for more details.

Environment tested with deploy:

• EDC-1
• Devnet
• QAnet
• Testnet
