Development Workflow

Create a new NEAR project

# initialise new rust project 
cargo new project_name 

# install near dependencies 
cargo add near_sdk 
cargo add near-contract-standards
cargo add near-sdk-contract-tools

# alternatively, if cargo.toml file with necessary dependencies exists:
cargo fetch 

# build contract files 
cargo build --release --target wasm32-unknown-unknown

# deploy to testnet 
near dev-deploy --wasmFile target/wasm32-unknown-unknown/release/contract.wasm 

Config for cargo.toml
