NEAR Smart Contract Rust Template

Project structure for writing smart contracts for NEAR in Rust.

Required Software

• Rust & Cargo
  • With the WASM target installed: rustup target add wasm32-unknown-unknown
  • cargo-make: cargo install cargo-make

Usage

Scripts

cargo make clean

Removes the target and neardev directories.

cargo make test

Runs unit tests using the default target. (Note: behavior may differ from simply running cargo test depending on the target specified in .cargo/config.toml.)

cargo make build

Compiles the smart contract to a WebAssembly binary. The binary path is ./target/wasm32-unknown-unknown/release/<package>.wasm.

cargo make optimize

Cleans up and optimizes the most recently-built WASM binary. The optimized binary path is ./deploy/<name>.wasm.

Note: In order to optimize the WASM binary, you must have wasm-tools installed:

cargo install wasm-tools

wasm-tools is also available on Homebrew:

brew install wasm-tools
