Stateset Contracts

Core smart contracts for the Stateset Blockchain.

Prerequisites

Before starting, make sure you have rustup along with a recent rustc and cargo version installed. Currently, we are testing on 1.58.1+.

And you need to have the wasm32-unknown-unknown target installed as well.

You can check that via:

rustc --version
cargo --version
rustup target list --installed
# if wasm32 is not listed above, run this
rustup target add wasm32-unknown-unknown

Contracts

Here are a number of useful contracts that either implement or consume the interfaces defined in packages/stateset-*.

Creating a new contract

Use cosmwasm-template as a basis

cd contracts
cargo generate --git https://github.com/CosmWasm/cosmwasm-template.git --name PROJECT_NAME
cd PROJECT_NAME
rm -rf .git
rm .gitignore
rm .cargo-ok
git add .

Compiling and running tests

Now that you created your custom contract, make sure you can compile and run it before making any changes. Go into the repository and do:

# this will produce a wasm build in ./target/wasm32-unknown-unknown/release/YOUR_NAME_HERE.wasm
cargo wasm

# this runs unit tests with helpful backtraces
RUST_BACKTRACE=1 cargo unit-test

# auto-generate json schema
cargo schema
