This is a basic implementation of a cw20 contract. It implements the CW20 spec and is designed to be deloyed as is, or imported into other contracts to easily build cw20-compatible tokens with custom logic.
Implements:
- CW20 Base
- Mintable extension
- Allowances extension
You will need Rust 1.44.1+ with wasm32-unknown-unknown target installed.
You can run unit tests on this via:
cargo test
Once you are happy with the content, you can compile it to wasm via:
RUSTFLAGS='-C link-arg=-s' cargo wasm
cp ../../target/wasm32-unknown-unknown/release/cw20_base.wasm .
ls -l cw20_base.wasm
sha256sum cw20_base.wasm
Or for a production-ready (compressed) build, run the following from the repository root:
docker run --rm -v "$(pwd)":/code \
--mount type=volume,source="cosmwasm_plus_cache",target=/code/target \
--mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
cosmwasm/workspace-optimizer:0.12.6
The optimized contracts are generated in the artifacts/ directory.
