CW20 Basic

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:

• [x] CW20 Base
• [ ] Mintable extension
• [ ] Allowances extension

Running this contract

You will need Rust 1.41+ 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 (not currently working with this monorepo...)

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/rust-optimizer:0.8.0 ./contracts/cw20-base mv contract.wasm cw20_base.wasm

Importing this contract

You can also import much of the logic of this contract to build another ERC20-contract, such as a bonding curve, overiding or extending what you need.
