This builds on cw3-flex-multisig and instead has the voting set maintained by cw20 tokens. This allows for the cw20s to serve as governance tokens in the DAO, similar to how governance tokens work using contracts like Compound Governance.
The first step to create such a DAO is to instantiate an cw20 contract.
When creating the DAO, in addition to the cw20 conrtract address you must set the required threshold to pass a vote as well as the max/default voting period.
First, a voter with an cw20 balance must submit a proposal. The proposer can set an expiration time for the voting process, or it defaults to the limit provided when creating the contract (so proposals can be closed after several days).
Before the proposal has expired, any voter with the required cw20 token can add their vote. Only "Yes" votes are tallied. If enough "Yes" votes were submitted before the proposal expiration date, the status is set to "Passed".
Once a proposal is "Passed", anyone with the correct cw20 token may submit an "Execute" message. This will trigger the proposal to send all stored messages from the proposal and update it's state to "Executed", so it cannot run again. (Note if the execution fails for any reason - out of gas, insufficient funds, etc - the state update will be reverted, and it will remain "Passed", so you can try again).
Once a proposal has expired without passing, anyone can submit a "Close" message to mark it closed. This has no effect beyond cleaning up the UI/database.
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/cw_dao.wasm .
ls -l cw_dao.wasm
sha256sum cw_dao.wasm
Or for a production-ready (optimized) build, run a build command in the repository root: https://github.com/CosmWasm/cosmwasm-plus#compiling.
