CrossFund

Cross-chain funding platform powered by CosmWasm Neutron-SDK and IBC

Proposal Submission:

SubmitProposal {
  title: String,
  description: String,
}

Simple operation that serves to propose a project to indicate interest towards a certain project missing in the ecosystem. Can be initiated by anyone including parties interested in funding a project or and development teams as a requirement for the following steps.

Currently anyone can create a proposal on a chain where the contract is deployed. Cross-chain creations should be possible using IBC-hooks.

Possible changing towards following Cosmos MsgSubmitProposal (add metadata, description -> summary)

Proposal Funding:

FundProposal {
  proposal_id: u64,
  auto_approve: Option<bool>,
}

Send funds towards any existing proposal. The funds are held in custody of the contract and redeemable at any point except for when they are locked for a specific prorpsal application and accepted.

auto_approve field will be explained later

Submitting an application:

SubmitApplication {
  proposal_id: u64,
  description: String,
  application: ApplicationSubmission {
    applicants: Vec<{ address, share }>,
    auditors: Vec<{ address, share }>,
    deliver_by: Expiration,
}

Create an application for a proposal. Each application nust submit a list of applicant addresses and their shares from proposal funding and list of independent auditors with their shares for work verification. It's up to community to decide whether the applicant and auditers are quialifed for a task.

Submitting an application:

ApproveApplication {
  proposal_id: u64,
  application_sender: Addr
}

Targets all deposited funds of sender towards a specific application. If auto_approve is set when funding they will be auto-approved for a an application that has more than the half of all the funds deposited for a proposol (per token denom currently)

Accepting work on proposal:

AcceptApplication {
  proposal_id: u64,
  application_sender: Addr
}

A message send by application senders meant when they are ready to work on a proposal. As soon as submitted all the funds approved for an application are becoming locked until auditors submit confirmation message or until application expiration date. Funds send towards a proposal with auto_approve field will be also locked at this point if more than half of the funds were approved for an application.

Application Verification

VerifyApplication {
  proposal_id: u64,
  application_sender: Addr
}

A message send by each application auditor when they are notified about delieverables and verify them. As soon as each auditors sunmit the message the funds are being released to all of the application shareholders.

Building Contract

RUST_BACKTRACE=1 docker run --rm -v "$(pwd)":/code \ --mount type=volume,source="dev_cache_template",target=/contracts/template/target \ --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \ cosmwasm/workspace-optimizer:0.13.0 ./contracts/template

Name your built wasm file crossfund.wasmand put it inside contracts directory for integration testing

Running integration tests

Follow this guide for setting up a local envieronment https://docs.neutron.org/tutorials/integration-tests

After finishing installatiion you can put the directory of this repository as a sibling to other 4 if you wish to run the tests with docker using yarn test

Alternatively run make start-cosmopark in setup folder of git@github.com:neutron-org/neutron-integration-tests.git

and then in this repository: NO_DOCKER=1 yarn test
