Ethereum Tax Dodgeball

Tag friends or strangers with tax liability with or without their knowledge.

Only U.S. taxpayers can be tagged, but anyone in the world can tag a U.S. taxpayer.

See the IRS guidance on this process here.

Usage

A dapp is available to interface with the smart contract.

Contracts have been deployed by a non U.S. person at the following addresses:

network	address
Ethereum Mainnet	0xe15dcc5Bce1AF8909e0250325221fb13b683660e
Ropsten Testnet	0xFc1248A6Aff0d4d5400061367D441323eBEE3cB5

Opt-out

A taxpayer with a healthy fear of the law may choose to opt out of participation. Simply call the optOut function and include in the transaction a sum of ether greater than or equal to the opt-out fee.

Development

Development and testing with the default network require that a local blockchain be run in a separate terminal window:

yarn run ganache

Alternatively, some buidler commands will work if an in-process network is specified instead:

yarn test --network buidlerevm

Contracts

To compile and test contracts:

yarn test

To include a gas usage report:

REPORT_GAS=true yarn test --network localhost

One of the tests tends to fail, perhaps due to a race condition. It's good enough for government work.

Interface

The static site is built with Saber.

To deploy contracts and serve static site in development mode:

yarn run dev

To build and deploy static site to gh-pages:

yarn run deploy

Contract Deployment

To deploy contracts to an arbitrary network, set the URL and MNEMONIC environment variables and run the deploy script with generic network configuration via buidler:

URL="http://localhost:8545" \
MNEMONIC="melody exact hedgehog pulse parade edge school eight invite doll luggage injury" \
npx buidler run scripts/deploy.js --network generic
