Mintable Synthetic Nouns

Synthetic nouns are nouns that are generated using the hash of the claimer's address as a seed. There exists one per address.

Governance

Snapshot can be used for governance using the synthetic-nouns-with-claimer strategy. The strategy gives an address that still owns the synthetic noun that they minted the ability to vote on Snapshot.

Run node

yarn hardhat node

Optionally export ABIs:

yarn hardhat deploy --export ./client/src/deployments.json --network localhost

Use FORK=mainnet to fork mainnet on the localhost network.

Tests

Run node

FORK=mainnet yarn hardhat node --no-deploy

yarn hardhat test --network localhost

Test on mainnet fork

Run mainnet fork node

FORK=mainnet yarn hardhat node --no-deploy

Copy mainnet deployments to localhost deployments

cd deployments &&
mkdir localhost &&
cp -r ./mainnet/ ./localhost/ &&
cd ..

Run tests

FORK=mainnet yarn hardhat test --network localhost

Client

Start node

FORK=mainnet yarn hardhat node --no-deploy

Copy mainnet deployments to localhost deployments

cd deployments &&
mkdir localhost &&
cp -r ./mainnet/ ./localhost/ &&
cd ..

Update deployments file

yarn hardhat deploy --export ./client/src/deployments.json --network localhost

Deployment

yarn hardhat deploy

Verify on etherscan

yarn hardhat etherscan-verify --network mainnet

Generate types

yarn hardhat typechain

Future improvements

• Expose generateSeed function
• Address preview should return data URL instead of just b64 encoded svg
• Update @notice of generateSeed and claim methods in smart contract
• Use ERC721Enumerable to get all the tokens owned by an address
• Add a mapping to see if a token is still owned by its original minter
• Add a function which lets you claim a token for another address and have it sent to that address
