This is an implementation of the ERC721 specification in Vyper. It was done as a learning excercise, and has not been audited. Moreover, due to certain limitations of Vyper (see TODOs below), the implementation doesn't yet comply with the specification.
npm i
npm run test
If you make any modifications to the contracts, you will need re-compile:
npm run build
A truffle compatible build process is handled by truper
, which does not include vyper compiler. You will need to have the vyper
compiler installed and available in your terminal's environment. If you can't run $ vyper -h
, the build process will fail.
See the Vyper installation instructions.
- Implement the
safeTransfer()
function with data. (Dependent on adding default parameter values in vyper). Currently it is implemented but namedsafeTransferWithData()
. - Add a test for the ability to send from
safeTransferWithData()
- Add the erc721 MetaData interface
- Add the erc721 Enumberable interface
The test suite used here is taken from 0xCert's ethereum-erc721, with only minor modifications. Thank you to them for their work.
