Cairo 1.0-Alpha.2 — New Release is Coming
- We are releasing Cairo 1.0-alpha.2, which brings a host of new features to the language
- It is now possible to implement an ERC20 contract
- Those new linguistic features will be applicable in the upcoming StarkNet-v0.11.0 version
Fresh New Features!
Cairo 1.0 is continuing its fast improvement pace. Today’s release introduces, among other things, all the necessary features to write an ERC-20 contract.
To mention some of the new features:
- Events in contracts
- Mapping storage variables
- Trait support
- Type inference
See the complete list in the GitHub repository.
Let’s have a look at an example of an ERC20 contract (the full concrete example is, of course, on GitHub) to demonstrate a use case of an event and mappings in the storage:

We continue to work on two parallel vectors:
- Evolve Cairo 1.0 at full speed towards full-feature compatibility with the old Cairo.
- Develop Starknet v0.11.0 that will support contracts written in Cairo 1.0
In the meanwhile, we encourage devs to start writing with Cairo 1.0 and getting familiar with it.
