StarkNet JS
- 1. StarkNet.js 101 Sean, in collaboration with March 2022
- 2. How did I get involved with StarkNet? ● Looking for a long term ETH scaling solution ● Wanted to build a web application ● No library for web applications to interface with StarkNet 2
- 3. What is StarkNet.js? ● Allow JavaScript programs, like Web and Mobile Apps to interface with the StarkNet network ● Follows ethers.js architecture in Ethereum ● Primary APIs are Providers, Account, Signer, and Contract 3
- 4. Starknet.js V3 API - Overview ● Provider ● Account ● Signer ● Contract 4
- 5. Provider The Provider API allows you to interface with the StarkNet network, without signing transactions or messages. Typically, these are read calls on the blockchain. API 5
- 6. Account An Account extends Provider and inherits all of its methods. It also introduces new methods that allow Accounts to create and verify signatures with a custom Signer. This API is the primary way to interact with an account contract on StarkNet. API 6
- 7. Signer The Signer API allows you to sign transactions and messages, and also allows you to get the public key. API 7
- 8. Contract Contract API can do data transformations in JavaScript based on an ABI. They can also call and invoke to StarkNet through a provided Signer. Contracts allow you to transform Cairo values, like Uint256 to BigNumber. It could also allow users to pass their own transformers, similar to JSON.parse. API 8
- 9. Account x ERC20 Example Code & Demo https://github.com/0xs34n/starknet.js-workshop 9
- 10. Starknet.js V3 Release ● Starknet.js V3 will be released tomorrow with a new API ○ Try it today with npm install starknet@next ● New docs to be released at starknet.js.com!
