Initial Roadmap

• (Progress) Move CAW Actions to a single-responsability SDK
• (Progress) Implement On-chain smart contract actions
• (Pending ) Set up Orbit-DB as a second source of truth
• (Pending ) Document the SDK and its usage (Examples, Snippets, DocSite, etc)

Reasoning

• Framework agnostic, so it can be used in any project.
• Leverage the SRP to speed up CAW Frontends
• Rely on Wallet Providers so the SDK doesn't have to deal with them.
• Define a structured pattern of saving and sharing data across many frontends.
• Encourage communities to build their own interfaces to unleash their creative potential.
• Provide a way to interact with the CAW smart contracts in a simple way.

Getting Started

Alpha version of the SDK might suffer breaking changes

    npm i @cawmmunity/caw-js-sdk

Setup on your project

    import { Config } from "@cawmmunity/caw-js-sdk";

    // Initialize the SDK, jsonRpcUrl is the primary provider and the other two fallbacks.
    Config.init({
      jsonRpcUrl: AppEnvSettings.jsonRpcUrl,
      infuraApiKey: AppEnvSettings.keys.INFURA_API_KEY,
      alchemyApiKey: AppEnvSettings.keys.ALCHEMY_API_KEY,
      network: 'goerli',
});

Mint a username

    import { CawNameMinterService, CawNamesService, MintableCawService, WalletBalanceService } from '@cawmmunity/caw-js-sdk/dist/services';

    const provider  = {};// Your provider here
    const signer    = {};// Your signer here
    const userName = 'cawmmunity';


    const cawMinterContract = new CawNameMinterService(provider, signer);
    const mintableCawContract = new MintableCawService(provider, signer);

    const costInCaw  = await cawMinterContract.getCostOfName(userName);

    // Mint the amount of mCAW needed to mint a username (Only during tesnet)
    await minterContract.mintMCAW({
        amount: costInCaw,
        userAddress: walletAddress,
        onEmit: (m, e) => {...}
      });

    // Approve the mCAW to be spent (Approve CAW tokens to be spent on mainnet)
    await mintableCawContract.approveMCAW({
      amount: costInCaw,
      onEmit: (m, e) => {...}
    });

    // Mint the username
    const { tx, gas, receipt } = await cawMinterContract.mintUserName({
        userName,
        onEmit: (e) => {...}
      });

Get the usernames of a wallet

    const walletAddress = '0x...';
    const fetchAvatar =true; // SVG Avatar
    const provider = {};// Your provider here
    const signer = {};// Your signer here

    const cawNamesContract = new CawNamesService(provider, signer)
    const usernames = await cawNamesContract.getTokens(walletAddress, fetchAvatar);

Validate

    const userName = 'cawmmunity';
    const isValid =  await cawMinterContract.isValidUsername(userName);

    // Many of the smart contract functions have already been written in the SDK.

There are more to come and much moe to document. Stay tuned!
