Abridged Web Wallet Frame Provider

该提供商通过使用父 iFrame 和子 dapp web3 polyfill 将 dapps 连接到 Abridged web wallet sdk。

<代码> npm 安装@abridged/web-wallet-frame-sdk

父 iFrame 应该构造如下：

    import { FrameProvider } from "@abridged/web-wallet-frame-sdk";

    // SDK - Abridged SDK reference
    // window - browser window reference object
    // WALLET_PUB_KEY - user's web wallet public key

    let wallet = new FrameProvider(sdk, window, WALLET_PUB_KEY);

    // Set custom UI transaction prompt
    wallet.setPrompt( function(msg, approve, reject) {
        var retVal = confirm("Do you want to continue? Transaction: " + msg);
        // Approve transaction
        if(retVal) approve();
        // Reject transaction
        else reject();
    });

    // Allows the dapp to request on/off ramp flow to trigger in the web wallet
    // Can optionally be provided erc20 address to onramp directly to token if possible
    // Handler is async to allow for waiting on on/off ramp completion
    wallet.setRamp( aysnc function(action, token) {
        if(action==="buy") {
            if(token === null) console.log('wants to buy eth");
            else console.log('wants to buy", token);
        }
        if(action==="sell") {
            if(token === null) console.log('wants to sell eth");
             else console.log('wants to buy", token);
        }
        return true; // if successful
    });

    // The setup function will change the iFrame object src to the target location and start listening for web3 calls from child.
    //
    // refiFrame - current iFrame reference to iFrame dom object
    // frameSrc - url for the IFrame to load once provider is loaded

    await wallet.setup(refiFrame, frameSrc);

    // Be sure to call this if your React component unloads or redraws
    wallet.destroy();

子 iFrame 应该导入 polyfill：

import '@jadbox/iframe-provider-polyfill'

或通过 html 添加：

<script src="https://cdn.jsdelivr.net/npm/@jadbox/iframe-provider-polyfill/dist/index.js" type="text/javascript"></script>
