Ale Wallet Developers

The Ale wallet development API and example codes.
The Ale wallet (Chrome Extension) API
The Ale wallet API provides tools for web developers interacting with MCP, the blockchain layer of CCN. The developers can use the API to transfer crypto assets, deploy smart contracts, and build dApps on MCP.
The Ale wallet provider's name is "aleereum".
Check if Ale wallet is installed
typeof window[“aleereum”] !== “undefined”
const provider = window[“aleereum”]
Check if Ale wallet is connected
const isConnected: boolean = provider.isConnected
Check if Ale wallet is locked
const islocked: boolean = provider.islocked
Get current network Id
const networkId: string = provider.networkId
NetworkId = 1: Mainnet (Under development)
NetworkId - 2: Dome-A Testnet
NetworkId = 3: Huygens Testnet
Get current account
const account = provider.account
Get an account balance
interface result {
	success: boolean
	balance: number
	msg: string
}
const balance: Promise<result> = provider.getBalance(account)
Connect or unlock the wallet
const connectStatus: Promise<boolean> = provider.connect()
Listen to the change of account
provider.on("on_account_change", (account) => console.log(account))
Listen to the change of networkId
provider.on("on_networkId_change", (networkId) => console.log(networkId))
Listen to the change of isConnected status of the wallet
provider.on("on_isConnected_change", (isConnected) => console.log(isConnected))
Listen to the change of lock/unlock status of the wallet
provider.on("on_islocked_change", (islocked) => console.log(islocked))
Examples
Vue.js example code
// ale.js
import store from "./store";
​
window.onload = function() {
  if (typeof window.aleereum !== "undefined") {
    const provider = window["aleereum"];
​
    if (provider.isAle) {
      store.commit("IS_ALE", true);
      store.commit("M_SET_DAPP_ACCOUNT", provider.account);
      store.commit("M_SET_DAPP_CONNECT", provider.isConnected);
      store.commit("M_SET_DAPP_NETWORK", provider.networkId);
      store.commit("IS_ALE_ENABLED", !provider.islocked);
​
    } else {
      store.commit("HAS_ALE", false);
    }
  } else {
    store.commit("IS_ALE", false);
  }
};
​
​
// App.vue
export default {
    mounted(){
        this.listenDataChange();
    },
    methods: {
        handleNetworkChange(networkID) {
          this.$store.commit("M_SET_DAPP_NETWORK", networkID);
        },
        handleLockChange(status) {
          this.$store.commit("IS_ALE_ENABLED", !status);
        },
        handleConnectChange(status) {
          this.$store.commit("M_SET_DAPP_CONNECT", status);
        },
        handleAccountChange(account) {
          this.$store.commit("M_SET_DAPP_ACCOUNT", account);
        },
        listenDataChange() {
          window.aleereum.on("on_networkId_change", this.handleNetworkChange);
          window.aleereum.on("on_islocked_change", this.handleLockChange);
          window.aleereum.on("on_isConnected_change", this.handleConnectChange);
          window.aleereum.on("on_account_change", this.handleAccountChange);
        },
    },
}
Send a transaction to smart contract
import Mcp from "mcp.js";
​
const abi = require("./abi.json");
​
const mcp = new Mcp();
​
mcp.Contract.setProvider(https://huygens.computecoin.network);
​
const core = "0xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";  // contract address
​
const Contract = new mcp.Contract(abi, core);
​
// Query
Contract.methods.xxx().call()
.then(res => {
    console.log(res.toString());
})
​
// Transaction
Contract.methods.xxx().sendToBlock({
    from: account,
    amount: "0"
})
.then(res => {
    if(!res) {
        throw new Error("Transaction Failed.")
    } else {
        const hash = res.msg;   // blockHash
    } 
})
