How to Switch the Network​

By clicking the "network" icon on the right top corner of "discovery" tab, you can switch the blockchain network for dapp browser.

For more details, please see DCENT user guide.

If your dapp is already integrated with MetaMask​

DCENT wallet's provider uses EIP-1193 & EIP-1102 interface.

MetaMask also uses the same provider interface (not exactly the same, but almost the same). This means if your dapp is already integrated with MetaMask, it's very easy to integrate with DCENT wallet. For your reference, you can also find the MetaMask's developer guide in the link below.

How to detect in-app browser​

In order to check if your dapp running on EVM networks is supported by the dapp-browser, you need to check whether window.ethereum is defined.

if (typeof window.ethereum !== 'undefined') {
    console.log("It's in-app browser");
}

How to check DCENT provider​

Most of dapp browsers for EVM networks use the same interface window.ethereum. You can check whether the dapp browser is DCENT wallet's in-app browser with the following code.

if (window.ethereum.isDcentWallet === true) {
    console.log("It's DCENT wallet's in-app browser")
}

Connect to Wallet​

You can use the following code in order to connect to DCENT wallet's account.

ethereum.request({ method: 'eth_requestAccounts' })

You can also use the old style code.

ethereum.enable()

Wallet Connection UI​

If the connection to wallet is requested, you can see the popup like below.

Get the current network​

To get the current network ID, you can use the following code.

ethereum.request({ method: 'net_version' })

You can also use the old style code.

ethereum.networkVersion

Get the current account's address​

To get the address of the current account, you can use the following code.

ethereum.request({ method: 'eth_accounts' })

Send Transaction​

By using ethereum.request method to call eth_sendTransaction, you can send the transaction. The following is the example code to show how to send the transaction.

const transactionParameters = {
  nonce: '0x00', // ignored
  gasPrice: '0x9184e72a000', // customizable by user
  gas: '0x76c0', // customizable by user
  to: '0x0000000000000000000000000000000000000000',
  from: '0xb60e8dd61c5d32be8058bb8eb970870f07233154', // current account's address
  value: '0x9184e72a',
  data: '0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675',
};

const txHash = await ethereum.request({
  method: 'eth_sendTransaction',
  params: [transactionParameters],
});
