EVM compatible networks
How to integrate with D'CENT wallet for dapps on EVM compatible networks.
D'CENT mobile app's in-app browser injects
window.ethereum as a provider. If your dapp is based on EVM compatible network, you can interact with D'CENT wallet through window.ethereum provider.The following is the D'CENT in-app browser's supported network list which can use
window.ethereum provider. Additional networks (https://chainid.network/) will be added to this list in the future.Chain ID | Network |

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

D'CENT 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 D'CENT wallet.
For your reference, you can also find the MetaMask's developer guide in the link below.
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");
}
Most of dapp browsers for EVM networks use the same interface
window.ethereum. You can check whether the dapp browser is D'CENT wallet's in-app browser with the following code.if (window.ethereum.isDcentWallet === true) {
console.log("It's D'CENT wallet's in-app browser")
}
You can use the following code in order to connect to D'CENT wallet's account.
ethereum.request({ method: 'eth_requestAccounts' })
You can also use the old style code.
ethereum.enable()
If the connection to wallet is requested, you can see the popup like below.
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
To get the address of the current account, you can use the following code.
ethereum.request({ method: 'eth_accounts' })
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],
});
