@oko-wallet/ewallet-sdk-eth

ewallet_sdk_eth

• This package is a variant of @oko-wallet/ewallet-sdk-core for Ethereum.
• It provides a way to interact with Ethereum wallets using @oko-wallet/ewallet-sdk-core.

Example

Create Wallet

import { initKeplrEwallet } from "@oko-wallet/ewallet-sdk-core";
import { initEthEWallet } from "@oko-wallet/ewallet-sdk-eth";

const eWallet = await initKeplrEwallet({
  element_id: "oko-wallet",
});

const ethEWallet = await initEthEWallet({
  eWallet,
});

Get Provider

const provider = await ethEWallet.getEthereumProvider();
const chainId = await provider.request({
  method: "eth_chainId",
});

Viem Integration

• Create a viem account

const account = await toViemAccount(eWallet);

• Create a viem client

import { createPublicClient, createWalletClient, custom } from "viem";

const provider = await ethEWallet.getEthereumProvider();

const publicClient = createPublicClient({
  chain: sepolia,
  transport: custom(provider),
});

const walletClient = createWalletClient({
  account: (
    await provider.request({
      method: "eth_accounts",
    })
  )[0],
  chain: sepolia,
  transport: custom(provider),
});

Ethers Integration

import { BrowserProvider } from "ethers";

const provider = new BrowserProvider(await ethEWallet.getEthereumProvider());

const blockNumber = await provider.getBlockNumber();

const signer = await provider.getSigner();

const signature = await signer.signMessage("Hello, world!");

Create Provider only

import { initEWalletEIP1193Provider } from "@oko-wallet/ewallet-sdk-eth";

const provider = await initEWalletEIP1193Provider({
  id: "oko-wallet",
});

or create a provider manually

import { initEWalletEIP1193Provider } from "@oko-wallet/ewallet-sdk-eth";

const provider = new EWalletEIP1193Provider({
  id: `${Date.now()}-${Math.random().toString(36).substr(2, 9)}`,
  chains: [
    {
      chainId: "0x1",
      chainName: "Ethereum Mainnet",
      nativeCurrency: {
        name: "Ether",
        symbol: "ETH",
        decimals: 18,
      },
      rpcUrls: ["https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID"],
      blockExplorerUrls: ["https://etherscan.io"],
    },
  ],
});
