Examples

With the Ethereum Provider, you can call JavaScript API specified in EIP-1193, similar to calling MetaMask functions via window.ethereum. For example,

1. Send a transaction

const provider = await connector.getProvider();
await provider.request({
  method: 'eth_sendTransaction',
  params: [
    {
      from: address, // The user's active address.
      to: address, // Required except during contract publications.
      value: '0xE8D4A50FFD41E', // Only required to send ether to the recipient from the initiating external account.
    },
  ],
});

2. Switch chain

const provider = await connector.getProvider();
await provider.request({
  method: 'wallet_switchEthereumChain',
  params: [{ chainId: '0x61' }], // chainId must be in hexadecimal numbers
});

3. Sign a message

const provider = await connector.getProvider();
await provider.request({
  method: 'personal_sign',
  params: [address, 'test'],
});

const provider = await connector.getProvider();
await provider.request({
  method: 'eth_signTypedData_v4',
  params: [
    address,
    JSON.stringify({
      domain: {
        name: 'EPNS COMM V1',
        chainId: 80001,
        verifyingContract: '0xb3971BCef2D791bc4027BbfedFb47319A4AAaaAa',
      },
      primaryType: 'Data',
      types: {
        Data: [
          {
            name: 'data',
            type: 'string',
          },
        ],
        EIP712Domain: [
          {
            name: 'name',
            type: 'string',
          },
          {
            name: 'chainId',
            type: 'uint256',
          },
          {
            name: 'verifyingContract',
            type: 'address',
          },
        ],
      },
      message: {
        data: '2+{"notification":{"title":"Push Title Hello","body":"Good to see you bodies"},"data":{"acta":"","aimg":"","amsg":"Payload Push Title Hello Body","asub":"Payload Push Title Hello","type":"1"},"recipients":"eip155:5:0x6ed14ee482d3C4764C533f56B90360b767d21D5E"}',
      },
    }),
  ],
});

4. Call a smart contract function

import Web3 from 'web3';
const provider = await connector.getProvider();
// Create Web3 instance
const web3 = new Web3(provider); // use the provider from meteor.
const contract = new web3.eth.Contract(ABI, ADDRESS);
...
