Build with 1RPC

Replace the existing URL with 1RPC's endpoint to interact with the blockchain.

Curl

curl --request POST \
--url https://1rpc.io/eth \
--header 'Accept: application/json' \
--header 'Content-Type: application/json' \
--data '{ "id": 1, "jsonrpc": "2.0", "method": "eth_blockNumber" }'

Go

package main

import (
    "context"
    "fmt"
    "github.com/ethereum/go-ethereum/ethclient"
)

func main() {
    const url = "https://1rpc.io/eth"  // url string
    
    rpcClient,err := ethclient.Dial(url)
    
    if err != nil {
        panic(err)
    }
    
    blockNumber, err := rpcClient.BlockNumber(context.Background())
    
    if err != nil {
        panic(err)
    }
    
    fmt.Println(blockNumber)
}

Web3.js

const Web3 = require('web3');

const url = 'https://1rpc.io/eth'  // url string

const web3 = new Web3(new Web3.providers.HttpProvider(url));

web3.eth.getBlockNumber((error, blockNumber) => {
    if(!error) {
        console.log(blockNumber);
    } else {
        console.log(error);
    }
});

Python

from web3 import Web3
            
def test_block_number(self):
    url = 'https://1rpc.io/eth'  # url string
    
    web3 = Web3(HTTPProvider(url))
    print(web3.eth.block_number)

Websocket

$ wscat -c wss://1rpc.io/dot
