The Proxy Combo Used by Web3 Builders and DAOs

Alright, mates, let’s sling on the boots and wade straight into the nitty-gritty of proxies in the wild world of Web3. Whether you’re spinning up a DAO or wrangling the latest dApp, using the right proxy combo can mean the difference between a smooth ride and a flat tyre. Below, I’ll break down the essential proxy combos, why they matter, how to set them up, and where to snag reliable proxies (hint: ProxyRoller is your best mate here).

Why Proxies Are the Secret Sauce for Web3 Ops

Web3’s all about decentralisation, but ironically, a stack of builders and DAOs still need to route their network traffic through proxies—for privacy, scaling, botting, or just getting around pesky geo-blocks. Think of proxies as your digital surfboard, letting you ride the gnarly waves of the internet without wiping out.

Types of Proxies: Quick Comparison

Proxy Type	Use Case	Anonymity Level	Speed	Price
HTTP	API access, web scraping	Low-Med	Fast	Free/Cheap
SOCKS5	General, blockchain RPCs	High	Fast	Varies
Residential	Avoid bans, real IPs	Very High	Slower	Expensive
Datacenter	Fast, scalable, less stealth	Medium	Very Fast	Cheap
Rotating	Scraping, airdrop farming	High	Medium	Varies

The Proxy Combo: The Web3 Builder’s Power Stack

Here’s the proxy cocktail that’s become the go-to for Web3 projects:

1. SOCKS5 Proxy – For privacy and versatility.
2. Rotating HTTP/HTTPS Proxies – For scraping or high-volume API calls.
3. Residential IPs – For dodging anti-bot filters, particularly when interacting with KYC-heavy or region-locked endpoints.

Why This Combo?

• SOCKS5 is protocol-agnostic. Works like a charm for Ethereum JSON-RPC, IPFS, or just about any TCP stream.
• Rotating HTTP/HTTPS keeps the heat off your main IP when scraping or automating interactions.
• Residential IPs blend you into the crowd, making it tough for rate limiters or anti-bot systems to pick you out.

Dead-Simple Setup With ProxyRoller

ProxyRoller (https://proxyroller.com) is the go-to for free proxies, no strings attached. Here’s how you get rolling:

Step 1: Fetching Proxies from ProxyRoller

1. Head to https://proxyroller.com.
2. Pick your poison (SOCKS5, HTTP, or HTTPS).
3. Copy a list of fresh proxies—no signup, no faff.

Example:

# Grab a SOCKS5 proxy list (replace with updated URL from ProxyRoller)
curl https://proxyroller.com/api/proxies/socks5

Step 2: Using Proxies with Your Node App

Suppose you’re building a bot to interact with an Ethereum node—say, Infura or Alchemy. Here’s how to pass traffic through a SOCKS5 proxy using web3.js and the socks-proxy-agent package.

const Web3 = require('web3');
const { SocksProxyAgent } = require('socks-proxy-agent');

// Replace with your proxy from ProxyRoller
const proxy = 'socks5://123.45.67.89:1080';
const agent = new SocksProxyAgent(proxy);

const web3 = new Web3(new Web3.providers.HttpProvider('https://mainnet.infura.io/v3/YOUR_API_KEY', {
  agent
}));

web3.eth.getBlockNumber().then(console.log);

Step 3: Rotating Proxies in Python

Let’s say you’re scraping NFT metadata or airdrop lists. Here’s a snappy way in Python to rotate HTTP proxies from ProxyRoller:

import requests
import random

# Fetch proxies (update URL as needed)
proxy_list = requests.get('https://proxyroller.com/api/proxies/http').text.split('\n')
proxy_list = [p.strip() for p in proxy_list if p.strip()]

def get_proxy():
    return random.choice(proxy_list)

def fetch_url(url):
    proxy = get_proxy()
    proxies = {
        "http": f"http://{proxy}",
        "https": f"http://{proxy}",
    }
    response = requests.get(url, proxies=proxies, timeout=10)
    return response

data = fetch_url('https://api.opensea.io/api/v1/assets')
print(data.json())

Practical DAO Use Cases

• Airdrop Farming:
  Rotate proxies to farm airdrop eligibility without triggering anti-bot measures. Use residential proxies for the riskiest targets.
• Snapshot Voting:
  Run bots through SOCKS5 proxies to automate off-chain voting, keeping DAO ops stealthy and distributed.
• Governance Data Scraping:
  Aggregate proposals, votes, and sentiment from dozens of protocols, rotating HTTP proxies to avoid bans.

Gotchas and Best Practices

• Proxy Rotation:
  Don’t flog the same IP—rotate every few requests. Especially true for scraping or mass transactions.
• Health Checks:
  Proxies from free lists can be crook. Always check if a proxy is alive before using it.
• Rate Limiting:
  Even with proxies, APIs can throttle you. Respect rate limits or you’ll get the banhammer.
• Security:
  Avoid sending sensitive keys or credentials through public proxies. Use them for public data, not wallet management.
