DEV Community: Chainsight

Building a Multi-Asset Dashboard: Crypto, Forex & Stocks in One API

Chainsight — Fri, 07 Aug 2026 08:00:59 +0000

The Fragmentation Problem

Most developers use 3+ APIs for financial data: CoinGecko for crypto, Alpha Vantage for forex, Yahoo Finance for stocks. Three rate limits, three billing accounts, three SDKs.

Current Market: Fear & Greed at 29/100 (Fear)

Bitcoin ($63,652.00) 📈 +1.3%
Ethereum ($1,862.26) 📉 -0.2%
Tether ($1.00) 📈 +0.0%
BNB ($590.04) 📈 +1.3%
USDC ($1.00) 📈 +0.0%

One API, All Assets

The ChainSight API unifies crypto, forex, stocks, and commodities:

curl "https://chainsight-api.onrender.com/v1/forex/overview"

{
  "forex": [
    {"symbol": "EUR/USD", "rate": 1.1435, "change_pct": 0.12},
    {"symbol": "GBP/USD", "rate": 1.3251, "change_pct": -0.08},
    {"symbol": "USD/JPY", "rate": 148.92, "change_pct": 0.31}
  ],
  "stocks": [
    {"symbol": "SPY", "price": 589.73, "change_pct": 0.45},
    {"symbol": "AAPL", "price": 214.29, "change_pct": 1.23},
    {"symbol": "NVDA", "price": 135.40, "change_pct": -0.67}
  ],
  "commodities": [
    {"symbol": "Gold", "price": 3341.60, "change_pct": 0.31},
    {"symbol": "Oil", "price": 80.75, "change_pct": -0.22}

How to Detect Honeypot Tokens Before You Buy — A Developer Guide

Chainsight — Tue, 04 Aug 2026 08:00:49 +0000

The $12B Problem

In 2024-2025, over $12 billion was lost to crypto scams. Honeypot tokens — contracts that let you buy but never sell — are among the most common traps.

Current Market: Fear & Greed at 25/100 (Extreme Fear)

Bitcoin ($63,652.00) 📈 +1.3%
Ethereum ($1,862.26) 📉 -0.2%
Tether ($1.00) 📈 +0.0%
BNB ($590.04) 📈 +1.3%
USDC ($1.00) 📈 +0.0%

What Is a Honeypot?

A honeypot token has hidden sell restrictions:

Sell taxes of 99%+
Blacklist functions
Owner-only trading
Upgradeable proxy contracts

Detecting Honeypots with Code

import httpx

API = "https://chainsight-api.onrender.com"

async def check_token(address: str):
    resp = httpx.get(f"{API}/v1/security/honeypot/{address}")
    data = resp.json()

    if data.get("is_honeypot"):
        print("🚨 HONEYPOT DETECTED — Do not buy!")
        return False

    risk = data.get("risk_level", "unknown")
    sell_tax = data.get("sell_tax", 0)

    if risk == "high" or sell_tax > 10:
        print(f"⚠️ High risk — Sell tax: {sell_tax}%")
        return False

    print(f"✅ Looks safe — Risk: {risk}")
    return True

Batch Check Multiple Tokens

addresses = ["0xtoken1", "0xtoken2", "0xtoken3"]

resp = httpx.post(f"{API}/v1/security/batch-check",
    json={"addresses": addresses})

for result in resp.json().get("results", []):
    status = "🚨" if result.get("is_honeypot") else "✅"
    print(f"{status} {result['address'][:10]}...")

Red Flags Before You Buy

Sell tax > 10% — Likely honeypot
Hidden owner — Contract modifiable post-deployment
No liquidity lock — Team can drain funds
Copy-paste contract — Same code as known scams

Full Token Security Audit

curl "https://chainsight-api.onrender.com/v1/security/token/0xdAC17F958D2ee523a2206206994597C13D831ec7"

Returns: honeypot status, buy/sell tax, owner privileges, contract verification, and risk score.

How to Track Crypto Whale Transactions Across 9 Blockchains with Python

Chainsight — Sat, 01 Aug 2026 08:00:57 +0000

Why Whale Tracking Matters

When a whale moves $50M of ETH, the market notices. Learning to detect these movements before the price reacts gives you an edge.

Current Market: Fear & Greed Index at 27/100 (Fear)

Bitcoin ($62,987.02) 📉 -1.2%
Ethereum ($1,867.80) 📉 -1.1%
Tether ($1.00) 📈 +0.0%
BNB ($589.52) 📉 -0.4%
USDC ($1.00) 📈 +0.0%

What the API Provides

The ChainSight API tracks whale transactions across 9 blockchains:

Chain	Source	Min Trackable
Ethereum	Etherscan V2	100 ETH
Bitcoin	Blockstream Mempool	1 BTC
BSC	Etherscan V2	1000 BNB
Polygon	Etherscan V2	10000 MATIC
Arbitrum, Base, OP, Avalanche	Etherscan V2	Varies
Solana	Solscan API	100 SOL

Quick Start

import httpx

API = "https://chainsight-api.onrender.com"

# Get large ETH transactions
resp = httpx.get(f"{API}/v1/whales/chain/ethereum", params={"min_value": 100000})
for tx in resp.json():
    if "hash" in tx:
        print(f"🐋 {tx['value']} ETH — {tx['from_address'][:12]}...")

Build a Whale Alert Bot

import httpx, asyncio

API = "https://chainsight-api.onrender.com"

async def monitor():
    last_hash = ""
    while True:
        resp = httpx.get(f"{API}/v1/whales/chain/ethereum?min_value=500000")
        txs = resp.json()
        for tx in txs:
            if tx.get("hash") and tx["hash"] != last_hash:
                print(f"🚨 WHALE: {tx['value']} ETH moved!")
                last_hash = tx["hash"]
        await asyncio.sleep(60)

asyncio.run(monitor())
