Building a product on Solana or Robinhood Chain data?
Skip the Geyser pipeline — embed KOL flow, deployer reputation, and the all-DEX firehose over REST, WebSocket, or webhooks. The Business tier (€400/mo) is the self-serve embed license at 500k calls/day — Enterprise adds white-label & redistribution.
Building a product on Solana or Robinhood Chain data?
MadeOnSol isn't an RPC or another generic token API — it's Solana & Robinhood Chain memecoin intelligence that's painful to build in-house, pulled from dual-region gRPC shred streams and our own Robinhood Chain node, pushed to your app as events land.
Signals you'd otherwise build
KOL & smart-money flow from 2,000+ labeled wallets, deployer reputation, coordination clusters, linked-wallet entity resolution, and an all-DEX firehose.
Cielo Finance takes a different angle. Instead of focusing on discovery or speed, it excels at organized, portfolio-level monitoring of wallet lists.
Strengths:
Real-time feed. Cielo provides a live, filterable transaction feed across all wallets you track. Every swap, transfer, and DeFi interaction shows up as it happens, organized by wallet and token.
Multi-chain support. Cielo covers Solana, Ethereum, Base, Arbitrum, BSC, and other chains in a unified feed. Not as many chains as Nansen, but enough for most traders.
Custom wallet lists. Create labeled lists of wallets (e.g., "KOL wallets," "Fund wallets," "Sniper bots") and monitor each list separately. This organizational layer is more developed than GMGN's bookmark-style tracking.
Telegram and Discord alerts. Cielo pushes wallet activity to Telegram bots and Discord channels, so you get notified without keeping a browser tab open.
Portfolio aggregation. Track your own wallets and positions alongside the wallets you monitor. See your P&L in context with the smart money you follow.
Weaknesses:
Discovery is limited. Cielo does not have a built-in smart money discovery engine. You need to find interesting wallets elsewhere (GMGN, Nansen, Twitter/X) and then import them into Cielo for monitoring.
Learning curve. The interface is powerful but dense. Setting up feeds, filters, and notification rules takes time to configure properly.
Pricing. Cielo currently publishes Free, Pro at $59/month, and Whale at $199/month (annual-plan pricing), with explicit Solana/EVM wallet-tracking limits.
No built-in trading. Cielo is observation-only. You see the trades; you execute elsewhere.
Best for: Traders who already have a wallet list and want organized, cross-platform monitoring with Telegram/Discord push notifications.

Smart money tracking is the practice of identifying wallets that consistently make profitable trades and then monitoring their activity in real time. On Solana, where memecoin launches happen every minute and the best entries come within the first few hours of a token's life, knowing what experienced traders are buying before the crowd catches on is a genuine edge.
Three platforms dominate this space for Solana traders: Nansen, GMGN, and Cielo. Each takes a fundamentally different approach to the same problem, and the right choice depends on whether you are an institutional researcher, a fast-moving memecoin trader, or a portfolio-level analyst.
What Smart Money Tracking Actually Means
The premise is straightforward: some wallets are better at trading than others. A wallet that bought five tokens in the last month and four of them did a 10x is interesting. A wallet that consistently enters tokens before major price moves, across hundreds of trades with a 60%+ win rate, is a signal worth following.
Smart money tracking tools solve three problems:
Discovery. Which wallets are consistently profitable? How do you find them?
Monitoring. What are those wallets doing right now? What did they just buy?
Signal extraction. When multiple smart wallets converge on the same token, that is a stronger signal than any single wallet's trade.
Each of the three platforms handles these differently.
Nansen is the oldest and most comprehensive on-chain analytics platform in the comparison. Founded in 2020, it built its reputation on Ethereum wallet labeling and has since expanded to 40+ chains including Solana.
Strengths:
Entity labeling. Nansen identifies and labels wallets belonging to funds, protocols, exchanges, team wallets, and known traders. This context is critical -- knowing that a wallet belongs to a venture fund versus a retail whale changes how you interpret its trades.
Cross-chain coverage. If you care about wallets that move between Ethereum, Solana, Base, Arbitrum, and other chains, Nansen is the only tool in this comparison that provides unified tracking across all of them.
Smart Money composite signals. Nansen aggregates across hundreds of labeled wallets to surface "Smart Money" composite indicators for tokens. When their Smart Money index shows accumulation on a specific token, it reflects the behavior of a large, diversified pool of tracked wallets.
NFT analytics. Deep NFT wallet tracking and market intelligence, relevant for Solana NFT traders.
Research dashboards. Pre-built dashboards for DeFi flows, exchange deposits/withdrawals, stablecoin movements, and token holder analysis.
Weaknesses:
Price. Nansen made its Solana analytics free in January 2026. Pro is now for broader multi-chain/premium functionality and currently sits around the $49–69/month range depending on billing/offer, rather than the old $150+ entry price.
Solana-specific depth. Nansen covers Solana, but its labeling is thinner on Solana-native wallets compared to Ethereum. Memecoin-specific wallets -- the snipers, the early pump.fun buyers, the copy-trade targets -- are less thoroughly categorized than EVM smart money.
Latency. Nansen is not built for real-time memecoin sniping. Data updates on their dashboards can lag by minutes, which is an eternity in Solana memecoin trading.
No free tier for analytics. There is a limited free exploration, but meaningful wallet tracking requires a paid subscription.
Best for: Fund managers, researchers, and traders who need cross-chain smart money intelligence with institutional-grade labeling. Not optimized for speed-sensitive Solana memecoin plays. If you settle on Nansen, our guide to using Nansen for Solana walks through its on-chain analytics and Smart Money labels in practice.
GMGN carved out its niche by focusing entirely on what Solana memecoin traders actually need: fast wallet discovery, real-time trade monitoring, and token-level wallet analysis. It is the most Solana-native tool in this comparison.
Strengths:
Free to use. The core wallet tracking, token pages, and smart money feeds are free. No subscription required for the features that matter most.
Speed. GMGN surfaces new trades and wallet activity within seconds. For memecoin trading where minutes matter, this speed advantage over Nansen is significant.
Memecoin-focused labels. GMGN labels wallets specifically relevant to memecoin trading: snipers, early buyers, high-win-rate traders, and known bot wallets. These categories are more useful for Solana memecoin trading than Nansen's institutional labels.
Token pages. Each token page shows top holders, early buyer performance, wallet inflow/outflow, and developer wallet activity. It is a self-contained research view for evaluating new launches.
Built-in trading. GMGN integrates a swap interface, so you can research and execute without leaving the platform.
Weaknesses:
Limited API. GMGN does not offer a public API for building custom tools or automating signal extraction. Everything is browser-based.
No advanced alerts. You cannot set up complex conditional alerts (e.g., "notify me when three or more tracked wallets buy the same token within 10 minutes"). Monitoring is manual or requires constant screen time.
Single-chain focus. Solana coverage is strong, but if you also trade on Ethereum or Base, you need a separate tool.
Community-sourced labels. Wallet labels are less rigorously verified than Nansen's. Some "smart money" labels reflect one good run rather than sustained performance.
Best for: Retail Solana memecoin traders who want fast, free wallet intelligence and do not need API access or cross-chain coverage.
Use Nansen if you manage serious capital, need cross-chain intelligence with verified entity labels, and are willing to pay for Nansen Pro when you need the broader premium/multi-chain layer for the most comprehensive dataset. Nansen is a research platform first, not a trading speed tool.
Use GMGN if you trade Solana memecoins and need fast, free smart wallet intelligence. GMGN is the best free option for discovering which wallets are winning and seeing what they are buying right now.
Use Cielo if you already have a curated list of wallets to monitor and want organized, multi-chain tracking with push notifications. Cielo is the best "monitoring layer" to run alongside your other tools.
Use all three if your workflow demands it. Many active traders use GMGN for discovery, Cielo for monitoring, and occasionally check Nansen for institutional-grade context on specific wallets or tokens.
The API-First Alternative
Dashboard tools show you what is happening. APIs let you build on top of what is happening. If you want to programmatically access KOL coordination signals, deployer intelligence, and copy-trade triggers -- data you can pipe into bots, alerts, and custom dashboards -- the MadeOnSol API covers a different surface than any of these three tools.
The MadeOnSol API tracks 1,058 curated KOL wallets with real-time trade feeds, deployer-hunter intelligence (creator wallet history, bonding patterns, rug indicators), and token velocity metrics. It is not a replacement for Nansen, GMGN, or Cielo -- it is the data layer for builders who want to automate what those dashboards show you manually.
The Bottom Line
There is no single best smart money tool. The right answer depends on your budget, your chain focus, and whether you need speed, depth, or programmability.
For most Solana memecoin traders starting out, GMGN is the obvious first step -- it is free and fast. As your wallet list grows and you want organized monitoring with notifications, add Cielo. If you trade across chains or need institutional-grade analytics, evaluate Nansen.
For a version of this comparison that swaps in Birdeye and Solscan instead of Nansen and GMGN, see Cielo vs Birdeye vs Solscan, which focuses specifically on Solana-native copy-trading workflows.
And if you want to build systems on top of smart money data rather than just look at dashboards, check the MadeOnSol API documentation for what is possible when wallet intelligence comes through an API.
This comparison had major pricing drift. Nansen made Solana analytics free in January 2026, including Smart Money, Token God Mode, Wallet Profiler and Solana PnL surfaces. Nansen Trading is also open to free users; its January announcement listed 0.25% trading fees for Free and 0.10% for Pro. Cielo currently supports 30+ chains with Free, Pro $59/month, and Whale $199/month plans. GMGN also spans Solana/EVM/Tron trading surfaces now.
