ZachXBT is the most famous onchain detective in crypto. His real identity is unknown. His Twitter account, which passed half a million followers by 2024, is a steady stream of investigations into rug pulls, influencer scams, stolen funds, and suspicious wallet activity. He operates entirely through public blockchain data, open-source tools, and dogged persistence. He does not charge for investigations of stolen assets, though he accepts tips and occasionally works on paid retainers for major platforms.

Zach’s breakthrough moment came in 2021 when his investigations into a series of NFT scams started producing results. Influencers he exposed lost sponsorships. Stolen funds he traced were partially recovered. Platforms he flagged took down suspicious listings. By 2022 he had become a de facto one-person police force for crypto scams, and affected victims started DMing him directly for help. He couldn’t respond to most of them but took on high-impact cases that could set precedent or recover meaningful amounts.

His methodology is worth studying. Zach starts with a known bad transaction, then follows the funds wallet by wallet, labeling each as CEX deposits, bridge transfers, or further mixing. He checks for known patterns: consolidation to a single wallet, use of Tornado Cash or Railgun, bridge hops to chains with less tracking. He cross-references against social media timelines to tie wallets to real humans. And he publishes everything publicly, with screenshots and transaction links, so other investigators can verify his work.

The broader impact of ZachXBT is that he proved a single motivated individual with public tools could substantially improve crypto security. He’s forced platforms to respond faster, made influencer scams more costly, and created accountability in a space that traditional law enforcement still struggles to police. His legacy is that the next generation of crypto scammers has to work much harder to avoid getting caught — because Zach, or someone like him, is probably already watching the wallets.

Cielo Finance launched in 2023 as a wallet-alert service. The idea was simple: follow specific addresses and get instant notifications whenever they make a transaction. Telegram alerts, Discord integrations, and a clean web dashboard. Traders who had been manually refreshing block explorers to monitor smart wallets suddenly had a push notification system that could keep them ahead of the market.

Cielo’s sweet spot was copy trading without copying. Serious memecoin traders didn’t necessarily want to auto-execute trades based on a target wallet — they wanted to be alerted and make their own decision. Cielo provided the alerting layer. Users could follow hundreds of wallets at once, filter by transaction size or token type, and get notifications within seconds of onchain confirmation. For the active trader, this was a substantial edge over refreshing DEX Screener manually.

By 2024 Cielo had integrated multi-chain support, advanced filtering, and premium tiers for serious users. Its free tier kept most features accessible, which helped adoption spread rapidly through Crypto Twitter. At one point, Cielo alerts were the single most-referenced “how did you know” answer in screenshots of successful memecoin trades — people would post profit and tag Cielo as the source of the entry signal.

What Cielo demonstrates is that alerting infrastructure is its own product category. Data platforms like Nansen and Arkham let users explore wallet activity on demand. Cielo inverted that: instead of pulling data when you remember to check, the data finds you. For active traders, that push model was transformative. It turned smart-money tracking from a periodic research task into a real-time feed that could drive trading decisions throughout the day, in the same way stock traders use Bloomberg alerts. The alert was often more valuable than the dashboard.

DEXTools launched in 2020, making it one of the earliest DEX analytics platforms — predating DEX Screener, Birdeye, and most of today’s dominant tools. In the pre-Solana era, DEXTools was the default chart for every Ethereum token traded on Uniswap or Sushiswap. The interface was clunky and the performance was occasionally slow, but there was no real competition.

The DEXTools business model included a native token (DEXT) with utility features: token listings, premium tiers, and community promotions. For a time in 2021, getting onto the DEXTools “hot pairs” page was a significant catalyst for any new token — visible to tens of thousands of active users and a frequent entry point for degen traders discovering new plays.

Then DEX Screener happened. Launched around the same time but with faster performance, better multi-chain support, and a cleaner interface, DEX Screener steadily ate into DEXTools’ market share. By 2023 DEX Screener had overtaken DEXTools as the default DEX analytics platform, and DEXTools was left as a legacy tool with a dedicated but shrinking user base. The DEXT token never recovered to its bull-market highs.

DEXTools is worth remembering because it represents the first generation of DEX analytics — the tools that existed before the category fully matured. Being first isn’t always enough. DEX Screener out-executed DEXTools on performance, UX, and multi-chain coverage, and won despite launching into a market DEXTools had helped create. It’s a textbook lesson in how market leadership in crypto tooling can shift rapidly when a new entrant actually cares about the boring details the incumbent took for granted. DEXTools is still around, still useful, but no longer the default anywhere.

GeckoTerminal launched in 2023 as CoinGecko’s answer to DEX Screener. CoinGecko had dominated the centralized exchange market data space for years but had limited presence in DEX-specific analytics. GeckoTerminal was the response: a dedicated platform for tracking prices, pools, and volumes across decentralized exchanges on every major chain. The branding leveraged CoinGecko’s established trust with millions of users.

The product was solid from launch. Multi-chain coverage, clean charts, pool-level analytics, and direct integration with CoinGecko’s broader data backend gave it credibility and breadth that smaller competitors couldn’t match overnight. For CoinGecko, it was a defensive move — protecting their position in the market data category as DEX trading volume started to rival CEX volume for the first time in history.

GeckoTerminal’s strategic value came from CoinGecko’s existing relationships with every major crypto project. When a new token launched, CoinGecko listings were already part of the standard marketing checklist. GeckoTerminal piggybacked on that: the same submission process could now include DEX pool data, bringing trending tokens into GeckoTerminal automatically. The platform grew rapidly without needing to fight for attention the way independent tools did.

The deeper lesson of GeckoTerminal is about distribution advantages in crypto. DEX Screener, Birdeye, and similar tools had to earn every user manually through Twitter virality and word of mouth. CoinGecko started with tens of millions of existing users and a trusted brand, so GeckoTerminal reached critical mass in months instead of years. Sometimes the best way to enter a category is to already own the adjacent one. Incumbents can be displaced in crypto — as DEXTools learned — but not by competitors without distribution moats of their own.

DeBank launched around 2020 as a simple multi-chain wallet tracker for DeFi users on Ethereum. Its pitch was simple: enter any wallet address and see all DeFi positions across every major protocol, normalized into a clean interface. No signup required. No tracking. Free. The utility was obvious and the product spread organically through Crypto Twitter.

The turning point for DeBank was the bear market of 2022. While other analytics platforms were struggling with falling revenue, DeBank focused on what it did well and kept expanding coverage. By 2024 it supported more than 50 chains and hundreds of DeFi protocols. Its “Web3 ID” social layer — which let users link wallets to profiles and follow each other’s activity — made it a hybrid between analytics platform and social network for onchain-native users.

DeBank’s dominance comes from solving a genuinely hard problem: aggregating DeFi positions across chains in a way that’s actually accurate. Each protocol exposes data differently, each chain has different conventions, and parsing liquidity positions, lending collateral, staking rewards, and vault deposits into a single unified view requires real engineering. DeBank invested in that infrastructure when competitors cut corners, and the quality gap became a moat.

The company raised funding, launched its own token (DEBANK), and occasionally teased deeper product plans including a wallet and a DeFi hub. But the core free product has remained DeBank’s primary value proposition. For tens of millions of DeFi users across Crypto Twitter, DeBank is simply the answer to “show me what this wallet owns.” It’s one of the rare crypto products that everyone uses and almost nobody pays for — and it survives because the engineering moat is deep enough to keep competitors away.

Zapper and Zerion launched within months of each other in 2020, both targeting the same problem: give DeFi users a single dashboard to see every position across every protocol. The products looked nearly identical at launch. Both had slick UIs. Both listed the same protocols. For several years, they were locked in a tight competition to be “the” DeFi portfolio app, each raising millions from top VCs and competing for the same user base.

Zapper, based in Montreal, pushed deeper into transaction features — letting users execute trades and DeFi actions directly inside the interface. Zerion, based in Berlin, focused more on analytics and later built a full-featured mobile wallet. Both companies expanded to multiple chains: Ethereum, Polygon, Arbitrum, Optimism, Base, Solana. Both launched NFT portfolio tracking when NFTs were hot. Both added social features when Farcaster became interesting.

Over time, DeBank ate into both products by offering a more comprehensive (and free) analytics view, while Rabby and Rainbow competed for the mobile wallet use case. Zapper and Zerion ended up in an awkward middle: too fancy to be pure portfolio trackers, not specialized enough to win any specific category. Both survived and remain useful, but neither became the default destination for DeFi users the way Uniswap did for swaps.

The Zapper vs Zerion story is a useful lesson in crypto product strategy. Launching with an identical competitor means you’re locked in a race where neither side can differentiate on features alone. Eventually you have to pick a wedge — transactions, social, mobile-first, wallet, analytics — and commit. Both companies arguably took too long to pick, and by the time they did, the category had fragmented into specialists who were better at each slice. The portfolio dashboard market turned out not to have room for two generalists.

Bubblemaps launched in 2022 with a single simple idea: show wallet concentration as a visual graph instead of a table. Each top holder becomes a circle sized by their balance, and connected wallets — ones that funded each other or moved tokens between themselves — are linked by lines. In two seconds, a user could see whether a token’s supply was genuinely distributed or whether it was concentrated in a small cluster of related wallets pretending to be independent.

The visual format was the product. Raw concentration numbers (like “top 10 holders own 35%”) had existed before. But humans are pattern-matching machines, and a picture of a wallet graph communicates concentration instantly in a way numbers don’t. Bubblemaps turned a minute of manual analysis into a one-second glance, which meant traders actually did the analysis instead of skipping it.

By 2024 Bubblemaps had become a standard due-diligence step for Solana memecoin traders. Before aping into a new token, serious traders would pull up its Bubblemap to check if the top holders were clustered. The BMT token launched in mid-2024 via airdrop, rewarding users of the free tool, and established Bubblemaps as one of the few analytics products with a real token-aligned community.

Bubblemaps’ lesson is that visualization matters as much as data. Tools like Arkham and Nansen exposed the same underlying wallet relationships, but as tables and graphs with learning curves. Bubblemaps made the single most important signal — cluster concentration — legible at a glance. In a category where the difference between rug and real is often a wallet map, that speed advantage was enough to build a business on. Sometimes the best product is the one that shows the obvious thing most clearly.

Solscan launched in 2021 as a clean, fast block explorer for Solana — the Solana equivalent of Etherscan. The team, based in Vietnam, prioritized performance and UX over fancy features. While competitors tried to bundle analytics and social features, Solscan focused on the core job: show a transaction, show a wallet, show a token, and do it faster than anyone else. That discipline won the category.

By 2022 Solscan was the default explorer referenced in Solana documentation, protocol frontends, wallet error messages, and almost every tutorial. If a Solana dev wanted to link a user to a transaction, they linked to Solscan. If a wallet wanted to show a transaction history, it embedded Solscan data. Etherscan had never had perfect dominance on Ethereum because of competitors like Etherchain and Blockscout — but Solscan became Solana’s version of Etherscan in a way that competitors couldn’t dislodge.

In 2024 Solscan was acquired by Etherscan’s parent company, consolidating the two dominant block explorers in crypto under one roof. The deal was noteworthy because it was a rare case of a major infrastructure consolidation happening without drama. Both teams kept operating. Both brands remained intact. The back-end integration made it easier for cross-chain workflows, but users barely noticed the change.

Solscan’s lesson for other infrastructure projects is focus. The explorer category is unglamorous — nobody writes Twitter threads about their favorite block explorer — but it’s essential plumbing, and winning it requires relentless attention to latency, data accuracy, and UX details that most teams consider boring. Solscan won because it treated those boring things as the whole product, not as a distraction from some more ambitious roadmap. Sometimes the best strategy is just to build the basic thing better than anyone else can.

Etherscan launched in 2015, shortly after Ethereum’s mainnet. Founded by Matthew Tan, a Malaysian developer working solo in his spare time, it was initially just a side project — a way to browse the new Ethereum blockchain with a nicer interface than the default tools. Within a year it was the default block explorer for the entire Ethereum ecosystem. Ten years later, it still is.

Etherscan’s dominance is so complete that “Etherscan” has become a verb among crypto natives. “Etherscan it” means look up the transaction, check the contract, verify the source code. The platform supports contract verification (users can submit source code and prove it matches deployed bytecode), transaction decoding, token tracking, gas tracking, and dozens of other features that became load-bearing infrastructure for the entire ecosystem. Nearly every Ethereum tutorial links to Etherscan. Every protocol uses Etherscan links in its frontend.

What makes Etherscan remarkable is how deliberately unglamorous it has stayed. No flashy marketing. Relatively infrequent UI changes. A focus on free-tier reliability that has kept the site usable through every major Ethereum traffic spike from DeFi summer to NFT mania to the 2024 meme season. The premium API tier has quietly generated significant revenue, enough to fund the expansion into sister explorers for BSC (BSCScan), Polygon (Polygonscan), Arbitrum (Arbiscan), Optimism (Optimistic Etherscan), and Base (BaseScan) — all using the same core product and brand.

Etherscan’s long-term importance is that it’s the closest thing crypto has to a neutral public utility for blockchain data. Every major piece of crypto journalism, every forensic investigation, every user troubleshooting a failed transaction, every auditor, every developer — everyone ends up on Etherscan eventually. Matthew Tan never sought celebrity status or raised from VCs until recently. He just built infrastructure, kept it running, and let the network effects compound for a decade. The result is one of the most important, quiet, load-bearing pieces of crypto infrastructure in existence.

Arkham Intelligence launched in 2022 with a mission that was both useful and uncomfortable: dox the whales. The platform scraped public blockchain data, combined it with off-chain intelligence, and matched anonymous wallets to real-world entities — exchanges, VCs, treasuries, notable individuals. Users could type “Alameda Research” and see live balances across dozens of wallets. For the first time, the financial lives of crypto’s biggest players were searchable.

Arkham’s controversial move came in July 2023 with the launch of its “Intel Exchange” — a bounty marketplace where users could post rewards for identifying specific anonymous wallets. Crypto Twitter exploded. Critics called it a surveillance economy that would enable stalking and targeted attacks on private holders. Supporters argued it was just making public data more legible. Both sides had a point.

The ARKM token launched on Binance in July 2023 via a Launchpad, raising significant capital and opening at a premium. Despite the controversy, Arkham became a standard tool for crypto journalists, forensic investigators, compliance teams, and professional traders. Its labeled-address database grew into the most comprehensive of its kind, and its dashboard visualizations of treasury movements (especially during stress events) became must-read crypto content.

Arkham’s broader impact is that it forced the crypto industry to confront the gap between “public blockchain” and “private identity.” Every onchain transaction has always been public. Arkham just made them easy to connect to humans. Whether that’s progress toward transparency or an erosion of financial privacy depends on whether you’re a whale or a whale-watcher. Either way, the world where anonymous wallets stayed anonymous is over. Arkham made sure of it.
