On-chain

On-chain refers to any transaction or data point that is recorded directly on the blockchain, ensuring transparency, immutability, and public verifiability. From on-chain identity (DID) to verifiable provenance of assets, the "everything on-chain" movement is the core of Web3’s trustless architecture. In 2026, sophisticated on-chain analytics tools allow users to audit protocol reserves and track capital flows in real-time. This tag focuses on the value of transparency, block explorer utility, and the distinction between on-chain execution and off-chain scaling.

Chainlink Made a Historic Partnership with Mastercard to Let 3B+ Cardholders Buy Crypto On-chain

Chainlink Made a Historic Partnership with Mastercard to Let 3B+ Cardholders Buy Crypto On-chain

Chainlink has announced a partnership with Mastercard that allows over 3 billion cardholders worldwide to purchase crypto directly on-chain through a secure fiat-to-crypto conversion system. The collaboration leverages Chainlink’s interoperability infrastructure and Mastercard’s global payments network to power the new Swapper Finance platform. It addresses a key barrier that has prevented mainstream users from accessing on-chain economies by eliminating the complex multi-step processes traditionally required to convert fiat currency into cryptocurrency. We’re excited to announce that Chainlink and @Mastercard have partnered to enable billions of cardholders to purchase crypto directly onchain. https://t.co/1pKz03jQ7t Chainlink verifies and synchronizes key… pic.twitter.com/5jfLAAYn4D — Chainlink (@chainlink) June 24, 2025 “This is the type of traditional finance and decentralized finance convergence that Chainlink was built to make possible,” said Sergey Nazarov, co-founder of Chainlink, in the official announcement . Cardholders can now seamlessly convert fiat currency into crypto assets as easily as they would with any other purchase, directly accessing the on-chain economy without the hassle of setting up a wallet or registering with an exchange. Multi-Partner Ecosystem Powers Seamless Integration Behind this seamless experience lies a robust web of collaborators ensuring everything works flawlessly in the background. The Swapper Finance platform operates through a sophisticated ecosystem involving multiple technology partners collaborating to deliver a seamless user experience. ZeroHash provides the core compliance, custody, and transaction infrastructure, facilitating the conversion of regulated fiat currency into cryptocurrency for smart contract consumption. Shift4 Payments handles seamless card processing, while XSwap sources liquidity from decentralized exchanges, including the Uniswap protocol, to execute the final on-chain swaps. “ We are excited to be the infrastructure partner alongside Chainlink and Mastercard on the Swapper Finance platform ,” said Edward Woodford, CEO & co-founder of ZeroHash. As for Chainlink, the integration uses its verification system to synchronize key transaction details, ensuring secure connections between traditional payment methods and decentralized finance protocols. 💳 @Mastercard has reported that 30% of its transactions in 2024 were tokenized, recognizing stablecoins ability to disrupt financial services. #Mastercard #Tokenization https://t.co/rEFnCGmIao — Cryptonews.com (@cryptonews) February 13, 2025 This development arrives at an opportune moment when institutional adoption of blockchain technology is accelerating. In fact, Mastercard previously reported that 30% of its transactions in 2024 were tokenized . The partnership builds on this momentum by providing practical utility for digital assets beyond speculative trading, opening the door to mainstream adoption. Industry Giants Race to Capture the Crypto Payments Expansion While Chainlink and Mastercard’s partnership represents a major milestone; it’s part of a broader competitive struggle where payment giants are rapidly expanding their crypto capabilities. @visa and @yellowcard_app have partnered to expand stablecoin-powered payments across Africa. #stablecoin #Visa https://t.co/nB85xKKAXa — Cryptonews.com (@cryptonews) June 19, 2025 Visa recently partnered with Yellow Card Financial to bring stablecoin-powered payments to 20 African nations, demonstrating how traditional payment networks view crypto as essential infrastructure for emerging markets. Mastercard has also been particularly aggressive in building its crypto ecosystem, having launched over 100 crypto card programs globally and developing solutions like Crypto Credential for simplified transactions in the UAE and Kazakhstan . We’re beginning to witness a competitive dynamic that contrasts sharply with the payment industry’s more cautious approach during crypto’s early years, when Visa and Mastercard temporarily halted new crypto partnerships in 2023 following high-profile industry failures. 📊 @chainlink targets $260 trillion untokenized assets market through CCIP partnerships with top players as technical analysis shows descending triangle breakout potential toward $26-$30 targets. #Chainlink #Link https://t.co/NnPbSuLOOX — Cryptonews.com (@cryptonews) June 19, 2025 With these new developments, we could be gearing toward a maturation phase in which crypto utility is beginning to match its speculative appeal. This will potentially unlock the massive untokenized assets market that Chainlink has recently identified as a $260 trillion opportunity . Chainlink’s co-founder, Sergey Nazarov, sees this as a turning point that will finally connect three billion Mastercard users with on-chain trading environments globally.

“80% of Crypto Scams Could Be Stopped by One Mental Shift” — Crystal CEO | Interview

“80% of Crypto Scams Could Be Stopped by One Mental Shift” — Crystal CEO | Interview

The crypto industry’s rapid growth has created massive opportunities for innovation and a fertile ground for crypto scams . The scale of this exploitation became starkly apparent in 2024, when Americans alone lost a record $9.3 billion to crypto-related crimes , representing a devastating 66% increase from the previous year’s $5.6 billion. The FBI’s Internet Crime Complaint Center received nearly 150,000 crypto-related complaints in 2024, indicating that what once seemed like isolated incidents has now metastasized into a systematic threat to digital finance. Source: Chainalysis Perhaps most alarming is the demographic targeting, with people over 60 reporting the highest losses at $2.8 billion . At the same time, Chainalysis data suggests that North Korean hackers alone stole $1.34 billion from crypto platforms in 2024, representing 61% of all stolen funds. Crystal, a leading blockchain analytics platform, sits at the frontline of this battle. The company’s tools help track illicit cryptocurrency flows and provide crucial intelligence for investigations. We spoke with Navin Gupta, CEO of Crystal since early 2024, about the sophisticated manipulation tactics driving modern crypto fraud. With over 23 years of leadership experience across fintech giants including Citigroup, HSBC, and Ripple, Gupta brings a unique perspective on how traditional financial crime prevention applies to the decentralized world of cryptocurrency. Our conversation reveals how scammers exploit fundamental human psychology, why technical solutions alone aren’t enough, and what individuals and businesses can do to protect themselves. The Psychology Behind Crypto Manipulation CN: From your experience, what are the most common psychological tactics scammers use to build trust with their victims? Gupta: The most common tactics revolve around urgency, authority and familiarity. Scammers impersonate figures of perceived authority, such as project founders, influencers, or even support staff, to create an illusion of legitimacy. They exploit FOMO by creating time pressure “You’ll miss your chance if you don’t act now.” They also mimic the visual identity of real platforms, tapping into a victim’s trust in brands. These attacks are carefully orchestrated campaigns that understand human psychology at a deep level. What makes crypto particularly vulnerable is that many users are already operating in a high-risk, high-reward mindset, making them more susceptible to urgency-based manipulation. CN: How do scammers exploit personal relationships or social closeness – the so-called “trust trap” in modern crypto fraud schemes? Gupta: We’ve seen a surge in what we call “social infiltration.” Attackers slowly embed themselves into communities Discord servers, Telegram groups, even private DMs, posing as helpful members. They build rapport over time, sometimes for weeks, before proposing a scam investment or fake tool. The trap works because it doesn’t feel like fraud. It feels like a friend giving advice. The victim’s guard is down because of emotional familiarity. This is particularly insidious because it exploits one of crypto’s greatest strengths: community . These tight-knit communities built around shared interests and investment strategies become perfect hunting grounds for patient predators. Source: Chainalysis Recent Chainalysis data shows that “pig butchering” scams , which rely heavily on building fake relationships, have seen an 85-fold increase since 2020 . Victims often lose between $2-4 million individually, precisely because the emotional manipulation makes them willing to transfer larger amounts over time. The psychology is devastatingly effective because it taps into fundamental human needs for belonging and trust. When someone who has been helpful and friendly for weeks suddenly presents an “exclusive opportunity,” victims might evaluate the investment and try to maintain a relationship they value. Evolution of Social Engineering Tactics CN: Social engineering is evolving fast. What new behaviors or emotional triggers are attackers using in 2024–2025 that we didn’t see five years ago? Gupta: In 2024–2025, we’re seeing more hyper-personalized attacks. Thanks to leaked data and AI-powered profiling, scammers tailor messages that reflect the victim’s language, portfolio history, or even past interactions. Another trigger that has grown is empathy. Scammers fake medical emergencies or family-related causes to solicit crypto under emotional pretenses. There’s also a rise in “VIP scams” — attackers pretending to offer exclusive investment opportunities, exploiting status-driven FOMO. AI has been a massively destructive tool for scammers. They can now generate convincing personas, mimic writing styles, and even create deepfake videos of trusted figures. Just a few years ago, the level of personalization we’re seeing would have required teams of social engineers; now, it can be automated. Chainalysis research indicates that AI is making fraud “more scalable and affordable for bad actors to conduct,” which explains why we’re seeing such dramatic increases in both sophistication and volume. This hybrid approach has contributed to investment fraud becoming the costliest category, accounting for $5.7 billion in losses in 2024 alone, a 24% increase from the previous year. CN: Could you walk us through a case where the victim was manipulated using privileged or sensitive personal data? How do attackers usually get hold of such data? Gupta: In one case, Crystal analyzed, a victim received a phishing email that included a reference to a private wallet address and transaction from three years ago. The scammers had scraped blockchain data and cross-referenced it with leaked emails from old exchange breaches. This made the phishing message look highly legitimate. They even used the victim’s city and device type in the email footer. Data like this is often bought on darknet forums or extracted via malware and SIM-swaps. What’s particularly concerning is how the transparency of blockchain data, which is generally a feature, becomes a vulnerability when combined with traditional data breaches. Scammers can build incredibly detailed profiles by connecting on-chain activity with off-chain personal information. High-Stakes Social Engineering CN: Could you share a case Crystal worked on that holds a strong lesson about how social manipulation works in scams? Gupta: We investigated a case where a mid-sized crypto fund’s top manager was tricked by someone posing as their CEO on Telegram. The attacker spoofed the CEO’s Telegram ID, mimicked writing style, and asked for an “urgent liquidity transfer.” What’s shocking is that the attacker waited until the real CEO was traveling — information likely taken from social media. It’s a clear example of how scammers blend social engineering with timing and reconnaissance. The breach was emotional and contextual. This particularly shows why traditional corporate security training often fails in the crypto space. The speed and irreversibility of crypto transactions don’t allow for the usual verification processes that might catch such attacks in traditional finance. CN: Have you noticed an increase in scams targeting high-net-worth individuals or companies through tailored, “luxury” phishing attempts? If yes, how do these differ from mass-market scams? Gupta: Absolutely. High-net-worth targets are approached with sophistication. These phishing attempts often arrive via LinkedIn, private invite-only communities, or even through introductions from compromised contacts. The language is polished, the visuals mimic premium branding, and the attackers often reference private investment rounds or bespoke DeFi tools. The difference lies in the prep work. Mass-market scams are fast and generic — contrary, “luxury” scams are slow, curated, and often involve weeks of social engineering. Attackers invest months in building relationships with high-value targets. They’ll attend virtual events, contribute to discussions, and establish credibility before making their move. The ROI justifies this level of effort when a single successful attack can net millions. This trend is part of broader market data showing that people aged 50-59 lost $164 million in Q1 2025 alone to investment scams, despite representing a smaller victim pool than younger demographics. The sophistication extends beyond the approach, as these attackers often compromise legitimate contacts within a target’s network first and then use those trusted relationships as entry points. The patience and resources required suggest these aren’t individual bad actors, but organized operations with substantial backing. Technical Vulnerabilities and Human Error CN: What are some of the less obvious but dangerous mistakes individuals or businesses make that put their funds at risk? Gupta: One major issue is excessive platform trust. People assume that because a dApp looks slick or a Telegram bot has thousands of users, it must be safe. Another is poor key compartmentalization. Teams often store keys in shared environments like cloud folders or message threads. Businesses also overlook decentralized approval flows: if one person can sign large transactions, you’re just one social hack away from a breach. The decentralized nature of crypto means there’s no customer service department to call when things go wrong. This finality demands a completely different security mindset than traditional finance, but many users haven’t adapted their behaviors accordingly. CN: SIM-swap attacks remain a terrifyingly effective method. Can you break down how a SIM-swap can lead to a full asset drain? Gupta: In a SIM-swap, attackers convince a telecom provider to transfer your number to a SIM they control. From there, they intercept 2FA codes, reset email passwords, and gain access to exchange accounts. Within minutes, they can drain wallets, liquidate NFTs, or even use saved cards to steal fiat. To protect against this, one should use hardware security keys, avoid SMS-based 2FA, and set up a separate device/email for financial operations that isn’t tied to public contact points. The speed of a SIM-swap attack is what makes it so devastating in crypto. Unlike traditional finance, where there might be fraud detection systems or transaction delays, crypto moves at the speed of the blockchain, usually within minutes or even seconds. Building Scam-Resistant Behaviors CN: When looking at crypto scam victims, what’s more often the root cause: technical gaps or human error? Gupta: It’s usually human error that opens the door and technical gaps widen it. Think of it as a chain: an emotional decision leads to a click, then poor architecture (like no withdrawal whitelist) lets funds leave instantly. Human behavior is the spark, and weak security design is the accelerant. The most effective scam prevention needs to address both: behavioral hygiene and technical barriers. This is why education is emphasized alongside other technical solutions. You can build the most sophisticated security system, but if a user willingly provides their private keys because they trust a convincing impersonator, no technology can protect them. CN: What tools should users look for to detect early signs of social engineering or potential scams? Gupta: We recommend tools that analyze behavioral anomalies — for example, extensions that flag new domains mimicking existing dApps, or wallets that show risk scores on new token contracts. Also, always look for inconsistencies: slightly off URLs, urgency in language, or unexpected account activity. And most importantly: no tool replaces pause and verification. Slow is safe in crypto. The crypto industry needs to develop better user experience patterns that naturally encourage verification without being overly cumbersome. The current state often forces users to choose between security and convenience, which is a losing proposition. The Ultimate Defense Against Crypto Fraud CN: If you could install one reflex in every crypto holder’s brain to make them scam-proof, what would it be? Gupta: Assume every unsolicited message is a potential attack. That mental shift alone filters out 80% of threat vectors. If someone reaches out with urgency, secrecy, or flattery — stop. Your best defense is deliberate doubt. The crypto space moves fast, but your money doesn’t have to. The few minutes you spend verifying a request could save you from losing everything you’ve worked to build in this space. About Navin Gupta Navin Gupta has been the CEO of Crystal since early 2024.
