If you were to close your eyes and summon the ghost of 2020, you would likely smell the digital equivalent of ozone and gunpowder. It was the era of the “DeFi Summer,” a period that felt less like a financial revolution and more like a high-stakes arcade game played in a fever dream.
We were all alchemists then, trying to turn food tokens Yam, Sushi, Pickle, into gold. The air was thick with $1,000\%$ APY promises, Discord servers that never slept, and the constant, thrumming anxiety that a rug-pull was just one smart contract interaction away. It was the Wild West, a lawless frontier where the only rule was speed, and the only metric was the meteoric rise of Total Value Locked (TVL).
Fast forward to 2025, and the landscape has been terraformed. The smoke has cleared, the saloons have been replaced by polished glass towers, and the alchemists have been joined by architects. The story of DeFi over these last five years isn’t just a story of “going mainstream”; it’s a story of a fundamental, molecular change in what decentralized finance actually is.
We want to extend a sincere thanks to our distinguished guests for sharing their frontline perspectives: Vivien Lin, Chief Product Officer & Head of BingX Labs; Griffin Ardern, Head of BloFin Research & Options Desk; and Fernando Lillo Aranda, Marketing Director at Zoomex. Their insights allow us to map the vast distance between the speculative madness of the past and the sophisticated clarity of the present. Together, we are dissecting a fundamental, molecular change in what decentralized finance actually is.
The Anchor of Reality
In the 2020 version of the “Wild West,” DeFi was a closed loop. It was a beautiful, chaotic bubble where we borrowed one volatile asset to stake it for another even more volatile asset. It was a self-referential machine that lived and died by its own internal hype. But as we sit in 2025, that loop has been broken, and the “real world” has poured in.
Vivien Lin, Chief Product Officer & Head of BingX Labs, reflects on this profound shift from the speculative to the foundational. When asked about the biggest difference between the chaos of five years ago and today, she points to a hardening of the asset base itself.
“The biggest shift is the integration of real-world assets and stablecoins into what was once a purely speculative environment,” Lin observes.
This is the maturation of the “DeFi Summer” into a “DeFi Autumn,” a season of harvest and stability. In 2020, we were chasing ghosts. In 2025, we are trading the bedrock of the global economy. The “high yields” of the past were often just a tax on latecomers; today’s yields are generated by the actual productivity of government bonds and real estate.
The New Yardstick: Quality Over Quantity
In the old days, if we can call five years ago “old” we were obsessed with TVL. It was the only number that mattered. We watched the billions pile up like a scoreboard in a stadium. But we eventually learned that TVL was a deceptive god. Much of that value was “recursive”, a house of cards built by lending the same dollar ten times over.
As we navigate 2025, the industry has developed a more cynical, and therefore more healthy, eye for data. We no longer ask “How much is locked?” but “What is actually being used?”
Vivien Lin notes that our old metrics have been replaced by a search for genuine signal amidst the noise.
“There is no universal metric because it depends on what you are evaluating,” Lin explains:
When you look at a stablecoin, you aren’t looking at a “moonshot” or a meme. You are looking at a digital dollar, a vote of confidence in the underlying infrastructure. In 2025, a protocol’s health is measured by its ability to attract stable, non-volatile capital. This shift in metrics represents a shift in the very psychology of the market: from gambling to banking.
The Suits in the Server Room
For years, the cypherpunks and the degens laughed at the idea of big banks entering DeFi. “They’ll never understand it,” we said. “The regulations will stop them,” we thought. But the banks didn’t come to DeFi to join a revolution; they came because the old plumbing of the financial world was leaking, and DeFi offered a new set of pipes that were faster, cheaper, and impossible to clog.
However, the banks didn’t enter through the front door of anonymous DEXs. They built their own entrance. Griffin Ardern, Head of BloFin Research & Options Desk, paints a picture of an institutional DeFi that looks remarkably like a more efficient version of the traditional world.
Ardern says:
This is not the DeFi of 2020, where you could trade millions with nothing but a wallet address. This is a regulated, “permissioned” DeFi. Ardern sees this as the birth of a new kind of global market.
Ardern continues:
This is a crucial insight. The “Interbank” market, the hidden world where banks lend to each other, is the engine of the global economy. By moving this engine onto the blockchain, banks are gaining the transparency they never had before. In the 2008 crisis, banks stopped lending because they didn’t know who was solvent. In the DeFi-enabled interbank market of 2025, solvency is verifiable on-chain in milliseconds.
The Magnetism of Real-World Assets (RWA)
The bridge that finally allowed the “suits” to cross into the world of the “hoodies” was the tokenization of Real-World Assets (RWA). In 2020, we talked about “putting the world on-chain.” In 2025, we are actually doing it. Whether it’s a fractionalized apartment in Berlin or a U.S. Treasury bill, the blockchain has become the ultimate ledger of record.
But according to Vivien Lin, we shouldn’t mistake the instrument for the incentive. Banks aren’t here just because they love tokenization; they are here because the users moved first.
“RWA tokenization is a major catalyst, but it is not the sole reason banks are entering the space,” Lin points out. She adds:
Every time a retail user swaps a traditional savings account for a tokenized yield-bearing stablecoin, a bank loses a deposit. To survive, the banks have had to follow those dollars onto the chain. It is a rare example of the “little guy” forcing the hand of the giants through the sheer gravity of capital.
The Privacy Paradox: The New Guard vs. The Newbies
While the institutional side of DeFi is becoming more transparent and compliant, a different battle is being waged at the user level. As regulations tighten in 2025, a segment of the market is retreating into the shadows, while the “average” user is still struggling to find the front door.
Fernando Lillo Aranda, Marketing Director at Zoomex, sees a growing schism in how people interact with the space. On one hand, there is a surge in demand for total sovereignty.
“What we can see is a rise in the users/traders looking for DEX and CEX with 100% Privacy, they want to continue building his privacy to avoid regulations and sanctions,” Aranda observes.
This is the lingering spirit of 2020—the desire to operate outside the gaze of the state. But for the “mass retail” user that DeFi so desperately wants to attract, this focus on privacy and self-custody is actually a barrier. The “Wild West” was exciting for the pioneers, but it was terrifying for the settlers.
Aranda admits:
This is the “User Experience” wall. In 2020, you needed a PhD in “Metamask-ology” to survive. In 2025, the interfaces are beautiful, but the underlying fear remains: If I lose my keys, I lose my life savings. This is why Centralized Exchanges (CEXes) still dominate the narrative for the average person. They provide the “undo” button that decentralized finance, by its very nature, lacks.
Is It Safe Yet?
The question that haunts every columnist and developer in 2025 is the same one we asked in 2020: “Is it safe?” In 2020, the answer was a resounding “No.” In 2025, the answer is “Yes, but…”
Vivien Lin believes the path to safety isn’t just about better code, but about better tools to help us navigate that code.
“DeFi is safer and more intuitive than it has ever been, but each user should always approach it with clear goals and a plan,” Lin warns.
The introduction of AI as a “financial co-pilot” in 2025 has changed the game. Instead of reading through pages of smart contract audits, users now have AI agents that can scan a protocol for vulnerabilities in real-time or explain the risks of a specific liquidity pool in plain English. The complexity hasn’t disappeared—it’s just been buried under a layer of intelligent design.
The Conclusion of the Frontier
The journey from 2020 to 2025 is the story of a market growing up. We have moved from the “DeFi Summer” of speculation to the “DeFi Standard” of global finance.
We see the vision of Griffin Ardern, where the “offshore interbank market” is being rebuilt on a transparent ledger. We see the pragmatism of Vivien Lin, who recognizes that stablecoins and RWAs have anchored the industry to reality. And we see the honest appraisal of Fernando Lillo Aranda, who reminds us that for all our progress, the human need for simplicity and trust still drives the majority of users toward centralized hubs.
In 2020, DeFi was an experiment that might have failed. In 2025, DeFi is an infrastructure that must work. The “Wild West” has been tamed, not by the sheriff, but by the engineers, the bankers, and the millions of users who decided that their dollars were better off on a blockchain than in a vault.
The story isn’t over. The tension between privacy and regulation, between decentralization and ease-of-use, will define the next five years. But as we look back at the chaos of 2020 from the vantage point of 2025, one thing is clear: we aren’t playing a game anymore. We are building the future of money, one block at a time.
