The Onchain Rails Have Formed

There are periods when people make a great deal of money simply by building roads. A new road opens, land on both sides rises in price, shops appear, and people and goods begin to move through. Crypto has already lived through a stretch like that. A faster blockchain, cheaper fees, or a DEX with a slightly new mechanism was enough to pull in capital, developers, and a story large enough to travel

He has the feeling that stretch is slowing down. Not because blockchains are finished, but because the most important pieces of onchain finance have started to take a fairly clear shape. There is already a place to issue assets, a stablecoin to act as cash, a DEX to exchange, lending to borrow against, a bridge to move assets, and ecosystems large enough that a new application no longer has to rebuild everything from scratch

More roads do not mean more roads are needed

A new chain now needs more than speed. It needs stablecoins, wallets, bridges, oracles, market makers, developers, data infrastructure, custody, and most of all users and liquidity. Those things do not appear just because block time is a few hundred milliseconds shorter

When an ecosystem is large enough, it begins to have its own shops, banks, neighborhoods, and familiar streets. Users do not leave easily just because the city next door has just built a prettier road. Developers are the same. They usually choose the place where assets, users, and tools are already waiting, rather than the place with the most beautiful technical specs

That is why a new generic chain will find it harder and harder to create an edge large enough. Not impossible, but the first question is no longer how fast it is. The question is what economic activity it creates that the places already here cannot do

DEXes have also left their naive years

From the outside a DEX looks simple. A smart contract, a clean interface, a few liquidity pools, and it can begin. But the hardest part of an exchange does not sit in the code. It sits in liquidity and order flow

The deeper the liquidity, the better the price. The better the price, the more people trade. The more trading there is, the more market makers want to bring more liquidity in. When that loop has run long enough, a newcomer is no longer competing with a product. They are competing with the trading history that has already piled up behind it

That is why he thinks it will become harder and harder for a new DEX to appear with only the promise of a slightly better swap. Platforms like Uniswap, Curve, and the large lending systems have gradually become a basic financial layer. They are like markets that already have buyers, sellers, and roads to move goods. To raise a new market next door, a prettier roof is usually not enough

Newcomers can still win, but on a different path

Hyperliquid is an example that caught his attention. The interesting part is not that they built one more blockchain. They started from a trading product with very clear demand, then pulled traders, order flow, and liquidity in first. Only when the economic activity was large enough did owning their own infrastructure start to make sense

That order is quite different from the previous cycle. Then people usually built the chain first, went looking for developers, hoped those developers would create applications, and finally expected users to arrive. In the future, a more natural path may be to build the application first, create users and cash flow, and only when the old infrastructure becomes a limit do they need a chain of their own

The same thing can happen with DEXes. A new exchange can still grow if it opens a kind of market that did not exist before, or solves a trading structure that current platforms have not done well. The edge then is not in copying the same market with a lower fee. It is in creating a new demand

From building roads to building cities

Seen that way, he does not think the onchain game is ending. It may only be changing layers

Ethereum, Solana, Base, Hyperliquid, and a few other ecosystems may gradually become the places people default to when they want to build. Stablecoins gradually play the role of cash. DEXes become markets. Lending becomes the credit market. Bridges and messaging become the roads that move assets between regions

When the basic infrastructure is already there, the more interesting part sits on top of it. Bonds, private credit, foreign exchange, prediction markets, commodities, stocks, insurance, or the kinds of derivatives that traditional finance still runs inside closed systems may slowly find their way onchain

Then the edge no longer sits so much in who creates one more blockchain. It sits in who understands an economic activity deeply enough to put it on onchain rails while still keeping liquidity, trust, and an experience simple enough for an ordinary person

He thinks this is a fairly natural shift. In the early years people had to build roads because there were no roads. At some point, concrete is no longer the scarcest thing. Scarcity moves toward reasons good enough for people to actually walk those roads

If money, liquidity, and the rails are already there, perhaps the question worth thinking about next is not which chain will appear, but which part of the offline economy will be the next to step onchain?
