The financial world has recently exploded—former U.S. President Trump announced he will sue JPMorgan Chase over the bank closing his account in 2021, which he claims is part of a "debanking" effort.

This may seem like political news, but it actually reflects a deeper issue: even individuals with top legal teams can be cut off from all financial services by a traditional financial institution with just a notice. And what about ordinary people? Our accounts, assets, and so-called financial freedom are incredibly vulnerable when faced with decisions made by centralized institutions.

Frozen bank accounts are not hypothetical—they are a reality. When your financial channels are unilaterally shut down by a compliance department, you truly understand what financial risk means. The money is still in the bank, but you can't access it—this helplessness is more despairing than being directly robbed.

So the question is: what is true financial security? It's not about how many bank executives you know, but about storing your assets in a system that cannot be arbitrarily frozen. Such a system shouldn't be controlled by a single company's compliance department but should be guaranteed by mathematics and code, with rules that are open and equal to all participants worldwide.

Decentralized finance on the blockchain offers this possibility. It doesn't require a banking license or rely on trust in traditional financial institutions, but instead uses smart contracts and distributed networks to ensure asset security and transaction transparency. Accounts cannot be frozen, and rules are applied equally to everyone.

Trump's lawsuit once again proves that the traditional custodial model has fatal flaws. On-chain finance represents a completely different path.
