On-Chain Finance Needs a Privacy Layer
That is what we are building with Armada: a privacy layer that financial products can easily plug into, concentrating stablecoin activity into a single shielded pool whose protection improves as more organizations use it.
By default, blockchains expose information that organizations normally keep private. Three years ago today, I published our privacy investment thesis: we predicted that this kind of exposure would prevent meaningful adoption and, like what HTTPS did for e-commerce, tech that enables private blockchain transactions would become essential infrastructure.
It’s 2026. I think we got the problem right and the order wrong. Adoption did not wait for privacy. Stablecoins carried an estimated $28 trillion in organic economic activity in 2025, growing at a compound annual rate of 133% since 2023 (Chainalysis, 2026). Stablecoin settlement is rising at breakneck speeds. Neobanks and financial platforms are becoming the operating layer for business money–for accounts, payroll, vendor payments, treasury, and investments. As these flows move on-chain, organizations gain programmability, but is it worth exposing their entire financial graph?
Payroll reveals personnel and comp. Vendor payments expose commercial relationships. Treasury movements broadcast balances and strategy. Investments unveil plans ahead of announcements. Together, these patterns give counterparties, competitors, and observers what they need to reconstruct the organization. As more of the global economy comes on-chain, increasingly-sophisticated chain surveillance will produce increasingly-valuable intel. Organizations need to control who can learn what and when. And BlackRock is not going to adopt an app like Railgun as its operating environment.
Instead they’ll use custody, treasury, and payment solutions that they already trust. Privacy must disappear into those products, and routine financial activity must be routed through a shielded pool that’s dense enough for effective privacy. Because privacy compounds with concentration, each additional flow strengthens the shielded pool for everyone (and fragmentation across specialized products weakens it). The winning privacy layer will be infrastructure, not an app. And it must be durable. Serious organizations cannot build critical operations on privacy that can be switched off.
The privacy category carries baggage. Some institutions may associate privacy with mixers and regulatory risk, because most privacy products were built around crypto-native activity, rather than ordinary business operations.
That is what we are building with Armada: a privacy layer that financial products can easily plug into. Payroll, treasury, and payment products continue to work the same as before, but with Armada below, making the USDC flows private. The flows join one shared pool, compounding, so the privacy improves as more products and organizations use it. Adoption’s happening, and fast. Privacy is the security that will determine how much of the global economy will follow.
