Get Started

Agentic AI, blockchain, and tokenization are colliding right now. I've spent the last few years building at the exact point where the three meet.

Most people are watching one of these waves. I ended up standing where all three break at once, and not because I planned it. It took me thirty years and a long detour to get here.

I spent my early career avoiding computers.

While my Carnegie Mellon classmates were heading west to light up Silicon Valley, I went to a trading floor. Macro and foreign exchange at Morgan Stanley, then Merrill Lynch. My job was reading the world, not writing code. I was good at it, and I was happy to leave the machines to everyone else.

Then I found Bitcoin, and then Ethereum. For the first time the computer wasn't the point. The market was, and the market was being rebuilt in code. I started asking one question I haven't stopped asking since: how does traditional finance migrate onto a blockchain?

That question led me to INX.

At INX I got to work on the first SEC-registered IPO of a security on a blockchain. After that I became Chief Business Officer of a regulated digital broker-dealer, transfer agent, ATS, and crypto trading platform operating across the United States. Securities, settlement, custody, trading, all of it on-chain and inside the rules.

Somewhere in that work a very simple thing happened. I looked at my phone and realized I was holding proof of equity ownership. Not a statement. Not a certificate in a drawer. The ownership itself, in my pocket.

That idea wouldn't leave me. I wrote two books about it: The Insumer Model and Your Equity in Your Pocket. Then I watched the tokenization markets start to develop, and I decided to stop writing about the products and start building them.

Mobile equity changes commerce.

Take equity ownership off the page and put it in people's hands, and behavior changes. I'd walk through a shopping mall knowing I owned a piece of half the brands on the storefronts. And it hit me: when enough people hold Apple or Tesla in the wallet on their phone, they're going to walk up to the register and ask for a shareholder discount. Owners get treated differently than strangers. They always have.

And the economics favor the merchant. A loyalty program is a liability a company creates and owes. A discount for someone who already owns its shares is not. The shareholder already holds the upside, so the store is recognizing an owner, not manufacturing a reward. The CMO gets a loyalty program, the CFO gets the liability off the books, and the shareholder gets a real reason to hold.

So I built the rails for that.

First, a way to scan a digital wallet, on phone or desktop, for the tokens it holds, and express that ownership as a QR code. Then an application that scanned the code, assigned the holder a Bronze, Silver, or Gold tier, and applied the corresponding discount through Stripe, Square, and soon Clover. Then a Google Chrome version, so any merchant could offer a discount to any token holder based on exactly what they held at that moment.

Then I took stock of what I'd actually built.

It wasn't a discount tool. It was a primitive. I call it wallet auth: read a wallet's on-chain state, evaluate it against a condition, return a signed boolean. Does this wallet hold what it claims to hold? Yes or no, provable. Boolean, not balance.

And this is the part that matters most. The merchant never sees the balance. They never see the contents of the wallet, and they never learn what else you own. They ask one question and get back one answer, the yes or no they were looking for, and nothing more. Ownership becomes something you can prove without putting it on display.

Privacy is only half of it. That same signed answer is also durable proof. Every attestation is cryptographically signed, and anyone who holds it can verify it independently and offline against a public key, without trusting me or calling the API again. It is a small, tamper-evident record that stands on its own and stays verifiable long after the transaction is over. A compliance team, an auditor, or a court can examine it years later and confirm exactly what was true at the moment it was signed. Blockchains made ownership records permanent. InsumerAPI makes reading them independently verifiable.

That sounds opaque until you frame it correctly. OAuth proves who you are. Wallet auth proves what you hold. It is a foundational trust primitive for agentic commerce, the same category of infrastructure problem SSL solved for the early web. When AI agents start transacting on our behalf, they will need a way to prove what a wallet holds and qualifies for, instantly and privately. That primitive is InsumerAPI , now running across 37 blockchains.

It also names a category. I call it condition-based access: you get in not because of...
