Why I Started Writing: A Note on 0xMiikey

Seven years of building payment infrastructure, crypto protocols, and AI products. Here is why I finally started writing it down.

Writing and building

I’ve been building in the intersection of fintech, crypto, and AI for seven years. For most of that time, I didn’t write publicly. The reasons were the usual ones: too busy, the thoughts weren’t ready, someone else had already said it better.

None of those reasons were good enough.

Team collaborating at a desk — the people and problems that drive the writing Writing forces you to know what you actually think — and who you want to think alongside

Why Now

The honest answer: the pace of change in our space has gotten fast enough that I want a record of how I was thinking at each moment.

In 2019 I wrote internally about why stablecoin settlement rails would matter for cross-border payments. In 2021 I wrote about DeFi infrastructure surviving the speculative mania. In 2022 I had views about FTX and what custodial trust actually requires. In 2023 I had early takes on LLMs in production financial applications.

Some of those views were right. Some were wrong. All of them were formed in real context, with real stakes, at a moment in time when the outcome wasn’t obvious.

That’s the kind of writing I want to do. Not the hindsight-obvious retrospective. The in-the-moment, this-is-what-I’m-seeing, here-is-my-reasoning kind.

The most valuable writing isn’t the hindsight-obvious retrospective — it’s the in-the-moment record: this is what I’m seeing, here is my reasoning, and the outcome isn’t obvious yet. That’s the only kind worth doing.

What This Is Not

This isn’t a newsletter about crypto prices or AI model benchmarks. There are better places for that.

It’s not a personal brand exercise. I’m not trying to become an “influencer” in the fintech or crypto space.

It’s a working document. A record of how I think about building payment infrastructure, managing engineering teams through volatile markets, navigating the intersection of crypto-native and traditional financial systems, and deploying AI in contexts where being wrong is expensive.

What I’m Working On

Currently focused on:

  • Scaling cross-border stablecoin settlement infrastructure
  • MPC-based custody for institutional payment operations
  • AI-driven payment routing and risk decisioning
  • Team and organizational design as AI changes what “engineering” means

These are the problems I think about every day. The writing will reflect that.

The Handle

0xMiikey. The 0x prefix is the Ethereum convention for hexadecimal values — it’s how addresses, transaction hashes, and raw data are represented on-chain. It’s also how I think about the intersection I operate in: one foot in the cryptographic, one foot in the financial.

It felt right.


If you’re building in payments, crypto infrastructure, or AI-augmented products — I’d like to know what you’re seeing. The most useful thing writing does is create the conditions for good conversations.
