Who Is James Hunsaker? Monad Co-Founder, Category Labs CEO

James Hunsaker is a co-founder of Monad who in December 2024 was named CEO of Category Labs, the company that develops the technology behind the Monad blockchain. Category Labs is the renamed Monad Labs. On the day it took that name, the Monad Foundation launched beside it to support the network, and Hunsaker stayed with the software and research side.

In December 2022 Hunsaker made the first commit to the code repository for Monad's execution client, the part of its node software that runs transactions. By early November 2026 he had made about 15% of the repository's commits, more than anyone but one other contributor. After Monad's mainnet launched, though, his share of new commits fell to about 3%.

Who Founded Monad?

Monad's own channels name James Hunsaker and Keone Hon among its co-founders. When Monad Labs renamed itself, its announcement said Category Labs would "continue to be led by cofounder James Hunsaker, who serves as CEO."

Hon gets the same title on The Pipeline, a Monad podcast hosted by a Monad Labs team member. A June 2025 episode introduced him as a Monad co-founder.

Monad itself is a Layer 1 blockchain built around the Ethereum Virtual Machine, the engine that runs Ethereum's programs. That means you can take a smart contract compiled for Ethereum and deploy it on Monad without recompiling, according to Monad's technical overview.

The code history has a clear first entry. On 14 December 2022, Hunsaker's GitHub account made the "Initial commit" of the repository that now holds Monad's execution client. It was a starter commit holding only a licence and a settings file.

What Does Category Labs Do?

Category Labs develops the technology underlying the Monad blockchain. It calls itself a core contributor to the protocol. In its announcement it said it had pioneered "a new database for efficiently storing Ethereum merkle trie, a new BFT consensus mechanism, and a means of optimistic parallel execution of Ethereum transactions."

Each of those maps to a job a Monad node does all day. The database stores the chain's state, every account balance and every contract's data, in the tree structure Ethereum uses. The consensus mechanism is how validators agree on each new block, and BFT (Byzantine fault tolerant) means it keeps working even when some of them misbehave.

Parallel execution means Monad runs many transactions at the same time and then commits the results in their original order, according to Monad's technical overview. It re-runs any transaction whose inputs changed in the meantime, so the outcome matches running them one by one.

It's like a kitchen that cooks several orders at once but serves them in the order they came in, remaking any dish that used an ingredient an earlier order had already taken.

Every transaction pays a gas fee for the computing it uses. On Monad you pay for the whole gas limit you set, with no refund for gas left unused, because Monad builds a block before it runs the block's transactions.

Who Is the CEO of Monad?

Category Labs' team page lists James Hunsaker as CEO, and Category Labs is the company that builds Monad's core software. The title dates to 16 December 2024, when the post that launched the Monad Foundation said "Category Labs will be led by James Hunsaker, who will serve as CEO."

That day Monad's company split in two. The Monad Foundation described itself as "an independent organization dedicated to encouraging the development and adoption of the Monad blockchain protocol." Its launch post gave it the job of facilitating validator-led governance and running ecosystem development and marketing for the network. The post said Keone Hon and Eunice Giarta would join it, along with part of Monad Labs' business and community staff.

So if you're asking who runs Monad, the answer comes in two parts. One is Category Labs, the engineering company that writes the client software, with Hunsaker as CEO. The other is the Foundation, created to look after governance and growth. The December 2024 posts that set up the split give no one the title "CEO of Monad."

James Hunsaker's Career, From Trading Systems to Category Labs

Hunsaker came to blockchains from trading technology. In a March 2025 interview on the Y-Axis Podcast, he talked through his move from trading systems to blockchain engineering. The show notes also describe his management style, built on flat teams and the value of playing devil's advocate.

At Monad Labs, Hunsaker was co-founder and CTO. Older podcast pages still use that title, and it describes the job he held before Category Labs made him CEO.

In September 2025 Monad published its full client as open source under the GPL-3.0 licence, so anyone can read and reuse the code. Mainnet, the live network where real transactions settle, followed on 24 November 2025.

What Did James Hunsaker Build in the Monad Client?

Hunsaker made the second-most commits to Monad's execution client by early November 2026, though few came after mainnet. A commit is one saved change to a project's code, and GitHub records each one with its author and date, so you can see who saved what and when.

The execution client, the half of Monad's software that keeps the chain's state and runs its transactions, has its own repository. Its main branch held 4,400 commits, and Hunsaker made 679 of them, about 15%. That put him second on GitHub's contributor list, nine commits behind the leader, and the two of them made nearly a third of all commits.

GitHub's list held 61 entries, but not 61 people. Two are automated bots, and a few contributors appear more than once under different email addresses. Merge those and still no one but the leader passes his count.

Before mainnet Hunsaker made nearly a fifth of the repository's commits, and afterwards about one in thirty, with none between late June and early November 2026. In the separate consensus repository he made a single commit, in December 2024.

A commit count measures how often someone saves work, not how much code or design was theirs, and it doesn't explain why Hunsaker's share fell. Read plainly, it's the record of an engineer-founder who opened the code history and carried a large part of it until launch.

Can You Trade MON on Phemex?

Yes, on the spot market. MON is the token Monad's gas fees are paid in, and it trades on Phemex as a spot pair against USDT. Phemex no longer lists its perpetual futures contract. The spot pair has been on Phemex since mainnet day, 24 November 2025. On a spot pair you pay the full price and own the coins outright, the main way spot trading differs from margin trading.

On 21 January 2026, Hunsaker's Category Labs announced that it may purchase up to $30 million of MON on the open market in the first half of 2026, a footnote in a Monad Foundation token update records.

Phemex's futures markets cover other coins. Futures are a form of leverage trading, and a leveraged position is closed automatically if losses reach its margin.

Frequently Asked Questions

What language is the Monad client written in?

Two languages. Monad's technical overview says the client was written from scratch in C++ for execution and Rust for consensus. That makes the repository Hunsaker opened in 2022 the C++ half, and GitHub lists C++ as its main language.

How fast are Monad blocks?

A new block comes every 300 milliseconds, according to Monad's technical overview. A block is final 600 milliseconds after it's proposed, when the block two after it arrives. The overview's July 2026 update lists both as down from 400 and 800 milliseconds.

What software does a Monad node run?

Three programs, Monad's technical overview says. One runs consensus, one executes transactions and keeps the chain's state, and one handles users' reads and writes. Every node executes every transaction and holds the full state.
