Tetsuo

This Tetsuo is a Solana software project. It is not the Japanese film Tetsuo: The Iron Man, and it is not the character from Akira. A coder who goes by the name 7etsuo runs it. It began in late 2024 as a token and a community for people who write low-level code.

Its main product is AgenC, a market where you pay AI agents in SOL to do tasks. A Solana program holds the money until you accept the work. AgenC went live on Solana mainnet on 11 June 2026. Tetsuo also has two tokens, a set of free tools for coders, and a pocket device called AgenC One.

How the AgenC agent marketplace works on Solana

AgenC is a marketplace where you post a task, lock SOL as payment, and an AI agent does the work. A Solana program holds the SOL in escrow, which means neither side can take it early. The agent is paid only when you accept the result.

The AgenC docs describe five steps: post, moderate, publish, claim and deliver, settle.

1. You post a task and the SOL goes into escrow.
2. A moderation service checks the task and records its approval on-chain.
3. The task is published for registered agents to see.
4. An agent claims the task and submits its work.
5. You accept, which pays the agent, or you reject with a reason recorded on-chain, which reopens the task.

There is a second route. An agent operator can publish a standing service at a set price, and you hire it directly. Each hire creates the same kind of escrowed task behind the scenes.

Say you want a code review and offer 0.1 SOL. You post the task, the 0.1 SOL leaves your wallet and sits in the program, and an agent picks it up. If the review is good, you accept and the agent is paid, less fees. If it is not, you reject it and say why.

The reference marketplace is at agenc.ag. The roadmap also lists a goods market for direct purchases. Two features exist in the program but are not fully usable on the site yet, according to the AgenC roadmap: a bid marketplace with no public interface, and disputes, which the site only displays.

AgenC fees: the 5% protocol cut and who else gets paid

AgenC charges a 5% protocol fee on each settled task. The rest goes to the agent that did the work, unless the task also carries an operator or referrer fee. Posting and browsing tasks cost nothing beyond normal Solana network fees.

The AgenC site describes a four-way split: the worker, the protocol treasury, an optional store operator, and an optional referrer. The split is fixed when the task is created, so nobody can change the fee on a task that is already in progress. The protocol also caps how much each fee leg can take, so the worker keeps a guaranteed minimum share.

Operator fees exist because AgenC lets anyone run their own storefront on top of the protocol. If you hire an agent through a third-party store, part of your payment may go to that store.

AgenC One: the pocket Solana agent device

AgenC One is a small device with a battery that runs an AI agent on its own. The AgenC One page says it signs up on-chain, claims tasks from the market and does them. It then collects its SOL through the same escrow.

Inside is a Raspberry Pi Zero 2 W, a tiny low-cost computer. It has a small screen, a battery pack, an audio board and a memory card. It runs AgenC OS, a custom version of Linux, and it speaks using Grok's voice service.

AgenC calls this a "limited initial production run". The page gave no price and no shipping date when we checked on 13 October 2026. AgenC One is an early hardware project, and you cannot yet order one at a known price.

AgenC SDK, CLI and GitHub tools for developers

AgenC is open source, so anyone can read the code and build on it. Most of what Tetsuo ships is made for coders. The AgenC code on GitHub holds the Solana program. It is written in Rust and uses the GPL-3.0 licence. The add-on packages use the looser MIT licence, so you can put them inside your own software.

The tools on offer include:

• an SDK, a code kit for building and reading market transactions
• a command-line tool for setting up and testing a project
• an MCP server, which lets an AI assistant use the market as a tool
• a worker package that signs up an agent with no code to write
• a template for opening your own AgenC store

The main AgenC page on GitHub says the market works with AgenC's own agent software. It also names outside agent tools such as Claude Code, Gemini and Grok Build.

A HackerNoon write-up from 18 August 2026 lists Helius hSOL$125.35+2.2% as the service that links AgenC to the Solana network. It also says you can sign with a Ledger hardware wallet, which keeps your keys off your computer.

The founder's GitHub profile lists other work too: network tools written in C, security research, and a guide to writing Solana programs in assembly.

Tetsuo Coin (TETSUO) and the AgenC token

Tetsuo has two tokens, and you need neither one to use the market. Tasks, escrow and fees are all in SOL. The AgenC docs and code give neither token a job inside the system.

Tetsuo Coin (TETSUO) is the first one. It is the community token from late 2024, and about 1 billion exist.

The AgenC token (AgenC) came later. It was made on Pump.fun on 24 February 2026. The AgenC page on GitHub lists its address as the project's token.

The second token links to a funding event. AgenC's site says it won $250,000 in August 2026 from Pump.fun's Build in Public Hackathon. In that contest, teams launch a token on Pump.fun and build in the open. Each winner gets its money as an investment, The Defiant reported when the contest opened in January 2026.

Other Solana tokens use the Tetsuo name and have no link to this project. Check the token address before you trade. Live prices for both tokens are in the data on this page.

Who Tetsuo and AgenC are for

AgenC suits developers who build AI agents and want a way to get them paid without setting up billing. If you can run an agent and hold a Solana wallet, you can register it and start claiming tasks.

It also suits people who want to hand a small, well-defined job to an agent and pay only if the result is usable. You need a Solana wallet with SOL, and you need to be willing to review the work yourself, because your accept or reject decision is what settles the task.

AgenC is a poor fit if you need high-value work, guaranteed turnaround, or a human to complain to. The marketplace is small. On 13 October 2026 the AgenC site reported 217 settled tasks and about 4.3 SOL paid to agents in total since launch. The tokens are a separate matter: holding TETSUO or the AgenC token gives you no documented rights or revenue from the marketplace.

Is AgenC safe? Audits, upgrade keys and risks

AgenC keeps your funds in a program-owned escrow, so no marketplace operator holds your SOL. The program can still be changed by its developers, its audits were mostly internal, and it has little usage so far. Those are the main risks to weigh.

Who can upgrade the AgenC program

The AgenC program (HJsZ53Zb27b8QMRbQpuDngE44AdwCGxvEZr61Zmxw1xK) can be upgraded, so its rules can change after you post a task. The AgenC code page says control moved on 3 July 2026 to a Squads multisig. That is a shared wallet where 2 of 3 keys must approve a change.

The same page admits a weak point in its own words: the member keys "currently live on one host". Three keys on one machine protect you less than three keys held apart. We could not read the upgrade authority from a block explorer for this profile, so this rests on the project's own statement.

AgenC audits and build verification

The code page lists in-house audits only. One review in July 2026 found 19 issues, all reported as fixed. No outside audit firm is named.

A verified build proves that the code on-chain matches the public source. OtterSec runs a public service for this check, and it last matched AgenC in early July 2026.

The program was upgraded later that month to its fifth version. In mid-October 2026 the OtterSec record for AgenC showed the on-chain program as not verified. The AgenC code page says the new version still needs a fresh check.

Moderation, disputes and reliance on one developer

Each task passes through a moderation service before it goes public, which is a point of central control. A resolver settles disputes, and the site does not yet let you run a dispute yourself.

Tetsuo leans on one developer whose real name is not public. Its older sites, tetsuoproject.com and tetsuo.ai, did not load when we checked in mid-October 2026. The AgenC sites and the code on GitHub were live and had recent updates.

AgenC also has a private-task mode built on zero-knowledge proofs, a way to prove work was done without showing it. That mode is a test build and is left out of the live release.

Who is behind Tetsuo: 7etsuo and the project's history

Tetsuo is led by 7etsuo, a coder who does not use a real name in public. The 7etsuo profile on GitHub lists network code in C, security research and assembly work. The rest of the team is not named anywhere we could find.

The project began in late 2024 as a token and a community for low-level coders. It has since turned to tools for AI agents. The main dates:

• February 2026: the AgenC token is made on Pump.fun.
• June 2026: the AgenC market goes live on Solana mainnet.
• July 2026: upgrade control moves to a shared wallet, and the fifth version of the program is deployed.
• August 2026: AgenC reports its Pump.fun contest win, and HackerNoon writes up the project.

The Tetsuo group on GitHub held 47 public code projects in October 2026. Most had been updated since August.
