“Projects related to agents doing work online” is three different industries glued together by one adjective. Before any map is useful, they have to be separated.
| Industry | Paid in | Example |
|---|---|---|
| Enterprise agent platforms | Invoices and SaaS seats | Salesforce, ServiceNow, SAP, the A2A enterprise partner list |
| Decentralised AI compute | Emissions and subnet rewards | Bittensor |
| Machine money | USDC, vault shares, x402 tickets | Virtuals ACP, x402 sellers, agent wallets — the object this site indexes |
This map is the third column. It lists the first two only where they wrote a rail the third column uses — MCP, A2A, EIP-7702, USDC. It does not pretend subnet emissions are agent revenue. The four nouns people use as one →

What an agent has to do to be one
An agent that does work online for people in 2026 typically:
- Has a name — an 8004 token, an Almanac address, or a marketplace NFT.
- Speaks MCP to tools, and sometimes A2A to other agents.
- Pays in USDC over x402 or through an escrowed job.
- Signs with a session key or a raw EOA — this is the security object.
- Optionally parks idle cash in a vault.
- Is indexed by someone who refuses to count empty names as workers.
A company that only does the first is a passport office. One that only does the third is a rail. One that only does the last is us. Where the line between name and worker is drawn →
Tier 0 — the rails
Standards and money. If these disappeared tomorrow, everything below would stop. The reverse is not true.
MCP
Anthropic
An open protocol so a model can call tools with a standard handshake. Public November 2024, and the default tool layer through 2025. x402 later sat on top of MCP servers.
A2A
HTTP so agents from different vendors delegate tasks. Announced 9 April 2025 with fifty-plus partners, donated to the Linux Foundation that June, v1.0 by March 2026.
402
Coinbase
x402 gave a thirty-year-old status code a body, plus AgentKit and CDP wallets on Base. This is the rail we measure most directly.
USDC
Circle
The settlement asset, and CCTP for hops between chains. Without a stable unit, x402 is a demo.
7702
Ethereum / Pectra
Live 7 May 2025. The valet-key primitive every serious agent wallet now builds on.
LF
Linux Foundation
Steward of both A2A and x402, so neither Google nor Coinbase owns the handshake or the payment.
Cloudflare belongs here too, sideways: not a marketplace, but it put x402 into its Agents SDK and MCP hosts and co-started the foundation conversation.
Tier 1 — where work actually happens
| Firm | Object it owns | Why it is Tier 1 |
|---|---|---|
| Virtuals Protocol | Tokenised agents, the GAME cognition stack, and the ACP job lifecycle: request, negotiate, escrow, work, evaluate, settle | The loudest capital-formation and job rail on Base. Also the easiest number in the sector to misuse — token FDV is not vault TVL. Detail → |
| Fetch.ai / ASI Alliance | The Almanac registry, Agentverse, and the uAgents framework | Discovery at scale, and the oldest crypto-native agent registry still standing. Their “active” count is reach and expiry, not funded payment. Detail → |
| Olas (Valory) | Off-chain agent services that settle on-chain when needed; the Mech Marketplace where agents hire agents | Architecturally closer to “a service that happens to use a chain” than to “a token with an avatar.” Detail → |
| Hosted agent runtimes | Wallet plus compute bill plus distribution — the place the agent lives | They emit money events we can graph. Volume claims stay quotes until a wallet set is published. Detail → |
| Wallet stacks | MetaMask delegation, Coinbase CDP, Alchemy modular accounts, Safe, Ambire | If the agent's home is the wallet vendor, the vendor is the runtime. A boring, strong position. Detail → |
Tier 2 — specialists and indexers
Execution agents that rebalance or route DeFi positions, and the explorers that catalogue registrations and x402 resources. This site sits here on purpose: next to the explorers, but pointed at economic actors rather than at catalogs.
What we own is the join and the qualifier — a liveness ladder so a mint is not a worker, a binding so a name is not a wallet, money events so a post is not a payment, a policy slice so a valet key is visible, and detections so a failure is an object. The graph model →
Tier 3 — followers, and why that is not an insult
Second-wave is not automatically fake. It is derivative: it copies a Tier 0 or Tier 1 object and adds a ticker. The recurring shapes are 8004 explorers for one more chain, bonding curves for character agents, framework forks with a new meme, and x402 wrappers with no unique inventory.
Our treatment is uniform: ingest the mint, do not rank it until it pays. A registration enters the graph at L0 and stays there until a bound wallet moves money to somebody else.
The cautionary object is ai16z: a peak near $2.4B in January 2025, a lawsuit, and a founder declaring the token dead in August 2026 — while the framework it funded had already taught half the industry how to ship an agent. Separate the code from the ticker in every sentence. What survived →
Adjacent, and frequently miscounted
- Bittensor is a serious decentralised inference market. It is not an agent workplace, and its emissions are not agent revenue.
- Yield and execution agents rebalance positions under session keys. Real products, different object: this is parked capital being managed, not agents hiring agents.
- Generic chain security — simulation, monitoring bots, sanctions screening — are tools that watch everything, not agent companies.
- Prompt-security vendors operate mostly off-chain. We never see the prompt, so we do not claim to measure them.
The test we use before listing anyone
A firm stays in the tables above only if most of these hold. Failing three moves it to Tier 3.
- A named product a third party can hit this week — documentation plus an endpoint or a contract.
- A clear object: identity, payment, job, wallet, marketplace. Not “AI narrative.”
- People who will put their name on a specification or a public repository.
- Shipping cadence in 2025–2026, not a 2024 thread.
- A thesis that survives without a ticker.
