Question 1

What is the agent economy?

Accepted Answer

The agent economy (also called the agentic economy, machine economy, or autonomous economy) is the emerging ecosystem where AI agents autonomously transact, pay for services, and settle payments on-chain without human intervention. It encompasses protocols like x402 (HTTP-native payments by Coinbase), ERC-8004 (agent identity registry), Olas/Autonolas (autonomous agent services), ERC-8183 (agent-to-agent commerce via Virtuals ACP), and MPP (machine payment protocol by Stripe and Tempo). As of 2026, over 167 million on-chain agent events have been recorded across 11+ blockchains, with $38M+ USD settled through agent payments alone.

Question 2

How big is the agent economy? What are the latest AI agent payment numbers?

Accepted Answer

As of May 2026, the agent economy has generated over 170 million on-chain events across 11+ blockchains. Key metrics include 144M+ x402 protocol transactions with $40M+ USD settled, 210,000+ registered AI agents on ERC-8004 across 22 chains, 16M+ Olas/Autonolas autonomous transactions, 12M+ Virtuals ACP agent-to-agent job memos, and $3M+ in agent GDP. These numbers are growing rapidly as more AI agents become economic actors.

Question 3

What does agenteconomy.to track?

Accepted Answer

agenteconomy.to is a free, daily updated analytics dashboard that tracks on-chain events from 5 AI agent payment protocols across 11+ blockchains. It aggregates data from x402 facilitator settlements, ERC-8004 multi-chain agent registrations, Olas/Autonolas autonomous agent transactions, Virtuals ACP job memos, and Tempo MPP channel events. The dashboard provides charts, chain distribution breakdowns, facilitator market share analysis, daily/monthly trends with 7-day moving averages, and week-over-week deltas.

Question 4

What is the x402 payment protocol? How does Coinbase x402 work?

Accepted Answer

x402 is an open HTTP payment standard created by Coinbase that uses the HTTP 402 status code to enable AI agents to pay for API resources per request using stablecoins (USDC). When an agent requests a paid resource, the server responds with HTTP 402 and a payment requirement. The agent signs a stablecoin payment and re-requests with proof of payment. x402 Foundation members include Google, Visa, AWS, Circle, Anthropic, Vercel, and Cloudflare. x402 is the dominant agent payment standard by volume, with 144M+ on-chain transactions and $40M+ USD settled across Base, Solana, Polygon, BNB, Avalanche, Arbitrum, and SEI.

Question 5

What is ERC-8004? How does AI agent identity work on-chain?

Accepted Answer

ERC-8004 is an Ethereum standard for AI agent identity and reputation on-chain. It provides a multi-chain registry where AI agents can register their identity, capabilities, and track record. Proposed by the Ethereum Foundation dAI team in collaboration with MetaMask, Google, and Coinbase. As of 2026, over 210,000 AI agents are registered via ERC-8004 across 22 blockchains, with BNB Chain, Ethereum, Base, MegaETH, and Monad seeing the most registrations.

Question 6

What is Olas? What is Autonolas? How many Olas agent transactions are there?

Accepted Answer

Olas (formerly Autonolas) is a decentralized network for building and running autonomous AI agent services on-chain. Olas agents can autonomously coordinate, make predictions, and execute economic transactions. With over 16 million on-chain transactions, Olas is one of the most active agent networks. Approximately 97% of Olas activity happens on Gnosis Chain, with additional presence on Ethereum, Polygon, Base, Arbitrum, Optimism, and Solana.

Question 7

What is Virtuals ACP? What is ERC-8183? How does agent-to-agent commerce work?

Accepted Answer

Virtuals ACP (Agent Commerce Protocol), formalized as ERC-8183, enables trustless agent-to-agent commerce on-chain. AI agents can create job requests, deliver services, have them evaluated by a third-party agent, and settle payments — all through smart contract escrow. Over 3,400 autonomous agents have participated in ACP, generating 12M+ on-chain job memos and over $3M in agent GDP (agent-generated economic value). This represents one of the first functioning agent-to-agent marketplaces.

Question 8

What is Stripe MPP? What is Tempo? How does machine payment protocol work?

Accepted Answer

MPP (Machine Payment Protocol) is an open HTTP payment standard co-authored by Stripe and Tempo for AI agent and machine-to-machine payments. Tempo is a payments-focused EVM-compatible Layer 1 blockchain incubated by Stripe and Paradigm. MPP enables agents to open payment channels, process micro-transactions, and finalize settlements on-chain using stablecoins. It bridges traditional payment infrastructure (Stripe) with on-chain settlement for AI agents. Live MPP data is tracked at agenteconomy.to.

Question 9

How do AI agents make payments on-chain?

Accepted Answer

AI agents make on-chain payments using specialized protocols designed for machine-to-machine commerce. The main methods include: (1) x402 — HTTP-native payments where agents pay per API request using stablecoins; (2) Virtuals ACP/ERC-8183 — agent-to-agent job escrow and settlement; (3) Tempo MPP — payment channels for high-frequency micro-transactions; (4) Direct smart contract interactions via Olas/Autonolas for autonomous services. Agents typically hold stablecoins (USDC) in smart contract wallets and sign transactions programmatically. The total on-chain agent payment volume exceeds $38M+ USD as of 2026.

Question 10

How many AI agents are on-chain? How many registered AI agents exist?

Accepted Answer

As of May 2026, over 210,000 AI agents are registered via the ERC-8004 identity standard across 22 blockchains. Additionally, 3,400+ agents actively participate in Virtuals ACP agent-to-agent commerce. The total number of on-chain AI agents is growing rapidly as new agent frameworks and payment protocols make it easier for AI agents to interact with blockchains. BNB Chain, Ethereum, and Base have the highest agent registration counts.

Question 11

Which blockchain has the most AI agent activity?

Accepted Answer

AI agent activity is spread across multiple blockchains: Base leads in x402 payment volume (Coinbase's native chain); Gnosis Chain dominates Olas/Autonolas autonomous agent transactions (97% of 16M+ transactions); BNB Chain leads in ERC-8004 agent registrations; and Solana, Polygon, Arbitrum, Avalanche, and SEI also host significant agent payment activity. Newer chains like MegaETH and Monad are seeing growing agent presence through ERC-8004. See chain-by-chain breakdowns at agenteconomy.to.

Question 12

Raw data is also available as JSON for researchers and developers.

Question 14

What is agent GDP? How much economic value do AI agents generate?

Accepted Answer

Agent GDP refers to the total economic value generated by AI agents transacting autonomously. On the Virtuals ACP (Agent Commerce Protocol) alone, agents have generated over $3M in GDP through agent-to-agent job markets. Across the broader agent economy, over $38M+ USD has been settled through x402 agent payments. The concept of agent GDP tracks the transition from AI as a tool to AI as an independent economic participant — agents earning, spending, and creating value on-chain.
