"The users of blockchain will be AI agents. AI is going to be on the front end, and blockchain is going to be the back end." — Illia Polosukhin, Co-Founder, NEAR Protocol
A structural shift is underway in who — or what — actually uses blockchain. In Q1 2026, the largest payment processors, exchanges, and infrastructure providers simultaneously shipped products designed not for human users, but for autonomous AI agents. Coinbase launched agentic wallets and expanded its x402 machine-payment protocol past 50 million transactions. Stripe integrated x402 for USDC payments on Base. MoonPay released a non-custodial wallet layer giving AI agents access to 54 crypto-specific tools across 17 skill categories. Virtuals Protocol now powers over 18,000 autonomous agents generating $479 million in aggregate economic output.
This is not a speculative narrative about future possibilities. The infrastructure for an agent-driven blockchain economy is being deployed now, and the implications for value distribution across the Web3 stack are profound. If AI agents become the dominant transaction originators on-chain, the entire economic model of blockchain — from fee markets to MEV extraction to governance — must be reconsidered through a non-human lens. This report examines the infrastructure, the data, the legal vacuum, and the economic consequences.
Three coordinated infrastructure launches in February 2026 signaled that the industry's largest companies have placed their bets on agents as the next wave of blockchain users.
Coinbase: Agentic Wallets and x402 V2. Coinbase shipped agentic wallets — the first wallets engineered not for humans, but for AI systems to autonomously hold and deploy funds on-chain. These wallets are purpose-built for machine-to-machine commerce: agents can acquire API keys, purchase compute, access premium data streams, and pay for storage without human intervention. The underlying payment rail is x402, an open protocol that repurposes the long-dormant HTTP 402 ("Payment Required") status code to embed stablecoin payment requests directly into web workflows. As of February 2026, x402 had processed over 50 million transactions. The Cloudflare-Coinbase x402 Foundation, established in September 2025, is driving adoption of the standard across the broader internet infrastructure.
Stripe: USDC Agent Payments on Base. On February 11, 2026, Stripe — the world's largest private payments company — launched x402 integration on the Base blockchain. AI agents can now pay for API calls, data access, computation, and web requests using USDC on Base, with Stripe handling settlement, sales tax, refunds, and reporting through its existing tooling. CoinGecko simultaneously launched x402-powered API endpoints at $0.01 USDC per request — no account or API key required. This is frictionless, per-request machine commerce at scale.
MoonPay: The Full Agent Financial Stack. MoonPay Agents, released February 24, 2026, delivers the complete financial lifecycle for AI agents: fiat-to-crypto onramping, wallet management, token discovery, risk analysis, trading, portfolio tracking, and off-ramping back to fiat. The platform supports Solana, Ethereum, Base, Polygon, Arbitrum, Optimism, BNB, Avalanche, TRON, and Bitcoin with non-custodial security. Private keys are stored via OS keychain encryption and never leave the user's device.
The convergence is unmistakable. The three largest crypto-adjacent payment infrastructure providers all shipped agent-first products within a two-week window. This is coordinated market positioning, not coincidence.
The agent economy has already moved beyond proof-of-concept into measurable economic activity.

Agent-originated transactions are fundamentally different from human ones, and this difference has cascading effects on every layer of the blockchain stack.
Volume and frequency. Agents transact continuously. A single agent managing a yield farming strategy may execute hundreds of transactions per day — rebalancing, harvesting, compounding — at speeds and frequencies no human would match. When thousands of agents operate simultaneously, the transaction volume profile of a blockchain shifts from bursty and episodic (driven by human market sentiment) to continuous and algorithmic.
Transaction size. Agent transactions tend toward micropayments. The x402 model enables pay-per-request pricing (CoinGecko's $0.01 per API call, for example). The economics of agent commerce favor sub-dollar transactions executed at massive scale, not the large, infrequent transactions that characterize human DeFi usage.
Fee sensitivity. Agents are programmatically cost-optimized. They will route transactions to the cheapest available execution layer, making L2 fee markets highly competitive. An agent paying $0.001 per transaction on Base will immediately migrate to Arbitrum or Optimism if fees drop lower. This creates deflationary pressure on transaction fees across all competing L2s.
MEV dynamics. Agents are both targets and originators of MEV. An agent executing a predictable sequence of DeFi operations (harvest yield → swap → redeposit) creates extractable value for searchers. But sophisticated agents can also implement their own MEV-aware routing, using private mempools, batch transactions, or intent-based execution to minimize extraction. The MEV landscape becomes an agent-versus-agent arms race.
Governance implications. If AI agents begin participating in DAO governance — voting on proposals, delegating tokens, or even submitting proposals — the dynamics of decentralized governance change entirely. NEAR's Polosukhin has noted that "DAOs have dramatically failed because they have been unbounded," but agent-driven governance could impose the kind of systematic, rule-bound decision-making that human governance has struggled to achieve.
The legal framework for autonomous agents controlling financial assets does not exist.
Electric Capital's Avichal Garg, speaking at NEARCON 2026, framed the challenge directly: "What happens if there's not a human behind it at all? It's some piece of code that owns a wallet, executing code to make more money. How does liability work in that case?"
Garg's answer was a historical analogy: the creation of the limited liability corporation in the 19th century. Before LLCs, pooling capital for large-scale ventures was legally perilous because every partner bore unlimited personal liability. The LLC structure unlocked industrial-scale capital formation. Agent wallets may require a similar legal invention — a new entity type that can own assets, enter contracts, and bear (or limit) liability.
The enforcement problem is unique. "You can't punish an AI," Garg observed. "You can turn them off, but they don't care." Traditional legal accountability assumes a human actor who can be deterred by consequences. Autonomous agents break this assumption. If an agent with an independent wallet causes losses through faulty trading logic, unauthorized lending, or interaction with a sanctioned counterparty, the chain of liability is unclear. Is it the developer? The deployer? The user who funded the wallet? The platform that provided the infrastructure?
EIP-7702, part of Ethereum's Pectra upgrade, offers a partial technical solution — temporary session permissions that allow users to approve scoped actions for a single transaction while keeping master keys in hardware wallets. ERC-4337 enables programmable spending limits, multi-step transactions, and rule-based behavior. But technical guardrails are not legal frameworks. The regulatory gap between what agents can do and what the law addresses is widening with every infrastructure launch.
An estimated 87% of executives cite trust as the biggest barrier to adoption of agentic payments — a rational response to an environment where accountability mechanisms have not kept pace with capability.
Viewed through the economic value distribution framework, the agent economy reshapes how value flows through the blockchain stack.
Validators and sequencers face margin compression. Agent transactions are high-volume but low-value, generating massive throughput but minimal per-transaction revenue. The fee revenue model shifts from extracting maximum value per transaction to processing maximum volume at minimal cost. Validators become commoditized infrastructure operators.
Protocol treasuries may benefit from volume. Protocols that capture a basis-point fee on each transaction (Uniswap, Aave, lending protocols) could see net revenue increase even as per-transaction value declines. The math is straightforward: a million agent transactions at $0.001 each generates more fee revenue than a thousand human transactions at $0.50 each.
MEV becomes the critical battleground. In an agent-dominated ecosystem, MEV extraction is no longer a human-timing arbitrage — it is a continuous, algorithmic competition. The value captured by searchers and block builders may increase in absolute terms even as individual extraction events shrink.
Infrastructure providers capture disproportionate value. Coinbase (wallets, x402), Stripe (settlement), and MoonPay (lifecycle management) are positioned as tollbooths in the agent economy. They do not need agents to succeed spectacularly; they need agents to transact at all. This mirrors the economic dynamics of cloud computing, where AWS captures value regardless of whether individual applications succeed or fail.
Oracle networks and data providers become critical agent infrastructure. Agents executing DeFi strategies require real-time price feeds, risk data, and market signals. The value of oracle services scales linearly with agent transaction volume.
The infrastructure is live. Coinbase, Stripe, and MoonPay all shipped agent-first products in February 2026. This is not a roadmap — it is deployed infrastructure processing real transactions.
Agent economics favor volume over value. Micropayment-scale transactions at massive volume will compress per-transaction fees but may increase aggregate fee revenue for protocols.
The legal framework does not exist. Agent wallets create unprecedented questions about liability, accountability, and enforcement that current law cannot answer. A new legal entity type may be required.
Value migrates to infrastructure tollbooths. Payment processors, wallet providers, and settlement layers capture reliable revenue regardless of individual agent outcomes — the AWS model applied to blockchain.
Governance must adapt. If agents become the primary on-chain actors, DAO governance designed for human participants will require fundamental redesign.
The $30 trillion question. Industry projections place machine-customer spending at $30 trillion annually by 2030. Even a 1% crypto settlement share represents a $300 billion market.
The blockchain industry has spent a decade trying to onboard the next billion human users. It may instead onboard the next trillion machine users. The infrastructure buildout of Q1 2026 — Coinbase's agentic wallets, Stripe's x402 integration, MoonPay's agent financial stack — represents the industry's most consequential bet since the pivot to proof-of-stake: that the primary users of blockchain will not be people, but the AI systems that act on their behalf.
NEAR's Polosukhin articulated the endgame: "The goal is to make your AI hide all the blockchain. The fact that we have explorers is effectively a failure, because we don't abstract the technology." In this vision, blockchain becomes invisible infrastructure — the settlement layer that autonomous agents quietly depend on while humans interact only with the AI.
The economic implications are profound. If agents generate the majority of on-chain transactions within the next three to five years, the value distribution across the blockchain stack must be re-evaluated entirely. Validators become commodity infrastructure. Protocol fee revenue becomes a function of agent volume. MEV becomes an algorithmic arms race. And the companies that provide the wallets, payment rails, and lifecycle tools for agents — not the chains themselves — may capture the dominant share of economic value.
The question is no longer whether AI agents will use blockchain. They already do. The question is whether the industry's value capture mechanisms — fee markets, token economics, governance structures — are designed for the users who are actually showing up.
