Completing Anthropic’s Token Economy

Anthropic Built the “Token” — Exe’s Building the Missing Settlement Layer for AI-Native Commerce

The $5 Billion Accidental Financial System

In February 2025, Anthropic was closing $3.5 billion in new funding at a $61.5 billion valuation. The headlines focused on AI capabilities — Claude 3.7 Sonnet, extended thinking, enterprise adoption. But beneath the press releases, something more profound was happening: Anthropic had built an “accidental” financial system.

Most people think of Anthropic as only a model provider. But scratch the surface and Anthropic has created a machine-to-machine (M2M) economy at scale.

Think about that for a minute: their API doesn’t just serve requests. It settles transactions between artificial agents and the infrastructure they consume. API credits function as a medium of exchange within a closed ecosystem, covering:

• Prepaid balances
• Transactional velocity
• Counterparty relationships between autonomous systems

Sound familiar? It should. This is how currencies begin.

By using AI agents for transactions (a “token economy”), Anthropic has developed a system that acts structurally similar to a currency — where transactions are settled in real-time, backed by physical infrastructure.

But here’s the critical insight:

And that gap? It’s where the next $100 million in AI infrastructure value will be captured.

API Credits Are Proto-Stablecoins (Whether They Know It or Not)

Anthropic’s API runs on a prepaid credit system. Developers load accounts with dollars, receive credits, and burn them with each API call. The mechanics are strikingly similar to stablecoin infrastructure:

• Medium of exchange: Credits transfer value between parties (developer → Anthropic → compute provider)
• Unit of account: Priced in USD equivalents, stable against volatility
• Store of value: Balances held for future consumption (though with a 1-year expiration — more on that later)

This is a closed-loop token economy operating at massive scale. Anthropic’s revenue run-rate hit $5 billion in early 2025. That’s not just API sales:

But there’s a problem — a big one. It’s not that Anthropic overlooked it — they are a model company and weren’t even looking.

But the problem remains: Anthropic’s “tokens” are trapped in legacy payment rails:

• Credit cards
• ACH transfers
• Manual invoicing for enterprises spending $1,000+/month
• Prepaid balances that expire after 12 months if unused, creating breakage and float inefficiencies

The system works, but the contradiction is:

Where the Machine Economy Breaks Down

The friction points in Anthropic’s current payment infrastructure aren’t just operational inconveniences — they’re architectural constraints on the entire AI agent ecosystem:

1. Prepaid Prison

Developers must forecast consumption and lock up capital in advance. For AI agents making autonomous decisions — hiring other agents, purchasing compute, negotiating services — this is a non-starter. Agents need just-in-time liquidity — not prepaid prison.

2. No Native Agent-to-Agent Settlement

Anthropic’s API enables agents to consume intelligence. But there’s no protocol for agents to pay each other using the same rails. The “token economy” stops at Anthropic’s door. Inter-agent commerce — the real machine economy — happens elsewhere, if at all. While emerging standards like x402 define how agents request payment, they still require a settlement backend to execute the transfer — a gap Exe’s paymaster infrastructure fills.

3. Legacy Settlement Velocity

Credit card settlement takes days. ACH takes longer. In a world where AI agents make decisions in milliseconds, waiting for traditional financial infrastructure is like running a Formula 1 race on a dirt track.

4. Policy Vacuum

Anthropic emphasizes AI safety, constitutional AI, and trust. But their payment infrastructure has no equivalent safety layer:

• No programmable spending limits
• No policy-governed autonomy
• Just manual spend caps and post-hoc billing surprises

To reiterate: this isn’t a critique of Anthropic — they’re a model company, not a financial infrastructure company.

But it does represent a massive untapped opportunity — for both Anthropic and whoever builds what they’re missing.

The Missing Layer: Settlement Infrastructure for Autonomous Agents

What Anthropic needs — and what the broader AI agent ecosystem requires at scale— is a settlement layer designed for machine-native commerce:
not just payments. Settlement. Final, irreversible, programmatic value transfer between autonomous systems.

This is where Solana becomes critical.

While Anthropic’s API credits function as theoretical stablecoins, Solana provides the actual settlement infrastructure:

• 24/7 uptime: No banking hours for AI agents
• Sub-second finality: Transactions confirmed faster than API response times
• <$0.0001 per transaction: Micropayments viable at scale
• 65,000+ TPS: Throughput matching AI agent velocity

But raw blockchain infrastructure isn’t enough. The missing piece is a policy-governed paymaster—a smart contract-based payment agent that enables autonomous systems to spend within programmable guardrails.

Think of it as “constitutional AI” for money. Just as Anthropic’s models follow constitutional principles, a policy-governed paymaster follows financial constraints:

• Maximum spend per transaction
• Whitelist/blacklist capabilities
• Time-based limits
• Multi-signature requirements for large transfers

Enter Exe Protocol: Economic Infrastructure for AI Agents

Exe Protocol builds exactly this missing layer.

Our policy-governed Exe Paymaster contract validates/spends for multiple agents via policy IDs. This enables AI agents to become economically self-sustaining — not by burning subsidies, but by capturing value through transaction spreads and basis points, determined by the data they generate.

The mechanics are simple but powerful:

• Agents hold USDC in self-custodial wallets, called “Execution Vaults” (EVs)
• Paymaster contracts enforce spending policies (set by developers, not black-box algorithms)
• Real-time settlement on Solana eliminates counterparty risk and float requirements
• Agents capture 8–20% spreads on transactions they facilitate, creating sustainable economics

The result:

Our infrastructure integrates seamlessly with Anthropic’s ecosystem, completing the financial system they accidentally started.

Menlo’s Anthology Fund Already Sees the Gap

In Q3 2025, the Anthology Fund — a $100 million initiative backed by Menlo Ventures and Anthropic — made an investment in “AI payments infrastructure.”

They recognize the gap.

They’re actively deploying capital to fill it.

But:

Payments are about user interfaces and checkout flows.

Settlement is about the underlying value transfer infrastructure — the digital rails for M2M commerce.

The Anthology Fund’s investment thesis centers on five areas:

• AI infrastructure
• Vertical AI
• AI-first applications
• AI safety and trust
• Frontier research

Our policy-governed paymaster sits at the intersection of AI infrastructure and AI safety and trust — programmable financial guardrails for autonomous systems.

The strategic fit is precise:

• Anthropic provides the intelligence layer (Claude)
• Exe provides the economic layer (settlement)

Together, they enable truly autonomous AI agents that are both capable and economically self-sustaining

This isn’t about competing with Anthropic’s API credit system. It’s about extending it — unlocking liquidity, enabling inter-agent commerce, and providing the settlement infrastructure that makes their token economy actually function like an economy.

The $33 Trillion Opportunity

To understand the scale of this opportunity, consider stablecoin settlement volumes: $33 trillion in 2025. AI agent payments currently represent just 0.0001% of that volume. Many analysts project machine customers could account for 20% of revenue by 2030.

We’re at the inflection point. The infrastructure is maturing. The use cases are emerging. And Anthropic — with its $5 billion run-rate and massive developer ecosystem — is the gravitational center of the agentic economy.

But economies need settlement layers. Without them, tokens are trapped in prepaid accounts, there’s friction in every transaction, and autonomous agents can’t actually transact autonomously.

Exe completes the picture:

Conclusion: Building the Economic OS for AI

The future of AI isn’t just smarter models. It’s economically autonomous agents that can hire, purchase, invest, and transact without human intermediation at every step.

Anthropic built the intelligence infrastructure for this future. We’re building the economic infrastructure:

• A policy-governed paymaster
• Real-time settlement
• Programmable financial guardrails

In short, the missing layer that turns API credits into actual currency, and AI agents into actual economic participants.

If Anthropic is building the brain, we’re building the wallet — and the bank, the exchange, and the regulatory framework.
