2026 is poised to be the year AI Agents truly emerge as economic participants. These agents are already automating tasks like calling SaaS APIs, executing trades, purchasing cloud resources, and orchestrating workflows. Just as humans rely on credit cards as a “banking channel” for real-world transactions, AI Agents need their own banking system—and I believe it will be built on stablecoins.
This argument breaks down into two parts. First, why crypto (not credit cards) is better suited as the banking infrastructure for Agents. Second, how to build it: Assuming crypto becomes the Agents’ banking layer, what infrastructure is needed to make it work?
Why Crypto Over Credit Cards?
In the crypto community, credit card systems are often dismissed as unsuitable for AI Agents. This view is superficial and likely inaccurate. In fact, traditional payment giants like Visa have made significant strides in Agent commerce. For instance, Visa Intelligent Commerce offers a payment system for AI Agents akin to Apple Pay. Here’s how it works:
- Similar to Apple Pay, it assumes the user already has a credit card.
- Visa issues tokenized credentials for the Agent, with set limits, scopes, and expiration dates. These include a unique virtual card number that users can securely delegate to their Agent.
- When an Agent (e.g., OpenClaw) transacts using these credentials, Visa decrypts the info on its servers, links it to the user’s real credit card, and processes the payment. Crypto isn’t involved at all.
Lobster.cash has demonstrated this full process. In short, Agent credit cards are viable and may even outperform crypto payments in some cases. So why bother with crypto? Three key reasons:
1. More Flexible Trust Structures
Credit card systems—and their Agent virtual card extensions—rely on a rigid trust model. They assume every payment must be backed by a KYC-verified human bank account.
In other words, humans set up the account first, then delegate partial authority to the Agent—like parents issuing a supplementary card to a child.
Crypto and stablecoin payments aren’t bound by this. You can (and often should) link a stablecoin wallet to a KYC’d bank account, like a centralized exchange. But it’s not required. Stablecoin wallets can tie to virtually any identity system, such as:
- Government ID proofs
- Social media accounts (e.g., Google, TikTok, Instagram OAuth)
- Domain name servers
- Headless smart contracts
Many Agents will indeed emerge from fiat-trust systems like Lobster.cash. But others—like Conway—will arise from internet fringes, independent of traditional finance. For them, stablecoins are the only scalable way to handle funds.
As the internet adage goes, “On the internet, nobody knows you’re a dog.” On crypto networks: “Nobody knows you’re a robot.”
2. A Global “Internet-Native Currency”
Stablecoins are a truly global, internet-native currency. For example, Alipay’s integration with Qwen, where AI Agents distribute milk tea vouchers, hints at future Agent commerce. If you’ve lived or traveled in China over the past decade, you’ve experienced this convenience in ecosystems for delivery, ridesharing, payroll, and daily payments. But it’s geographically siloed, enforced by statutory authorities in a closed tech stack.
Stablecoins differ: They’re global from inception, extending this internet-native finance worldwide. This is crucial for AI Agents, whose initial automated workflows will likely involve cross-border SaaS combinations, such as:
- Calling U.S. LLM APIs
- Using European data providers
- Scheduling Southeast Asian compute clusters
Fragmented regional payment systems would be inefficient. Agents need a unified global payment rail.
3. Novel Payment Models
In stablecoin systems, any service interface can become a billable endpoint. This creates a “double Jevons’ paradox” for the internet economy: More entities can transact (anyone or any system can have a wallet), and each participant’s transaction frequency rises sharply.
Why?
- Flexible payment trust structures
- Stablecoins flowing seamlessly across global SaaS workflows
This spawns new payment and revenue-sharing models. For instance, a Dune Dashboard creator could charge stablecoin fees for queries.
How to Build an AI Banking System?
Having covered the “why,” let’s explore how to construct an AI Agent banking system on crypto networks.
Human banks handle storage, settlements, asset growth, and lending, plus basics like identity registration, dispute resolution, and AML compliance. For AI Agents, it’s more than just a wallet—we need comprehensive financial security and governance infrastructure.
This system comprises four core components: identity and authorization, payment liquidity, security mechanisms, and application markets. Blockchain often holds advantages over traditional finance here.
1. Identity and Authorization Systems
First, identity and authorization: Who is the transacting Agent, and whom does it represent? Designs vary:
- Mirror Visa’s model by binding Agent identity to fiat credit cards
- Link wallets to emails or social media accounts
- Register Agent identities directly on-chain
For example, record identities on chains like Ethereum. Standards like ERC-8004 are designed precisely for building Agent registration systems.
2. Payment Liquidity
The second challenge is ensuring Agents can actually pay. Creating a stablecoin wallet doesn’t magically fund it. Many platforms use free credits now, but that’s unsustainable at scale. We need robust mechanisms like:
- Fiat-to-crypto on-ramps
- Pre-funded accounts
- Buy-now-pay-later
- Pre-authorized payments
We must also address blockchain scalability. Current Agent on-chain transactions average ~$0.09. As volumes grow, designs like batching, payment channels, and pre-authorized txns are essential to prevent micro-payments from clogging networks.
3. Security Mechanisms
Like human banks combating money laundering, Agent banks must mitigate new risks: prompt injections, runaway API costs, credential leaks. Fortunately, crypto has amassed tools like trusted execution environments, multi-party computation, multi-signatures, and zero-knowledge proofs.
These can secure Agent payment systems and credential management. In essence, wallet private keys are ultra-sensitive API keys—so the full suite of key protection should apply to Agents’ skills and APIs.
4. Application Markets
Finally, the application layer. We’re in the early days of Agent app store competition.
Platforms like Merit Systems, ATXP, Sponge, and Sapiom are building “skills marketplaces.” Agents can perform tasks like scraping LinkedIn data, sending emails, or trading on Hyperliquid. Whether buying real-world services, paid SaaS APIs, or auto-trading crypto, Agents need discovery and decision-making: Which service to call, which wallet to use, how much to pay. Coinbase’s x402 protocol offers a permissionless way for Agents to access real-world services, enabling them as independent economic actors in the internet economy.
Conclusion
The Agent economy is just dawning. Claude Code and OpenClaw’s popularity exploded less than six months ago. Meanwhile, blockchain has proven it can support a multi-billion-dollar on-chain economy over the past decade. I believe these trends will converge soon. Blockchain and stablecoins will likely become the banking infrastructure for Agents.
The future AI Agent bank won’t look like a bank. It’ll look like: blockchain.
