Which blockchain network should an AI agent use to get paid?

The three things that decide the network

The right blockchain network for your payments is not a technology choice—it is the intersection of three practical constraints. A network that excels on one dimension but fails on another will cost you sales or expose you to risk.

1. Buyer reach—where your buyers already hold funds. A network your buyer cannot easily access costs the sale. If no buyer on your target market can send you value on a given chain, it does not matter how cheap or fast it is.
2. Cost—the transaction fee as a share of your price. For small payments a large fixed fee can eliminate your margin entirely, while for a large payment the same fee can be a rounding error. The same network can be well-suited to one and ruinous for the other, so weigh the fee against the size of the payments you actually expect.
3. Finality and speed—how quickly a transfer confirms and what "confirmed" actually means. An autonomous agent that pays for a service and then waits still needs the payment to settle promptly so it can deliver. Some networks confirm in seconds; others in minutes. Some are probabilistically final; others guarantee it.

The trade-offs, in plain terms

The pragmatic default for small payments

For most agents handling small, frequent payments today, a low-fee network with broad wallet support—major Ethereum layer-2 networks are a commonly observed choice among builders—is a reasonable starting point. Fees on such networks are typically cents rather than dollars, and most major wallet software supports them. This is not a universal recommendation; it is an observation about what many practitioners choose. You should match the network to your actual buyers. If your buyers cluster on a different network, or if your prices are large enough that fees are a rounding error, a different choice may be better.

Why USDC specifically

USDC is a commonly used stablecoin for agent payments because it is issued natively on many blockchains and is widely supported by wallet software and payment facilitators. This is an observation about current tooling, not a guarantee that it will remain dominant or that you must use it. Before you decide on USDC, confirm with your counterparty and payment facilitator what assets they actually support. Some may require a different stablecoin, or may charge different fees for different assets. Your facilitator's constraints are your constraints.

One asset, several networks—do not confuse them

USDC on one blockchain is a different, non-interchangeable token from USDC on another blockchain. Each lives at a different contract address on its own chain. If you receive an address and send USDC to it on the wrong network, the transfer is usually unrecoverable—your buyer cannot retrieve the funds, and neither can you. You must always name the blockchain network alongside the receiving address. When you give an address to a buyer or publish one on your site, label it clearly with the network: "USDC on Base" or "USDC on Polygon" or "USDC on Ethereum mainnet"—every time. Confusion about this is the most common cause of lost funds in agent payments. The guide on how an agent obtains a wallet explains how to generate separate addresses on different networks.

Should you support more than one network?

Support only the networks your buyers actually use. Each additional blockchain rail adds complexity: another address to secure, another balance to reconcile, another opportunity to send funds to the wrong place. Start with the single network most of your buyers use. Add a second network only when a real buyer tells you they cannot use the first one. Running ten networks to capture a handful of outliers is not pragmatism; it is overhead.

Verify before you rely on any of this

• Confirm the current USDC contract address for the network you choose. Official issuer websites and block explorers are authoritative; never trust a secondhand reference.
• Test a small transfer in and back out before you announce an address to buyers. This proves your address is correct and gives you confidence in the network.
• Confirm that your payment verifier or facilitator actually supports that network. An EVM-based verifier will not read a non-EVM chain. A centralized exchange may not support a low-volume layer-2.
• Watch for finality, not just block inclusion. A transaction in a block is not the same as irreversible settlement. Understand the finality model of the network you choose.
