Polygon Unveils CLI Toolkit Enabling AI Agents to Transact On-Chain

• Polygon has published a CLI kit that gives AI agents access to wallets, payments, swaps, bridging, onchain identity, and more.
• Founder Sandeep Nailwal says that the kit is like giving agents their own Open Money Stack.

Polygon has joined the growing list of blockchain networks releasing new tools targeting AI agents, publishing a new CLI kit that lets these agents interact with its network directly.

The Polygon Agent CLI is described as a unified tool “for everything an agent needs to go onchain.” It enables an agent to hold and move money on the network, and pay for services onchain without needing any human intervention.

Founder Sandeep Nailwal, who now leads the Polygon Foundation, described the toolkit as everything an agent would need to go on-chain, adding, “We literally just gave agents their own Open Money Stack.”

Nailwal says that the AI agent economy can only function if these agents have access to real financial rails, enabling real identity and payments.

Polygon joins Injective, which, earlier this week, launched a similar CLI toolkit that allows agents to interact with its network directly from the terminal. As CNF reported, Injective is targeting developers building dApps and automation tools on the network so they do not have to stop and search for commands on routine blockchain tasks.

Autonomous AI Agents on Polygon

Previously, deploying an AI agent on Polygon required developers to integrate several tools to access bridges, swaps, wallets, payment rails, identity systems and other functionalities. The new CLI kit comes with all these tools built in.

Agents that integrate the kit can create and manage wallets, send tokens to other agents, swap assets, bridge funds across chains, check transaction history and register their own on-chain identity.

They can also automatically pay for data services or APIs, which is vital for AI agents as they require data to run, and this data is sometimes stored behind a paywall. This is made possible by the inclusion of the x402 protocol, which lets these APIs and services charge money directly through HTTP requests.

x402 was designed by Coinbase and Cloudflare, but has since become an open industry standard. As CNF reported, Algorand recently joined the x402 ecosystem via GoPlausible, a payments processor on its network. Solana is one of the networks where the standard is most widely used, with the network processing over $600,000 daily at some point.

Notably, Polygon’s new CLI kit allows all gas fees to be paid in stablecoins, with no POL required. However, gas fees on Polygon can only be paid for in POL, so the toolkit likely converts the USDC or USDT to POL in the background. By only requiring the agents to hold stablecoins, the toolkit eases the burden of volatility.

Other networks have released new features for AI agents this year as the two technologies continue to merge. BNB Chain now enables AI agents to execute actions directly from messaging apps through Pieverse’s Purr-Fect Claw, while Sui and Hedera have published new materials on why their networks are most suited for agentic commerce.
