[Polygon Launches On-Chain Toolkit Agent CLI for AI Agents] According to the Polygon Labs blog, Polygon Labs has launched Polygon Agent CLI, a one-stop on-chain infrastructure solution for AI agents, providing wallet, payment, cross-chain, and identity functionalities. Developers can install it with a single command, enabling agents to create session wallets, query multi-chain balances, send stablecoins, perform swaps and cross-chain transactions, access DeFi, and register on-chain identities via the ERC-8004 standard to accumulate reputation. The toolkit features built-in gas abstraction, with all operations settled in stablecoins like USDC, eliminating the need to hold native gas tokens. Private keys are kept out of the LLM context to reduce prompt injection risks, and each transaction is previewed with a default dry run. Agent CLI is already compatible with mainstream agent frameworks such as Claude and Openclaw.
