AxLabs Unveils Simple Agent Wallet for Autonomous AI Payments Across Multiple Blockchains
AxLabs has released its Simple Agent Wallet (SAW), a command-line wallet designed for AI agents to autonomously pay for resources across multiple blockchains. The open-source tool, now at v0.3.1, enables agents to inspect and execute payments without human intervention.
Traditional crypto wallets assume a human is present, with browser extensions that open popups and mobile apps that require a tap to confirm. SAW addresses this by providing a wallet built entirely around CLI workflows and scriptable payment flows.
The wallet's core workflow follows an inspect-then-pay pattern: saw inspect decodes an HTTP 402 payment requirement so an agent can evaluate the cost and terms, then saw pay --confirm signs and executes the transaction. Private keys are stored locally in a permissions-locked wallet file, and secrets are accepted only through stdin or environment variables.
SAW manages three blockchain families from one configuration file: EVM chains (including Neo X, Ethereum, Polygon, and others), Solana, and Hedera. The saw init wizard walks through wallet creation or import for each family, while commands like saw balance and saw transfer operate across all three.
