Environment variables
  • AGENT_KEYsecretHex private key of an EVM wallet funded with USDC on any EVM rail the server offers (Base, Polygon, Arbitrum, Monad, Celo, Avalanche, Sei, Optimism, Arc, Ink) or USDG on Robinhood Chain; use SOLANA_AGENT_KEY for Solana. Stellar and Algorand are not signed by this package. Unset = proof-of-work mode (free pure-CPU tools).
  • AGENT402_CREDITS_KEYsecretPrepaid credits key (a402_...) for Agent402's own services. With it set and no wallet key, every tool except the wallet-scoped ones (memory, usage) and the outside-seller routes (router.execute, seller-payability, decide.execute, the flight tools) is debited from the key; the list price is debited only on a successful call.
  • SOLANA_AGENT_KEYsecretOptional base58 (or JSON byte-array) secret key of a Solana wallet funded with USDC on Solana.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.
