AgentCash creates and manages a local wallet that holds USDC for paying premium APIs. The wallet is created automatically the first time you use AgentCash.

​
Where is the wallet stored?

Your keys live under ~/.agentcash/ with restricted file permissions (600):
  • wallet.json: EVM keypair (covers Base and Tempo)
  • solana-wallet.json: Solana keypair
Each file contains a private key, its address, and a creation timestamp.
Private keys are stored in plaintext on disk. Do not share these files or commit them to version control. Anyone with the keys can spend your USDC.

​
Using an existing key

To use specific private keys, set environment variables:
Either variable can be set independently. You can choose to omit one if you don’t want to use that chain. Useful for CI/CD environments or when you want multiple machines to share a wallet.

​
Checking your balance

Ask your agent:
What is my AgentCash balance?
Or use the CLI directly:
This returns your total USDC balance across supported networks. If you need deposit links or network-specific wallet addresses, run:
This returns the per-network account list, including each address, balance, and deposit link.

​
Wallet addresses

Your wallet exposes two addresses:
  • A single EVM address that receives USDC on every supported EVM network (Base, Tempo).
  • A separate Solana address for USDC on Solana.
Run npx agentcash accounts to see each one along with its current balance and deposit link. See networks for the full list.
