How do I fund my AI agent with USDC?

Send USDC on Solana to the wallet_address your agent reads from GET /getAgentWallet, or USDC on Base to its base_wallet_address. Both addresses feed one balance, and the same call reports when the deposit has landed. Never send funds to the agent’s user_id: a usr_... value is an account id, not an address.

​
Step 1: Get the funding addresses

The agent signs in, announces its connection, and reads its wallet. The sign-in steps are in the managed agent wallet guide.
If has_wallet is false, the human finishes wallet setup at laso.finance/agent/dashboard first. Reference: GET /getAgentWallet.

​
Step 2: Send USDC

Send from any wallet or exchange that can withdraw USDC on the right network: Both land in the same balance_usdc. Use the network that is cheapest for you. A deposit on one network is not stranded there: when a payment needs funds on the other side, Laso moves them first. See One balance on Solana and Base. At least $5 covers a first prepaid card order, with a little headroom for the paid endpoints the agent calls along the way.

​
Step 3: Confirm the deposit landed

Call GET /getAgentWallet again. balance_usdc rises and needs_funding turns false.
To react without polling, register a webhook with POST /register-webhook. Wallet deposits arrive as notification.deposit deliveries. See Agent webhooks.

​
Other ways to fund an agent

  • Bank transfer. A virtual US bank account with ACH and wire details converts dollars to USDC in the managed wallet. See Agent bank accounts.
  • A wallet you already control. If your agent pays from its own wallet, fund that wallet directly. See Wallet providers.

​
Check balances after the agent spends

Call GET /get-account-balance. Paid requests move USDC from the wallet to Laso, so the account balance often reads 0 after a purchase while total_deposits has grown. Funds still held are agent_wallet.balance_usdc plus balance. Reference: GET /get-account-balance. To pull leftover USDC back out, see How do I get USDC back out of my AI agent’s account?.

FAQ

​
What do I send to fund an AI agent’s wallet?

USDC on Solana to wallet_address, or USDC on Base to base_wallet_address, both from GET /getAgentWallet.

​
Can I fund my agent from a bank account?

Yes. Open a banking profile and an on-ramp account, and dollars sent by ACH or wire arrive as USDC in the managed wallet. See Agent bank accounts.

​
Why can’t I send funds to my agent’s user id?

The user_id is an opaque account id that exists on no blockchain. USDC sent to it is lost, so only use the two wallet addresses.

​
How much USDC does an agent need to start?

$5 covers a first prepaid card order. The agent can only spend within the per-payment limit its owner sets, which you can read in Spend limit.

​
How do I know my agent’s deposit arrived?

Poll GET /getAgentWallet until balance_usdc rises, or register a webhook and wait for a notification.deposit delivery.
