Stronghold

Funding Your Account

Stronghold requires USDC in your wallet to pay for scans. There are two ways to fund your account.

Visit the dashboard to fund your wallet through a web interface. The dashboard supports:

  • Stripe — pay with a credit or debit card (fiat-to-USDC on-ramp)

The Stripe integration converts your payment into USDC and delivers it to your wallet on-chain. This is not a separate payment method — all API payments still use x402. Stripe only handles the initial funding step.

Note: Stripe requires a linked wallet address (Base or Solana) before you can initiate a purchase. Link your wallet via the dashboard or with stronghold wallet link before depositing.

Option 2: Direct USDC Transfer

Send USDC directly to your wallet address on Base (EVM) or Solana. Direct transfers are detected and credited automatically after blockchain confirmation.

To view your deposit addresses, run stronghold account deposit. This displays your Base (EVM) and Solana wallet addresses (if configured) along with instructions:

Terminal window
stronghold account deposit

Checking Your Balance

Use the CLI to check your balance across all configured wallets:

Terminal window
stronghold account balance

Output shows per-chain balances:

Base (EVM) Wallet:
  0x1234...5678
  Balance: 4.500000 USDC


Solana Wallet:
  ABC123...XYZ
  Balance: 2.000000 USDC

Low Balance Warning

The web dashboard displays a warning when your wallet balance drops below 1 USDC. At $0.001 per scan, 1 USDC covers approximately 1,000 requests — so this warning gives you time to top up before running out.
