# Deposit USDC to fund your Raziel account balance

> Fund your Raziel account by sending USDC on Solana to the deposit wallet. Include your unique deposit memo and credits appear within ~60 seconds.

Raziel balances are denominated in USDC on Solana. There are no credit cards, no invoices, and no subscription tiers — send USDC, use the gateway, top up when needed.

<Warning>
  You need a minimum balance of \$0.05 USDC before the gateway will forward your requests. Requests made below this threshold return `HTTP 402 auth_error`.
</Warning>

## How to deposit

<Steps>
  <Step title="Find your deposit memo">
    Sign in and navigate to **Customer → Deposit**. Your account has a unique 16-character `deposit_memo` shown on that page. You will need it in every transaction.
  </Step>

  <Step title="Send USDC to the Raziel deposit wallet">
    Send any amount of USDC (Solana SPL) to the Raziel deposit wallet address shown on the deposit page. Include your `deposit_memo` as an SPL memo in the transaction.

    A QR code is available on the deposit page if your wallet supports scanning.
  </Step>

  <Step title="Wait for confirmation">
    The indexer monitors the Solana chain and credits your account within approximately 60 seconds of transaction confirmation. Your balance updates on the dashboard automatically.
  </Step>
</Steps>

<Note>
  Always include your `deposit_memo` in the SPL memo field. Without it, the indexer has no way to attribute the transaction to your account and your balance will not be updated.
</Note>

## Check your balance

Your current balance is shown on the dashboard and on the **Customer → Deposit** page. It updates after every request — usage is metered per token and deducted in real time.

## How the 15% margin works

Raziel takes 15% at deposit time. If you send $10.00 USDC, $8.50 is added to your spendable balance. The remainder covers the protocol margin. From that point on, requests are charged at OpenRouter rates with no additional markup.

## Top up any time

There is no minimum deposit amount and no expiry on credits. Top up in small increments as you go, or add a larger amount upfront — whichever fits your workflow.
