# Send Tokens

> Send native tokens or ERC-20 tokens to an address, ENS name, basename, or cb.id using Base MCP

## What you can ask

```text theme={null}
Send 10 USDC to alice.base.eth
```

```text theme={null}
Transfer 0.01 ETH to 0x1234...abcd
```

```text theme={null}
Pay bob.eth 5 USDC
```

```text theme={null}
Send 50 DEGEN to vitalik.eth
```

## How it works

The `send` tool constructs a transfer and requires your approval in Base Account. Nothing is sent until you confirm.

| Parameter   | Required                    | What it does                                                                                                          |
| ----------- | --------------------------- | --------------------------------------------------------------------------------------------------------------------- |
| `recipient` | Yes                         | Address, ENS name, basename (e.g. `alice.base.eth`), or cb.id name                                                    |
| `amount`    | Yes                         | Human-readable decimal (e.g. `"10.5"`)                                                                                |
| `asset`     | Yes                         | Known symbol (`ETH`, `USDC`, `POL`, `AVAX`, `BNB`) or ERC-20 contract address                                         |
| `chain`     | Yes                         | Network to send on, e.g. `base`, `base-sepolia`, `ethereum`, `arbitrum`, `optimism`, `polygon`, `bsc`, or `avalanche` |
| `decimals`  | When using contract address | Required when `asset` is a contract address                                                                           |

<Tip>
  For known assets like ETH, USDC, POL, AVAX, and BNB, just use the symbol — no contract address needed. For less common tokens, your assistant will call `search_tokens` first to resolve the address and decimals automatically.

## Approval flow

Every send requires a manual approval:

<Steps>
  <Step title="Your assistant calls send()">
    The transaction is constructed but not yet broadcast.
  </Step>

  <Step title="You receive an approval link">
    Open the approval link to review the recipient, amount, and fee in Base Account.
  </Step>

  <Step title="You approve">
    Confirm the transaction in the approval UI. Nothing is sent without your explicit confirmation.
  </Step>

  <Step title="Transaction confirms">
    Your assistant polls `get_request_status` and reports success once the transaction is confirmed onchain.
  </Step>
</Steps>
