# Sending Coins

Send coins to any collector using their email address or wallet address. There are no gas fees — Numex covers transaction costs.

## How It Works

```mermaid
sequenceDiagram
    participant You
    participant Numex
    participant Recipient

    You->>Numex: "Send coin to alice@example.com"
    Numex->>Numex: Resolve email to wallet
    Numex-->>You: Confirm recipient
    You->>Numex: Confirm send
    Numex->>Recipient: Coin transferred
    Numex-->>You: Sent!
```

1. Go to a coin in your **Portfolio**
2. Click **Send**
3. Enter the recipient's **email** or **wallet address**
4. Confirm — the coin moves to their portfolio instantly

## Send by Email

You can send a coin to anyone by email, even if they haven't signed up yet:

* If they have a Numex account, the coin appears in their portfolio immediately
* If they're new, a wallet is reserved for their email — when they sign in, the coin will be waiting

## No Gas Fees

You never pay gas fees on Numex. All transaction costs are covered by the platform. Sending a coin is free for both the sender and recipient.

## Send by Wallet Address

If you know the recipient's wallet address (starts with `0x`), you can send directly to it. This works with any Ethereum-compatible wallet on Base.
