# FAQ & Safety

### Frequently asked questions

<details>

<summary>What is p2p.gifts?</summary>

p2p.gifts is a browser-only **P2P crypto gifting wizard** built on the [mybucks.online](https://mybucks.online) **digital cash envelope** (seedless, disposable wallet) framework. You create a one-time wallet, fund it, and share a branded gift card with a QR code. The receiver scans and claims — no signup, no app install on either side.

</details>

<details>

<summary>Which networks are supported?</summary>

Ethereum, Polygon, Arbitrum, Optimism, BNB Chain, Avalanche, Base, and Monad.

</details>

<details>

<summary>Can I send any token?</summary>

You can send any native coin or ERC-20 token on the supported networks. When the receiver claims on [app.mybucks.online](https://app.mybucks.online), token balances are filtered based on the [Uniswap default token list](https://tokenlists.org) to prevent scam or fake tokens from appearing. Just make sure to include some native tokens for gas so the receiver can claim.

</details>

<details>

<summary>Should I use the auto-generated passphrase and PIN?</summary>

**Yes — that is the recommended default.** When you open the create-wallet step, p2p.gifts auto-fills a random passphrase and PIN that meet strength requirements. Tap the refresh icon beside either field to generate a new random value.

You *can* edit the credentials, but we **strongly encourage keeping the auto-generated values** (or refreshing until you are happy with them). Do not reuse passwords from email, banking, or your main crypto wallet. Gift wallets are one-time and unguarded — weak or memorable credentials are easier to guess.

If you choose custom values, they must still pass the on-screen strength meter before you can create the wallet.

</details>

<details>

<summary>Does p2p.gifts store my passphrase or PIN?</summary>

No. The passphrase and PIN exist only in your browser tab while the page is open. Nothing is sent to a server or saved in local storage.

</details>

<details>

<summary>What if I close the browser before saving the gift card?</summary>

The passphrase and PIN are lost. There is no recovery. Always download the gift card or copy the gifting link before closing the page.

</details>

<details>

<summary>Can I reuse a gift wallet?</summary>

Technically yes — if you kept the passphrase and PIN, you can access it again through [app.mybucks.online](https://app.mybucks.online). But gift wallets are designed to be disposable: create, fund, gift, done.

</details>

<details>

<summary>Is there a limit on how much I can send?</summary>

No technical limit, but p2p.gifts is designed for **micro-gifts**. Do not fund gift wallets with large amounts.

</details>

<details>

<summary>Can I customise the gift card?</summary>

Yes. You can choose from built-in themes, upload a custom background image, and add a gift note with Markdown formatting (bold, italic, headings, line breaks).

</details>

<details>

<summary>How does the receiver claim?</summary>

They scan the QR code or open the gifting link, which takes them to [app.mybucks.online](https://app.mybucks.online). From there they can view the balance and transfer funds to their own wallet.

</details>

<details>

<summary>Is p2p.gifts open source?</summary>

Yes — [github.com/mybucks-online/p2p.gifts](https://github.com/mybucks-online/p2p.gifts), [MIT licensed](/p2p.gifts/license.md).

</details>

### Safety guidelines

1. **Save before you close.** Download the gift card PNG or copy the gifting link before closing or refreshing the page. There is no undo.
2. **Use strong, random credentials.** Keep the auto-filled passphrase and PIN, or use the refresh control to generate new ones. Avoid personal passwords, short PINs, or easy-to-guess phrases — gift wallets are one-time and unguarded.
3. **Treat the gift card like cash.** Anyone who has the QR code or gifting link can access the wallet. Share it privately — DM, email, or in person.
4. **Keep amounts small.** This is built for micro-gifts, not large transfers.
5. **Include gas tokens.** When sending ERC-20 tokens, also send a small amount of native tokens (ETH, MATIC, BNB, etc.) so the receiver can pay transaction fees when claiming.
6. **Tell the receiver to claim promptly.** The wallet is unguarded — first person to scan the QR gets the funds.
7. **Don't post gift cards publicly.** Bots and strangers will sweep the wallet before your intended recipient sees it.
