Most transactions you don't recognize are spam that someone sent you, or one step of something you did yourself. Open the transaction to see what it did. If crypto left your wallet and you didn't send it, [act now](https://docs.fxwallet.com/wallet/unrecognized-transaction#crypto-left-your-wallet-and-you-didnt-send-it).

## Open the transaction

On the **Wallet** tab, tap the network's own coin, such as ETH on Ethereum: its history lists every transaction of yours on that network. A token's history shows only transfers and swaps of that token, and no approvals. Tap the transaction:

- **Type** says what it did, such as **Swap**, **Approve** or **Contract interaction**.
- **Interacted with** shows the contract or token on the other side. A plain transfer shows **From** and **To** instead.
- For an approval, **Approved amount** and **Approved to** say how much of the token a contract can spend, and which contract.

FxWallet names each action on Ethereum, BNB Chain, Base and some other EVM networks.

## Find what you see

| What you see | What it usually is | What to do |
| --- | --- | --- |
| **Receive**, **Token Receive** or **NFT Receive**, from an address you don't know | Spam | Ignore it. See [Tokens or amounts you didn't ask for](https://docs.fxwallet.com/wallet/unrecognized-transaction#tokens-or-amounts-you-didnt-ask-for). |
| A transfer of 0, of a tiny amount, or of the same amount as one you just sent, to an address that looks like one you use. Often marked **Spam** | Spam made to look like your own transfer. Nothing left your wallet. | Ignore it, and don't copy the address. See [Tokens or amounts you didn't ask for](https://docs.fxwallet.com/wallet/unrecognized-transaction#tokens-or-amounts-you-didnt-ask-for). |
| **Approve**, just before a swap or a DApp action of yours | One step of that action | Nothing. See [One step of something you did](https://docs.fxwallet.com/wallet/unrecognized-transaction#one-step-of-something-you-did). |
| **Contract interaction**, or a type you haven't seen, at a time you were using a DApp | One step of what you did there | Nothing, if the time matches. See [One step of something you did](https://docs.fxwallet.com/wallet/unrecognized-transaction#one-step-of-something-you-did). |
| **EIP7702 Upgrade**, at a time you paid a network fee with a token | The first time you did that on this network | Nothing. See [One step of something you did](https://docs.fxwallet.com/wallet/unrecognized-transaction#one-step-of-something-you-did). |
| **EIP7702 Upgrade**, with an amount you received | A transfer from someone else's upgraded account. Your address wasn't upgraded. | Nothing. See [One step of something you did](https://docs.fxwallet.com/wallet/unrecognized-transaction#one-step-of-something-you-did). |
| **Approve** that you don't remember | Permission for a contract to spend one of your tokens | Revoke it. See [An approval you don't recognize](https://docs.fxwallet.com/wallet/unrecognized-transaction#an-approval-you-dont-recognize). |
| Anything that took crypto or an NFT out of your wallet and that you didn't make: **Send**, **Transfer**, **Swap**, **NFT Send** or another type | Someone else can use your wallet | If it's marked **Spam** and your balance didn't change, it's spam: see [Tokens or amounts you didn't ask for](https://docs.fxwallet.com/wallet/unrecognized-transaction#tokens-or-amounts-you-didnt-ask-for). Otherwise [act now](https://docs.fxwallet.com/wallet/unrecognized-transaction#crypto-left-your-wallet-and-you-didnt-send-it). |

## Tokens or amounts you didn't ask for

A **Receive** or **Token Receive** from an address you don't know is usually spam. Receiving it can't take anything from you. A transfer of 0 that seems to come from you is spam too: anyone can make one appear in your history, and nothing left your wallet.

So is a transfer that repeats one you just made, with the same amount but to an address that only looks like the one you sent to. It moves a worthless token with the same name, and your balance of the real token doesn't change. The **Fee** on it was paid by whoever sent it, not by you.

FxWallet marks the spam it detects as **Spam**, next to the type in your history and on the transaction, and hides it while **Hide Spam Transactions** is on.

Don't open links in the token's name, don't approve anything to "claim" it, and don't copy addresses from your history: scammers send from addresses that look like ones you use. See [Look-alike addresses](https://docs.fxwallet.com/security-and-scams/fake-tokens-and-offline-trading-scams#look-alike-addresses).

## One step of something you did

Some actions take more than one transaction. Compare the time and the tokens involved with what you did then.

- A swap or a DApp often asks for an **Approve** first. Some tokens, such as USDT, can need two.
- A DApp can send more than one transaction for one action. Some show as **Contract interaction**.
- **EIP7702 Upgrade** appears the first time you pay a network fee with a token on that network. It can also appear on crypto you receive from someone else's upgraded account, which doesn't upgrade yours. If it is neither, see [What is the EIP-7702 upgrade?](https://docs.fxwallet.com/wallet/eip-7702#if-fxwallet-says-your-address-was-upgraded-in-another-wallet)

## An approval you don't recognize

If **Approved to** is a contract you don't know, or **Approved amount** is **Unlimited** for an app you no longer use, revoke it in **Wallet** → **More** → **Approvals**. See [Revoke approvals](https://docs.fxwallet.com/wallet/token-approvals#revoke-approvals).

## Crypto left your wallet and you didn't send it

> **Danger**
>
> Someone may have your mnemonic phrase or private key, or used an approval you gave. Create a new wallet on a phone you trust and move your assets to it now. See [What to do if your wallet is compromised](https://docs.fxwallet.com/security-and-scams/if-your-wallet-is-compromised).
