# Recuperar Tokens Enviados a la Cadena Incorrecta

> Guía paso a paso para recuperar tokens nativos y personalizados enviados a la cadena incorrecta usando Blockradar Asset Recovery.

If you've ever sent tokens to the correct address but on the wrong blockchain, you know that gut-drop moment when it feels like your funds have vanished. With Blockradar Asset Recovery, getting your tokens back is possible and simpler than you might think.

With Blockradar Asset Recovery, you can:

* Recover native tokens on all supported blockchains
* Recover custom tokens (ERC-20 and other compatible assets) on supported networks
* Recover tokens on unsupported or custom networks by providing your own RPC endpoint
* Recover tokens on Layer 2 networks (Arbitrum, Optimism, Base, and other EVM-compatible rollups)

***

## Prerequisites

Before starting a recovery, have the following information ready:

| Field                      | Description                                                                               |
| -------------------------- | ----------------------------------------------------------------------------------------- |
| **Recovery Blockchain**    | The blockchain where the lost tokens currently reside (e.g. Ethereum, BNB Chain, Polygon) |
| **Token Contract Address** | Required only for custom (non-native) tokens                                              |
| **Recover From Address**   | The Blockradar address that accidentally received the tokens                              |
| **Recover To Address**     | The address where recovered assets should be sent                                         |

***

## Recovering via the Dashboard

### Step 1: Retrieve Transaction Information

If you're missing any recovery details, look up your **transaction hash** on the relevant blockchain explorer and note:

* The blockchain network used
* The receiving address (your Blockradar address)
* The token contract address (for custom tokens)
* The amount transferred

### Step 2: Fill in Recovery Details

On your Blockradar dashboard, navigate to **Asset Recovery** and fill in the required fields.

**For native tokens:**

**For custom tokens:**

<Tip>
  Ensure your wallet has enough native token balance to cover gas fees for the recovery transaction.
</Tip>

### Step 3: Submit Recovery

1. Click **Recover Assets**
2. Enter the OTP from your authenticator app
3. Confirm the action

Once completed, verify the recovery by checking the destination address in your dashboard or searching the transaction hash on the block explorer for the selected chain.

## Recovering via a Custom RPC or Layer 2 Chain

If your lost assets exist on a blockchain not officially supported by Blockradar, you can recover them using a custom RPC URL.

**Additional prerequisites:**

| Field               | Description                                                                                                                                  |
| ------------------- | -------------------------------------------------------------------------------------------------------------------------------------------- |
| **RPC Endpoint**    | A valid HTTPS RPC URL for the blockchain you're recovering from. Free RPC endpoints are available from [PublicNode](https://publicnode.com). |
| **Layer 2 Network** | Enable this toggle if the RPC URL points to an L2 chain (Arbitrum, Optimism, Base, etc.)                                                     |

**Steps:**

1. Enable **Use Custom RPC**
2. Select the Master Wallet associated with your recovery address
3. Paste your RPC URL
4. Toggle **Layer 2 Network** if applicable
5. Fill in all other fields as described above
6. Click **Recover Assets**, verify OTP, and confirm

## Recovering via the API

You can also recover assets programmatically using the Asset Recovery API — ideal for building custom flows or integrating recovery into backend systems.

### Required Parameters

| Parameter          | Description                                                      |
| ------------------ | ---------------------------------------------------------------- |
| `walletId`         | Your Blockradar master wallet ID                                 |
| `blockchainId`     | The unique ID of the blockchain the transaction was performed on |
| `senderAddress`    | The Blockradar address holding the lost token                    |
| `recipientAddress` | The address to send the recovered token to                       |
| `amount`           | Amount of the token to recover                                   |
| `tokenAddress`     | Smart contract address of the token (custom tokens only)         |
| `rpcUrl`           | RPC endpoint for unsupported networks (optional)                 |
| `isL2`             | Whether the RPC points to a Layer 2 chain (optional)             |

### Step 1: Estimate the Network Fee

Before initiating recovery, estimate the gas cost:

```bash theme={null}
curl --request POST \
  --url "https://api.blockradar.co/v1/wallets/{walletId}/salvage/network-fee" \
  --header "Content-Type: application/json" \
  --header "x-api-key: <api-key>" \
  --data '{
    "amount": "2.5",
    "blockchainId": "<BLOCKCHAIN_ID>",
    "senderAddress": "0xYourBlockradarAddress",
    "recipientAddress": "0xRecipientAddress",
    "tokenAddress": null
  }'
```

**Response:**

```json theme={null}
{
  "data": {
    "balance": "0.1",
    "fee": "0.000021"
  },
  "message": "Salvage network fee fetched successfully",
  "statusCode": 200
}
```

<Tip>
  For custom tokens, include `"tokenAddress": "0xTokenContractAddress"` in the request body.
</Tip>

### Step 2: Execute the Recovery

After confirming the fee and available balance, initiate the recovery:

```bash theme={null}
curl --request POST \
  --url "https://api.blockradar.co/v1/wallets/{walletId}/salvage" \
  --header "Content-Type: application/json" \
  --header "x-api-key: <api-key>" \
  --data '{
    "amount": "2.5",
    "blockchainId": "<BLOCKCHAIN_ID>",
    "senderAddress": "0xYourBlockradarAddress",
    "recipientAddress": "0xRecipientAddress",
    "tokenAddress": null
  }'
```

### Step 3: Monitor Recovery Status

Listen for these webhook events to confirm the outcome:

| Event             | Description                     |
| ----------------- | ------------------------------- |
| `salvage.success` | Recovery completed successfully |
| `salvage.failed`  | Recovery failed                 |

***

## Troubleshooting

If you run into issues, check the following:

* **Wrong wallet ID** — make sure you're using the master wallet ID, not a child address ID
* **Missing token contract address** — required for all custom (non-native) tokens
* **Insufficient gas** — ensure your master wallet has enough native token to cover the recovery fee
* **Custom RPC issues** — verify the RPC URL is a valid HTTPS endpoint and that the L2 toggle matches the chain type

***

## Security Notes

* Blockradar is non-custodial — you control keys and policies
* Every recovery is an on-chain transaction that requires gas on the source chain
* OTP is required for all recovery actions on the dashboard
