Chrome Extension

The Yativo Crypto Chrome extension adds a persistent toolbar button that gives you instant access to your wallets, cards, swap, and deposit notifications — powered by Manifest v3 and a background service worker.

​
Installation

  1. Open the Chrome Web Store and search for “Yativo Crypto”, or follow the direct link provided in your Yativo dashboard.
  2. Click “Add to Chrome”.
  3. When prompted, click “Add extension” to confirm.
  4. The Yativo icon appears in your Chrome toolbar. If it is hidden, click the puzzle piece icon and pin Yativo.
The extension is compatible with Chrome 88+ and all Chromium-based browsers including Brave, Edge, and Arc.

​
Initial Setup

  1. Click the Yativo toolbar icon to open the popup.
  2. You will see the Setup screen on first launch.
  3. Enter your API Key and API Secret from the Yativo dashboard.
  4. Click Save & Connect.
The extension verifies your credentials against the Yativo API. If valid, the popup switches to the main dashboard view.
Generate a dedicated API key for the extension with limited permissions (e.g. wallets:read, transactions:read, cards:read, swap:write). This reduces risk if the credentials are ever exposed.

​
Features

​
1. Wallet Monitoring

Once connected, the popup’s Wallets tab lists all wallets associated with your Yativo account, including:
  • Asset type and network
  • Current balance
  • Deposit address (click to copy)
Balances are refreshed each time the popup is opened. Use the Refresh button to force an immediate update.

​
2. Real-Time Deposit Notifications

The extension registers a service worker (Manifest v3) that polls the Yativo API every 30 seconds using Chrome’s chrome.alarms API. When a new deposit is detected:
  1. A browser notification fires immediately with the deposit amount, asset, and destination wallet.
  2. Clicking the notification opens the Yativo popup focused on the relevant wallet.

​
Notification Settings

Open the popup → Settings tab to configure:
SettingDescription
Enable notificationsToggle deposit polling on/off
Poll interval30 seconds (fixed; respects Chrome alarm minimum)
Minimum deposit thresholdOnly notify for deposits above a set amount
Sound alertsPlay a chime when a notification fires
Chrome may throttle service workers for inactive tabs. Deposit detection typically occurs within 30–60 seconds of the on-chain confirmation.

​
3. Auto-Forwarding Management

The Auto-Forward tab lets you view, create, and delete auto-forwarding rules without opening the full dashboard. Creating a rule:
  1. Click + New Rule.
  2. Select the source wallet.
  3. Enter a destination address.
  4. Set the forwarding percentage (1–100%).
  5. Click Save Rule.
Disabling a rule: Toggle the switch next to any existing rule, or click Delete to remove it permanently.

​
4. Yativo Card Management

The Cards tab displays your virtual cards. For each card you can:
  • View the card label, last 4 digits, and expiry
  • Check the current card balance
  • See recent card transactions (last 10)
  • Freeze or Unfreeze a card with one click
  • Copy the card funding address to top up the card balance

​
5. Price Alerts (SOL and XDC)

The Alerts tab lets you set price thresholds for SOL and XDC:
  1. Select the asset (SOL or XDC).
  2. Choose Above or Below.
  3. Enter the price target in USD.
  4. Click Set Alert.
The background service worker checks prices on each polling cycle. When the threshold is crossed, a browser notification fires and the alert is automatically cleared. You can have multiple active alerts per asset. Alerts are stored in chrome.storage.local.

​
6. Swap Functionality

The Swap tab provides a quick-access swap interface:
  1. Select From asset and To asset.
  2. Enter the amount.
  3. Click Get Quote — the extension calls the Yativo Swap API and displays the estimated output and fee.
  4. Click Execute to confirm. The transaction is submitted immediately.
Swap quotes expire after approximately 30 seconds. If the quote expires before you click Execute, fetch a new one.

​
7. Standalone IBAN Management

The IBAN tab lists all standalone IBAN accounts linked to your Yativo account:
  • IBAN number (click to copy)
  • BIC/SWIFT code
  • Currency and label

How Notifications Work

Background Service Worker
    │
    ├─ chrome.alarms.create("yativo-poll", { periodInMinutes: 0.5 })
    │
    └─ Every 30 seconds:
         ├─ Fetch latest deposits via Yativo API
         ├─ Compare against last-seen deposit IDs in chrome.storage.local
         ├─ For each new deposit → chrome.notifications.create(...)
         └─ Update stored deposit IDs
Notifications require the notifications permission (declared in manifest.json). Chrome will prompt for this permission on first use.

​
Security

ConcernHow it is handled
Credential storageStored in chrome.storage.local — isolated to the extension’s sandbox
Data in transitAll API calls use HTTPS to https://crypto-api.yativo.com/api/
No third partiesThe extension communicates only with crypto-api.yativo.com
Minimal permissionsstorage, notifications, alarms — no broad host permissions
Manifest v3Uses service workers instead of persistent background pages for better security and performance

​
Troubleshooting

Symptoms: “Invalid credentials” or spinner never stops.Steps:
  1. Verify your API key and secret in the Yativo dashboard — make sure they have not been revoked.
  2. Check that the key has at least wallets:read permission.
  3. Open chrome://extensions, find Yativo, and click Details → Extension errors to see any console errors.
  4. Re-enter your credentials in the extension settings.

​
