TONAPI and TON Console

🛠 wallet.ton.org runs on TON API TON Core team becomes the latest customer of our development platform TON API, among @wallet, Trust Wallet, Tonstakers and many other big players in TON. The latest upgrade of wallet.ton.org relies on TON API for its key features: token and NFT balances, and price feeds. We are delighted to support and grow the TON ecosystem with our integrated approach to infrastructure, open standards, partnerships and deep product integration in Tonkeeper, Tonkeeper Pro and Ton Console.

TONAPI for wallet.ton.org Anatoly Makosov published the post about the launch of the updated version of wallet.ton.org. The TONAPI team is honored by the trust placed in them and the recognition from the Core Team for choosing tonapi.io as one of the data sources for the wallet.

We wrote an article to explain in more detail how external-in normalization works and how to use it to track transactions reliably. Read the article

Tracking Transactions on TON Just Got Easier! 🎉 Tracking external transactions (external-in) on the TON blockchain was challenging for all of us due to minor metadata differences. Now TonAPI solves this with the normalized hash. With this method, tracking transactions is simple and reliable. We've prepared clear examples to get you started: - Tracking transactions from TonConnect for dApps - Tracking manually constructed external messages See code examples → We’re excited to share this improvement, and soon more ecosystem tools will support it too!

The Testnet API will undergo planned maintenance on April 4, 2025, from 08:00 UTC to 12:00 UTC. It will be unavailable during this time.

Get high TONAPI limits in your dApps for free You already know our @ton-api/client library — a client for building advanced TON dApps. Now, we're happy to announce a new feature that grants high TONAPI limits for free. This upgrade enables cost-free TON API usage within dApps running in the Tonkeeper built-in browser (mobile) and standard browsers with the Tonkeeper extension installed. To check if this feature is available, verify that the window.tonapi object exists in your browser. How it works →

TonApi V2: Jetton Logo Field Migration Completed The migration of the Jetton logo field in TonApi V2 has been successfully completed today. Now, metadata.image returns the original logo link from the Jetton metadata, while the preview field continues to provide a cached version for display. If you haven’t yet, update your integration to use preview for displaying Jetton logos. Everything else remains unchanged, and no action is required for existing integrations.

TonApi V2: Jetton Logo Field Migration We have made changes to the structure of Jetton data returned by TonApi V2, affecting the way logos are handled. This is particularly important for users working with Jetton images. The migration will be completed on January 15, 2025 What has changed: 1. A new field preview has been added to the JettonInfo object. It contains a link to a cached image of the Jetton logo, specifically prepared for fast and convenient display. 2. The field metadata.image in the JettonInfo object temporarily returns the same cached image as preview. Once the migration is complete, this field will start returning the original link to the logo from the Jetton metadata. We now recommend to display logos using the field: preview Why are we migrating: The goal of the migration is to resolve the mismatch between the original metadata and what our API currently provides. At present, metadata.image returns a cached image instead of the original link. After the migration, the metadata will fully reflect the original data, without any modifications. This eliminates the need for developers to parse contract cells to retrieve original image links. Affected Schema: JettonInfo Affected Methods: • getJettonInfo (/v2/jettons/{account_id}) • getJettons (/v2/jettons) • getJettonInfosByAddresses (/v2/jettons/_bulk)

JettonInfo:
  type: object
  required:
    - mintable
    - total_supply
    - metadata
    - verification
    - holders_count
  properties:
    metadata: # <- will match the original metadata after migration
      $ref: '#/components/schemas/JettonMetadata'
    preview: # <- new field
      type: string
      example: "https://cache.tonapi.io/images/jetton.jpg"
    # ... other fields

Backward compatibility: This change does not break existing integrations—your applications will continue to work without modifications. However, the image URLs for Jettons will point to the original addresses, which may affect image loading speed and the privacy of the end user.

Good news, everyone! We are excited to announce the launch of our webhook service. (Actually, there might still be some issues like delivery delays, but the API is stabilized.) What is it and why do you need it? TON is renowned for its scalability, meaning more transactions and blocks are added to the blockchain every second. In last year's stress tests, a record of 100,000 transactions per second was set. This means the blockchain generated over 100 megabytes of blocks per second or about a gigabit of incoming traffic if you want to view the entire blockchain. Of course, not every service needs to view all transactions in all blocks to find valuable insights. To solve this problem, we are launching a webhook service that allows you to subscribe only to the data you need. Our service will attempt to deliver messages at increasing intervals until your server returns a 200 response. Current subscription options: 1. Subscription to specific accounts - You can subscribe to a million accounts, and if a transaction occurs on any of them, we will notify you. Charges are based on the number of monitored account-days and each event. 2. Subscription to specific opcodes of incoming messages - If any account receives an incoming message with such an opcode, we will notify you. Up to 100 opcodes per account. Charges are based on the number of events. 3. Subscription to new accounts in the network - Don't require description. Charges only for the number of messages. 4. Subscription to the mempool - We send all externals we see before they are included in the blockchain. Charges for each sent message, and no retries. If your server was unavailable, we will not attempt to resend. Try it! Or read the docs first! We welcome any feedback in comments to this post.

Good news, everyone! No more "Something happened but we don't understand what" messages anymore (well, it might still happen occasionally, but not as often). Now we are decoding intentions from external messages on wallet accounts and detecting if they are unsuccessful.

Mintless jettons support TONAPI supports mintless jettons as a part of bigger standard for jettons with custom payload and init data. When you are requesting jetton balances for an account and want to get mintless jettons transparently, you should use the custom_payload parameter in the supported_extension field in the request. For example, this link or direct jetton info this link:

    {
      "balance": "1000000000",
      "wallet_address": {
        "address": "0:405171f583a9e39e22ae9d8394769bc6e37299c59332012a51693b4d606780f3"
      },
      "jetton": {
        "address": "0:fa67d0c7739331fbc3c8f08e018c65f47763616a969100ad760a0b2dc1e36832",
        "name": "Mintless Points",
        "symbol": "Points",
        "decimals": 9,
        "image": "https://cache.tonapi.io/imgproxy/DmmPn6dWmsmBgSMVbvjbhIDCChLWI3RmqDJ71whxYBA/rs:fill:200:200:1/g:no/aHR0cHM6Ly9pLmliYi5jby9TS010TlRHL21pbnRsZXNzLnBuZw.webp",
        "custom_payload_api_uri": "https://claim-api.tonapi.io/jettons/EQD6Z9DHc5Mx-8PI8I4BjGX0d2NhapaRAK12CgstweNoMint"
      },
      "extensions": [
        "custom_payload"
      ]
    }

How to Support Mintless Jettons in Your Dapp 1. Request balances with ?supported_extensions=custom_payload. 2. Check if data["extensions"] contains "custom_payload" for the jetton. 3. If it contains and you want to autoclaim on transaction, when your dapp asks the user to send an outgoing jetton transfer via TonConnect, request custom payload and state init via the API: https://tonapi.io/v2/jettons/0:fa67d0c7739331fbc3c8f08e018c65f47763616a969100ad760a0b2dc1e36832/transfer/UQBDaa8UGaMVKiT8TKXiaJqlyWLmx-MoHYvT_wzHEpdUnIss/payload. 4. Add the received data to the message in your TonConnect request. 5. That's it. Now you support mintless jettons!

Over the past two days, the TONAPI service has been experiencing a significant DDoS attack. This has resulted in some customers encountering 403 errors in rare cases. We are actively addressing this issue and appreciate your patience as we work to resolve it. Thank you for your understanding.

Network activity is higher than usual due to $DOGS minting. You may notice delays in transactions.

Blockchain latency has increased due to the high load resulting from $DOGS claims. Despite these delays, TonAPI remains fully operational.

We just released the first stable versions of the npm packages: 1. @ton-api/client — a new autogenerating client for working with TonAPI, compatible with the @ton/core library. 2. @ton-api/ton-adapter — an adapter for integrating @ton-api/client with the @ton/ton and @ton/core libraries, enabling the use of TonAPI functionality while maintaining the existing code structure. You can check out the example of gasless transactiosns implementation using these libraries: https://github.com/tonkeeper/tonapi-js/blob/main/examples/gasless.ts

🚧 TonAPI Price Index Update Today TonAPI team rolled out an update to the price index. Price index is used to display balances in our products: Tonkeeper, Tonkeeper Pro and Tonviewer. During the upgrade displayed prices for some assets jumped by a few orders of magnitude. Users saw their balances displaying in billions for a few minutes. TonAPI team quickly identified the glitch and deployed the fix immediately. We apologize to all the users for the confusion caused by this issue. We always strive for maximum accuracy of any information that TonAPI provides, however it is important to remember that all the data is provided as is. Prices in particular may be subject to high volatility and arbitrary delays. There are many factors that may impact the displayed prices — for instance, low liquidity tokens price manipulation. If you make trade decisions based on the data offered by TonAPI or any other service, you need to apply your own judgement to make sure the information at hand is accurate and current.
