Mintless jettons support

Toncenter supports mintless jettons, check on preview.toncenter.com!

Now for jettons that allow mintless claim v3/jetton/wallets API returns additional field:

"mintless_info": {
    "amount": "<amount-as-string>",
    "start_from": <unix-timestamp>,
    "expire_at": <unix-timestamp>
}

How to support mintless jettons in your dapp?
— To show balance with mintless, use data["balance"] + data["mintless_info"]["amount"]
— To autoclaim on transaction, when your dapp asks user to send outgoing jetton transfer via TonConnect, check if data["mintless_info"] is present and retrieve from mintless jetton claim api custom_payload and init_data to fill them in to transfer.
— That's it. Now you support mintless jettons!


P.S. Note that now code_hash and data_hash fields can be null for not yet deployed jettons wallets.

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!

TON Mintless Jettons

Introducing the new TON Mintless Jetton technology. It is a jetton that can be instantly distributed to hundreds of millions of users on the TON blockchain, with network fees costing less than a dollar. The user's ownership of their coins is guaranteed by cryptography and a smart contract.

As an example, we created a test jetton called Mintless Points (for testing purposes only, no other value) and distributed it to 18 million wallets in the TON mainnet.

This jetton is compatible with regular jetton in TON. The only difference is that the smart contact is not created in advance, but during the user's first action.

Popular TON ecosystem products such as Tonkeeper, MyTonWallet, Tonviewer, Tonscan.org, TON API, DTON, Toncenter have announced that they will soon support Mintless Jetton technology.

We encourage all products and services in the ecosystem to consider integration as well.

On September 26, the famous game project Hamster Kombat will apply this technology during its coin giveaway. Considering Hamster Kombat's gigantic audience, this event has all chances to become the largest airdrop in the history of cryptocurrencies.

🎉 Tact v1.5.0 has just been released

The new Tact release v1.5.0 just landed on NPM! Here are the highlights of the most important features.

🛠 New Tact features

asm functions allow you to access the deep dark corners of TVM for more features or better performance:

asm fun keccak256(s: Slice): Int {
    1 INT HASHEXT_KECCAK256
}

asm functions have some limitations at this point and the Tact team will make them even more powerful in the next releases.

- A wider range of serialization options for integers can now be used, not just 8, 16, 32, 64, 128 and 256-bit integers, but anything in between: uint1 through uint256 and int1 through int257. For instance, a 48-bit timestamp can be defined now if you'd like to build contracts that can work after the year 2038:

contract Contract {
    timestamp: Int as uint48
}

- Constant definitions now support calls to user-defined functions and references to other constants:

const CONSTANT: Int =
    myFunction(OTHER_CONSTANT)

👩‍💻 New builtin and stdlib functions and methods

- The exists method for the Map type: m.exists(key) which is equivalent to m.get(key) != null.

- The deepEquals method for the Map type: m1.deepEquals(m2) -- you can now easily compare two maps with the same key-value pairs and get true as the result, even if their internal representations are different, so the hash-based == comparison would return false.

- The toSlice method for structs and messages: struct.toSlice().

- The new slice, rawSlice, ascii and crc32 built-in compile-time functions to help you define constant integers and slices more conveniently.

- The new stdlib functions to help with fee calculations: gasConsumed, getComputeFee, getStorageFee, getForwardFee, getSimpleComputeFee, getSimpleForwardFee, getOriginalFwdFee, myStorageDue. This brings you access to the TVM instructions from 2023.07 and 2024.04 upgrades.

- The parseStdAddress and parseVarAddress stdlib functions allow you to parse slices into structured addresses.

🐞 The new release also includes a bunch of bugfixes. Thanks to all the Tacticians for all the issues you open!

TVM Debugger

I have just released an early version of TVM Debugger, which will allow developers to debug their TON contracts as they would debug any regular program - line by line, with breakpoints and variable inspection.

You are welcome to try it out - just look at this example repo.

If you have any feedback, suggestions, bug reports, or anything else of that sort, do not hesitate to post it in the discussion of this post, or simply DM me.

The implementation of the debugger is definitely a little dirty in some places at the moment, so please don't judge the quality of code too harshly yet.

If you would like to learn about the inner workings of the debugger, or about the features that may be implemented in the future, please read this post.

🎉 Tact 1.4.4 has just landed on NPM!

Fixed a few bugs and added AST equality comparison API mostly for third-party tools, like the misti static smart-contract analyzer. The API also be used to compare contracts without taking into account whitespace, comments or even order of definitions and declarations.

More details as always can be found in the changelog.

🎉 Tact 1.4.2 has just landed on NPM!

🐞 We fixed a few type-checking and code generation bugs. One of the most important fixes is that getters again return flattened types for structs as it used to be. We broke it while trying to allow structs with more than 15 fields. Please give it a try and let us know if the issue is gone now — all your bug reports are really appreciated.

🛠 A bunch of the other changes include improved support for the misti static smart-contract analyzer — give it a try, it’s in early stage of development but already found some issues in soon-to-be released projects.
