Toncenter extended plans

We have done extensive work on upgrading the Toncenter infrastructure and are happy to note that now more than 100 servers are running on our system. In addition, we have implemented the ability to dynamically add new ton-http-api instances in runtime.

In order to be able to provide you with the expected level of performance we are introducing extended plans:

— Free: 1 API Key, 10 RPS;

— Plus: 3 API Keys, 25 RPS, Privately hosted Liteservers, 5.9 TON / month;

— Advanced: 10 API Keys, 100 RPS, Privately hosted Liteservers, 59 TON / month;

Free open source code is still available, so you can run a fully functional api yourself.

We guarantee that a free plan will always exist at toncenter.com, for a quick start for developers. However, if you are developing a popular service or a service that needs high uptime, we recommend that you consider an extended plan.

You can check out the plans in our bot @tonapibot.

Since launch of A Careers is coming, we are opening A Careers smart-contracts for a public review and judgement. Still some minor fixes possible, but in general it is 100 percent ready and working. Happy for any commitments or contributions.

https://github.com/the-real-some-dao/a-careers-smc

Remind you that you can become a beneficiary of the protocol, playing our clicker game @A_CLICKER_BOT

A contract for managing this and similar dApps is coming next. Stay tuned 🚀.

🔧 Introducing TON Replay

As our blockchain ecosystem thrives with countless developers and projects, evolving becomes a cautious task. Changes could unpredictably impact the ecosystem, making upgrades a slow and meticulous process. Often, theoretical issues might not even affect real-world applications.

🌟 But, there's a breakthrough! TON Core has launched the TON Replay project to tackle this challenge. The first fruit of this initiative is TonTVMReplay, developed by DTON. This tool emulates historical transactions on updated versions of the TON Virtual Machine (TVM). This means we can now test how real projects react to upgrades or network configuration changes before implementing them, ensuring smoother and safer evolution.

🔍 Looking Ahead: TON Replay isn't stopping there. We're developing advanced features for smarter checks. The goal is to ensure the practical outcomes of transactions—like transfers, swaps, and more—remain consistent, even if the transactions themselves change. This will enable us to run mirror networks and make significant, yet safe, modifications to the transaction executor.

🛠 More from DTON: Besides TonTVMReplay, DTON is also behind other developer-friendly projects, such as their blockchain index dton.io and the recently launched LSaaS (liteserver-as-a-service) via @liteserver_bot.

🏆 MyTonWallet Contest for iOS Developers

Prize fund: up to $25,000
Deadline: 23:59 on March 28th (Dubai time)
Results: April 12th, 2024

The Task is to implement the new design for MyTonWallet as a new Swift app based on the provided mockups and archive with animations. Your submission must precisely represent the provided design – this includes all elements, their proportions and position on the screen, as well as their animations and transitions.

Required Functionality (Screens)
1. Auth Flow, including both creating and importing wallets.
2. Main Screen listing all user's tokens and recent transactions.
3. Transaction Info Modal featuring several transaction types.

Details
While the task involves developing a new Swift app, some existing code from our current JavaScript app must be reused. Specifically, the API and blockchain integrations (which is already standalone and currently exposed as a web worker). To achieve this, a bridge must be implemented to allow running JavaScript process from the Swift environment (e.g., in an invisible WebView). This approach enables leveraging our existing API abstractions and focusing on the UI part without delving deeply into blockchain-related programming.

Evaluation Criteria
During the evaluation stage our judges will test the submissions on a broad range of iOS devices. The key factors that will be used to determine the best apps are:

· The general aesthetics of the app.
· Adherence to the provided mockups and design elements.
· Attention to the tiniest details in the user experience.

The smoothness of animations and the overall stability of the app will play a major role. Last but not least is the absence of significant flaws (including crashes, performance issues, battery drains, visual glitches, noticeable element blinking, layout imperfections and more).

Submissions
Contestants will be able to submit their entries to @MyTonWalletBot. We will further clarify the submission instructions closer to the deadline.

@ton/core update 0.56.2

Fixed cell serialization and hashes calculation for PrunnedBranch exotic cells.

Developers, please pay attention to cell hashes in your projects.

Big thanks for @yungwine and @Gusarich for reporting this

tonutils-go v1.9.1 released, please update

Update is needed because:
A new version of LiteServer has been deployed to the testnet that changes the way it proves block shard information for GetBlockShardsInfo method. This update removes the state proof in the second root and uses only a single root with block proof. As a result, this new LiteServer version is incompatible with previous versions of LiteServer and proof verification of GetBlockShardsInfo fails.

v1.9.1 supports both LS versions, it is safe to update for both networks
