Preparing for the new v5 version of wallet smart contract

As you know the Tonkeeper team is actively contributing to the development of the TON network. Its previous big contribution was the TON Connect protocol, which eventually became the unified protocol for applications and wallets in the TON network.

In this year, the Tonkeeper team has proposed a new v5-beta version of the wallet smart contract. In beta mode, Tonkeeper Wallet has launched support for this new version.

In addition to retaining the previous functionality (v4), the new contract allows you to send up to 255 messages at a time, as well as to make full-fledged gasless transactions (e.g. payment of network fees when transferring USDt in USDt itself) and other features.

Having studied the contract, we believe it will enhance the usability and capabilities for TON users.

The TON Core team is starting to audit and test this v5-beta smart contract. The smart contract code will change in the course of this work, but we will try to keep its interface intact. The TON Core team plan to complete this work by June 20.

We ask all wallets in the TON ecosystem to support the final smart contract after the audit.

UI:

— Already now wallet teams can start UI preparations. You can use the v5-beta smart contract as a test smart contract, but keep in mind that it will change.

— UI suggestion: wallets that have multi-accounts could support the new v5 smart contract as a separate account in the UI. Provide a “Transfer funds between your accounts” functionality.

Beta:

— If you build v5 functionality into public versions of your products - please mark it as “beta” and do not use v5 contract by default, but only when explicitly enabled in the settings. Please observe this rule to prevent too wide distribution of the non final beta version of the v5 smart contract.

Release:

— The final smart contract will be ready around June 20, after which wallets can enable v5 by default using the final smart contract.
