intellij-t-sol VS ever-sdk-js

T-Sol (short for Threaded Solidity), which is designed to make writing TVM-based smart contracts more comfortable and faster, is based on Sergey Tselovalnikov's original Solidity plugin and includes syntax prompts, autofilling capabilities and other features. The plugin is also open-source (https://github.com/broxus/jetbrains-t-sol) and was released under the MIT license.

Users don’t have to read a complex whitepapers to assess service in Free TON (as opposed to utility tokens) Users should have ability to subscribe and cancel anytime, without having to own any specific tokens Don’t have to understand the product owners vesting schedules, crypto-economics, or anything more complex than the DeBot/Smart Contracts use case. Product owners can get a consistent, ongoing stream of cash flow while assessing the health of their business (subscribers, churn, growth) Product owners can focus on making customers happy, as opposed to splitting time between speculators and users Product owners utilize a proven, time-tested business model Task Implement on-chain Recurring Payments (‘Subscriptions’) smart contract system by which FreeTON users will be able to pay to unlock access to special DeBots/Smart Contracts/Off-chain service for a certain amount of time. Users must be able to recurly pay by TON Crystal or TIP-3 token (e.q. USDT) to subscribe for DeBots/Smart Contracts and be able to cancel or pause subscription anytime. In turn, DeBots/Smart Contracts owners must be able to track subscribers to unlock DeBots/Smart Contracts usage or some of its features.
