Hey! If you are a developer with experience with smart contracts, then this offer is for you.

 

Free TON is a decentralized multi-blockchain that develops thanks to the efforts of the community. Developers support is needed now. A contest with decent rewards was created and adopted. I'll tell you about it now.

 

According to the conditions of the contest, it is necessary to develop a system with regular payments (subscriptions) for Free TON for TIP-3 tokens and for TON Crystal.

 

Contest dates:

 

27.05.2021 00:00 UTC — 27.06.2021, 23:59 UTC

 

Motivation:

 

Monthly subscriptions are a key monetization channel for legacy web, and arguably they are the most healthy monetization channel for businesses (especially when compared to ad/surveillance) based models. But in the blockchain world there haven’t been any successful full-featured crypto subscription payment systems yet. For these reasons, I think it’s worth creating smart contracts to do ‘subscriptions’ on Free TON to facilitate user experience in crypto for both users and product owners (service providers).

 

General 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 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. Existing examples: 

 

Solc: https://github.com/tonlabs/ton-client-js/blob/master/packages/tests/contracts/abi_v2/Subscription.sol 

C++: samples/cpp/Wallet at master · tonlabs/samples · GitHub

 

Contest rewards:

 

 1. 50 000 TON (about $22 000)

 2. 40 000 TON (about $17 600)

3.  30 000 TON (about $13 200)

 4. 20 000 TON (about $8 800)

 5. 10 000 TON (about $4 400)

 

Also participants who receive 6th-10th place, receive points and do not have “rejected” votes will receive a consolation prize of 2 000 TON (about $880).

If you know how to develop smart contracts, then this offer is for you. Now there is extremely low competition, in this regard, it will not be difficult for you to take one of the first 5 prize places.

Good luck to everyone!
