Free TON

Contest: Ethereum↔FreeTON Bridge Implementation Stage 2

Contest dates

  • Submission period: 1 calendar month after approving this proposal in the governance interface;
  • Judging period: 2 weeks after the submission period.

Short description

Implement stage 2 of the winning architecture of the Ethereum↔FreeTON Bridge Design and Architecture contest with the milestone “Transferring tokens between FreeTON ↔ Ethereum chains”.

Type

Chained contest

Stages

  1. :white_check_mark: Send simple message from FreeTON to Ethereum blockchain and vice versa
  2. Transferring tokens between FreeTON ↔ Ethereum chains
  3. Distribution of relayer responsibilities, economy model implementation
  4. Staking, Rewards and slashing

Motivation

A significant challenge of blockchains to date is their lack of interoperability. Once a developer builds their decentralized application on any particular platform, they’re generally locked into that platform with no opportunity to leverage any of the benefits of other blockchains.

We believe that the future of blockchain technology is to allow all major networks to interact with one another and to be able to share value and information.

Both ecosystems, Ethereum and FreeTON share these views and we want to add the possibility to interoperability through the cross-chain message-passing protocol, thus we open up many opportunities for awesome projects in the market of DeFi.

FreeTON is delivering a decentralized and fair internet where users control their own data, identity, and destiny. Building a bridge with Ethereum will allow FreeTON to reach a whole new level.

General requirements

Your submission should include:

  • Trustless and non-custodial transfer of ERC20 tokens from Ethereum network to Free TON
  • Graphical interface with support of a browser wallet (e.g., Metamask) to facilitate tokens transfer for a user
  • Open sources published at GitHub/GitLab or another open repository

Fair play

As per Procedural remarks on contests.

I was surprised to find that not a single person from external jurors was included in the contest contract. Accordingly, there is no way to take part in jureing.

Hi!

I am an external jury (pk: 6ff61c1a7bb09795f7b5d5514dd710efb72e9557654d362ef208fde545ba7a33, address: 0:612410a54714de99c56eead2d1a4c2a3afdf2edcc392c9d7120f1505b666770d), but my key is not added to the contest smart-contract. Please add my key to the contract ASAP, because judging period is going to end soon.

That’s weird, as we definitely asked the interface group to do this. Will check what can be done

Супер :3 отлично проделанная работа
