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
-
Send simple message from FreeTON to Ethereum blockchain and vice versa - Transferring tokens between FreeTON ↔ Ethereum chains
- Distribution of relayer responsibilities, economy model implementation
- 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
