Build a decentralized token bridge that realizes cross-chain transfer of ERC-20 tokens between EVM chains and aelf chain.
Requirements:
- The bridge should enable the transfer of tokens between EVM chains and aelf chain at one click, with no need for redevelopment.
- The token standard supported is ERC-20.
- Cross-chain protocol layer needs to be extremely secure (code needs to be open-source for review).
- The bridge should be compatible with aelf wallets and MetaMask at least.
- A team able to undertake development and operation is favored.
Judging Criteria:
The protocol layer should realize ERC-20 token cross-chain transfer between Ethereum (or other EVM chains) and aelf. Contracts receive review.
Prize: 5,000 USDC.
- The ERC standard for cross-chain is met.
- A valid and open-source contract code on GitHub is provided.
- Pass the security review by aelf team.
- Whitepaper (design doc) that describes the token cross-chain mechanism is provided.
The application should realize ERC-20 token cross-chain transfer between Ethereum (or other EVM chains) and aelf, with user-friendly UI and good UX.
Prize: 5,000 USDC.
- Provide the link for a demo video that presents token cross-chain transfer between EVM chains and aelf.
- Good UX for token cross-chain interactions.
- UI design provided.
- Frontend and backend code repo submitted.
