INSTRUCTIONS

Build a decentralized token bridge that realizes cross-chain transfer of ERC-20 tokens between EVM chains and aelf chain.

Requirements:

  1. The bridge should enable the transfer of tokens between EVM chains and aelf chain at one click, with no need for redevelopment.
  2. The token standard supported is ERC-20.
  3. Cross-chain protocol layer needs to be extremely secure (code needs to be open-source for review).
  4. The bridge should be compatible with aelf wallets and MetaMask at least.
  5. 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.

  1. The ERC standard for cross-chain is met.
  2. A valid and open-source contract code on GitHub is provided.
  3. Pass the security review by aelf team.
  4. 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.

  1. Provide the link for a demo video that presents token cross-chain transfer between EVM chains and aelf.
  2. Good UX for token cross-chain interactions.
  3. UI design provided.
  4. Frontend and backend code repo submitted.
