Rebels Smart Contracts

Build and Test

• npm install
• npx hardhat compile
• npx hardhat test

Structure

• contracts/
  • NightCard.sol, first contract, used to mint initial NFTs and later convert them to revealed Rebels NFTs. Uses a delegated minting module to authorize mints, and calls into the Rebels.sol to reveal NFTs. Also takes payments and allows withdrawal (in NFTBase.sol).
  • Rebels.sol, second contract, allows minting when called from the first contract only. Also stores a provenance hash for fairness verification.
  • NFTBase.sol, base smart contract implementation. Uses openzeppelin's ERC721 implementation. Provides tokenURI() function by using a delegated rendering module.
  • mint/
    • IRebelsMintAuthorizer.sol, used by NightCard.sol to authorize each mint.
    • IRebelsMintInfo.sol, used by minting web UI to display information about the ongoing sale to the user.
    • DutchMintAuthorizer.sol, standard dutch auction authorizer. Linear decrease, no user access checking.
    • MerkleMintAuthorizer.sol, classic whitelist implementation with merkle tree hash checking.
    • MultiMintAuthorizer.sol, stores multiple merkle roots with their respective mint limits and prices. Minting users are matched to the specific MintInfo they are a member of.
  • render/
    • IRebelsRenderer.sol, interface for rendering module; used by NFTBase.sol.
    • BaseURIRenderer.sol, basic token metadata reference.
• test/, smart contracts unit tests
• tasks/, hardhat tasks used for deployment, administration, etc.

Bug Bounty Program

We want Rebels to adhere to the highest quality and security standards in our industry. This is why we're releasing our smart contract source code ahead of the mint and we're announcing our Bug Bounty Program!

Please reach out with any finding at: security@rebels.art. Reports should include: severity, impact, proposed mitigation, and if possible a POC.

Bug bounty rewards will match Immunefi market standards.
