MaraScan Contract

This contract was written in purpose of a Hackathon. Security issues may not be analyzed correctly, use cautiosly

Concepts of the MaraScan Contract?

  • It is an upgradeable UUPS contract
  • Accepts USDC (central cuurency) Token from donor and disbures equally to beneficiaries
  • Accepts ETH from donor, swaps Exact ETH to USDC and disbures equally to beneficiaries
  • Accepts anyother approved tokens and swap Exact Token to USDC and disbures equally to beneficiaries

Disburesement

function _disburseToken(
        address _tokenAddress,
        uint256 _amount,
        address[] calldata _beneficiaries,
        bytes memory _category
    ) internal {
        uint256 amountPerBeneficiary = _amount / _beneficiaries.length;
        for (uint256 index = 0; index < _beneficiaries.length; index++) {
            require(
                ERC20(_tokenAddress).transfer(
                    _beneficiaries[index],
                    amountPerBeneficiary
                ),
                "Unable to transfer token"
            );
        }
        // Disbursement ends

        // Mint Badge
        IBadges(BADGE).mintBadge(0, msg.sender, _category);
        emit Disbursed(msg.sender, _amount, _beneficiaries);
    }

Upon disbursement of USDC, an ERC1155 is minted to Donor.

    IBadges(BADGE).mintBadge(0, msg.sender, _category);
