Cosmos Unwrapper Approval

This example demonstrates how to create an approval that allows the Cosmos coin wrapper address to send badges back to users, enabling conversion from Cosmos coins back to badges (unwrapping).

You pretty much: 1) figure out your address and 2) figure out a path that users can send from this address without needing the address to control its approvals.

Code Example

export const unwrapperApproval = ({
    specialAddress,
    badgeIds,
    ownershipTimes,
    approvalId,
}: {
    specialAddress: string;
    badgeIds: iUintRange<bigint>[];
    ownershipTimes: iUintRange<bigint>[];
    approvalId: string;
}): RequiredApprovalProps => {
    const id = approvalId;
    const toSet: RequiredApprovalProps = {
        version: 0n,
        fromListId: specialAddress,
        fromList: AddressList.getReservedAddressList(specialAddress),
        toListId: 'All',
        toList: AddressList.AllAddresses(),
        initiatedByListId: 'All',
        initiatedByList: AddressList.AllAddresses(),
        transferTimes: UintRangeArray.FullRanges(),
        badgeIds: badgeIds,
        ownershipTimes: ownershipTimes,
        approvalId: id,
        approvalCriteria: {
            ...EmptyApprovalCriteria,
            overridesFromOutgoingApprovals: true,
        },
    };

    return toSet;
};
