A Solidity smart contract enabling a manual referral program with token rewards for referrers.
The Referral Program Smart Contract is a Solidity-based contract designed to facilitate a token reward system for user referrals. Managed by an owner, it allows users to be assigned referrers and distributes rewards when referrals meet predefined conditions. The contract ensures that each user has only one referrer and prevents self-referrals or duplicate claims. The owner manually sets referrals and distributes rewards, making it a simple yet effective solution for implementing referral-based incentives in blockchain applications
