# Token Protocol & Core Contracts

### BBEP-20 Protocol <a href="#bbep-20-protocol" id="bbep-20-protocol"></a>

A novel, open-source, and non-upgradable token standard defined by Beef. Unlike standard BEP-20 tokens, BBEP-20 integrates an external call function within its contract to power the decentralized referral rewards system. All tokens launched on Beef feature a unique identifier: their contract addresses end with the suffix beef.

### Core Contracts <a href="#core-contracts" id="core-contracts"></a>

Beef consists of three main contracts:

1. **BeefLauncher:** The platform’s core contract (open-source), featuring four key functions: Bind Referrals, Deploy Tokens, Reward Distribution, Collect LP Fees.
2. **BeefLocker:** Permanently locks LP tokens for projects launched on Beef while allowing LP fee collection.
3. **ClaimRewards:** A dedicated contract for users to self-custodially claim their earned rewards (referral fees, holder dividends, etc.) on-chain.
