-Cross-chain transfer and other communication are possible due to native support of interoperability. Relayers and on-chain contracts are developed to support that.

+**The BNB Smart Chain** will be:

 - **A self-sovereign blockchain**: Provides security and safety with elected validators.
 - **EVM-compatible**: Supports all the existing Ethereum tooling along with faster finality and cheaper transaction fees.
- **Interoperable**: Comes with efficient native dual chain communication; Optimized for scaling high-performance dApps that require fast and smooth user experience.
 - **Distributed with on-chain governance**: Proof of Staked Authority brings in decentralization and community participants. As the native token, BNB will serve as both the gas of smart contract execution and tokens for staking.

+# 1.Background
+This is to support some projects with customized tokens that they want to integrate into the BSC faucet tool.
+
+## 1.1. How to Integrate Your Token
+- Step 1: Fund the faucet address by sending a specific amount of your BEP-20 token to the faucet address (0xaa25aa7a19f9c426e07dee59b12f944f4d9f1dd3) on the BSC testnet.
+- Step 2: Update this README.md file and create a Pull Request on [bsc github](https://github.com/bnb-chain/bsc) with relevant information.
+
+We will review the request, and once it is approved, the faucet tool will start to support the customized token and list it on https://www.bnbchain.org/en/testnet-faucet.
