# x402/x405 Protocol

#### **1.x402 Protocol: An open protocol for internet-native payments**

**site:**[**https://x402.bigpump.ai/**](https://x402.bigpump.ai/)

bigpump currently supports the X402 standard protocol, an extension based on CoinsBase via XLayer. It facilitates the issuance of X402 standard tokens and the creation of Meme assets on XLayer, making it ideal for new narrative, lightweight, and community-driven projects.

CoinBase x402 Protocol: <https://www.x402.org/>

Xlayer x402 Protocol:&#x20;

Facilitator: <https://facilitator.questflow.ai/>

* **Token Name:** \[Your Token Name]
* **Token Symbol:** \[Your Token Symbol]
* **Token Description:** \[Briefly describe the token's purpose or project vision]
* **Token Icon:** Upload or generate the token icon
* **Total Supply:** Default 1,000,000,000
* **Buy/Sell Fee:** Default 1%
* **Payment:**&#x55;sers can create or mint tokens with 0 Gas, facilitated by the x402 protocol. During the token minting process, the initial mint rate is 1 USDT = 5000 Tokens. For every additional 10,000 USDT added to the liquidity pool, the token output decreases by 100.
* **Initial Liquidity Pool Injection:** When the internal liquidity reaches $100,000, it will automatically be added to the swap, and the initial liquidity will be permanently locked.
* The x402 protocol currently supports Xlayer Chain.
