x402 (X402) is a token launched in 2025 that operates on the BNB Smart Chain (BEP20). It is categorized as a meme token within the BNB chain ecosystem. Some low-confidence sources describe it as a blockchain payment protocol for AI and robots to send money without human intervention.

To buy X402 safely, you must use the correct contract address: 0x1e8e4145506e74996f32b61de2f7f4ec60f2d102. Using a lookalike address or the wrong network can lead to a permanent loss of funds.
