PONG? was created to differentiate from our inspiration PENG! - the pioneering x402 implementation on BNB Chain. While PENG! blazed the trail, PONG? adds its own unique twist with the question mark symbolizing curiosity, exploration, and the experimental nature of gasless payments. We're not competing - we're contributing to the ecosystem PENG! helped create.
PONG? builds upon the groundbreaking work of PENG!, which represented the first successful implementation of the x402 protocol on BNB Chain. This was made possible through the integration of EIP-2612 Permit signatures, opening new possibilities for gasless payments on BNB Chain and other EVM-compatible chains.
The x402 protocol has evolved significantly with the recent addition of EIP-2612 Permit support. This enhancement was officially merged into the main x402 repository through Pull Request #485, expanding the protocol's capabilities beyond the original EIP-3009 USDC implementation.
Previously, x402 was limited to chains supporting EIP-3009, which excluded networks including BNB Chain, since Circle did not deploy native USDC on it. With the addition of EIP-2612 Permit support, any token that implements the permit function can now be used with the x402 protocol, dramatically expanding its reach and utility.
PONG? operates as a USD1 facilitator on BNB Chain, enabling gasless token distribution through cryptographic signatures. We implement off-chain signature authorization using EIP-2612's permit() function with domain-separated typed data (EIP-712), enabling meta-transactions where our backend submits the on-chain transaction while you sign off-chain.

The x402 protocol enables gasless payments through cryptographic signatures, eliminating the need for users to hold native tokens for transaction fees. This creates a seamless payment experience while maintaining security through cryptographic verification using EIP-712 domain separation.
All payments are cryptographically verified using EIP-2612 Permit signatures, ensuring that only authorized transactions are processed. The facilitator contract handles the settlement process securely and transparently. Every signature is domain-separated and bound to specific parameters including amount, deadline, and nonce.
The x402 protocol is fully open source and community-driven. The recent addition of EIP-2612 Permit support demonstrates the protocol's commitment to innovation and broader blockchain ecosystem compatibility.

⚠️ IMPORTANT: PONG? is a demonstration token with no utility, value, or purpose beyond showcasing the x402 protocol implementation. It is not a financial instrument, investment opportunity, or store of value.
Minting Information: PONG? tokens can be minted through three endpoints:
/pong1 - 4,000 PONG? for 1 USD1/pong5 - 20,000 PONG? for 5 USD1 (Most Popular)/pong10 - 40,000 PONG? for 10 USD1All endpoints provide a rate of 4,000 PONG? per USD1. The entire payment amount goes to sustaining operations and keeping the facilitator running.
Fair Launch: PONG? features a fair launch with no team allocation, no founder tokens, and 100% of proceeds going to liquidity. The team reserves the right to refund sybils and suspicious addresses to ensure fair distribution.

Special thanks to the PENG! team for pioneering x402 on BNB Chain and proving that gasless payments are possible on networks beyond those supporting EIP-3009. PONG? stands on the shoulders of giants.
Thanks to the x402 protocol developers and the broader Ethereum community for creating the standards (EIP-2612, EIP-712) that make this possible.
