NFT（Non-Fungible Token）

NFTs sold in the marketplace are developed based on the ERC721 standard. In addition to tickets for live concerts and events, NFTs are also being considered for use in token-gated commerce and token-limited communities.

5.3 About Smart Contract Security

All smart contracts adopted by the Fanpla system are security checked by a specialized contract auditing company. In addition, OpenZeppelin, which is used in many projects, is mainly adopted to implement security measures.

5.4 About Meta-Transactions

FPL realizes gasless transactions by independently implementing the Permit function based on the ERC2612 standard for FPL and the ERC4494 standard for NFTs. Users do not need to prepare the crypto asset POL when purchasing NFTs in the marketplace, and can use it without being aware of gas charges. We are designing the Fanpla system to eliminate as many difficult operations unique to Web3.0 as possible, not only in the marketplace, but also in the Fanpla system, and are working to improve the user experience.

5.5 About Marketplace Specifications

Fanpla Market controls buying and selling on external marketplaces on smart contracts in order to reliably return royalties to artists. By utilizing the marketplace to purchase items such as tickets, fans not only ensure that artists receive their royalties reliably but also help prevent illegal resale. Additionally, this creates a new source of revenue for funding their activities.
