# System Architecture The exchange for TreasureNFT consists of a hybrid off-chain/on-chain system in which taker orders are matched with maker orders to execute NFT transactions. TreasureNFT is a combination of blockchain technology and NFT asset circulation. The platform adopts mature technical solutions that have been generally proven and tested in long-term practice. It provides the platform with data services with high processing power and low latency for smart contracts. In the future, it can support millions of users, and easily achieve bug recovery and upgrade, as well as good scalability. This is a non-custodial exchange and orders require approval of tokens (fungible and non-fungible) to be transferred in the exchange. Off-chain orders ("Maker Orders") are EIP-712 signatures stored off-chain. A transaction consists of a bilateral exchange of a specific amount of ERC-20 tokens for NFT tokens (e.g. ERC-721, ERC-1155) at a specific price. It also supports traditional cryptocurrency exchange and continues to expand the trading asset category, and in each transaction, transaction fees can be used as (1) agreement fees and/or (2) royalties. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
