ISSP is the first cross-chain inscription protocol system that integrates an inscription marketplace and inscription swap, leveraging the unique Objects model of Sui network to naturally benefit inscription systems. ISSP has initially launched the SUI-20 inscription standard protocol on the Sui network, utilizing the network node's built-in indexer to index inscription data. This ensures the highest performance and the most stable inscription experience. ISSP supports seamless inscription deposits into exchanges, eliminating the need for additional development by exchanges to integrate the inscription protocol.
